Commercial terms in manufacturing are less negotiable than newcomers expect and more standardised than they fear. Most of what looks like a hard-nosed demand is simply convention, and most disputes come not from the terms themselves but from the two or three points that were never written down. In short, Payment Terms Contract Basics is the deciding factor for most buyers.
The usual shape of a first order
| Stage | Typical payment | What it is for |
|---|---|---|
| Order confirmation | 30% deposit | Material purchasing and slot booking |
| Production complete | 60–70% balance | Before shipment, often after inspection |
| Sample or tooling stage | Separately agreed | Moulds and engineering samples |
The deposit exists because the manufacturer is buying components and booking capacity on your behalf, often months ahead. Asking for it to be smaller is normal; asking for it to be zero is asking your supplier to finance your inventory.
For a first order with an unknown counterparty, a letter of credit or an escrow arrangement through a trade platform is a reasonable middle ground. Once you have history, the terms loosen by themselves — a relationship with ten orders behind it is a different negotiation from the first.
Incoterms: the one term that moves the most money
EXW, FOB, CIF, DDP — these define who pays and who carries risk at each point of the journey, and they are the terms most often accepted without being understood. EXW means you collect from the factory gate and own the risk from that moment. FOB means the supplier delivers to the port and loads it; you own the sea leg. CIF adds insurance and freight to the destination port. DDP means delivered, duty paid, at your door — the most convenient and the most expensive, and the one where the supplier is pricing risks they cannot fully control.
FOB is the common default for a reason: it gives you control of the freight and insurance, and it keeps the supplier’s responsibility clearly bounded. If you are new to importing, the practical advice is not to choose DDP for the convenience — it is to work with a freight forwarder who explains the landed cost, because duty and VAT are where a good-looking unit price becomes an uncompetitive one.
What to write down, because it is otherwise assumed
- Lead time definition — from deposit, from approved sample, or from tooling completion. These differ by weeks.
- What happens on delay — a stated remedy, or at least a notification obligation.
- Specification baseline — the approved sample, identified by date and version, is the reference for acceptance.
- Warranty and defect rate — what percentage is tolerated, how claims are made, and who pays freight on returns.
- Component substitution — whether a specified chip or sensor may be swapped for an equivalent without your approval. Ask for “no substitution without written approval”.
- Tooling ownership — covered separately in the tooling and IP guide, and it belongs in the commercial agreement too.
That last-but-one item is worth emphasising. An “equivalent” component is how a product’s behaviour changes silently between batches — a different sensor with the same datasheet headline can behave differently in the field, and you find out from customers.
Currency and price validity
Export prices are usually quoted in US dollars with a validity window, commonly 30 days, because component costs and exchange rates move. If your order spans a long development cycle, ask what happens to the unit price if a key component rises sharply — a clause that shares the risk is more useful than a fixed price the supplier cannot honour. Long-term agreements handle this with a review mechanism rather than a fixed number.
Ordering volume: the discipline that protects you
The strongest commercial position for a first programme is a small first order with a stated intention to reorder. It tests the product, the packaging and the demand before you own six months of inventory, and it is the logic behind the low-MOQ route and the volume guidance in the MOQ guide. What to avoid is the opposite: a maximum order placed to hit a price break, on a product whose first batch has never been in a customer’s hands.
Frequently Asked Questions
Is a 30% deposit normal?
Yes. Lower is negotiable with history; zero is not realistic for a custom product.
FOB or DDP?
FOB for control and transparency if you have a forwarder; DDP only if you genuinely cannot manage import, and price the convenience.
Can the price change after I order?
Not within the validity window. Ask what happens after it, and how component cost spikes are handled.
Should I use a letter of credit?
For a large first order with a new supplier, it is a sensible protection. For small orders the fees outweigh the benefit.
The questions buyers most often ask at this stage are collected in the wholesale FAQ, and the cash-flow picture across a programme is in the development cost breakdown. That is why Payment Terms Contract Basics keeps gaining attention in this category.
