EU e-invoicing tools (InvoiceVerify). Without signing in, check_peppol_receivability checks whether one Belgian company can receive Peppol invoices under its two Belgian IDs — 0208 (enterprise number) and 9925 (VAT number) — free, 20 checks per hour. With an InvoiceVerify account (OAuth sign-in): validate UBL / Peppol BIS 3 / XRechnung / CII / Factur-X XML against EN 16931 and Peppol rules, generate or convert compliant invoice XML, read invoices into JSON, check whether a company in any country can receive Peppol invoices (and under which Peppol ID), check lists of up to 25 Belgian companies at once with the risk and fix in Dutch, French or English, explain rules and show usage. Invoice tools use one metered call each; lookups use one call per company. Invoice contents are processed in memory and never stored.
