According to the German accounting guidelines, receipts and invoices must be traceable, verifiable at any time, complete and not modifiable.
Once you have transferred your vouchers to the DATEV voucher image service (formerly DATEVconnect online), they can no longer be changed or deleted in Penta. However, it is possible to upload new vouchers or invoices.
Therefore, please check that all receipts are correct before transferring them.
This is also the first step in ensuring that your company complies with the GoBD guidelines (principles for the proper keeping and storage of books, records and documents in electronic form and for data access).
