How to generate a report of CASH Payment received ?

Hi info1801, 

Welcome to the Community! QuickBooks offers a variety of reports that help you bring your finances into perspective. I'll be happy to help so you're on the right track with completing your work with ease. 

Based on what you've described, I recommend running the Invoices and Payments Received report. This report displays the payments you've received and the payments that go with them . You can learn more about customizing this report by checking out this helpful article here. 

Let me know if this info helps. I'll be a message away in case you need additional support.
