Every experienced B2B buyer who sources products from China can recall at least one difficult conversation about payment terms. The factory wants 30% upfront, another 70% before the goods leave the warehouse. The buyer wants net 60, documents against acceptance, or some arrangement that gives them a little more control over what happens if the shipment does not arrive as described. Neither side is being unreasonable. Both sides are managing real financial risk, and payment terms are the mechanism through which that risk gets allocated between two parties who may have only known each other for a matter of weeks.

Quick answer. Terms are earned in steps tied to evidence, not time. First order runs 30/70 with tooling paid in full. A clean pre-shipment inspection commonly moves it to 20/80. Net 30 usually arrives in year two on repeat SKUs only. Net 60 with a credit limit is a year-three arrangement. Asking for open account on a first order tells the factory you have not priced their risk.

This guide is written for brand owners, private label buyers, and importers who are sourcing adult wellness products from Chinese OEM and ODM manufacturers. It covers every common payment structure you will encounter in this trade — telegraphic transfer, letter of credit, documentary collection, open account, escrow, and milestone-based structures for large custom development projects. It explains how each mechanism works mechanically, what each one means for your cash flow and risk exposure, how to negotiate improvements as your supplier relationship matures, and how to recognize the warning signs that should make you walk away from a payment request entirely.

The adult wellness category has its own nuances in this context. It is a category where many Chinese manufacturers have historically operated at the smaller end of the market, where trust-building happens faster when buyers understand factory economics, and where payment term disputes are among the most common friction points in early-stage supplier relationships. Understanding the logic behind standard Chinese factory payment terms — not just the mechanics but the underlying risk calculus — puts you in a far stronger negotiating position than treating payment terms as a bureaucratic formality.

Why Payment Terms Are a Risk Management Tool, Not Just a Finance Decision

Most buyers approach payment terms as a cash flow question: how late can I pay? Most factories approach them as a credit risk question: how much exposure am I willing to carry with an unknown counterparty? Both framings are incomplete. Payment terms are fundamentally a risk allocation mechanism, and understanding what risks each party is actually managing explains why certain structures exist and under what conditions they change.

From the factory side, the core risks are: the buyer cancels the order after raw materials have been purchased; the buyer disputes quality after goods are produced and refuses to pay the balance; the buyer accepts the goods, takes delivery, and then delays payment or disappears. Each of these scenarios is a real loss for the factory, not a theoretical one. Chinese adult wellness manufacturers, particularly those with custom tooling and OEM production capacity, often carry significant upfront costs for a buyer order before any goods are produced — raw material procurement, tooling fabrication, mold creation for custom products, and the opportunity cost of production capacity allocated to that order.

From the buyer side, the core risks are: the factory ships goods that do not conform to specifications; the factory substitutes cheaper materials after samples were approved; the goods arrive damaged or short-shipped; the factory delays shipment and the buyer has already paid in full. These are also real risks, particularly for buyers who have not yet established a track record with a specific supplier.

When you understand the risk structure on both sides, you can have a different kind of conversation. Instead of negotiating payment terms as a positional argument — you want more control, they want more security — you can frame the discussion around what evidence and mechanisms would allow each party to reduce their exposure. That framing leads to better outcomes and better relationships than simple price-style haggling over payment percentages.

The Standard New-Buyer Structure: T/T 30/70

The default payment structure offered by virtually every Chinese adult wellness manufacturer to a new buyer is telegraphic transfer with a 30% deposit paid before production begins and the remaining 70% paid before shipment — commonly written as T/T 30/70. If you have sourced anything from China before, this structure is familiar. Understanding why it is the default — from the factory's perspective — is the foundation for negotiating effectively.

The 30% deposit serves a specific function: it covers the factory's raw material procurement costs and provides proof of buyer commitment. For an adult wellness product manufacturer, raw materials include silicone, ABS plastic, motors, electronic components, charging hardware, and packaging materials. These are purchased specifically for the buyer's order, often to the buyer's custom specifications. Without a deposit, the factory bears 100% of the cost of a buyer who places an order and then cancels, changes their mind, or simply goes quiet. The 30% deposit is sized to approximately cover or slightly exceed typical raw material costs for most product categories, though this varies by product complexity.

