CX Estimation GAEB processing directly in Microsoft Dynamics 365 Business Central

Import - calculate - plan: GAEB interface and Gantt Chart

Another impressive feature of our calculation software for the construction industry is the integrated GAEB interface. This interface enables smooth data exchange between the calculation module and other systems that support the GAEB format.

With CX Estimation, you can import all data quickly and easily via the GAEB interface. Both imports and exports are transferred electronically to the relevant systems. After importing, the files are opened directly in Microsoft Dynamics 365 Business Central and can be edited there in the ERP system. The adoption of the tender structure is particularly helpful here. In the CX GAEB Viewer, you can already see the requirements and structure of the tender without prior import, thus avoiding unnecessary data exchange.

Offer structures already in the system are automatically set and also displayed. You can simply add or remove items via drag & drop. Created quotations are easily exported to the corresponding GAEB format at the touch of a button (support of various GAEB formats: GAEB 90 and GAEB xml – 83 or 84).

Once the order has been placed, all the data is already available in the system and can be converted into an order. For smooth project planning, there is seamless integration with the CX Planner project module. You always have a clear planning board with which every project can be implemented safely and efficiently.
