Do I charge VAT. Here is his reply:
" Vat rules You need to identify B2B and B2C UK, EC and outside EC customers. A vat registration number is usually accepted as evidence of B2B.
1 All sales outside the EC have no vat implications and are ‘outside the scope of vat’.
2 All sales to UK customers (B2B and B2C) have UK vat to apply to them and are standard rated.
3 All B2B sales to EC customers have no vat and are ‘outside the scope of UK vat’.
4 All B2C sales to EC customers have UK vat to apply to them and are standard rated.
There is a further twist. If you can identify where your service is effectively used/enjoyed, then If the place of supply would be the UK (2&4) but the service is enjoyed outside the EC, then no vat (outside the scope) or If the place of supply would be outside EC (1) but the service is enjoyed in the UK, then UK vat applies."
