DATEV Unternehmen Online as part of your operational system – not as an isolated solution.
Connect DATEV Unternehmen Online – Customized and Seamless
DATEV Unternehmen Online is the central platform for digital collaboration between businesses and tax consultants. Receipts, booking data, bank transactions, invoices – everything runs through DATEV. For most mid-market companies in Germany, DATEV is not optional. It is a given.
The problem: DATEV is good at what it does. But it doesn’t communicate with the rest of your company. Data must be manually exported, processed in Excel, and transferred to other systems. This costs time, generates errors, and prevents financial data from reaching where it is needed operationally.
We integrate DATEV Unternehmen Online into customized enterprise software. No pre-made standard connection, no plug-in with limitations – but a tailor-made integration via the DATEV API that precisely fits your processes and your system.
What We Can Integrate
Depending on the project and requirements, we connect different DATEV data services. Here are a few examples:
| Integration Possibility | |
|---|---|
| 📄 | Transfer Receipt Images – Automatically send invoices and receipts to DATEV Unternehmen Online |
| 📊 | Synchronize Booking Data – Automatically transmit structured booking records |
| 🏦 | Reconcile Bank Data – Automatically process account movements and transactions |
| 🔄 | Keep Master Data in Sync – Match customers, suppliers, and account frameworks between systems |
| 📥 | Transfer Structured Invoice Data – Include machine-readable data (XML) when transferring receipt images |
The exact integration depends on your processes. We work with the official DATEV interfaces – Booking Data Service, Receipt Image Service, Invoice Data Service – and develop the integration to ensure it fits seamlessly into your system.
How the Integration Works
We work directly with the DATEV Online API and the official DATEV data services. The connection is developed as an integral part of your Operating System – no third-party middleware, no workaround.
What This Specifically Means:
| 🏗️ | Custom Connection – built for your processes, not for the average |
| 🔄 | Automatic Data Flow – Receipts, bookings, and bank data flow without manual export |
| 🗄️ | One Data Source – DATEV data is part of your central system, not a separate island |
| 🛡️ | Secure and Compliant – encrypted, GoBD-compliant, GDPR-compliant |
| ✅ | DATEV Approval Process – we undergo the official approval process from DATEV |
Typical Use Case
A mid-market service company creates several hundred invoices each month. Until now, invoices were generated in the ERP, saved as PDFs, manually uploaded to DATEV Unternehmen Online, and processed further by the tax consultant. Error rate: high. Time spent: several hours each month. And when the tax consultant had a question, context was often missing.
After integration: Invoices are created in the operational system. Receipt images and structured invoice data are automatically transmitted to DATEV – including correct account assignment and receipt linkage. The tax consultant works immediately with complete data. No export, no upload, no inquiries. Saving hours each month, fewer errors, faster closings.
Part of Your Operating System
DATEV Unternehmen Online is a good tool for collaboration with the tax consultant. But used in isolation, it remains an isolated solution – a one-way street where data must be manually pushed in.
Only as part of an integrated system does DATEV unfold its full utility: when receipts flow automatically, booking data is synchronized, and financial data is available where operational decisions are made. Without manual effort. Without media breaks.
We develop AI-powered Operating Systems for operationally complex companies. The DATEV integration is one component of this.
