Designed for businesses, entrepreneurs, freelancers, self-employed professionals, and SMEs, Billance helps you comply with mandatory e-invoicing regulations while streamlining your invoicing workflow.

- AI-powered invoice converter (Billance AI): Automatically convert traditional PDF invoices and invoice images (PNG, JPG) into structured electronic invoices using advanced artificial intelligence. A local template-based converter is also available.
- Professional e-invoice validator: Validate incoming and outgoing XML and PDF invoices within seconds to ensure compliance with e-invoicing standards and legal requirements.
- DATEV export: Export individual or multiple documents as DATEV-compliant accounting data for your tax advisor or bookkeeping.
