DATEV Buchungsdatenservice
Accounting entries and document images flow automatically into your tax firm’s DATEV environment. No batch emails, CSV imports, or document binders.
Autaxo
Transaction + document at the dealership
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.
The tax matrix
Autaxo is not a black box. We check every transaction for plausibility before it reaches your accounting system.
Case A: § 25a UStG / private purchase
Automatically calculates the margin and assigns the correct revenue accounts. VAT is not shown separately on the invoice.
Case B: standard VAT / EU
Validates the VAT ID (USt-IdNr.) in real time through VIES. Automatically documents tax-exempt intra-Community supplies (igL) under § 4 no. 1b UStG, the German VAT Act.
Case C: export to a non-EU country
Identifies export supplies and reminds the client to retain the required customs exit notes and evidence under § 4 no. 1a UStG.
Less rework during audits
Optimized for automotive clients, with clean structures, valid exports, and clear supporting evidence.
DATEV EXTF export as a fallback
Tax firms that do not use Buchungsdatenservice receive the standard EXTF/CSV export with consistent header and line-item fields, a correct file header, and a complete export history.
Digital vehicle file
Every external document, from the purchase agreement to customs evidence, is linked to the transaction and archived in compliance with GoBD, Germany’s digital record-keeping principles.
Automatic motor vehicle dealer’s register
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.
