Enterprise API for DATEV
The powerful API for full control over DATEV data – flexible, customizable, and expandable to suit your needs.
Full Control and Access
Get complete access to all fields in all DATEV desktop applications, such as accounting, tax programs, LODAS, reporting systems, or ProCheck and more.
Custom adaptations are possible – either by us or within your company. For teams and partners that want to connect assistant-style tools, we also offer an MCP server on top of the API.
Use Cases
Our customers use the API for various applications – the following examples demonstrate what is possible. In principle, we can access all relevant DATEV data. If a specific data point is missing, we can identify it through a defined process and extend the interface accordingly.
1. Controlling / Power BI Integration
Connect DATEV data with Power BI to create meaningful analyses and comparisons. Our API enables automated transfer of financial and accounting data into dashboards. This allows you to analyze and compare key figures at the firm, employee, or activity level – both within a firm and across multiple locations.
Typical reporting examples
Revenue and Contribution Margin
Get a fast view of revenue and contribution margin across the firm and per employee with monthly breakdowns.
Detailed Revenue per Client and Employee
Connect client outcomes with team effort to understand where value is created and where profitability differs.
Open Work Snapshots
Review historical snapshots of open work to identify turnaround times, bottlenecks, and billing delays.
2. Automated Corporate Tax Assessment Review
Automatically check corporate tax assessments by directly comparing them with DATEV data. Our API provides access to relevant information from entry forms and calculation lists, enabling you to quickly identify discrepancies and reduce manual verification efforts.
3. Automated Onboarding of New Clients
Transfer data from your existing system directly into DATEV and eliminate duplicate entries. Our API ensures that master data and relevant information are seamlessly imported, making the onboarding process efficient and error-free.
⚠️ Note: A separate SQL license may be required depending on the use case. We are happy to advise you.
