Checks we added ourselves, not taken from a schematron: the shape of the XML file, CII syntax, IBAN, VAT number, Leitweg-ID, dates and currency.
The group has 13 rules. Source: our own check at ARLing, not from a schematron.

Check the whole file
The checker holds 332 rules. For each file it runs the ones that match the invoice profile and shows the rule code, a plain sentence and the path to the element for every finding. The file is read in your browser and never uploaded. Free, no account.
What our tool does about this error
The checker finds these codes in your file and shows where they sit in the XML. If you build the invoice in our generator, the finished XML runs through the same checker before the download and will not download while an error remains.
The checker and the preview cost 0 € and need no account. Downloading the finished XML costs 2.90 € excl. VAT, unlocked in the browser for 24 hours, or 9.90 € excl. VAT for 30 days including the CSV batch.

Our check is not complete: we do not check the XSD schema and we do not implement every rule, and a file that passes says nothing about whether the buyer or the Peppol network will accept it. The source of each quoted wording is given next to the quotation.
