Business Systemhaus AG develops tax extension for Microsoft Dynamics 365

The tax landscape in Germany

DATEV is a software and IT services cooperative for tax professionals. Many companies in Germany rely on a tax advisor or use DATEV software in-house.

Building on Microsoft technology

Business Systemhaus AG saw a market need for a convenient way to transfer tax data, so it created the BSH DATEV Connector, an extension for Microsoft Dynamics 365 Business Central.

With the extension, users can export financial data from Dynamics 365 to the DATEV pro format and import DATEV data to Dynamics 365.

Working with Microsoft products

A Microsoft partner for many years, Business Systemhaus AG focuses its consulting and IT services on Microsoft Dynamics 365 Business Central, Microsoft Dynamics NAV, and the Microsoft Office 365 Suite. Business Systemhaus AG has Gold Enterprise Resource Planning and Silver Small and Midmarket Cloud Solutions competencies.

The company endeavors to build optimized IT environments for small and midsized businesses so they can concentrate on their core activities.

“With Microsoft, we have a reliable partner to meet the needs of our small and midsized customers, regarding the digitalization of their businesses,” said Wolfgang Eichfeld, CEO of Business Systemhaus AG. “One of the key benefits of Microsoft solutions like Dynamics 365 Business Central and Office 365 is the great collaboration between the applications. Microsoft enables us to create future-proof solutions. The platform Microsoft created through its product strategy gives us all the necessary tools to support our customers in achieving their goals.”


DATEV Connector development

The BSH DATEV Connector’s development is based on Business Systemhaus AG’s DATEV interface for Dynamics NAV, which passed technical examination by DATEV, was officially certified for Dynamics NAV, and was published in the DATEV marketplace.

The BSH DATEV Connector’s functions include mapping the DATEV account numbers per G/L (general ledger) account in Dynamics 365 Business Central. Data is exported for G/L accounts, customer/vendor master data, and related items, as well as terms of payment, where foreign currencies are taken into account. The application supports the export of data via gross or net method and offers different reports, like a DATEV journal and a data integrity test. Optionally, DATEV data can be transferred to Dynamics 365 Business Central using various check mechanisms. The DATEV Connector ensures intuitive operation via various wizards and additional consulting services.

The DATEV Connector is compatible for multitenant environments, and its integration into the authorization system of Dynamics 365 Business Central ensures safe and reliable work. Through the mapping of the G/L accounts in Dynamics 365 Business Central with the standardized DATEV account numbers, the DATEV Connector enables the easy export of financial data, facilitating collaboration with tax advisors.

“One of the key benefits of Microsoft solutions like Dynamics 365 Business Central and Office 365 is the great collaboration between the applications. Microsoft enables us to create future-proof solutions.”
