Typing out old paper bank statements is prone to errors, takes hours, and is no fun for anyone. In particular, scanned PDFs cannot be copied - every booking has to be laboriously entered into Excel or DATEV.
With KontoCSV, the AI does this work in seconds: you upload the scan, the bookings are recognized, normalized and made available as a structured CSV or DATEV export. No copy & paste, no typos.
Time savings in numbers
5 minutes per page when typing vs. 30 seconds per page with KontoCSV. With 120 pages you save around 10 hours.
In addition, IBANs, booking texts, value dates and amounts are automatically validated.
Why scanned bank statements are so tedious
Crooked scans, stamps or handwritten notes.
OCR error: 1 and I, 0 and O, decimal separator.
Missing structure: date, booking text, IBAN, amount mixed.
No plausibility check for balances and signs.
Robust OCR for old, slightly faded scans.
Field assignment: date, value date, purpose, IBAN, amount.
Validation against balances and totals.
Export profiles for DATEV, Lexoffice, sevDesk & banking apps.
