Accountant asking for a list of Revenue for the year by Customer.

SUGGESTED

Sage 100 Contractor. Where would I pull this type of report from?  If I go into the 3-6 and choose a specific client and click on the payment button those payment total for that year are different than if I run the Report 3-1-2 78.  So where do I find a report for a list of revenue for the year by customer?  (hopefully a custom report is not necessary)
