Export and archive your books
Hand over your accounting as Banana, Abacus, DATEV, Excel or CSV files, and keep a legal archive for 10 years.
Your accountant may work in another program. IDup exports the books in the formats they use, and it keeps a complete archive for the retention period.
Export
- Banana: transactions and Banana: chart of accounts — text files for Banana Accounting.
- Abacus: GL entries (XML) — the AbaConnect XML entries format. Importing needs AbaConnect in Abacus.
- DATEV: posting batch (CSV) — enter your consultant number and client number first.
- Journal and Chart of accounts as CSV or Excel.
Click Download next to the format. CSV files use a semicolon and UTF-8.
Legal archive
- Click Create legal archive.
- IDup builds a ZIP with the journal, the reports, the audit log with its hash chain, the receipts, the VAT returns and the closings.
- Each file carries a checksum. The archive is stored unchanged and can be downloaded again at any time.
Keep it for 10 years. IDup also offers an Archive tab that files the year-end records with a deletion lock until the retention period ends. Before you confirm, IDup shows what will be filed.
Import a chart of accounts
Upload a CSV or Banana file. You see a preview first. New accounts are created. With Rename existing accounts chosen, names are updated. Nothing is deleted.
Nothing is tracked — the buttons only open a message so you can tell us what was missing.
