How to match amount in sales receipts with overpaid/underpaid amount in bank deposits in Quickbooks online

Thanks for contacting us. If you go + symbol and bank deposit you can bank those 2 sales receipts as paid. you will not be able to match as the first one does not match the sales receipt so the system will be looking for a sales receipt for 125.00.  The alternative would be to instead doing an invoice for 100.00 and recording 125.as paid it should then create an unapplied payment for 25.00 then on a second invoice for 200.00 you could record the 175.00 paid and add the unapplied payment, then you should have a match. With it being a sales receipt what you are saying is that is what was paid on the day so it should not often be possible to overpay or underpay. If it was the case it had been paid in a bulk payment of 300.00 we would be able to use the find a match if that makes sense.
