About the DATEV integration

DATEV is the accounting and tax software cooperative that most German tax advisors and their clients use. Unify Int connects to DATEV accounting data and bookkeeping exports through a Technology Center build.

DATEV integrations run through the DATEV marketplace programme, with APIs for accounting documents, bookkeeping data and master data that require partner approval. Unify Int delivers DATEV as a Technology Center build, including the partner process, and maps accounts, contacts and bookings to the Unify Graph.

Why build DATEV on Unify Int

  • One data model

    DATEV records arrive in the same Unify Graph shape as every other platform in the category, with the original record kept in raw.

  • Unify Connect

    A white-label flow for your customers to authorize DATEV. Tokens are stored and refreshed for you.

  • Custom fields and passthrough

    Map DATEV custom fields per connection, and call any endpoint the model does not cover through passthrough requests.

  • Unify Monitor

    Request logs, sync health and alerts for every DATEV connection, so support can see what happened.

DATEV integration questions

Does Unify Int support DATEV invoices and bills?
DATEV is available as a Technology Center build: we scope, build and maintain the connector for you on the Unify Accounting API. The planned scope covers accounts, customers, vendors, invoices, bills, bookings, tax rates and documents. Talk to the Technology Center to start.
How do customers connect their DATEV account?
Your customer or their tax advisor signs in with DATEV credentials (DATEV uses OpenID Connect and OAuth 2.0), once the integration is approved in the DATEV marketplace.
Is there a DATEV sandbox for testing?
Yes. DATEV provides a sandbox environment to approved development partners.
How often does DATEV data sync?
DATEV does not emit webhooks for most objects, so Unify Sync polls incrementally on the schedule you set per object, typically every 15 minutes to daily, and sends you signed webhooks when records change.
Can I access DATEV custom fields?
DATEV uses fixed bookkeeping structures (SKR03, SKR04 charts); account mapping is configured per client during the build.
