This is what your customers see. The retailer set one link. The brand pushed a new batch. The page updated.
rd Labs serves the most recent lab results the brand published. It does not test products or validate results.
You uploaded one COA. The retailer set one link on their product page when they listed your product. That link points here, at raddadlabs.com/c/0099990000001.
When your next batch ships and you push the new COA, this same URL serves it automatically. The retailer’s product page doesn’t change. The link they set doesn’t change. The customer scanning the bottle on Tuesday sees the May 12 batch. The customer scanning the same bottle on Friday sees the June 1 batch.
You’re not Dropbox-blasting fifty retailers when a batch changes. You’re not fielding “can you send me the latest COA” emails. Every retailer carrying your barcode has the current results the moment you upload, and your customers verify a current COA every time, automatically.
