Invoice Validation Tool
Check an invoice before you send it: required details, arithmetic and what a client can query.
Quick Tool Overview
The Invoice Validation Tool reads a pasted invoice the way a client’s accounts payable team does — checking that the required details are present, that the arithmetic adds up, and that any tax and bank numbers pass their own check digits.

About the Invoice Validation Tool
An invoice is rejected for boring reasons. No purchase order number, so it cannot be matched. No due date, so it goes to the bottom of the pile. A VAT number that is one digit out. A subtotal that does not match the lines, which makes an accounts team query the whole thing rather than the one line.
Paste the invoice — as text, from a PDF, from an email — and this reads it the way a client’s accounts payable team does. It looks for the details that must be there: an invoice number, both businesses, the dates, the currency, the line items, the tax treatment, how to pay. It recalculates the arithmetic it can find: the lines against the subtotal, the tax against the rate, the subtotal and tax against the total.
Then it checks the numbers that carry check digits — VAT, GSTIN, ABN, IBAN — and flags what is only well-formed rather than verified. Every finding says what is wrong and why it matters, so the fix takes a minute instead of a week of email. Nothing is uploaded.

Frequently asked questions
That the details required on an invoice are present, that the arithmetic adds up, that any VAT, GST, ABN or IBAN passes its check digit, and the practical things that get invoices queried — no PO number, no due date, no payment details.
No. It means nothing obvious is missing or contradictory. Requirements vary by country and by what you sell, so treat it as a proofreader rather than an auditor.
