Thanks again. The problem I have is I often hold on to cash for a week or so before paying it in and pay in one lump sum. So when pupil has lesson and pays £42 cash I generate an invoice and then mark it as paid. The issue is I may then pay in £500 odd pound in one lump to the bank so can't see how I can allocate individual payments unless they pay by bank transfer.

The work around I am using is to save each invoices as a PDF and then email them to quickbooks. Then edit each one and change the amount from  -£42 to plus £42 and categorise as Business income. This just takes some time. I can't see why a button could not be added so when you mark an invoice as paid it could be added as business income automatically?

Thanks for your input.
