# How does AI read a supplier invoice and get it into bookkeeping?

It takes the invoice from email, a scan or a photo, reads the supplier, number, date, net and gross amounts, VAT rate and line items, then checks them against your order and delivery note. Matching invoices are prepared for booking; anything that disagrees goes to a person with the difference highlighted.

## Why this is more than text recognition

Character recognition tells you what letters are on the page. The useful part is understanding that this number is the net total and that one is a delivery note reference, on an invoice layout the system has never seen before. That is why a crumpled photo from a van still works, and why a new supplier needs no setup.

## The three-way check

The invoice is compared to what you ordered and what actually arrived. Quantity, unit price and agreed discount all have to line up. In practice this is where the money is: quiet price increases, double-billed deliveries and quantities that never arrived are found before payment, not at the year-end audit.

## What reaches a human

Anything where a field could not be read confidently, where the totals do not match, or where the supplier is new and not yet approved. The person sees the original document and the extracted fields side by side and confirms with one click.

## Asked next

**Does it work on handwritten delivery notes?**

Usually yes for printed forms with handwritten quantities. Fully handwritten documents are read with lower confidence and routed for confirmation rather than booked automatically.

**Can it handle invoices in German or English?**

Yes. Language does not change the fields, and mixed-language supplier documents are common in trade and manufacturing.
