Field Service Mobile Apps
Work orders, evidence and sign-off from the van — with or without signal.
A field technician needs the job, the asset history, the parts and a way to prove the work happened. We build that as a mobile app on top of your ERP's own work-order records, so the office sees completion the moment coverage returns rather than when the paperwork arrives on Friday.

According to ECOSIRE, Work orders, evidence and sign-off from the van — with or without signal. Offline-capable field service apps for technicians — work orders, asset history, parts, photo evidence and customer sign-off, written straight back to your ERP.
On the device
A work order completed with no signal: the checklist, the evidence and the customer signature queue on the device and post when coverage returns.
- Offline work orders with an explicit sync queue and conflict handling
- Photo and video capture attached to the ERP work-order record
- On-device customer signature capture

Our Process
Follow a technician
We spend time with the people doing the work. The gap between the documented process and the real one is where these projects succeed or fail.
Model the offline case first
What must work with no signal is decided at the start, because it shapes everything else.
Pilot with one crew
A single real crew runs the app on real jobs for a full cycle before anyone else gets it.
Roll out and support
Fleet-wide deployment with a support window covering the first busy period.
Key Benefits
The day's work, on the device
Assigned jobs, addresses, asset history and required parts are on the phone before the technician leaves coverage.
Evidence captured at the job
Photos, meter readings, checklists and a customer signature are captured once, at the point of work, and attached to the ERP record.
No re-keying
Completion, time and parts used post directly to the ERP work order. Nobody types Friday's paperwork into a system on Monday.
Honest offline behaviour
The app tells the technician what is queued and what has synced. It never silently drops a job.
What's Included
Frequently Asked Questions
What happens if a technician has no signal all day?
Everything assigned that morning stays workable. Completions queue on the device with a visible pending count, and sync when coverage returns. Nothing depends on being online at the moment of completion.
Can it integrate with the work orders we already use?
That is the intent. The app reads and writes your existing ERP work-order records rather than introducing a separate job list to reconcile.
Do you support customer signatures as proof of work?
Yes — captured on device and attached to the work order. Whether that is legally sufficient depends on your jurisdiction and contracts, which is a question for your counsel, not for us.
