A payment milestone is not simply a percentage. It is the point at which you lose or retain leverage over the order.

When a supplier asks for a deposit, I ask:

  • What will exist after this payment?
  • What evidence will I receive?
  • What can I still stop or change?
  • How much money is exposed if the next step fails?

The right answer depends on the product, order value, relationship, payment method, contract, delivery term and recoverability. There is no universal “safe” deposit percentage.

This is a commercial-risk control guide. It is not legal advice on contracts, escrow, payment instruments or remedies.

1. The short answer

Use a payment-exposure map before approval. For each milestone, record:

  1. the amount and percentage;
  2. the evidence or production event that must happen first;
  3. the control you retain after paying;
  4. the failure mode you are accepting; and
  5. who approves the release.

If a supplier wants payment before the product, specification, beneficiary, sample or inspection basis is clear, I would pause the order. A lower percentage does not fix an unclear transaction.

2. What the main payment milestones mean

Deposit or pre-production payment

A deposit can fund materials, tooling, production slots or supplier working capital. It also moves risk to the buyer before the finished goods exist.

Before paying, I want the legal seller, product version, quantity, price, delivery terms, payment beneficiary and next production event written down. If tooling or setup is included, state who owns it, what is being made and how it will be identified.

Progress payment

A progress payment should correspond to an observable production state or a defined deliverable. “Production started” is too vague unless both sides agree how it will be evidenced.

Ask whether the milestone means materials purchased, components received, a defined percentage of units assembled, a production photograph, a sample approval or an inspection report. The more money exposed, the more precise the evidence should be.

Balance payment

The balance is often where the buyer still has the most practical leverage before shipment. That does not mean withholding payment is always lawful or commercially wise. It means the release condition should be explicit.

Tie the balance to the agreed inspection event, document pack and shipment information. State what happens if the inspection finds an issue, and get contract advice before relying on a remedy or withholding right.

Credit or open-account terms

Credit terms can reduce the buyer's pre-shipment exposure, but they are not automatically available or cheaper. The supplier may price the risk into the offer, require a credit check or limit the first order.

Compare the whole offer. A supplier with credit may still have a higher landed cost or less suitable product. A deposit-based supplier may be acceptable for a small trial when the identity, sample and controls are strong.

3. Build the payment-exposure map

Use one row per release. Here is an illustrative first-order example for a £6,000 production run. The percentages are not market standards and are not a recommendation.

Milestone: Illustrative amount: Evidence required before release: Control retained after payment: Failure to plan for
MilestoneIllustrative amountEvidence required before releaseControl retained after paymentFailure to plan for
Deposit£1,800, 30%Signed quote, approved specification, beneficiary check and production planAbility to request agreed updates and sample or process evidenceSupplier does not start, changes inputs or cannot explain delay
Progress release£2,400, 40%Defined production evidence, component confirmation and open-issue logLimited leverage over the final balance and inspectionGoods are partly complete or differ from the approved version
Balance before shipment£1,800, 30%Inspection report, defect resolution, final quantity and shipping documentsShipment release and document collectionPayment is made before unresolved defects are addressed

The useful question is not whether 30% is reasonable in the abstract. It is whether the £1,800 deposit buys a defined next step and whether the remaining £4,200 is still connected to evidence you can verify.

Add these fields to your own sheet:

Failure modeWhat could go wrong after this release

4. Tie payment to evidence, not reassurance

I would not use “the supplier said it is ready” as a payment trigger. Use a specific record.

Weak trigger: Stronger trigger to define
Weak triggerStronger trigger to define
Production has startedMaterials and approved specification are recorded, with a dated production plan
Goods are almost readyDefined quantity and product version are complete, with dated evidence and open defects listed
Inspection passedReport identifies the shipment, sample method, findings and unresolved items
Ready to shipQuantity, packaging, documents, release decision and named carrier handoff are recorded

The stronger trigger still needs judgement. A photograph is evidence of a photograph, not proof that every unit is complete. An inspection is evidence within its scope and sample. State the limitation beside the trigger.

5. Use inspection to create useful leverage

Inspection has value when it happens early enough to change the outcome and when the acceptance criteria were agreed in advance.

Before commissioning or accepting an inspection, define:

  • product version and reference sample;
  • quantity and production stage;
  • characteristics to inspect;
  • sampling method and measurement method;
  • packaging, labelling and document checks;
  • defect categories and escalation threshold;
  • who receives the report; and
  • what payment or release decision follows each result.

Do not describe an inspection as “quality checked” without stating what was checked. The report should identify the order, date, site, sample and limitations.

