Show customers the lab results behind every batch you sell.
COA Vault is the certificate-of-analysis app for Shopify supplement, hemp, and cosmetics brands. Upload your COAs, link lot numbers, print QR codes — customers scan or search and see the right document for their exact batch.
14-day free trial. $14.99/month after — unlimited COAs and batches. Most stores are set up in about 10 minutes.
Every certificate, filed and findable
Drop in your lab's PDFs — several at once — and link each one to the batch numbers it covers. Batches that don't exist yet are created automatically. Search by title, lab, lot number, or product, and see instantly which batches are missing certificates before customers do.
QR codes that outlive your website
Labels are printed in ink and live for years. COA Vault codes don't freeze your current setup into the label — they resolve to whatever your certificate page is today. And if you have codes on packaging already, you don't reprint anything: here's the migration plan.
Lab results right on the product page
Drop the lookup block onto any product page and it automatically shows that product's latest certificates — shoppers see the proof before they buy, no lot number needed. Customers holding the product scan the label or type their batch number and get their exact batch. Lookups are anonymous: no accounts, no cookies, no personal data.
Transparency is becoming law, not a nice-to-have.
New York already requires QR codes linking to lab results on hemp product labels. Cosmetics regulation (MoCRA) is pushing the same direction for beauty. The brands that treat batch-level transparency as a feature — not a chore — are the ones customers come back to, and the ones regulators never have to call.
A note from the builder: Lot Foundry is a small Texas shop, not a venture-funded suite. COA Vault does one job well, costs $14.99, and doesn't touch your customers' data. I read every support email myself, usually same day. — Brian, brian@lotfoundry.com
