With all of the changes to destination VAT charging etc, it is all too easy to make mistakes when editing invoices.
An exception report would be good which looks at:
a) Where the customer is not based in the home country (as per their Customer Profile Optiosn setting), but has been charged VAT
b) Where the customer has not been charged VAT but is based in the home country
c) Where the customer has not been charged VAT but is based in an EU member state
