BatchProof helps supplement, CBD, cosmetics, baby food, and other regulated brands publish batch test results and Certificates of Analysis (COAs), including heavy metals disclosure under California AB 899. Upload a COA PDF, link it to a product and batch, and customers verify results on your storefront by batch number or QR code. A dashboard tracks active, expiring, and expired batches; bulk CSV and PDF import migrate your archive. BatchProof displays your documents and never alters lab results.
