Thanks for getting back to this thread, @ccf2. Let me share insights on how you can create a payment receipt in QuickBooks Online.

The sales receipt is a different sales form, it is used any time your customer immediately pays for products or services at the time of sale. This is in contrast to invoices, which you give to customers who plan to pay for their purchases later on.

To issue a payment receipt, you can open your customer's invoice payment, then either Print it or click on Save and send.

Keep in mind that generating sales for the invoice partial payments would double your sales entry.
