Northern Island VAT issue

SOLVED

Good afternoon, I wonder if you can help me. We have a customer in Northern Ireland who we deliver goods to.

When I ran VAT return, the VAT element of those invoices is not on VAT return (it is thought included in TB-2200), therefor I always have a difference.

The net amount of these sales is always included in column 8. How do I adjust for the difference between my VAT return and TB? Many thanks Nik
