Welcome to the Comsol USt-ID Validation

With the Comsol USt-ID validation you can validate the foreign VAT registration numbers of your customers, vendors or contacts directly on the master data record or by batch run. This is a qualified validation with the online interface at "Bundeszentralamt für Steuern (BZSt)".

The validation and visualization of the results is done via an info box, which is automatically integrated into the customer list and card, vendor list and card and contact list and card when this app is installed. Optionally, an automatic check can also be activated when sales orders are released.
