Frequently asked questions
How does it know who submitted?
It compares your team roster against the list of timesheets submitted this week (from a Google Sheet, Harvest, Clockify, or your PM tool). Anyone on the roster without a submission gets the reminder — so people who already did their timesheet aren't nagged.
Why DM instead of a channel blast?
A public 'submit your timesheets' message gets ignored; a personal 'you haven't submitted yet' gets action. DMing only the non-submitters keeps it relevant and avoids annoying the punctual majority.