The 70% balance before shipment reflects the factory's assessment of post-production risk. Once goods are produced and packed, the factory has invested 100% of its production cost. If the goods leave the warehouse before full payment is received, the factory is relying entirely on the buyer's willingness to pay upon arrival — with no leverage remaining. For a factory dealing with a new, unknown buyer in a foreign market, this is an uncomfortable position. The goods have already been customized, often with the buyer's private label branding, meaning they cannot easily be sold to another customer. The 70% before shipment structure ensures the factory is paid in full before surrendering control of the goods.

Experienced buyers sometimes find this structure frustrating, particularly if they have a strong track record with other Chinese suppliers. The factory does not know your track record with other suppliers. They know their track record with buyers who promised to pay and did not. T/T 30/70 is not an expression of distrust — it is the rational default for managing counterparty risk with an unknown party, and it is the same logic that underlies payment term structures in many other industries when dealing with new customers.

Telegraphic Transfer: Mechanics and Practical Implications

Telegraphic transfer — T/T — is a direct bank-to-bank wire transfer. In the China trade context, this almost always means a SWIFT transfer, using the Society for Worldwide Interbank Financial Telecommunication's messaging network to route funds from the buyer's bank to the factory's bank account.

Mechanically, a T/T works as follows. The buyer initiates a wire transfer from their bank account, providing the factory's bank details: bank name, bank address, SWIFT/BIC code, account number or IBAN, and the account holder name. The buyer's bank sends a SWIFT message through the network to the factory's correspondent bank or directly to the factory's bank, depending on whether a direct relationship exists between the two institutions. In most cases, there are one or two intermediary banks in the chain, each of which may charge a handling fee — typically USD 15 to USD 35 per transaction. Processing time is typically one to three business days from initiation, though transfers to Chinese banks from some jurisdictions take longer due to additional compliance screening.

Bank charges are borne by both parties in the typical structure. The buyer pays outgoing wire fees at their own bank (commonly USD 25 to USD 50 for international SWIFT transfers, depending on institution). The factory's bank may deduct an incoming transfer fee from the received amount. In some cases, intermediary correspondent banks also extract fees. This means the factory may receive slightly less than the buyer sent, which becomes relevant for precise settlement. Professional factories handle this by either building a small buffer into their quoted prices or specifying in their proforma invoice that the buyer bears all bank charges on both ends — a clause sometimes written as "OUR" charges in SWIFT terminology, meaning the sender covers all charges.

Operationally, T/T 30/70 works as follows. The factory issues a proforma invoice (PI) specifying the total order value, the 30% deposit amount, and production lead time. The buyer transfers the 30% deposit and sends the buyer's bank transfer receipt to the factory as confirmation. Production begins upon deposit receipt confirmation. When production is complete and goods are packed, the factory issues a commercial invoice and a packing list and notifies the buyer that the balance is due. The buyer transfers the remaining 70%. Upon confirmation of the balance transfer, the factory releases the goods to the freight forwarder and shipment proceeds.

The timing of when the 70% balance is "due" is a point worth clarifying carefully. T/T 30/70 in its strictest interpretation means the balance is due before shipment — before the factory has even handed the goods to the freight forwarder. A common first improvement in terms as the relationship develops is shifting to 70% against copy of bill of lading, which means the buyer pays the balance after receiving a scanned copy of the signed bill of lading from the factory. This gives the buyer confirmation that the goods have been shipped before releasing the final payment. The factory still retains control of the original bill of lading — and therefore the goods — until payment is confirmed, because the carrier will not release goods at destination without the original bill of lading. This structure is a meaningful improvement for the buyer with minimal additional risk to the factory.

Improving T/T Terms as the Relationship Develops

Payment term improvements with Chinese factories follow a predictable progression, and understanding what milestones justify each step helps you plan your negotiation strategy over time rather than trying to get the best terms on order one.

The typical progression looks like this. Orders one through three with a new factory are usually conducted on T/T 30/70 before shipment — the standard default. If those orders complete without disputes, delivery is on time, and quality is consistent with samples, the factory has accumulated positive evidence about your reliability as a counterparty. At this point, it is reasonable to request a shift to T/T 30/70 against copy of bill of lading. Most factories will agree to this adjustment after two or three successful orders because the change in their risk exposure is small — they still hold the original bill of lading — while the gesture builds goodwill with a reliable buyer.

