How to get a report on customer cash payments?

Thank you for sharing your concerns here in the Community, ebs3.

You can check the transactions made by the customers in QuickBooks Online.

I'll be happy to share some information on how to get the customer's payment report.

Here's how:

1. From the left menu, go to Reports.
2.  Enter Transaction List by Customer on the search box.
3.  Under Report period, choose the date that you want to check.
4. For Rows/columns, choose Customer.
5. Click on Run Report.

You can also record the cash payments made by the customer.

Take care.
