A site supervisor sees a worker sign on, but the wider team may not know who is now on site. SignOnSite users can turn that event into a practical SMS through Mobile Message, such as a notice to a site contact or an operational reminder for the worker. The same approach can send a message when attendance closes, helping people know that a worker has signed off.

SignOnSite offers New Attendance, Attendance Closed and New Site Created triggers. Use New Attendance with Send SMS to notify a nominated recipient when someone signs on, or use Attendance Closed to send a sign-off update. New Site Created can alert an operations contact when a new location is added. The connection is made through Zapier, where you choose the SignOnSite event, map its available fields and select the Mobile Message recipient and message.

This can reduce the need for supervisors to repeat routine updates by phone or message. Keep texts limited to useful site information and avoid treating an SMS as the complete safety record. SignOnSite remains the source for attendance details, while Mobile Message delivers the short notification your team needs.