After five or more successful orders with a factory, or after your annual purchase volume with that factory exceeds a meaningful threshold (typically USD 50,000 to USD 100,000 annually), you can begin discussing net payment terms on the balance. A common intermediate structure is 30% deposit with the 70% balance net 30 days after bill of lading date. This gives the buyer a 30-day payment window on the majority of the invoice, which is meaningful for cash flow management when goods take 20 to 35 days to arrive by sea freight. The factory accepts this because they have concrete evidence of your payment reliability across multiple prior orders, and the relationship value of retaining a consistent buyer outweighs the 30-day financing cost on the receivable.

For very high-volume buyers with multi-year relationships, factories will sometimes offer 30% deposit with net 60 on the balance, or even reduce the deposit to 20%. These structures are not common and are typically accompanied by a formal credit review of some kind — the factory's finance team assessing your business stability, purchase history, and payment behavior. Do not expect to negotiate these terms in year one. They are the outcome of relationship investment, not negotiation tactics.

When requesting term improvements, the most effective approach is to combine a direct request with concrete supporting evidence. A message like "we have completed five orders totaling USD 85,000 with on-time payment on every transaction — can we discuss adjusting to 30% deposit and 70% against B/L copy for future orders?" is far more effective than a general request for better terms. You are making the factory's risk assessment easy by presenting the evidence they need to justify the change internally.

Letter of Credit: How Documentary L/C Works

A letter of credit (L/C) is a conditional payment guarantee issued by a bank on behalf of a buyer, promising to pay the seller a specified sum upon presentation of specific documents that prove the seller has fulfilled their contractual obligations. In a documentary L/C transaction, the bank's commitment to pay is conditional on the seller presenting a compliant set of documents — not on whether the buyer is satisfied with the goods.

The parties in an L/C transaction are the buyer (applicant), the buyer's bank (issuing bank), the seller (beneficiary), and typically the seller's local bank (advising bank, which authenticates the credit, and negotiating bank, which advances funds against presented documents). The issuing bank's creditworthiness substitutes for the buyer's creditworthiness — the seller is relying on a bank guarantee, not a commercial promise.

The documents required under a standard documentary L/C for adult wellness products exported from China typically include: a commercial invoice in the specified format and currency; a full set of clean on-board ocean bills of lading or airway bills; a detailed packing list; a certificate of origin (usually from the China Council for the Promotion of International Trade or a local Chamber of Commerce); and often an inspection certificate from a third-party quality inspection body such as SGS, Bureau Veritas, or equivalent. Depending on the destination market and product category, additional documents may be required — CE declarations, health certificates, or regulatory approvals specific to the import country.

The seller presents these documents to the negotiating bank within the validity period specified in the L/C. The negotiating bank reviews the documents for discrepancies — any deviation from the exact specifications in the L/C, however minor. Common discrepancies include description of goods that does not exactly match the L/C text, bill of lading date outside the shipment period, quantity slight variations, or missing endorsements on documents. If discrepancies are found, the negotiating bank either returns the documents for correction (if time permits) or presents them to the issuing bank as a discrepant presentation, at which point the issuing bank may request the buyer's waiver of the discrepancy before authorizing payment. Discrepancy fees typically run USD 50 to USD 150 per discrepancy.

Chinese factories often add a premium of 1% to 3% to orders settled by L/C, for several reasons. First, the administrative burden is significant: the factory's documentation team must prepare a compliant set of documents within tight deadlines, and errors have direct financial consequences. Second, the factory typically draws on their bank credit line to finance production before the L/C is available for drawing, meaning they bear financing costs. Third, discrepancy risk means the factory may not receive payment as quickly as expected even after shipment. For buyers accustomed to the L/C as a buyer protection mechanism, it is worth understanding that from the factory's side, it represents additional cost and complexity rather than reduced risk.

