Absolute Excel VAT Filer  

This error is usually caused by the formatting of the information that has been linked to the VAT Filer.

The most common cause of this is where the VAT number contains spaces, letters, or character such as – or /. We have also seen this message when the 9 digit VAT number has been entered incorrectly. Also the regional settings on the machine need to be set to English United Kingdom as does the date format.
