Supplier invoices arrive as PDFs and somebody types them into a sheet. This does that part.

It pulls out the supplier, the invoice number, the date, the due date, net, VAT, the total and the VAT registration number, and writes one row. It reads 4,248.00 and 4.248,00 as the same number, so a UK invoice and a Romanian one land in the same column. It will not let Subtotal pass as the total, and it will not read a VAT registration number as an amount.

The check that earns its keep is the duplicate one. Suppliers resend, accounts forward, the same invoice turns up twice looking perfectly legitimate. It matches on supplier plus invoice number plus amount, not on the file name, and stops. Nothing written, nothing sent to accounts, and you are told once.

When it cannot read something with confidence it does not guess. The invoice is parked for a human, with the reason, and nothing is written to the sheet.

Built on n8n. Gmail and PDF text extraction go in front of it; Google Sheets, Airtable or a database goes behind.

You get the flow built and tested on your own accounts, a short video of it working, and the source handed over.

Adapted to your business, with one round of adjustments included. Anything past a small adjustment, like a new channel, integration or feature, is quoted separately before any work starts, so the price is never a surprise.