When L/C Makes Sense for Adult Wellness Buyers

Despite the added cost and complexity, there are situations where a documentary L/C is the right tool for adult wellness B2B buyers. The first is large orders — typically above USD 50,000 — placed with a factory you have not worked with before and where the product involves significant custom development. In this scenario, the L/C protects you by conditioning payment on documented proof of shipment and conforming goods, and it protects the factory by providing a bank guarantee of payment rather than relying on your willingness to pay after delivery.

The second is market-specific practice. L/C is the standard or near-mandatory payment mechanism in many Middle Eastern markets, much of South Asia (particularly for Bangladesh, Pakistan, and Sri Lanka importers), and some African markets. If your business model involves distributing to buyers in these regions who pay you by L/C, structuring your own Chinese factory payment the same way creates a back-to-back L/C structure that is elegant from a cash flow perspective — you receive the L/C from your buyer and use it as collateral to open an L/C with your Chinese supplier.

The third is when you are building a new factory relationship and the order value is large enough that neither T/T nor trust alone feels sufficient. A well-structured L/C with clear document requirements, a third-party inspection certificate requirement, and appropriate shipment terms creates a framework where both parties have defined obligations and a neutral banking institution as referee. This can actually accelerate trust-building compared to a T/T transaction where disputes about quality or conformance have no structured resolution mechanism.

Each improvement is normally tied to evidence rather than to elapsed time: the drop from 30% to 20% follows a clean pre-shipment inspection, and net terms follow a track record of on-time payment across several cycles. Asking for net 30 on a first order signals that the buyer has not read the risk the factory is carrying. Ross, Westerfield and Jaffe frame trade credit as a supplier loan priced into the invoice, which is why open account terms usually arrive with a slightly higher unit price or a shorter quote validity [Ross et al., 2019]. The instrument comparison is in the T/T, L/C and trade finance guide; protecting against supplier failure in the second-sourcing guide; the delivery terms in the Incoterms guide.

Documentary Collection: D/P and D/A

Documentary collection sits between the informality of T/T and the bank guarantee structure of L/C. In a documentary collection, the seller's bank (remitting bank) presents shipping documents to the buyer's bank (collecting bank) with instructions to release them to the buyer only upon payment or acceptance of a draft.

Documents against payment (D/P) means the collecting bank releases the shipping documents — including the original bill of lading needed to claim the goods at destination — only after the buyer pays the collection amount. The buyer cannot take delivery of the goods without the bill of lading, so payment is effectively required before the goods can be accessed. This structure provides more security than simple T/T after shipment because the bank is holding the documents as leverage, though it does not involve a bank payment guarantee the way L/C does.

Documents against acceptance (D/A) means the collecting bank releases the shipping documents upon the buyer's acceptance of a time draft — essentially a promise to pay at a specified future date (e.g., 60 days after sight). The buyer gets the documents and can take delivery of the goods; payment is deferred. This structure is favorable for the buyer but carries significant risk for the factory, since the factory has shipped goods and has only the buyer's accepted draft — not a bank guarantee — as security. Chinese factories are generally reluctant to accept D/A terms except with buyers they know very well or where the transaction is backed by a payment guarantee from the buyer's bank.

Documentary collection is more commonly used in trade involving buyers in markets where L/C is burdensome to establish but where T/T after shipment is considered insufficient protection for the factory. It is less common in direct China-to-Western-buyer transactions, where T/T or L/C tend to dominate.

Open Account: Net 30, Net 60, Net 90

Open account (O/A) payment means the factory ships the goods, sends the invoice, and the buyer pays within the agreed credit period — net 30, net 60, or net 90 days from invoice date or shipment date. This is standard practice in many domestic Western supplier relationships and in some well-established international trade corridors. It is not standard practice for new relationships with Chinese adult wellness manufacturers.

The reason is straightforward: once goods are delivered and accepted in a foreign country, a Chinese factory has almost no practical recourse if the buyer delays payment or refuses to pay entirely. Legal enforcement of payment obligations across international jurisdictions is expensive, slow, and uncertain. Unlike a Western factory that might supply a retailer domestically with shared legal jurisdiction, the Chinese manufacturer dealing with a foreign buyer is genuinely exposed. The cost of chasing a USD 30,000 debt in a foreign legal system often exceeds the debt value itself.

