Geofenced Time Clock: How GPS Clock-In Works for Contractors

If you've looked into tracking crew hours, you've seen the term "geofenced time clock." It sounds technical, but the idea is dead simple — and it's the single best way to make sure you're only paying for time your crew actually spent on the job. Here's how it works, in plain English.

What a geofenced time clock is

A geofence is just an invisible circle drawn around a location — your job site. A geofenced time clock lets an employee clock in only when their phone is inside that circle. Stand on the site, the clock starts. Sit in the truck down the block or at home, and it won't. No honor system, no guessing.

How GPS clock-in actually works

• You set the site. Drop a pin on the job site and choose a radius that fits it.
• They tap clock in. The app checks the phone's GPS location at that moment.
• Inside the circle? The clock starts and the shift is stamped with the site and time.
• Outside it? Clock-in is blocked — so there's nothing to dispute later.

Why it matters for contractors

Early clock-ins and "I was there at 8" hours are the quiet leaks in every crew's payroll. A geofenced clock closes them without you having to police anyone. The honest crew member doesn't notice a thing; the padded minutes simply disappear. And when a paycheque is ever questioned, the location-stamped record settles it.

"But isn't that tracking my guys?"

Fair question — and the answer depends on the app. A good one only reads location at the moment of clocking in or out, not all day in the background. That means:

• No background tracking — you're not following anyone around the city.
• No battery drain — it's a single check, not a constant one.
• Just the facts you need — were they on site when they clocked in? Yes or no.

That's exactly how Signa App works: location is checked only at clock-in to confirm presence, and that's it.

FAQ

What is a geofenced time clock?

It lets employees clock in only when they're physically inside a job site's set radius. Outside that area, the clock won't start.

Does GPS clock-in drain the phone battery?

Not when it's done right. Signa App checks location only at the moment of clocking in or out — not continuously — so there's no ongoing drain or tracking.

Is a geofenced time clock accurate?

Phone GPS is accurate to a few metres — plenty to tell the job site from the parking lot. You set the radius to fit each site.
