DATEV export & ZUGFeRD now available

Today's update brings Colly.io's complete accounting integration for the German market. Two long-awaited features are now available: DATEV export and ZUGFeRD invoices.

DATEV Export

Colly.io now exports DATEV-compatible CSV files with journal entries, accounts, and tax keys. The files can be directly imported into DATEV Unternehmen Online or DATEV Kanzlei-Rechnungswesen. All bookings are automatically generated from processed orders - without manual rework.

ZUGFeRD Invoices

All outgoing invoices are now created as ZUGFeRD-compliant PDF/XML hybrid format. This means machine-readable invoice data is embedded directly in the PDF. Ideal for automated processing on the customer side.

GoBD Compliance

All documents are archived in a GoBD-compliant and revision-proof manner. Subsequent modification of closed accounting periods is technically excluded.
