Timesheet Reminders
Managers spend the end of every month nagging for timesheets over Slack and Teams. Sandtime.io reminds people automatically, lets managers approve with one click, and locks past periods - so client billing is never blocked.

How Sandtime.io stops the chasing
Automatic fill-timesheet reminders
Sandtime.io reminds people to fill their timesheet automatically - no manager has to send the message.
Dashboard, email, and popup channels
Choose dashboard, email, popup notifications, or any combination - reminders fit how each team already works.
One-click approvals
Once timesheets are in, managers approve or reject with one click directly from email.
Auto-locking after approval
Approved and past periods lock automatically, so month-end numbers stop moving after billing starts.
Overlap detection built in
Overlapping or implausible entries are flagged before they reach a report or invoice.
Timestamped history
Every reminder, submission, approval, and lock is timestamped, so month-end billing has a clear paper trail.
Who uses timesheet reminders
- Managers who currently chase timesheets manually over Slack or Microsoft Teams
- Agencies and software houses that cannot invoice clients until every timesheet is in
- Finance and payroll teams closing a period who need complete, approved records
- Growing teams where month-end nagging no longer scales
Reminder questions
What do reminders do?
They prompt people to submit hours before the period closes, which is the single change that most reduces hours arriving after an invoice has gone out.
Can people turn reminders off?
Yes. Notification settings can be adjusted to match how your team works, so reminders stay useful rather than becoming noise people filter away.
Do reminders replace approvals?
No. Reminders get hours in on time; approvals decide whether those hours are accepted. They work together and both are free.
Where do reminders arrive?
By email, and Slack notifications are available once an administrator connects Sandtime.io to Slack.
