AccountEdge makes it easy to review your sales.
If you want to see sales by customer, print:
Sales [Customer Summary] report
To track what items (from your Items List) you sold to a customer, print:
Sales [Customer Detail] report
To spot customer sales trends over a period of time, run these two reports:
Analyze Sales [Customer - FY Comparison] report
Analyze Sales [Customer Spreadsheet] report
Note: Once you settle on the list of reports you like to run every month, consider creating a report batch for them. Refer to What's a Report Batch? for more information.
