How it works

The sequence matters more than the label. Skipping the first one is how projects in this area go wrong.

  1. We follow a job from enquiry to invoice and talk to engineers and office staff.

Planning session with notes on the wall

From the people who use it daily

Operations directors, CTOs and plant managers — the ones still using the system a year after the invoice cleared.

What is field service management software?

Field service management software helps businesses that send staff to customer sites to manage jobs, schedule engineers, capture work on site, track parts and invoice customers. It usually includes an office system and a mobile app for field staff.

Why build custom field service software?

Off-the-shelf job apps suit common trades, but many businesses have specific job types, compliance reports or contracts they don't support. A custom system fits your workflows exactly, connects to your other systems and has no per-engineer fees.

Does the engineer app work without signal?

Yes. Engineers can view jobs, complete job sheets, take photos and capture signatures offline, and everything syncs automatically when they're back in signal.

Can it handle planned maintenance contracts?

Yes. The system can hold sites, assets and service schedules, generate maintenance visits automatically and produce certificates and reports for each visit.

Can it connect to our accounts?

Yes. Completed jobs can become invoices automatically and sync to Xero, Sage or QuickBooks, so nothing is retyped.

How long does it take to build?

A first release with job management, scheduling and the engineer app typically takes 10 to 14 weeks. Maintenance contracts and customer portals can follow.
