I work with two QF accounts, one being VAT registered and the other not VAT registered. The VAT registration number is an available field to store this information on the VAT registered account but this field is unavalable in the non-VAT registered account.
Why include the facility for all QF user accounts? The ability to verify the VAT status and registered address is a useful tool to confirm the details received which also helps to do a simple “credit check”.
The Companies House search facility is an available tool for all users, so a similar facility seems appropriate for VAT numbers.
