# InvoiceVerify

> EU e-invoice validator, converter and Peppol ID lookup. Checks UBL 2.1, Peppol BIS Billing 3.0, XRechnung and Factur-X / ZUGFeRD invoices against 152 EN 16931, Peppol and XRechnung rules, explains errors in English, Dutch and French, and tells you whether — and under which Peppol ID — a company can receive e-invoices.

For Belgian bookkeepers it checks whole client lists (up to 500 companies) under both Belgian Peppol IDs — 0208 (enterprise number) and 9925 (VAT number) — and says per company whether invoices arrive under both, only one or neither, with the fix in Dutch, French or English. The first 10 rows of a list are free; Pro checks the whole list, exports CSV and re-checks saved lists every month.

AI agents and automations can use the same checks through a REST API (Bearer API key) and a remote MCP server named InvoiceVerify (server ID app.lovable.peppol-invoice-compass/invoiceverify). Without signing in, the MCP tool check_peppol_receivability checks one Belgian company under 0208 and 9925 for free (20 checks per hour per visitor); every other MCP tool needs OAuth sign-in with an InvoiceVerify account. Every validate, convert, generate, parse or Peppol lookup call uses one metered call (a Belgian list check: one per company, up to 25 per request): 100 per month free with an account, 1,000 on Pro (€14/month or €99/year, excl. VAT), plus prepaid packs (2,000 calls for €19, 10,000 calls for €79, 50,000 calls for €299, excl. VAT). In the browser, 3 validations per month are free without registration and single Peppol lookups are free. Invoice contents are never stored.
