How Guardian Security Eliminated All Client Billing Disputes
An Atlanta security firm with 28 guards across 12 client sites was losing contracts due to billing disputes. GPS-verified Timedox reports changed everything.
The Company
Guardian Security Services provides commercial security and mobile patrol services across the greater Atlanta area. They manage 28 guards deployed to 12 client sites including corporate campuses, retail complexes, and residential communities.
James Washington runs operations. His primary challenge: clients demanded proof that guards were on-site for every contracted hour, and Guardian had no way to provide it beyond handwritten logs.
"One in four invoices was getting disputed. We were losing clients over trust."
Guardian relied on paper sign-in sheets at each client site. Guards filled them out manually, and there was no way to verify accuracy. Late arrivals were reported as on-time. Early departures went unnoticed.
Clients had started requesting detailed attendance proof with their invoices. When Guardian couldn't provide it, disputes followed. Two major contracts were lost in a single quarter.
"Our guards were doing the work. We just couldn't prove it. Every disputed invoice was a conversation about trust, and we were losing that conversation."

Why they chose Timedox
James needed GPS-verified proof that guards were at the right site at the right time. Timedox's mobile app with GPS verification provided exactly that.
"Every clock-in now has GPS coordinates attached. I can pull a report showing exactly when each guard arrived and left each site. When clients ask for proof, I just export the report. Conversation over."
Geofencing added another layer: guards can only clock in when they're physically within the defined zone of their assigned site. Attempted clock-ins from outside the fence are flagged immediately.

Mobile app deployed to all 28 guards
Each guard installed the Timedox app on their phone. Geofences were set up for all 12 client sites. Training: 10 minutes per guard.
First GPS-verified reports generated
James pulled the first week's data: every guard, every site, every clock-in/out with GPS proof. He sent the reports to his three most skeptical clients.
Billing disputes dropped to zero
With GPS-verified reports attached to every invoice, not a single client disputed their bill. The two clients Guardian had lost? One of them called back.
Coverage gaps eliminated
Real-time monitoring showed James exactly when shift handoffs were happening. He identified and closed an 18-minute average gap that had been exposing clients.
New contracts won on transparency
Guardian started including 'GPS-verified attendance reports' in their sales proposals. They won 3 new contracts specifically because of the transparency Timedox provided.

"Our clients love the GPS-verified reports. When they ask 'were your guards there?', I don't have to argue anymore. I just show them the data. We went from losing contracts to winning them because of Timedox."
