Hi We have just taken on a sum up machine to process customer card payments. How do I process this as a customer receipt and how do I account for the merchant fees?

Hello Orbro-reed, 

Welcome to the Community page, 

So what you would do is just split the incoming transaction you put in the full amount and then minus off the fees to the sum up fees you set up in the chart of accounts. If you have created a transaction when you go to match it you can then resolve the difference again by putting the difference to the fees in the chart of accounts. A notification should go to the customer that they have just used the sum up machine via text and then when the money hits your bank you add the transaction and as i said above just minus off the fee unless the payment is billed in bulk.
