Let me guide you in the right direction on how to handle your sales receipt and open invoices, kk74.

In QuickBooks Online (QBO, you can create an invoice to be paid later. While a sales receipt is used for real-time or immediate payments. Keeping both will double your income because they're the same sales transactions.
