Labor pulls time entries from Homebase and Toast and applies them to the event they belong to, so the hours your staff actually worked show up as a real cost line against that show instead of sitting in a separate payroll report.
For venues running settlement day of show or the morning after, that means labor cost is already sitting next to the rest of the event's numbers. No re-keying hours, no cross-referencing two systems to figure out what a night actually cost to staff.
