For invoicing, ERP and plugin vendors
Pricing
Independent conformance checks of the e-invoices your software produces. One-time payment, no subscription.
One-time check
Your invoices are run through KoSIT 1.6.3 (XRechnung 3.0.2), the CEN EN 16931 rules, Peppol BIS 3.0.20 and our amount-due self-checks. You get a written report with the failing rule IDs and fix guidance per invoice, within 3 business days.
Vendor audit
Systematic test cases across VAT categories S, E, AE, K, G, O, allowances/charges and rounding, in each format you produce (e.g. UBL, CII, XRechnung, Factur-X), against the same validators. Written report with fixes. Includes one re-test after your fix.
After paying, email the invoices (or how to generate them) via the Get checked page. Prefer bank transfer or want to try first? One invoice is checked for free: see free check or the browser self-check. Results reflect the validator versions named above at the time of testing; this is not a certification.
