Use DATEV and VAT GPT together?

Yes, the jobs complement each other:

DATEV: exchange with the tax firm, receipt storage.
VAT GPT: evaluate marketplace reports, prepare the VAT return and the OSS return, export data.

You can export the data for your tax adviser, see data export for the tax adviser. If you are established only in Germany and your distance sales to other EU countries (together with certain electronic services) exceed 10,000 euros net (previous or current year), the VAT of the destination country applies (§ 3c Abs. 4 UStG). OSS is an optional procedure for reporting it centrally (§ 18j UStG; BZSt: One-Stop-Shop).

What this means for you: You do not have to choose between a firm and software; you share the work.
