Hello there, @WinginIT.

At this time, recording a single sales receipt with two different payment method isn't available. You can consider creating two sales receipts for every payment method and enter a description to specify the transactions. 

I can see how much time you can save without entering another sales receipt for a different payment method. However, creating two sales receipts for different payment methods is the best way we can do.

To learn more about sales receipts, feel free to check out this article for more guidance: Create sales receipts.

Just in case you want to add a discount to a sales receipt, you can check out this article for the detailed steps and information: Add a discount to an invoice or sales receipt in QuickBooks Online.
