Show Time Periods on Reports
The report you need is a Sessions Sales Report (93). You will need to check the session times in your maintenance settings. Select the Maintenance Page and choose the Setting button. Select Session Times on the left of the screen. Check that the session times are correct. The below example starts reporting any purchases from 5am through until midnight.
If your session sales report is lower than your reconciliation or end of day then it will likely be due to the session timings not covering the entire service time (or a purchase has been put through after service time).
Now go to the Report page and select Financial. Under the End of Day Section choose the Sessions Sales Report code 93.
