One customer has been paying what he thinks he should, NOT what I invoice. I have used 'receive payments' and applied to earliest open invoices. I now noticed GST received and payable is not as much as it should be. It seems I have to apply to a current invoice, NOT any in a prior BAS period (cash tax), or the BAS doesn't show GST from customer.
Can someone confirm this. I presume changing payments deposited from invoices in an older period to invoices in the 'correct' period will alter past BAS figures - what to do?
