A customer payment got assigned to another customer in last vat period, so its locked now
Need to correct this as both customers up in arms about it
Can QF do this behind the scenes if I provide the details or is there a way to override the vat lock
I would say credit noting the invoice with the wrong payment would be the easiest way to solve this.
The only way to fully unlock those entries would be to rollback the VAT return, but you may end up with different values on the return when you reapply if any payments were subsequently entered to that period, it’s a bit risky!
Personally I would credit note it if you can.
