How do you record a receipt that lists both a credit and expenses on the same receipt? The credit was bigger than the expenses, so the total ends as a credit.

For a Vendor/supplier purchase enter purchase as a bill. Then enter a vendor credit for the entire credit. Apply the credit to clear the bill and you are left with a credit balance for future use.

For a customer enter an invoice and then receive payment to create a credit or create a full customer credit and apply to invoice
