The problem it solves

Suppliers send electronic invoices as PDF or XML attachments, and copying the invoice number, amounts, and dates into your records by hand is tedious and easy to get wrong. You need an accurate, organized record without opening every single attachment.

Who it fits

Small businesses or bookkeepers handling a steady stream of supplier e-invoices from European suppliers.

How it works

The system checks your inbox for emails with PDF or XML attachments.
It identifies which attachments are actual e-invoices and skips everything else.
It extracts the invoice number, dates, amounts, and seller and buyer details.
Each invoice is added as a new row in your spreadsheet.
