Telephone Timesheets supports a variety of report types. Details on each report type can be found in the Report Types section of the user manual.
Each time a report is run, it creates a record in the Report History section. You can view past reports and re-run past reports from the history section. This is useful if you make changes in the Time Entry log and wish to re-run a payroll report, for example.
It is a best practice to keep an eye on Time Entries regularly and fix up any forgotten check outs, or other issues. Then, when it is time to run payroll reports, your data will be accurate.
