Know Your Calendar
Before anything else, know the dates. Run date, cutoff date, and any holidays that shift them. A payroll calendar that's mapped ahead of time means nobody finds out the morning of that the cutoff was actually yesterday.
Map the full year if you can — pay dates, holiday shifts, and quarter-end obligations — so the calendar drives the routine instead of the other way around.
- Run date and cutoff date for this cycle
- Holidays that shift either date
- Quarter-end and year-end dates flagged
