Two suppliers can both quote “30% deposit, 70% balance” while offering very different risk positions.
One may require the balance when production is reported complete, before an independent inspection. Another may make payment conditional on a passed inspection against an agreed specification. The percentages are identical. The evidence, remaining leverage and consequences of failure are not.
Payment terms should therefore be read as a sequence of commitments: what money is released, what it enables, what evidence must exist first and what happens if the milestone is not achieved.
Separate five issues that buyers often combine
A payment discussion can involve five different subjects:
- Payment schedule: the amount or percentage due at each stage.
- Payment trigger: the event and evidence that make an instalment eligible for release.
- Payment method: bank transfer, platform payment, card, letter of credit or another agreed route.
- Delivery and risk allocation: addressed separately through the sales terms and selected Incoterms® rule.
- Remedies: what the parties will do after delay, non-conformity, failed inspection or non-delivery.
Changing one does not automatically change the others. Incoterms® rules do not set payment terms or determine the product specification. A payment platform does not correct an incomplete inspection trigger. A favourable percentage split does not help if the buyer must pay the balance before meaningful evidence exists.
Map the money against the order timeline
Before negotiating percentages, map the major production events:
- specification and commercial scope frozen;
- tooling or setup authorised;
- materials committed;
- sample or production-intent reference approved;
- production started;
- defined progress milestone achieved;
- production completed;
- independent inspection completed;
- corrective work and reinspection completed where required;
- shipping documents verified; and
- goods released or shipped.
Not every order needs a payment at every event. The map exposes which stage the supplier is being funded to reach and how much buyer money will be exposed before the next independent check.
The deposit: what is the buyer funding?
A deposit may fund materials, components, production allocation, tooling work or supplier commitment. Before it is paid, the buyer should already have resolved the matters that would be expensive to change later:
- contracting supplier and approved payment recipient;
- controlled product specification and exceptions;
- quantity by SKU and variant;
- tooling, samples, packaging, testing and inspection scope;
- unit price, currency and one-time costs;
- delivery basis and precise named place;
- production and shipment timetable; and
- the next payment milestone.
Ask what the deposit authorises. “Start order” is vague. It should be clear whether the supplier may purchase non-cancellable material, complete tooling, schedule the line or begin bulk production.
The deposit size cannot be judged without that scope. A product requiring dedicated material and custom tooling exposes the supplier differently from a stock product packed in a standard carton. No single percentage is defensible for every order.
Progress payments need observable progress
An intermediate payment can be reasonable when it corresponds to a valuable, verifiable stage. It becomes risky when the trigger is an internal activity the buyer cannot distinguish from a promise.
Good milestone drafting identifies:
- the required deliverable or production state;
- the specification or drawing revision;
- the quantity or population covered;
- who verifies completion;
- the evidence format;
- pass, conditional-pass and fail criteria;
- the correction and recheck path; and
- the amount released after acceptance.
For tooling, evidence might include the agreed design review, uniquely identified tool, dimensional results and approved initial parts. For production, it might be a defined quantity completed through the intended process plus an agreed inspection result. Photographs can support a record, but they should not be treated as proof of hidden materials, internal construction, total quantity or process stability.
The balance: completion is not acceptance
“Balance when goods are finished” leaves important questions unanswered:
- Who determines that production is complete?
- Does complete mean manufactured, packed or ready for collection?
- Has the buyer or inspector been given access?
- Which inspection plan and defect criteria apply?
- What happens after a failed inspection?
- Must rework and reinspection occur before release?
- Which documents must be checked?
- Does paying the balance remove practical leverage needed to correct the order?
The buyer should not invent inspection conditions after production. The purchase record must establish the inspection right, timing, access, criteria, reporting route and payment consequence before the deposit.
One conforming sample does not establish that the whole lot conforms. Likewise, a passed pre-shipment inspection is evidence under a defined sampling and acceptance plan; it is not a guarantee that every unit is perfect or that all compliance obligations have been satisfied.
