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.
ZUGFeRD & XRechnung — Germany
ZUGFeRD and XRechnung are Germany's two accepted B2B e-invoicing standards, both based on European standard EN 16931. Invoice.app generates both — a ZUGFeRD PDF with embedded XML, or standalone XRechnung XML for public-sector recipients.
Coming Soon
Factur-X — France
From September 2026, all French B2B invoices must be issued and received through state-approved platforms (Plateformes Agréées). Accepted formats include Factur-X, UBL, and CII. Businesses must also e-report B2C and cross-border transactions. SMEs follow in September 2027.
Coming Soon
VERI*FACTU — Spain
VERI*FACTU sets technical rules for invoicing software rather than a new invoice format. Each invoice carries a QR code and a tamper-evident billing record, sent to the AEAT in real time or held signed and unalterable. Mandatory for companies from January 2027, sole traders from July 2027.
More countries coming soon
We're expanding support for additional e-invoicing standards across Europe and beyond.
