DATEV

Entry + document image at the tax firm

No more import step

Accounting entries arrive directly at your tax firm through the API. No CSV transfer, EXTF import, or manual step in the accounting application.

Document image included

Incoming and outgoing documents are transferred with the matching accounting entry and are visible in your tax firm’s DATEV system.

Daily updates instead of a monthly data dump

BWA management reports and analyses stay current instead of becoming a monthly data package that requires follow-up work.

Fewer follow-up questions

The document, preliminary account assignment, § 25a UStG logic, and notes remain attached to the accounting entry. This eliminates the most common clarification requests.

Setup takes minutes: enter the advisor and client numbers in Autaxo. The client initiates the connection, and you receive accounting entries and documents in DATEV.  See how it works in 30 minutes.

Autaxo automatically maintains the legally required Kfz-Handelsbuch, the motor vehicle dealer’s register under §§ 143 and 144 AO (German Fiscal Code). Ideal for tax audits.

Frequently asked questions from tax advisors

What is DATEV Buchungsdatenservice, and how does it work with Autaxo?

DATEV Buchungsdatenservice lets Autaxo send preassigned accounting entries and the associated document images directly to your tax firm, with no CSV transfer or manual import. The client enters the advisor and client numbers in Autaxo once; accounting data and documents then flow into your DATEV environment each day.

Do I need DATEV Unternehmen online?

DATEV Unternehmen online is the standard tax-firm solution for transferring document images. Accounting entries alone can also be transferred without Unternehmen online. Documents are then provided separately through a link on the accounting entry or as a ZIP download.

Will DATEV EXTF export remain available?

Yes. The standard EXTF/CSV export remains available as a fallback for tax firms without DATEV Cloud or as a manual backup route. A sample export is available for download in the hero section above.

What if the tax advisor does not use DATEV?

No problem. DATEV accounting batches in CSV/EXTF format are the de facto standard in Germany and can be imported by virtually all leading tax-firm systems, including Agenda, Addison, Stotax (Stollfuß/NWB), Simba, and Lexware Office. Your tax firm simply selects the DATEV import for accounting batches in its software and continues working as usual.

Does tax-firm access cost anything?

No. Access is permanently free for tax advisors and bookkeeping firms. There are no license fees.

Which charts of accounts are supported?

We support SKR03 and SKR04, as well as SKR51, the specialized German chart of accounts for the motor vehicle trade. Account assignments can be customized in the tax-firm dashboard.

How do I receive the documents?

The DATEV export includes a link to the digital document image for every accounting entry in Belegfeld 2, DATEV’s supporting-document link field. Alternatively, you can download all documents as a ZIP file.
