Because it's a long tail of tiny obligations. Each raw material carries a certificate of analysis per lot, a specification, an SDS, allergen and origin declarations, and whatever a specific customer or market adds on top. Multiply by a few hundred materials and a few dozen suppliers, and it becomes a permanent part-time job that nobody was hired to do.

It's also invisible until it fails. Nobody notices the chasing. Everyone notices the audit finding, or the shipment held because a declaration expired.

It knows what's missing, because the material record knows what it should hold. It emails the right contact with a specific request rather than a generic one, follows up on a cadence you set, and stops when the document arrives. It then reads the document, extracts the values into the correct fields, and files the original against the material.

Where the extracted value disagrees with what's on record, it flags rather than overwrites. That flag is the useful output: a contradiction between a supplier's new certificate and your existing specification is exactly the thing that used to surface during an audit.

They get read too. A significant share of supplier documentation in this industry is a scanned PDF, sometimes a photograph of a printout, and any system that only handles clean digital files will leave the hardest cases with a person.

Confidence matters here: a low-confidence extraction should be flagged for review rather than filed silently. The right measure of these systems isn't extraction accuracy in the good cases, it's honest behaviour in the bad ones.
