Sales Receipts matching downloaded Bank transactions
I am doing some accounting work for a plastic surgeon who only accepts Cash/CC at time of services rendered. His books need to revised for 2019 as the last accountant did not enter any kind of invoice or sales receipts for payment received from patients. I have downloaded all 2019 bank transactions so I have "merchant deposits" that are made up of multiple customer payments. What would be the correct way to allocate or match those payments with each customer to show correct income?
