DATEV
Accounting simplified
Transferring your invoices to your tax advisor. With BCS, you can set up DATEV integrations for invoice, expense, and accounting data—tailored to your specific needs. For payroll and accounting, use the CSV export of all attendance and transaction data for further processing with DATEV.
Interface examples
In collaboration with our customers, we have already implemented several BCS interfaces in DATEV, for example in the following areas of application:
DATEV company Online
Export of outgoing invoices and expense data from BCS to DATEV Online
Transmission of scanned receipts
Classifier fields needed for configuration
XML is used here
DATEV Pro
Export of outgoing invoices and expense data from BCS to DATEV-Pro
Classifier fields needed for configuration
ASCII is used here
How DATEV Integration Works
Integration with DATEV is based on proven scenarios but is customized to fit your specific system environment and processes.
Depending on the target system—such as DATEV Unternehmen Online or DATEV Pro—different formats like XML, ASCII, or CSV are used. The transfer of document images (e.g., PDF invoices or expense receipts) can also be integrated.
Requirements & Notes
Certain technical and organizational prerequisites are required for successful integration with DATEV. These include, among others:
Use of DATEV Unternehmen Online or DATEV Pro
Use of DATEV document transfer
Maintained master data such as customer and vendor numbers
Provision of export files from BCS
The specific requirements vary depending on the integration scenario and are defined jointly during the project.
Flexible CSV Export: Payroll Accounting with Accurate BCS Data
To reliably support data transfer into your DATEV accounting solution, you can use the option for flexible data export from BCS in CSV format. This allows you to export attendance and transaction data from BCS and make it available for further processing for payroll calculation and payroll accounting.

With clear processes and structures, BCS provides lasting relief, maximizes the benefits of data maintenance across all process steps, and enables the simultaneous management of multiple clients without switching systems. The integration of external project stakeholders, as well as flexible interfaces—such as those with in-house systems and DATEV—further enhance efficiency and adaptability.

“All in all, we were able to achieve enormous time savings by invoicing through BCS in conjunction with the DATEV export.”

Ursula Meyer
Delivery Manager, Be Shaping The Future - Performance, Transformation, Digital GmbH, Munich
We also use the BCS-DATEV interface for the integration between “Projektron BCS” and “DATEV Unternehmen Online”.

Thomas Hackenbuchner
Head of Finance & Administration, MicroNova AG
"MicroNova also uses BCS for the actual invoicing, as enormous time savings can be achieved in connection with the DATEV export. Not only outgoing invoices to customers are processed, but also "intercompany invoices" within the group."
Customized DATEV Integration
The DATEV integration is not a preconfigured standard interface, but is implemented on a project-specific basis. Due to the specific requirements of DATEV, the appropriate integration solution is developed together with you במסגרת a workshop.
In this process, we define data flows, formats, and processes – from invoice transfer to payroll accounting.
Using our web service or the import-export module, we implement a solution that is precisely tailored to your requirements.
