Generate ZUGFeRD invoices with Zapier and an API

Webhooks by Zapier can request a fakturai invoice from deal, form, or spreadsheet data and pass the resulting validated PDF to email, storage, or CRM steps.

What fakturai checks (KoSIT-Accept-Gate)

fakturai validates every generated invoice in 4 layers before delivery. The decisive step is the official KoSIT validator of the German tax authority returning “ACCEPT”. Full gate (XSD + EN 16931 Schematron + PDF/A-3b + KoSIT ACCEPT) for hybrid ZUGFeRD/Factur-X. For existing files use the free validator.

What fakturai does not replace (GHOA-1671)

The substantive and tax correctness of the invoice (amounts, correct VAT rates, service description, taxability, reverse-charge etc.) remains entirely with the issuer. No accounting/ERP functions, no tax or legal advice, no complete GoBD archival process beyond the file format. No hard guarantees or financial promises.
