AMC Management: Contracts, Coverage, Renewals and Billing
Annual maintenance contracts are steady revenue, but only if you know which machine is covered, for what, and until when. A practical guide to running AMCs without leaks.
How geo-fenced attendance works, when to use mobile Day-In or biometrics, how to roll it out and how to respect employee privacy.

Attendance is easy to manage when everyone walks through the same office door. It gets difficult when half your team starts the day at a dealer’s shop in Rajkot, a hospital in Pune or a solar site outside Jaipur. Paper registers and “I’ve reached” messages cannot be checked, proxy attendance goes unnoticed, and HR spends the end of every month reconciling sheets for payroll. Geo-fenced attendance solves this by letting field staff mark attendance from their phone, but only from places the company has allowed. This guide explains how it works, how it compares with biometric devices, how to roll it out, and how to handle the policy and privacy side properly.
A geo-fence is a virtual boundary drawn around a location, usually a point on the map with a radius. When an employee marks attendance in the mobile app, the app reads the phone’s location and checks whether it falls inside an allowed geo-fence. If it does, attendance is recorded. If it does not, the app refuses it or flags it, depending on how you configure the rules.
In practice, a field team’s day looks like this:
The geo-fence radius needs some thought. Too small and phone location drift inside a building will reject genuine attendance. Too large and the boundary stops meaning anything. Start with a radius that covers the premises comfortably, test it on different phones, and adjust.
Biometric devices are reliable for people who come to a fixed office or factory. They are of little use for staff whose first stop is a customer in another city. Most Indian companies with field teams need both, and the question is who uses which.
| Mobile Day-In with geo-fence | Biometric device | |
|---|---|---|
| Best for | Sales reps, service engineers, site crews, anyone who starts the day outside the office | Office, factory and warehouse staff at a fixed location |
| Proof of presence | Phone location inside an allowed boundary | Fingerprint or face at the device |
| Hardware | Employee’s smartphone | A device at each premises |
| Weak points | Poor GPS signal, phones without location enabled | No coverage for people away from the premises |
| Links to field work | Can start the day’s visit plan directly | Usually separate from field activity |
The important thing is that both feed one attendance record. If biometric punches sit in one system and mobile Day-Ins in another, HR is back to merging spreadsheets before payroll.
A rushed rollout creates resistance. A planned one usually settles in within a few payroll cycles. Use this checklist:
Expect a few common problems during the pilot:
Location data is personal. Employees accept location-based attendance far more readily when the company is clear and fair about how it is used. The following are good practices rather than legal advice; check your own obligations under applicable law and your company policy.
The aim is verified attendance during working hours, not surveillance. Stating that clearly in your policy does more for adoption than any feature.
In Effezient, employees mark Day-In and Day-Out from the mobile app, and geo-fenced attendance is accepted only inside the configured geo-fence. Office punches from biometric devices sync into the same attendance record, and a simple red or green status shows whether today’s attendance is marked. Leave types, accrual and holidays follow your company policy, with manager approvals in the app.
For field staff, the Day-In opens the employee’s approved tour plan for the day, so attendance and visits are connected. Attendance and approved leave then flow straight into HRMS and payroll, so HR does not re-enter anything at month end.
Only if home is configured as an allowed location. Otherwise, attendance outside the geo-fence is not accepted, which is what stops proxy attendance.
No. Keep biometrics for office and factory staff and use mobile Day-In for field staff. What matters is that both feed the same attendance record.
It should not. Good practice is to use location only during working hours and only for attendance and work verification, and to say so clearly in your policy.
It depends on team size and how many locations you have. A pilot of about one payroll cycle with one team, followed by a phased rollout, is a sensible approach for most companies.
