Good day, @Vitan.
I can help you run a report that shows the total money receive including the discounts and sales tax.
- Click Customers.
- Choose Customer Center.
- Select the Transactions tab.
- Go to Received Payments .
- For the Filter, select Checks.
- Click Run Reports button and select View as a Report.
- Once the report is ready, you can customize it.
That should do it. Keep me posted if there's anything else you need about reports. Just mention my name or add a message below. Have a good one.
