Matching delivery notes and invoices automatically

The problem

Manually matching order, delivery note and invoice is slow and error-prone. Wrong quantities or prices slip through and cost real money.

The solution

The three documents are read automatically and matched line by line. Discrepancies (quantity, price, missing items) are highlighted — a human only looks at the differences.

How it works

1. OCR reads order, delivery note and invoice.
2. Line-by-line matching with clear tolerance rules.
3. Only discrepancies are surfaced for review.
4. An auditable trail for every decision.

What changes

Fewer errors slipping through, faster approvals, less dispute effort — with full traceability.

Honest take

Honestly, this is primarily a case for classic software: OCR plus clear rules. You don’t need a large language model for it — and shouldn’t use one when simple, verifiable logic is more reliable.
