E-invoicing is gathering momentum all over the world. With Interface E-Invoice, you’ll be all set for this transformation. Our solution gathers incoming XML invoices, captures their content, and automatically transfers the relevant information into the appropriate fields of your ERP system. For convenient further processing, the machine-readable document is also converted into an easy-to-read PDF. With Interface E-Invoice, you don’t have to choose between XRechnung and ZUGFeRD, as the solution supports both formats. It also supports PEPPOL BIS Billing 3.0 (which is standard in several European countries), the French Factur-X format, and InvoiceNow from Singapore. Other formats are currently being prepared.

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.
