Is this invoice
worth a second look?
Drop in a PDF or image invoice — or paste the text — and Aptosi runs standard open-source checks on how it was built and whether the numbers add up. It is a prompt to verify, never an accusation.

What a single file can't see
A one-off document scan can't see the things that actually catch modern invoice fraud: the vendor's payment history, the email it rode in on, or a recent change to bank details. Aptosi watches all three across your inbox — this free check runs only the commodity, open-source part.
Runs standard open-source checks only; the Aptosi platform does substantially more. Results are educational signals to help you decide whether to verify with the sender — not a determination that any document is fraudulent, altered, or authentic.
