FSM · Mobile add-on
Field technician app, even with no signal
The workshop in your pocket: everything the job needs, nothing more.
A technician who calls the office for an address, writes parts down in a notebook or loses signal in a basement means a job that slows down. The Essuivi mobile app complements the FSM module: the assignment arrives on the phone and the work is documented on site, even offline.
The assignment arrives with everything needed.
The technician receives the job with the address, time slot, job type and relevant documents. They launch navigation and start the job from the app.
- Address, time slot and job type
- Relevant documents and history attached
- Navigation launched from the app
- Schedule updates received live

No signal? The job goes on.
In a cellar, a boiler room or a dead zone, the app works without a connection. Report, photos, parts and signature are saved on the phone and sync as soon as the signal returns.
- Every step available offline
- Data stored on the phone
- Automatic sync when the signal returns
Photos and installed parts, captured on site.
The technician takes photos and logs the parts used while on the job. The office finds them on the report, and the van stock is updated.
- Before/after photos from the device
- Installed parts picked from the catalog
- Van stock updated automatically
The customer signs on screen, the job is closed.
At the end of the job, the customer signs directly on the technician's phone. The signed report goes up to the office, ready to invoice.
- Customer signature on mobile
- Timestamped signature attached to the report
- Signed report sent to the office
