I have managed to finally add the processing fees and match up thank you. However this only works when creating an invoice not a sales receipt, is that correct?  Is there a way for quickbooks to automatically calculate the go cardless processing fee or do I need to enter it every time. it seems to be a very tedious way of doing things. 

I have made a dogs dinner of my accounts in this learning process :-). I am trying to delete some sales receipts and invoices where I have made undeposited submissions. I am unable to delete them from the invoice/sales receipt tab under delete. I cannot delete them from the undeposited section on the chart of accounts either, nor the audit trail. I have a 'popup' in red saying: "this transaction has been deposited. you must edit -delete the deposit it appears on and remove it first". Is it possible for you to guide me on how I can locate and delete these transactions?
