Supplier Documentation Checklist

How to request, track, and organize supplier certificates, test reports, invoices, and authorization letters for marketplace audits and compliance reviews.

Who this is for

  • Importers managing multiple factories or SKUs
  • Sellers preparing for authenticity, invoice, or compliance audits
  • Operations teams building documentation folders for new product lines

What this guide covers

  • Core supplier documents: invoices, certificates, test reports, authorization letters
  • Request email templates and tracking sheets for missing files
  • SKU-level indexing so documents match the correct listing
  • Expiry and version control for certificates over time
  • Export package structure before submitting to a marketplace or reviewer

Common mistakes

  • Requesting documents verbally without a written checklist for the supplier
  • Filing PDFs by supplier name only — not by SKU, batch, or ASIN
  • Using expired certificates after a product or factory change
  • Submitting invoices that do not clearly link to the product under review
  • Waiting until an audit notice to start collecting basic supplier records

Required documents or evidence

  • Commercial invoices linking supplier, quantity, and SKU
  • Test reports or certificates of conformity (when applicable)
  • Authorization or brand license letters for distributed products
  • Factory contact log and document request history
  • SKU-level index of received vs. missing files
