## Invoice-Converter vs sevDesk

sevDesk is accounting software that also covers German e-invoice formats such as XRechnung and ZUGFeRD. Invoice-Converter focuses on converting invoice inputs produced outside your accounting suite and validating the structured result.

sevDesk is for self-employed people and small businesses that want to create, send, and book invoices in one accounting product. Invoice-Converter is for teams that keep their current ERP or billing setup and need its PDF or mixed-format output turned into compliant XRechnung, ZUGFeRD, UBL, or CII files, with extraction, a review step, and centralized validation instead of a system migration.

When is sevDesk the better choice? If you are picking your first accounting tool, or you want invoicing and bookkeeping in one German suite, sevDesk is the better starting point. Invoice-Converter is the lower-disruption option when invoices originate outside the suite: supplier PDFs, a legacy ERP, or a billing system that cannot produce compliant e-invoices yet.

## Choose your workflow

- Use Invoice-Converter when invoices come from suppliers, legacy ERPs, PDFs, or ad hoc sources
- Use sevDesk when you want bookkeeping, invoicing, archiving, and accounting workflows in one suite
- Invoice-Converter keeps compliance review explicit with field guides and KoSIT rule explanations

## Frequently Asked Questions

### Can I use both?
Yes. A common pattern is to keep bookkeeping in an accounting suite and use a specialist converter when invoices originate outside that suite or need independent validation before submission.

### Do I have to replace my billing software for the German e-invoicing mandate?
No. Since January 2025, German businesses must be able to receive e-invoices; issuing becomes mandatory in stages, from 2027 for companies with more than 800,000 euros previous-year turnover and from 2028 for all domestic B2B transactions. You can keep your existing ERP or billing system and convert its output into compliant XRechnung or ZUGFeRD instead of migrating.

### Is sevDesk or Invoice-Converter better for XRechnung?
If you create your invoices inside sevDesk, its built-in e-invoicing is the natural path. If invoices come from a legacy ERP, suppliers, or PDFs, Invoice-Converter converts and validates them without changing where the invoices are created.

### Can Invoice-Converter replace sevDesk?
No. Invoice-Converter is not bookkeeping software: it does not handle accounting, bank reconciliation, or tax filing. It converts existing invoice documents into compliant structured formats and validates them. If you need a full accounting suite, sevDesk is the right category.
