Signed purchase order
Signed purchase order — The document that turns a chat into an obligation. Once both parties sign, it is the only reliable reference when something goes sideways on delivery, quality, or price.
| Delivery date and deadline | the ship date and any penalty for missing it, tied to real calendar days |
|---|---|
| Quality bar | what counts as good — approved sample, accepted specs, tolerances — not just 'as usual' |
| Shipping terms | who pays which leg and where risk changes hands, stated via the agreed incoterm |
| Payment schedule | deposit, milestones, balance, method — matching how much risk each side carries |
| What-if clause | returns, replacements, refund paths if goods arrive outside what was agreed |
Convert the verbal deal into something enforceable
A conversation with a supplier is friendly and fast, but it is not a commitment until it is written and signed. The moment both names go on the purchase order is the moment the discussion becomes enforceable — and that document is then the only calm reference available when delivery slips, quality disappoints, or the price does not add up. Writing it down first is not mistrust; it is turning intent into something either side can point to.
The five seams where deals break silently
Delivery date and deadline, measured against real calendar days with a defined cost for missing it. Quality bar spelled out as an approved sample or accepted tolerance rather than the vague ‘usual standard’, which means nothing once you disagree about it. Shipping terms stating who pays each leg and where risk transfers, referenced through the specific incoterm so no one invents a boundary afterward. Payment schedule linking deposit, milestones, and balance to how much risk each side carries. And finally the what-if clause covering returns, replacements, or refund routes when goods arrive outside what was agreed — because every first-order buyer knows the unexpected is not a paranoia, it is a likely outcome.
Why detail here beats discount later
Signing a generous price with an unwritten quality bar costs more than any headline discount saves, because the disagreement lands after you have already paid. Putting these five things on the paper before the pen leaves your hand keeps the deal honest on both sides, and gives a first-time buyer something to lean on when the container arrives and the question is simply whether it matches what was promised.
Is the supplier's pro forma invoice enough as a contract?
It starts there but rarely finishes it. A pro forma lists price and quantity; it usually does not lock your quality bar or your refund path. Add those two before you consider it signed.
Should I agree to full payment upfront to get a lower price?
Not without trade protection behind it. The discount for paying early is real, but paying everything blind removes your leverage mid-flight. Tie the deposit to a clear gate and keep the balance releaseable against shipment.
