You can customize your own timesheet period in iBE either weekly (starting on any day of the week) or a custom period such as two weeks, monthly, weekly with splits at month-end for billing or bi-monthly (1-15, 16 to last day of month). If you modify the timesheet period configured against a work-schedule, or change the work-schedule an employee or contractor is assigned after some timesheets have been created iBE now scans the current active timesheet period to see if there are any pre-existing timesheets overlapping the current period, and automatically cuts short or trims down the current timesheet period to avoid any timesheets overlapping with each other. This means you can modify work schedules or timesheet period definitions after entering timesheets in the system without worrying about a conflict between new and old timesheet data
