What actually needs to be in writing before you pay anything?
The specific terms worth pinning down in a purchase order, and why a written agreement protects both sides, not just you.
A booth conversation and a handshake aren’t a contract — once real money and production are on the line, the specifics need to be written down and agreed by both sides, in enough detail that a disagreement later has something concrete to be resolved against.
What a purchase order actually needs to cover
- Exact product specification — materials, dimensions, and any customisation, precise enough that “roughly what we discussed” isn’t the standard either side is working from.
- Quantity and unit price, with the total value stated clearly.
- Payment terms — the deposit and balance split, method, and timing, matching whatever you agreed on the payment-safety page.
- Production and delivery timeline, with a specific date or date range, not a vague estimate.
- Quality standard and inspection terms — what happens if the goods don’t match the agreed specification, and who inspects before shipment.
- Shipping terms — covered in more detail on the FOB versus CIF page, since this determines who’s responsible for what once goods leave the factory.
Why this protects the supplier too, not just you
A clear written order protects a legitimate supplier from a buyer who later claims the goods don’t match an agreement that was never actually specified — precision cuts both ways. A supplier confident in their own process generally welcomes this rather than resisting it.
Reluctance to document terms is itself a signal
If a supplier pushes back on putting specifics in writing, or keeps steering the conversation back toward “trust” instead of a document, treat that reluctance as meaningful information. Routine international trade runs on written terms as a matter of course; avoiding them isn’t a sign of an easy, informal relationship, it’s a sign of one with no recourse if something goes wrong.
Matching the level of formality to the order
A small, low-risk reorder from an established relationship doesn’t need the same document weight as a large first order with a new supplier — use judgment, but err toward more documentation the larger and less familiar the deal is.
