Supplier Due Diligence Checklist for B2B Buyers

Updated 24 Aug 2026· 9 min read· Buyers & sourcing

Supplier verification should match the value and risk of the purchase. Higher-value, regulated or custom orders usually require deeper checks.

01

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.
02

Product and quality

  • Confirm specifications and acceptance criteria in writing.
  • Request samples or inspection where appropriate.
  • Clarify corrective-action and replacement expectations.
03

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.
