Field service software for generators & upsGenerator and UPS maintenance software for AMC visits, load tests and breakdowns
Hundreds of generators and UPS systems under contract, each with its own service dates, running hours and parts. FieldN plans every visit, records every test and never lets a contract lapse.
Quick answer
FieldN is maintenance software for companies that service diesel generators, UPS systems, batteries and power backup for buildings, hospitals, data centres, telecom sites and factories. Every generator or UPS is an asset with make, model, serial, rating and service history; AMC contracts plan the quarterly or monthly visits and raise the invoices; technicians fill a service checklist on the phone — oil, filters, coolant, battery, load test readings — with photos and the customer's signature; breakdown calls are dispatched to the nearest technician with the right skill.

What slows a generator and UPS service company down — and how FieldN fixes it
Service visits slip past their date
Each AMC plans its visits for the year — monthly, quarterly, half-yearly — and they appear on the dispatch board in time.
No single record per machine
Every generator and UPS is an asset with serial, rating, install date, running hours and every visit, test and part fitted.
Service reports differ from technician to technician
One checklist for all: oil and filter change, coolant, belts, battery voltage, load test readings, alarms — with photos and signature, printed on the job card.
Breakdown calls jump the queue
Emergency calls go to the nearest technician with generator skill; the customer gets "technician on the way" updates.
Filters and batteries run out
Parts used per visit come off stock and go on the invoice; reorder points keep the common filters and batteries in the store.
Contracts end without a renewal
Renewal reminders go to you and the customer before the contract ends, with the renewal quote ready.
Three apps, one system: a booking portal and app for your customers, a technician app for Android and iPhone, and the office back end for dispatch, contracts, stock, invoices and HR. See all FieldN features.
A generator AMC visit in FieldN, start to finish
- Contract: the AMC lists each generator and UPS covered, the visit frequency and the contract invoices.
- Plan: visits appear on the board in the right month; the office assigns the technician or lets smart dispatch suggest one.
- On site: the technician checks in, fills the service checklist with readings and photos, records parts used and any fault found.
- Close: the customer signs, the service report PDF goes out, and parts outside the contract are invoiced.
- Renewal: before the contract ends, FieldN reminds you and the customer and the renewal is invoiced.

Generators & UPS software — frequently asked questions
What is the best software for a generator service company?

Can FieldN keep running hours and service history per generator?
Yes. Each generator or UPS is an asset with manufacturer, model, serial, warranty and every visit, reading and part fitted. Running hours are a field on the checklist.

Yes. Build the service checklist with voltage, frequency, load percentage and any other readings; the technician fills it on the phone and it prints on the service report.
Does FieldN handle generator AMC contracts?
