Hello there, @WendytheArchitect.

I'm here to share with you the screenshot of the report that was presented by my peer above.

The report shared above is the Transaction List by Customer, wherein it shows the invoice and the payments of the customer. It looks like this when you pull it up: 

If you want to see the payments only, you may customize the transaction type of the report to Payment, so only the payments of the invoices will show up. You can follow the instructions given by my peer Charies_M on this thread on how to do that.

On the other hand, when it comes to the invoice number that is associated with the payment, adding them to the memo field is the workaround that we have since the number that will show up in the NUM column is the reference number of the payment. 

Know that the single report that you'd to like run which easily shows payments received and their corresponding invoice numbers isn't an option to us. I'd encourage you to check out our Firm of the Future site regularly, to be updated with our product road-maps.

To give you more details about the different reports that you can pull up in QBDT together with how to customize them, please check out this link: Available reports in QuickBooks Desktop.

Let me know if you have any other questions or concerns. I'll be right here to help. Take care!
