We recommend that you make sure the file size is as small as possible before uploading the file to Penta. The maximum file size is 20 MB. DATEV recommends that the size of individual documents should not exceed 500 KB. However, the maximum size for all files in one synchronization process shouldn't exceed 20MB.

In the future we will send you a warning if the file size could be reduced.

You can find more information about the DATEV connection in our blog article and in our step-by-step instructions.
