Another app nobody opens
Technicians push back on installing and learning one more app, and every new hire means another round of setup.
WhatsApp FSM Nothing to install
WhatsApp field service management software
Your technicians receive work orders, check in, fill checklists, send before and after photos and get the client's sign-off in WhatsApp, with no app to install. Every update lands on the job record in Zentid Manage, so the service coordinator sees it without a phone call.
Sites with no signal? The Zentid Field app does the same jobs and works offline.

RemindersBefore each job
Nothing to install
Technicians use the WhatsApp already on their phone.
Two ways to work
WhatsApp, or the Zentid Field app where signal drops.
One job record
Every update lands on the work order in Zentid Manage.
The problem
Your field team does not need another app
Most service teams already run the field on WhatsApp groups and phone calls. None of it reaches the job record, so service coordinators spend the day chasing updates.
Constant follow-up calls
Service coordinators phone technicians to ask where they are, whether the job is done and which spare parts were used.
Missed check-ins
Arrival and departure times are not recorded, so attendance and timesheets get pieced together later.
Photos lost in group chats
Photos, notes and sign-offs sit in a busy WhatsApp group instead of on the work order.
Reports that come back late
Paper job sheets arrive days later, the service coordinator retypes them, and the invoice waits for the report.
In the chat
What technicians do in WhatsApp
Every action below is saved against the work order in Zentid Manage.
The day's schedule
All of today's PPM visits and call-outs arrive in one message with I'm Ready and Not Ready buttons.
Reminders and quick checks
A reminder 30 minutes before each job (you can change the timing), and one-tap questions like whether special equipment is needed.
Work order details
The site, the scope of work and what the technician needs to bring.
Check in and check out
Attendance and timesheets are recorded in Zentid Manage.
Job checklists
The technician works through the checklist step by step in the chat.
Before and after photos
Before and after photos and notes sent in the chat attach to the work order.
Spare parts by barcode
Photograph the spare part barcode and send it with a quantity.
Client sign-off
A signature link goes to the client, who signs on their own phone.
Close the job
The technician marks the work order complete from the same chat.
How it works
From assignment to sign-off in one chat
The service coordinator schedules the job
The work order is created in Zentid Manage, or comes from an AMC contract as a scheduled PPM visit. The Scheduling agent can propose a technician, and the service coordinator approves.
The technician gets it on WhatsApp
The job arrives in the morning schedule, with a reminder 30 minutes before the visit.
Check in on site
One reply records the arrival time against the job.
Do the work
Checklist, before and after photos, notes and spare parts used, all sent in the same chat.
Client signs, job closes
The client signs through a link, and the technician checks out.
The service coordinator sees it in Zentid Manage
The service report is ready in English or Arabic. The Post service agent drafts the report and the invoice for a manager to approve.
Mobile and offline
Which field service apps offer the best mobile support and offline capabilities?
Check two things: what the technician has to install, and what happens when there is no signal. With Zentid, technicians run jobs in WhatsApp with nothing to install. WhatsApp needs signal, so for basements, plant rooms and remote sites the Zentid Field app works offline and syncs when the connection returns. Same jobs, same data, same system.
For PPM visits, call-outs, subcontractors and new crews.
- Nothing to install or update
- No storage needed on the phone
- Needs a live connection
Zentid Field app
For sites where signal drops, and technicians who prefer an app.
- Works offline, syncs when the connection returns
- Same work orders, checklists, before and after photos and sign-off
- On iPhone and Android
