I. Industry Benchmarks
Industry benchmarks for down payments. According to industry practice, the down payment for non-standard assembly lines is typically around 30% of the total contract value.
Disclosures in annual reports from listed companies in the equipment sector indicate that downstream customers make installment payments based on specific milestones—such as contract signing, factory acceptance of the complete line, mass production acceptance, and the conclusion of the warranty period—with a down payment of approximately 30% usually made upon signing. Standard contract templates for non-standard equipment often stipulate a 30% payment within three days of signing, 40% prior to delivery upon completion of production, 20% within ten days of passing acceptance testing, and a final 10% retained as a warranty bond. In the custom equipment industry, the initial deposit generally ranges from 30% to 50%;
this down payment marks a critical milestone for initiating the order, allowing manufacturers to procure raw materials and cover upfront costs while also ensuring the customer does not cancel the order at the last minute.
II. Three Payment Structures
Three common payment structures.
Industry practices generally feature three mainstream payment structures: 30/70 (30% deposit, 70% balance before shipment)—the most common method, suitable for standard machines with short lead times (2–4 weeks); 30/40/30 (30% deposit, 40% upon completion of production/FAT acceptance, 30% before shipment)—suitable for customized machines and large-scale projects; and the 3-4-2-5 model (30% prepayment for scheduling and material preparation, 40% before shipment, 25% balance after on-site installation, commissioning, and acceptance, and 5% retention money settled after the warranty period expires). Another variation is 30/60/10 (30% deposit, 60% before shipment, 10% upon acceptance and delivery), often used for non-standard assembly lines with customization requirements; for these, the 30/40/30 or 3-4-2-5 models are preferred.
III.
Factors Determining the Amount
What determines the prepayment amount?
Industry analysis shows that the prepayment ratio is influenced by four factors: Order Value—suppliers may lower the requirement to 30% for large orders (over one million yuan) to ease the client’s financial pressure, whereas small orders might require 50%; Partnership History—long-term clients can negotiate terms like 50/50 or even 100% payment after acceptance; Degree of Customization—modifications to standard components require lower prepayments, while entirely new custom developments require higher ones; and Supplier Qualifications—well-known major manufacturers may accept 30%, while small and medium-sized enterprises (SMEs) might charge 40% to 50% to mitigate risk. Ultimately, the prepayment amount is not fixed;
it represents a trade-off between trust and risk—negotiations with new suppliers typically start at a 30% prepayment.
IV. Deposit vs. Prepayment
The difference between a prepayment and a deposit.
In contractual practice, it is crucial to distinguish between two concepts: a **deposit** (or earnest money)—which serves as a guarantee, is generally non-refundable, and triggers penalty clauses upon breach (the payer forfeits the deposit if they breach, while the recipient must refund double the amount if they breach)—and an **advance payment**—which constitutes partial performance of the contract and is refundable if the contract is not performed or is terminated. Regarding standard contract templates, deposits for customized engineering projects should not exceed 20% of the contract price. Regarding **bank guarantees**, when the advance payment ratio is high (e.g., 40%), the supplier must provide a bank guarantee for the advance payment equal to that amount, with payment due from the client within 15 days of receiving the guarantee;
contracts should clearly specify whether a payment is an advance or a deposit and the conditions for its refund to avoid disputes.
V. Risk Control
Risk control regarding payment milestones.
Industry best practices for secure advance payments include: **linking payments to milestones**—payments are tied to six specific stages (design freeze, material delivery to site, Factory Acceptance Test/FAT, shipment, on-site acceptance, and the warranty period), ensuring each payment corresponds to a verifiable milestone; **managing the final payment ratio**—retaining 5% to 10% of the contract value as a warranty bond until the warranty period (12 to 24 months) expires; **deeming acceptance upon delay**—treating a failure by the client to conduct acceptance inspections on time as deemed acceptance, thereby preventing payment delays; **using bank guarantees as a safeguard**—requiring bank guarantees for large advance payments; and **remaining vigilant against scams**—demands for 100% advance payment, refusal to negotiate, and high-pressure urgency are typical signs of payment fraud; the industry standard for new suppliers is typically a 30% deposit followed by 70% payment prior to shipment—full advance payment should never be made.
Conclusion
What is the typical down payment for a non-standard assembly line? The conclusion is: “Start at 30%, tie payments to milestones, and never pay the full amount upfront.” Key aspects include: Benchmark—industry standard is around 30%; Structures—30/70 (standard machines), 30/40/30 (custom machines), 3-4-2-5 (large projects: 30% down, 40% upon delivery, 25% final payment, 5% retention/warranty bond), or 30/60/10; Influencing Factors—order value (30% for large orders, 50% for small ones), partnership history (50/50 for established clients), degree of customization, and supplier qualifications; Distinctions—”earnest money” (deposit) acts as a guarantee and is non-refundable (capped at 20%), whereas a “down payment” is refundable (large down payments should be backed by a bank guarantee); Risk Control—tie payments to six milestones, retain 5%–10% as a warranty bond for 12–24 months, treat overdue acceptance as automatic approval, and guard against “100% upfront payment” scams.
Industry convention holds that the down payment secures the supplier’s commitment to start work, while the final payment preserves the buyer’s leverage regarding acceptance;
ultimately, clearly defining acceptance criteria for each milestone is far more important than simply negotiating the payment ratios.
