Who this helps
Private-label sellers using supplier declarations, factory letters, or relationship explanations with invoices and test reports.
Supply chain pre-review
Check private-label supplier letters before relying on them.
Review private-label supplier letters for seller identity, factory relationship, product scope, brand ownership, and supporting invoice references.
What it checks

- Supplier or factory relationship
- Product and model scope
- Invoice and report references
How to use it before submission

Can SellerCheckAI create the supplier letter?
No. It can help review consistency of an authentic source letter; it does not fabricate documents.
What makes these letters risky?
Vague product scope, mismatched company names, missing dates, and unsupported authorization claims can create review risk.
