Billing & finances with e-invoicing

From jump to invoice, from cash book to bookkeeping — full financial logic of a German dropzone. E-invoicing, GoBD, direct debit, batch invoices, payouts.

E-invoicing

Invoices the tax office understands.

Mandatory for German B2B invoices since 2025: XRechnung 3.0 as XML document, ZUGFeRD as PDF with embedded XML. Icarus Manifest generates both automatically, no extra cost, no third-party software. GoBD-compliant, immutable, archive-ready.

  • XRechnung 3.0 XML — ready to send to tax advisor & authorities
  • ZUGFeRD PDF with embedded XML — universally readable
  • GoBD-compliant: locked entries, versioning, gap-free numbering
  • Batch invoices for regular jumpers — weekly or monthly
  • Cancellation with full reversal of all side effects
