Check an e-invoice before the government portal rejects it.
InvoiceCheck EU reads an electronic invoice on your computer, checks it against EN 16931 business rules and tells you in plain English what to fix. The invoice is never uploaded.
Not for sale yet. We are testing it on many kinds of real files and measuring what it does on an ordinary PC. The version, the price and the measured results will be published here when it has passed.
Who it is for
Accountants, ERP integrators and e-invoicing consultants, and any business whose client agreement forbids uploading invoices to an online validator.
What it does
InvoiceCheck EU in short
Four ways in
Reads UBL 2.1 (the format behind XRechnung and Peppol BIS), UN/CEFACT CII (ZUGFeRD and Factur-X) and PDF/A-3 files with the invoice XML inside.
Every field found
Shows each business term the invoice contains, numbered the EN 16931 way, so you can see what the invoice really says.
Plain-English fix cards
Each failed rule becomes an instruction a person can act on, instead of a code like BR-CO-15.
VAT and an audit record
A VAT breakdown and a record that the check was done, for your files.
Hostile XML is refused
Files that try to attack an XML parser are rejected before they are read.
Open an invoice, press validate, read the fix cards, correct the invoice in your own system and check again.
Your data
It stays on your computer.
The invoice, its supplier details and its prices stay on your computer. The program opens no network connection.
Honest limits
What InvoiceCheck EU does not do
- It checks a first set of EN 16931 business rules (eight so far). The complete official rule sets are not built in yet.
- A pass therefore does not guarantee that a tax portal accepts the invoice. Treat it as a careful first check.
- There is no command-line mode yet, so it cannot run inside an automated pipeline.
- It checks invoices. It does not create or sign them and does not send them through a network.
