Geofencing is a virtual boundary drawn around a work location. A geofenced time clock checks a phone's location when someone clocks in or out and confirms they are inside that boundary. For a staffing agency, it is how you know a Crew Member was actually at the client's site, without anyone from your office being there.
How does a geofenced time clock work?
A geofence time clock compares the phone's location with a boundary you set around the job site, at the moment of clock-in and clock-out. It is a check at two points in the shift, not continuous tracking.
- 1You set the boundary
The site address plus a radius around it, wide enough to cover the entrance and the place Crew Members actually arrive.
- 2The Crew Member clocks in on their phone
The app reads the phone's location at that moment.
- 3The location is checked against the boundary
Inside the fence, the clock-in is recorded with its coordinates. What happens outside it depends on the system and how it is configured.
- 4The same check runs at clock-out
Both punches land on the timesheet with the location attached, so the hours carry their own proof.
Why do staffing agencies use geofencing?
Staffing agencies use geofencing because they bill for hours worked at sites they do not manage and rarely visit. A direct employer can see who walked through the door. An agency with Crew Members spread across a warehouse, three hotels and a Saturday event cannot, and it is the agency that answers for the hours when a client questions an invoice.
The problems it addresses are specific: a client disputing that someone was on site, a paper sign-in sheet filled in at the end of the day, one Crew Member clocking in for a friend who is still in the car (buddy punching), and a no-show that nobody notices until the client calls.
| Paper sign-in sheet | Phone clock-in, no location | Geofenced clock-in | |
|---|---|---|---|
| Proves the time | No, written by hand | Yes | Yes |
| Proves the place | No | No | Yes |
| Proves the person | A signature, easily copied | No | Only when paired with a photo |
| When you find out about a no-show | End of day, or when the client calls | When the punch does not arrive | When the punch does not arrive |
Where agencies get geofencing wrong
Most geofencing problems are radius problems, not technology problems.
- A fence drawn around the address, not the site. On a stadium, a festival ground or a distribution center, the street address can sit hundreds of yards from where Crew Members report. Too tight a radius produces a stream of failed clock-ins, supervisors start overriding every one, and the fence stops meaning anything.
- A fence so wide it proves nothing. A radius that includes the coffee shop down the road answers the wrong question.
- No fallback for sites where phones are not allowed. Clean rooms, some healthcare units and secure facilities need a kiosk or supervisor clock-in, planned before the first shift rather than discovered on it.
- Not telling Crew Members what is captured. Say plainly that location is checked at clock-in and clock-out, not tracked through the shift. Some states, including New York, require written notice before any electronic monitoring of employees, so check the rules where your Crew Members work. This is general information, not legal advice.
A good starting radius covers the entrance and the parking area Crew Members use. Test it with one real clock-in before the first shift, and widen it for large or spread-out sites rather than switching the check off.
How NextCrew handles geofenced clock-in
NextCrew's mobile app is a time clock app with geofencing: it verifies the Crew Member is at the job site, and records GPS coordinates and a photo at every clock-in and clock-out. The photo is what closes the gap location alone leaves open: it shows who clocked in, not just that a phone was there.
- A configurable radius, so a warehouse and a festival site do not have to share one setting.
- Three ways to clock in, one timesheet. Mobile, an on-site kiosk from an approved network, or supervisor entry for sites where phones are not practical. All three land on the same timesheet.
- A live view of today's shifts. Daily Pulse shows who is confirmed, clocked in, on site, running late or a no-show, with check-in times, photos and locations, and sends late alerts before the client notices.
When a client questions an invoice, the answer is already on the timesheet: the time, the place and the person. See how it fits into timesheet management for staffing agencies.
