e-Invoicing Standards
Invoice.app integrates with national and international e-invoicing systems so you can stay compliant wherever you do business.
KSeF — Poland
Krajowy System e-Faktur is Poland's mandatory National e-Invoicing System. Invoice.app fully supports KSeF 2.0 — submit, receive, sync, and manage structured e-invoices directly from the app.
Coming Soon
ZUGFeRD — Germany
Germany's hybrid e-invoicing standard combines a human-readable PDF/A-3 with embedded XML data, aligned with European standard EN 16931. B2B e-invoice receiving became mandatory in Germany on January 1, 2025.
More countries coming soon
We're expanding support for additional e-invoicing standards across Europe and beyond.
