Supplier Due Diligence Checklist for B2B Buyers
Supplier verification should match the value and risk of the purchase. Higher-value, regulated or custom orders usually require deeper checks.
Business identity
- Confirm legal/business name, location and contact channels.
- Check whether the supplier's business scope matches the product offered.
- Verify documents through appropriate independent sources when needed.
Product and quality
- Confirm specifications and acceptance criteria in writing.
- Request samples or inspection where appropriate.
- Clarify corrective-action and replacement expectations.
Commercial and logistics
- Document price, currency, MOQ, payment terms, Incoterm and lead time.
- Understand who is responsible for freight, insurance, customs and taxes.
- Start with a controlled order when risk warrants it.
Frequently asked questions
Is marketplace verification enough for every order?
No. Marketplace signals help, but buyers remain responsible for appropriate due diligence.
Should I request samples?
For many new supplier relationships, samples or a controlled trial order can reduce specification and quality risk.
