Acceptance Criteria to Write Before Supplier Outreach: A Buyer-Owned Pass/Fail Outline
Acceptance criteria written before supplier outreach are a short, buyer-owned document for one product that states three things: what you will check, how you will check it, and what counts as pass or fail. It is a specification outline you control, not a legal standard, not a certificate, and not something a supplier issues to you. Write it before the first outreach message, because the questions you ask first decide what every quote you receive is actually offering.
Why the order matters
Three practical reasons, in the order they tend to bite.
Outreach without criteria produces quotes you cannot compare. Two suppliers may quote the same product name while assuming different materials, tolerances, packaging or documentation. Put your criteria into the request and the replies line up on the same scope.
Definitions are cheaper to agree before production than after. When a disagreement arrives later, the useful question is what the written criteria said at the time. A versioned draft gives you that reference; a conversation does not.
Uncertainty is better sent as questions than discovered in a shipment. Any line you cannot fill in is an open item, and open items are a legitimate part of the first message rather than a reason to delay it.
The seven fields
1. Item identity and revision. Name the product precisely, with the model or internal code you will use in correspondence, the scope of supply (what is included and what is explicitly excluded), and a version label so a later change is visible as a change.
2. Characteristics worth checking. List the aspects you will actually inspect: dimensions, material, function, surface or finish, packaging, labelling, and any documentation that must travel with the goods. If you would never check it, do not write it as a criterion.
3. A pass rule for each characteristic. For every line, write the target and either a tolerance or an observable condition that someone without prior knowledge of the product could apply. Words like good, clean or sturdy do not survive a disagreement; a stated condition does.
4. Inspection method and sample basis. Who inspects, where, with what equipment, over how many units, how those units are selected, and at what point in the process. At outreach stage this is your proposal rather than an agreed procedure; agreement on it is one of the things you are asking a supplier to confirm for this case.
5. What happens when something fails. Rework, sort, replace, hold for review, or reject — and who makes that call. Write your preferred handling now, then ask whether the supplier can operate that way.
6. Evidence and records. What will be kept as proof: photographs, measurement records, batch or lot identification, and how long you intend to keep them.
7. Open items. Everything you have not decided yet, written as questions. This is the part of the document that grows fastest during outreach and the part that prevents surprises later.
Blank worksheet
Copy this once per product and leave any cell you cannot answer unfilled; an empty cell becomes an open item rather than a guess.

Turning the worksheet into an outreach pack
Send four things together: the product definition you own (drawings, specifications, reference samples or a written description), the draft criteria with its version label, the list of open items as direct questions, and your proposed approach to inspection and records.
Ask each supplier to respond per line rather than in general terms — they can meet the line, meet it only with a stated change, or cannot meet it — and ask them to name which line they are answering. A general statement that they can meet your requirements is not the same as line-by-line confirmation, and no supplier statement about capability should be treated as established until it is confirmed for your specific case.
Keep ownership clear. You are not asking a supplier to write or certify your criteria. You are describing what you will accept and asking whether they can supply to it.
What your criteria are not
Not legal wording. Questions about contract terms, liability or enforcement belong with your own professional advisors; this document is a commercial specification aid, and nothing here is legal advice.
Not a certificate, and not proven by one. A screening result, a listing, or a supplier's quality-management claim is not product certification. ISO's own material presents ISO 9001 as a quality management standard, which is background context; it does not tell you whether a particular unit meets your pass lines, and nothing here should be read as a statement about any edition or clause.
Not settled by delivery terms. Terms of the Incoterms type allocate transport, cost and delivery responsibilities between the parties. They do not describe whether goods pass your criteria, and they do not set payment terms, which remain a separate commercial matter to be agreed for each case.
Not agreed just because it was quoted. A quotation responding to your criteria, and any price in it, are case-specific and still need confirmation before you rely on them.
Keep a decision log
Maintain one small table alongside the criteria so the current version is identifiable.
| Version | What changed | Who approved it internally | Still open |
|---|---|---|---|
Next action
Pick the product you are about to source and fill the worksheet as far as you can support. Keep the product definition and acceptance criteria together as one draft brief. The on-site Sourcing Desk worksheet formats that draft locally; it does not submit it. Project fit, supplier claims, quotations and next steps require a verified human channel and case-specific confirmation.