Earning open account terms from a Chinese factory requires a combination of documented payment history, relationship investment, and often the involvement of credit insurance. The most direct path to O/A terms is: complete at least five to ten orders on T/T with a perfect payment record, establish a personal relationship with the factory's ownership or commercial leadership, and demonstrate consistent and growing purchase volume over at least 12 to 18 months.

Some Chinese factories offer O/A terms to established buyers backed by export credit insurance purchased through Sinosure (China Export and Credit Insurance Corporation, the state-backed export credit insurer) or through international commercial insurers such as Euler Hermes, Coface, or Atradius. Under these arrangements, the factory insures their receivable against buyer default with the insurer paying out a percentage (typically 80% to 90%) of the invoice value if the buyer fails to pay within the credit period. The insurance premium — usually 0.5% to 1.5% of insured turnover depending on buyer credit rating — may be borne by the factory, split between factory and buyer, or passed through to the buyer as a line item on the invoice. If a factory offers you O/A terms relatively early in your relationship, ask whether the terms are backed by credit insurance — if they are, it means the factory has evaluated your credit standing through the insurer and received coverage, which is a meaningful form of third-party validation.

Sample Fees and Tooling Deposits

Before the first production order, most OEM and ODM adult wellness projects involve sample development and potentially custom tooling. The payment structure for these pre-production phases is distinct from production order payment terms and is worth understanding clearly.

Sample fees for existing products — where the factory is simply producing a sample of a stock product to your private label specification — are typically modest (USD 50 to USD 300 per sample) and paid 100% upfront. This covers the factory's labor cost for sample preparation and any minor customization work. The fee is often credited against your first production order, though some factories do not offer this credit until you have confirmed your order.

Custom tooling — which includes injection molds for custom-shaped products, custom silicone molds, custom packaging dies, and custom electronic component housings — represents a far larger investment. Industrial-grade injection molds for adult wellness products typically cost USD 1,500 to USD 8,000 depending on complexity, size, and material requirements. Silicone molds are generally less expensive but still meaningful. The standard payment structure for tooling is 50% upfront upon confirmation of the tooling order and 50% upon sample approval. The 50% upfront covers the factory's material and initial labor costs; the 50% on sample approval ensures you do not pay the balance until the tooling has actually produced a sample that meets your specifications.

Negotiating tooling cost amortization into the first production order — or across the first several production orders — is a common and legitimate request. Under this structure, the tooling cost is spread across an agreed number of units or orders and added as a per-unit charge rather than billed as a lump sum. For example, if tooling costs USD 3,000 and your first production order is 1,000 units, the tooling is amortized at USD 3.00 per unit, effectively adding that amount to your unit cost for the first order (or split across multiple orders at lower per-unit increments). Factories are generally willing to discuss this because it reduces the buyer's upfront cash commitment and increases the likelihood that the buyer will proceed with the order. The trade-off is that the factory is financing the unpaid tooling cost across the production run, which may or may not matter to them depending on their working capital position.

The key negotiation point on tooling ownership is to ensure that the molds and tooling are formally documented as your property once fully paid. This matters because if you want to move production to a different factory in the future, you need to be able to take your tooling with you. Reputable factories will acknowledge tooling ownership in writing once payment is complete. Factories that resist this acknowledgment or claim ownership of tooling you paid for are raising a significant red flag about the long-term relationship.

Escrow Services and Platform-Based Payment Protection

For smaller orders, particularly those sourced through Alibaba or other B2B platforms, escrow-like payment protection mechanisms offer an intermediate layer of security that neither raw T/T nor formal L/C provides efficiently at small transaction sizes.

Alibaba Trade Assurance is the most widely used mechanism in this space. Under Trade Assurance, the buyer's payment is held by Alibaba rather than transferred directly to the factory. The factory ships the goods. If the goods arrive as described and the buyer confirms acceptance, Alibaba releases the payment to the factory. If there is a dispute, Alibaba provides a mediation process and, in qualifying cases, refund protection. Trade Assurance orders must be conducted through the supplier's Alibaba storefront and are subject to coverage caps and specific eligibility requirements. It is not a substitute for a full L/C in terms of legal enforceability, but it provides meaningful protection for orders in the USD 1,000 to USD 20,000 range where establishing a formal L/C would be disproportionately expensive.

