Frequently asked questions
Is the archiving GoBD-compliant?
Yes. Colly.io archives all tax-relevant documents immutably with timestamp and user reference. The requirements of GoBD (principles for proper bookkeeping and archiving) are fully met.
How does the DATEV export work?
In the accounting section you can select a period and export a DATEV-compliant CSV file. This contains journal entries, account numbers and tax keys and can be imported directly into DATEV Unternehmen Online.
What is ZUGFeRD and do I need it?
ZUGFeRD is an invoice format that embeds machine-readable XML directly into the PDF invoice. It enables automatic booking at the recipient. From 2025, e-invoicing will be mandatory for B2B transactions in Germany – Colly.io meets this requirement.
