A supplier review starts with the purchase. The information needed for a recurring service differs from the information needed for a time-sensitive material order.
Write down the requirement and the questions that affect the decision. Then connect each question to the evidence available: supplier documents, buyer records, references, or appropriate public information.
Give each finding a source and a date
Record where the information came from, when it was reviewed, and what it establishes. Keep supplier statements identifiable as statements until the relevant check is completed.
A document can be outdated, unclear, or unrelated to the particular work. Note that gap and identify the person responsible for following up. Do not turn a missing answer into an assumed qualification.
The finished review should show what is known, what conflicts, and what remains open. Specialist questions still need the relevant adviser, and the buyer retains approval and selection authority.
Read about vendor due diligence or start a procurement review with the supplier, requirement, and documents you already have.
A simple evidence record
Use a record with the question, source, date reviewed, finding, remaining gap, and person responsible for follow-up. For an illustrative delivery review, the question might be whether the supplier can meet the required date. A written supplier statement records the claimed timing; an acknowledgement tied to the actual order provides different evidence.
Avoid treating an attractive website or a completed questionnaire as proof of every capability. Record the evidence that relates to this purchase. If two sources disagree, retain both and explain the conflict. The review should let the buyer see what still needs an answer before approval.