PingPong, LianLian Pay, and similar cross-border payment platforms serve primarily as cost-efficient alternatives to traditional SWIFT transfers for T/T payments rather than as true escrow services. They offer faster settlement times (often same-day or next-day versus one to three days for SWIFT), lower transaction fees (typically 0.5% to 1% versus USD 25 to USD 50 fixed fees for SWIFT), and more transparent exchange rates. These platforms do not provide dispute protection or document-based payment conditioning. For established relationships where T/T is the agreed mechanism, they offer meaningful cost and efficiency advantages over traditional SWIFT transfers.

For custom ODM development projects at the smaller end of the scale, some buyers use milestone-based escrow arrangements facilitated by third-party escrow platforms like Escrow.com. These are relatively uncommon in China-to-international B2B trade because Chinese factories are not always willing to work through platforms unfamiliar to them, and the escrow platform's dispute resolution process may not be well understood by the factory's finance team. When proposing escrow arrangements to a Chinese factory, expect to spend time explaining the mechanism and addressing their concerns about payment timing and release conditions.

Currency: USD vs. RMB Invoicing

The large majority of China export invoicing for adult wellness products is conducted in US dollars. USD is the de facto currency of international trade, and Chinese factories have USD bank accounts for exactly this purpose. Pricing in USD eliminates exchange rate risk for the factory relative to Chinese buyers in other currencies and provides a common reference currency that both parties understand.

Renminbi (RMB, also called CNY) invoicing is occasionally offered or requested, particularly in the following scenarios. First, when the buyer is purchasing through a Hong Kong entity or has RMB accounts that make CNY settlement operationally convenient. Second, when the factory is located in a Cross-Border RMB settlement pilot zone and is actively promoting RMB internationalization as a commercial strategy. Third, when the factory is quoting in CNY to avoid exchange rate volatility in their own planning — if their costs are entirely CNY-denominated, a USD-invoiced transaction carries foreign exchange risk for them that a CNY transaction eliminates.

For buyers based outside China and Hong Kong, USD invoicing is almost always preferable. Your bank accounts are likely USD or your domestic currency, converting to USD is operationally simpler than converting to CNY for wire transfer purposes, and USD pricing provides a cleaner basis for cost comparison across multiple supplier quotes. If a factory insists on CNY pricing, ensure the proforma invoice includes a clear exchange rate and that both parties agree on what happens if the rate moves significantly between invoice issuance and payment date.

Exchange rate risk is a genuine consideration for large orders. An order priced at CNY 500,000 when the rate is 7.20 USD/CNY costs USD 69,444. If the CNY appreciates to 7.00 by payment date, the same amount in CNY costs USD 71,429 — a USD 1,985 increase. For buyers managing tight margins, it is worth either invoicing in USD from the outset or discussing a fixed exchange rate clause for the duration of the order cycle.

Wire Transfer Security and Business Email Compromise Fraud

Business email compromise (BEC) fraud is a significant and growing risk in China trade, and adult wellness buyers are not immune. BEC fraud targeting international wire transfers works as follows: a criminal intercepts or compromises the email communication between buyer and factory, monitors the transaction until a payment is expected, and then sends a spoofed email appearing to come from either the factory or the buyer's freight forwarder, providing fraudulent bank account details and requesting that the upcoming payment be redirected to the new account. The buyer transfers funds believing they are paying the factory; the funds go to a criminal-controlled account and are immediately moved and unrecoverable.

The bank account details you use for the first transfer to a factory should be verified through a channel entirely independent of email. This means calling the factory's official phone number — obtained from their website or business registration documents, not from their email signature — and verbally confirming the account name, bank name, and account number digit by digit. Some buyers request a bank letter on the factory's official letterhead confirming their account details. This verification step is not optional for first-time transfers; it is non-negotiable risk management.

Any mid-transaction email requesting a change of bank account details should be treated as a fraud attempt until proven otherwise by independent verification. Legitimate factories do not change their bank account details mid-transaction without an extraordinary business reason (bank insolvency, banking relationship change), and any such request should trigger an immediate phone call to a previously verified contact at the factory using contact details you have on file, not contact details provided in the suspicious email.

