VAT Number Validation

All for one Steeb

Automatically verify the VAT numbers of your customers in your Cloud ERP-Platform


Jürgen Ravnik, Cloud Development, All for one Steeb SAP Excellence

Integrate the verification of your customer VAT numbers into your Cloud ERP platform. Your VAT number identifies you as a company within the European Union, enabling you to provide services and deliver goods. The correct VAT number is one of the requirements for the reverse charge procedure for taxable sales between EU countries.


Correct VAT numbers in the system

With the app for automatic VAT numbers verification you can ensure that you always have complete, correct and, above all, up-to-date VAT numbers of your customers. The automatic check identifies missing or incorrect VAT numbers at a glance and eliminates them from your system if necessary. You increase the quality of your customers VAT numbers and always have a perfect overview.

Control through updated database of the European Commission

The automatic VAT check via App is carried out using the constantly updated databases of the German Federal Central Tax Office and the European Commission via mass data run. You can thus check all your VATs at once and ensure that you have the correct, complete and most up-to-date data by comparing them with the databases. The interval settings of the app also allow you to repeat the mass data runs as often as you like, which ensures even more security and data quality. In addition, you can have your customer Vat numbers checked in customer invoices for your reverse charge procedure for taxable sales between EU countries.