An inspection creates commercial information. It does not automatically create a legal right to reject, a guarantee of all units or a promise that a bank will reverse a payment. Have the governing contract and remedy position reviewed where the order is material.

6. Safer alternatives to a blunt deposit negotiation

If a supplier will not change the headline percentage, change the structure you are buying.

Reduce the first order

A smaller trial can reduce total exposure while the supplier relationship and product are tested. Compare the resulting unit price, setup charges and freight before deciding.

Stage the production

Agree a smaller release, then another release after a defined inspection or production event. Make sure the supplier can operationally separate the batches and that the staged order does not create hidden cost or quality problems.

Clarify tooling and setup charges

Separate one-time tooling, artwork, mould or setup payments from goods payments. Identify the asset, owner, revision and what happens if production stops.

Use a protected payment method where suitable

Payment services and bank products have their own conditions, exclusions and dispute processes. Treat any protection as a defined set of terms, not a general guarantee. Read the provider's current rules and obtain advice for a material transaction.

Trade forecast visibility for flexibility

A supplier may accept a smaller immediate order if you provide a realistic forecast or staged call-off plan. Do not give a forecast you cannot support, and do not let a forecast create an obligation you have not reviewed.

Change the product or packaging

Sometimes the MOQ or deposit is driven by a custom finish, printed packaging or tooling. A standard option may reduce setup exposure. Record the commercial and product trade-off rather than calling it a free saving.

7. When reasonable terms still do not fit your risk

A supplier can offer ordinary terms that are wrong for your situation.

I would pause when:

  • the deposit is large relative to the cash you can afford to lose;
  • the product is regulated, bespoke or difficult to replace;
  • the supplier's legal identity or beneficiary is unresolved;
  • the sample is not approved against a written specification;
  • the inspection trigger is too late to influence shipment;
  • the supplier refuses to define what happens after a failed inspection; or
  • the Incoterm, shipping control and payment release do not line up.

Do not solve a risk mismatch by negotiating a smaller number without fixing the trigger. A £500 payment can still be unsafe if the seller and beneficiary are unclear.

8. Check payment terms against the Incoterm

An Incoterm allocates defined delivery tasks, costs and risks between seller and buyer. The ICC Incoterms rules explain the importance of using the rule with the named place and of understanding the handover point.

Payment timing is a separate commercial control. Make sure the quote does not say “balance on shipment” while your practical control depends on an inspection after the shipment has already left. Make the sequence explicit:

  1. production complete;
  2. inspection performed;
  3. defects resolved or decision recorded;
  4. balance released;
  5. shipping documents and handoff confirmed.

The right sequence depends on the contract, route, payment method and supplier. Do not present it as a universal rule.

9. Questions to put in writing

Before paying a deposit, ask:

  • Which legal entity is contracting and receiving payment?
  • What exact product, packaging and specification version is covered?
  • What does the deposit fund?
  • What event starts the production lead time?
  • What evidence will be provided before each later milestone?
  • Who can approve a change to product, site, beneficiary or delivery date?
  • What inspection is included, who appoints it and what does it cover?
  • What happens when the inspection finds an issue?
  • When are the balance and shipping documents due?
  • Which costs, taxes, freight and insurance are excluded from the quote?

Keep the answers with the quotation and purchase order. If the answer changes by phone, ask for the written version before releasing money.

10. What to do next

Use the supplier payment-scam control guide for new or changed bank instructions. Reconcile the seller and beneficiary with the identity and VAT guide, then compare the full offer in the quotation comparison article.

For a first production run, connect the payment map to the supplier audit checklist, the product specification and the first production-order handoff.

This is general commercial-risk guidance, not legal, banking, financial or contract advice. Payment protection, inspection rights and remedies depend on the actual terms and governing jurisdiction.

11. Frequently asked questions

What is a normal supplier deposit?

There is no universal normal percentage that makes a transaction safe. Assess the total exposure, product, supplier history, evidence, inspection timing and ability to recover or replace the goods.

Should I pay the balance before inspection?

Only if the agreed commercial structure makes that acceptable and the risks are understood. If inspection is meant to inform the balance decision, schedule it early enough and define the evidence and response before paying.

Does escrow guarantee my money?

No. Escrow and payment services have specific terms, release conditions, fees and exclusions. Review the actual provider agreement and obtain advice for a material order.

Can I refuse a progress payment?

That depends on the contract and applicable law. From an operational perspective, identify the evidence that triggers the payment and raise an unresolved gap before the due date. Do not assume a general checklist creates a legal withholding right.

What is the best payment structure for a first order?

The one that matches the supplier, product, order value, evidence and inspection route. A smaller trial, staged release or clear pre-shipment control may reduce exposure, but each can change price, lead time and supplier willingness.
