Frequent questions and problems:


  1. The DATEV transmission can take place fully automated. This can be activated in the Sync settings. Naturally, manual transmission is also possible.
  2. You have the option to transmit the document image or PDF only, or the entire meta data.
  3. In case you select “Meta Data”, you must ensure that all data is present and correct. -> Please note: When you choose a transmission including data, we recommend manual approval before the transmission. Please also check the sync settings under Edit Sync. Account -> Extended Settings -> Document Settings -> Approval. Additionally, you can adjust your settings under “Tagging”, so that only controlled invoices with the tag “verified” will be transmitted. To do so, please configure the appropriate tags in the sync account settings.


  1. “The user has no access to clients. It is recommended that the user contact the tax consultant.” -> Find the solution here.
  2. “Not allowed for {year} fiscal year.” -> Please perform the synchronization again, so we receive the updated client data. Should the error continue to be displayed, please check the following: The inventory for the book has not been created yet. A new mandate for Documents online/Cash Book online has to be created in Unternehmen online (see). Or: Only the correct fiscal year is missing for the inventory. In this case, a year transfer has to be carried out (see item 2.1, 2.2, 2.3)