Compare payment structures by residual exposure
| Proposed trigger | Evidence available | Exposure after payment | Control response |
|---|---|---|---|
| Order confirmation | Accepted specification, PI and order record | Supplier has buyer funds before production evidence | Limit authority to defined setup/material commitments |
| Material purchase | Purchase or receipt evidence for identified inputs | Material identity, custody and usability may remain uncertain | Define input, quantity, ownership and inspection rights |
| Production progress | Identified units or production records | Completion and conformity remain open | Use a measurable stage and independent evidence where justified |
| Production completion | Supplier completion notice | Packed quantity and conformity may be unverified | Do not equate self-reported completion with acceptance |
| Passed inspection | Report against agreed criteria and product revision | Sampling limits, shipping and document risk remain | Resolve failures and verify release documents before payment |
| Shipping document | Agreed authentic document set | Quality disputes and transport events may remain | Define exact document and verification process in advance |
| Credit after delivery | Receipt and agreed credit period | Supplier carries more buyer credit risk | Expect due diligence, limits or pricing effects |
This table is a risk-reading tool, not a preferred universal sequence. Product, supplier relationship, order value, tooling, financing and bargaining position all affect the workable arrangement.
Define what a passed inspection means
“Balance after inspection” sounds controlled but is incomplete unless the following are agreed:
- product, specification and approved sample revision;
- inspection stage and location;
- inspector and booking responsibility;
- quantity available and sampling method;
- critical, major and minor defect definitions;
- functional, dimensional, packaging and quantity checks;
- treatment of pending laboratory tests;
- pass, fail and hold rules;
- rework, sorting, replacement and reinspection process; and
- person authorised to release payment.
Do not use “approved with conditions” for unresolved safety, compliance or critical-function failures. Those issues require a hold until the required evidence exists.
Record the failed-milestone path before failure
A milestone term is weak if it says only when the supplier is paid. It should also address what happens when the evidence is missing or the result fails.
The commercial record should cover, with appropriate legal review where needed:
- notice and response times;
- investigation and corrective-action expectations proportionate to the failure;
- rework, replacement or revised-delivery proposal;
- responsibility for reinspection and additional handling;
- whether payment remains held, is adjusted or requires a documented variation;
- termination or escalation route; and
- treatment of materials, tooling and partially completed goods.
Do not assume a payment hold creates every desired legal remedy. International contracts can involve foreign law, and enforceability should be reviewed by an appropriately qualified adviser.
Payment method is a separate risk decision
Buyers frequently ask whether bank transfer, card, marketplace payment or another method is “safe”. The useful questions are more specific:
- Is the recipient the authorised party recorded for the transaction?
- Does the payment reference identify the order and instalment?
- What current platform, bank or financial-product terms apply?
- What evidence and deadlines would be required for any dispute process?
- Does the payment route match the written order record?
- Has any late change to recipient or account details been independently checked through an established contact channel?
Protections change by provider, country, transaction and method. Do not rely on forum claims about guaranteed refunds or chargeback periods. Obtain current terms directly from the provider and professional advice where the exposure justifies it.
Use a milestone release record
For each instalment, record:
| Field | Entry |
|---|---|
| Order and payment reference | PO, PI or contract identifier and instalment number |
| Amount and currency | Exact amount, not percentage alone |
| Milestone | Observable state or deliverable |
| Required evidence | Report, identified sample, document or verified record |
| Acceptance basis | Specification, drawing, sample and criteria revisions |
| Result | Pass, fail, hold or approved variation |
| Open issues | Conditions that remain unresolved |
| Release authority | Named buyer representative and decision date |
This record does not replace the purchase contract or financial controls. It prevents a chat message from becoming the only evidence that a substantial payment was approved.
Questions to settle before accepting supplier payment terms
- [ ] What does each payment authorise the supplier to do?
- [ ] What buyer money is at risk after each instalment?
- [ ] Which evidence must exist before release?
- [ ] Who verifies the evidence and who authorises payment?
- [ ] What happens if the milestone is late, incomplete or failed?
- [ ] Are product, tooling, inspection, shipping and document requirements already written?
- [ ] Are payment schedule, method, Incoterms rule, title and remedies kept distinct?
- [ ] Does the PI reproduce the accepted terms accurately?
- [ ] Has any account or recipient change been independently checked?
- [ ] Would the buyer still have a practical correction path after paying the balance?
The best terms make progress visible
Payment terms cannot eliminate sourcing risk. They can prevent the buyer from funding the next stage before the previous one has produced the agreed evidence.
That requires more than negotiating a favourable-looking percentage. Define what the deposit funds, what progress can be observed, what an inspection result means and what happens when the order does not reach the milestone.
