Automated invoice capture engine
Invoices arrive by email and are filed on their own: fields are extracted from the PDF, checked against tax rules and recorded, with no typing.

The problem
Someone forwarded the invoices and someone else typed them in, one by one, with typos that only surfaced later in the accounts.
What I built
A language model reads the attached PDF and returns company, invoice number, date, tax authorisation code, VAT, gross income withholding, other withholdings, freight costs, currency and exchange rate. Tax rules fill in what the document does not carry and flag anything doubtful for review.
What changed
Manual invoice entry disappeared from the process. It only asks for a human when a validation does not add up.
