Context
Accounting received around 400 PDF invoices a month in a shared inbox. Entry was manual, and mismatches only surfaced at reconciliation.
Workflow
- 01
Capture
The shared inbox is watched. Attachments are extracted and filed with the email they came from.
- 02
Extract
A vision model reads supplier, number, line items and VAT whatever the layout. Doubtful values are flagged rather than guessed.
- 03
Match
Checked against the purchase order. Past the variance threshold, the invoice goes to human review.
- 04
Post
The entry is created in the accounting tool with the PDF attached and a full audit trail.