Additional security practices include confirming the exact transfer amount with your factory contact by phone or video call before initiating any transfer above a low threshold (many buyers use USD 5,000 as a trigger), double-checking that the bank account name matches the factory's registered company name before confirming the transfer, and using your bank's transaction confirmation feature if available to provide the factory with a transfer confirmation number that they can verify has been sent from your account.

Milestone Payment Structures for Large ODM Development Projects

For substantial custom ODM projects — a full custom product development involving bespoke industrial design, custom electronics, proprietary molds, and extensive testing — a single 30/70 T/T structure is often inadequate for both parties. The development cycle may span four to eight months and involve multiple decision points where the project could legitimately be paused, redirected, or cancelled. A milestone-based payment structure aligns financial commitments with project progress and protects both parties at each stage.

A four-stage milestone payment structure for a full custom adult wellness ODM project typically looks as follows.

Stage 1 — Concept Approval Payment (10% to 15% of total project cost). Paid upon signing the development agreement and approving the initial concept design, including 2D/3D renderings, feature specifications, and target cost sheet. This payment triggers detailed engineering design and begins the tooling quotation process. It demonstrates buyer commitment sufficient to justify the factory's initial engineering investment without requiring the buyer to commit substantial capital before seeing a concrete design.

Stage 2 — Sample Approval Payment (25% to 30% of total project cost). Paid upon approval of the first functional sample or upon reaching a pre-agreed sample milestone (for example, approved appearance sample even if functional testing is still in progress). This payment typically covers tooling costs and materials for the sample production phase. The factory has now invested substantially in mold fabrication and sample production; the buyer's Stage 2 payment covers these sunk costs and provides working capital for any sample revision cycles required.

Stage 3 — Pre-Production Confirmation Payment (25% of total project cost). Paid upon approval of the pre-production sample (golden sample) and confirmation of the production order. This is the effective commitment to full production; the factory uses this payment to procure production-quantity materials and components and to schedule production capacity. At this point, both parties have committed fully: the buyer has paid 60% to 70% of total project cost, and the factory has a complete, approved product ready for production.

Stage 4 — Balance Payment (30% to 40% of total project cost). Paid against copy of bill of lading or before shipment, depending on the relationship and the parties' agreement. This completes the financial transaction.

This structure requires more administrative coordination than a simple T/T — each milestone must be clearly defined, the criteria for milestone achievement must be documented in writing before the project begins, and both parties must have a shared understanding of what happens if a milestone is not achieved (for example, if the Stage 2 sample is not approved after two revision cycles). A professional OEM/ODM partner will welcome this structure because it signals that the buyer is serious, well-organized, and understands the development process — all of which reduce the factory's counterparty risk.

Negotiation Tactics: What Works and What Does Not

Negotiating payment terms with Chinese adult wellness factories is more effective when it is grounded in relationship logic rather than pure price-style bargaining. Factories respond well to buyers who demonstrate understanding of the factory's position, provide evidence of their own reliability, and make term improvement requests that are proportionate to the relationship stage.

The tactics that tend to work include: providing documented evidence of your payment history with the factory (purchase summaries, bank transfer records) when requesting term improvements; framing payment term discussions as mutual risk reduction rather than buyer demands; offering something in exchange for better terms — for example, committing to a minimum annual volume, agreeing to extend the production lead time (which helps the factory's planning), or prepaying a larger deposit in exchange for net terms on the balance; and making the request directly to the factory's commercial or finance leadership rather than through a sales representative who may not have authority to approve term changes.

The tactics that do not work — and that will damage your relationship if you try them — include threatening to switch suppliers as leverage for term improvements (factories can read when this threat is not credible), demanding O/A terms before you have earned them, and attempting to delay payment after goods are received as a way of creating de facto extended credit. That last tactic, sometimes called "payment stretching," is one of the fastest ways to destroy a Chinese factory relationship permanently. Chinese business culture places significant weight on payment integrity; a buyer who pays late without prior agreement is considered unreliable in a way that price disputes or quality arguments are not.

