Thank you for the detailed reply. I would be keen to keep the query open to other responses.
Perhaps it's the pricing structure we use, you mentioned 'simplified pricing', but there are no export fields that cover the total amount paid by the guest.
I have opened a query with technical support perhaps they can shed some light.
And I agree that closing the doors is probably the easiest solution and yes, the vat is £85,000 (it goes up to £90,000 tomorrow).
Thanks again.
Stuart.
