Facturwise
Facturwise is an invoicing platform for EU freelancers and small businesses with ZUGFeRD and Factur-X e-invoicing compliance built into every plan — including free.
Germany mandates e-invoicing from 2027, France from September 2026. Most tools charge extra for compliance or don't support both standards. Facturwise generates fully compliant ZUGFeRD 2.4 and Factur-X 1.0.8 invoices automatically — no plugins, no configuration, no extra cost.
Every invoice is a hybrid PDF/A-3 document with structured CII XML embedded inside — human-readable for your client, machine-readable for their accounting software.
Beyond compliance: multilingual invoices in 6 languages, 30 currencies, SEPA QR codes for zero-fee bank transfers, automated recurring billing, payment reminders, expense tracking, client management, quotes, credit notes, and a financial dashboard.
Start free, no credit card required.