One genuinely useful negotiation lever that many buyers underutilize is the size of the deposit. Factories are often more flexible on the balance payment timing if you offer a larger deposit. A 40% deposit in exchange for 60% net 30 after bill of lading may be easier to agree to than a standard 30/70 variation, because the factory's materials and early-stage labor costs are fully covered by the larger deposit, reducing their financial exposure during production.

Red Flags in Factory Payment Requests

Not all payment requests from factories reflect standard practice, and some are warning signs of either fraud or serious business instability that should cause you to pause or exit the relationship.

A factory demanding 100% payment upfront before any production begins is unusual and concerning, particularly from a factory you have not worked with before. While 100% upfront is occasionally offered as a discount option (some factories will reduce the unit price slightly for full prepayment because it eliminates their working capital cost), it should never be the mandatory requirement unless the order is very small (below USD 500). A demand for 100% upfront from a new supplier for a substantial order is a significant red flag that deserves investigation.

Requests to pay through unconventional channels — personal bank accounts rather than the factory's corporate account, cryptocurrency, payment platforms with no dispute resolution, or accounts in a third country with no obvious business reason — are serious warning signs. Legitimate Chinese factories receive payment into their registered company bank accounts, which are typically at major Chinese banks (Industrial and Commercial Bank of China, Bank of China, China Construction Bank, Agricultural Bank of China) or at well-known commercial banks. Payment to a personal account, a Hong Kong company account with no clear relationship to the factory, or a cryptocurrency wallet should be refused.

A factory that is unable or unwilling to provide a formal proforma invoice on company letterhead with their company's registered business details, bank account information, and a person's name and contact number to verify is not operating at a professional level and should not receive your wire transfer until these basics are in place.

How Evokomoribi Structures Payment Terms with OEM/ODM Clients

Evokomoribi's standard payment structure for new OEM and ODM clients reflects both the industry default and our own approach to building sustainable buyer relationships. For first-time orders from new buyers, we operate on T/T 30/70 — 30% deposit upon proforma invoice confirmation, 70% balance before shipment or against scanned copy of bill of lading for buyers who have completed the pre-shipment quality confirmation step.

For custom tooling and mold development, our standard terms are 50% deposit upon tooling order confirmation and 50% upon sample approval, with tooling cost amortization available for buyers committing to minimum production volumes. We document tooling ownership explicitly in our development agreements, and buyers who have completed full tooling payment receive formal acknowledgment of ownership.

As buyer relationships develop — typically after three to five successful production orders with consistent on-time payment — we are willing to discuss term adjustments on a case-by-case basis. Common adjustments for established buyers include shifting the balance to net 30 after bill of lading date, reducing the deposit percentage for repeat standard products where the production risk is lower, and structuring milestone-based payments for new product development projects that span multiple months.

We accept payment in USD (preferred), EUR, and CNY. For buyers in markets where L/C is standard practice, we accommodate documentary L/C orders with the understanding that L/C terms must be agreed in advance and that our pricing for L/C orders reflects the additional documentation and financing cost involved. We work with Alibaba Trade Assurance for orders placed through our Alibaba storefront, and we can accommodate cross-border payment platforms such as PingPong for buyers who prefer lower-fee T/T alternatives.

Our finance and commercial teams are available to walk new buyers through our payment process in detail before any transaction is initiated. We provide verified bank account details through multiple channels and welcome the kind of due diligence calls that responsible buyers make before transferring funds to a new supplier. The buyers we build the longest and most productive relationships with are exactly the ones who ask the right questions at the beginning — about our payment processes, our business registration, our banking relationships, and the protections available to them as buyers. Those questions are not signs of distrust. They are signs of a professional counterparty who takes their sourcing seriously, and that is the kind of counterparty we want to work with for the long term.

Payment terms in China trade are not a fixed landscape. They are a negotiated, evolving structure that reflects the risk profile of the relationship at any given moment. Buyers who understand this — who approach payment terms as a dynamic variable tied to relationship investment and mutual risk management rather than as a static cost to be minimized — build better supplier relationships, get better terms over time, and avoid the costly disputes that arise when payment structure and relationship maturity are misaligned. That understanding is one of the most valuable assets a professional adult wellness B2B buyer can develop, and it starts with knowing exactly what each payment mechanism does, what risk it allocates to whom, and what it would take to move the structure in a direction that works better for both parties.
