Do you ALWAYS remember to validate your EU customers’ VAT number?

OptiVIES proves your validation

Your company is obliged to ensure the validity of your European customers’ VAT numbers.

OptiVIES automates the validation process in your Dynamics AX or Dynamics 365 Finance and Operations (D365FO) so that you can always document that the validation is done in accordance with the applying rules.

The solution connects to a Cloud server in the EU where the VAT numbers are regularly validated in the individual countries. Subsequently, you will receive a confirmation code which OptiVIES stores electronically so that you will be able to account for the validation at any time.
