Field service management (FSM) is how a company organises work done at its clients' sites: who goes where, when, with what information, and how the work is recorded, signed off and billed. Large companies run it with enterprise systems and a dispatch team. Most service companies in Singapore run it with WhatsApp groups, spreadsheets and paper job sheets, and that works until the team or the client list grows.
What Field Service Management Covers
- Taking requests: calls, WhatsApp messages, emails and fault reports
- Scheduling jobs and assigning technicians
- Giving technicians the job details they need on site
- Recording the work: forms, checklists, readings and photos
- Getting the client to sign off before the technician leaves
- Sending the service report to the client
- Quoting and invoicing
- Maintenance contracts and recurring visits
- Keeping a history for every client, site and piece of equipment
Signs You Have Outgrown WhatsApp and Spreadsheets
- You cannot answer "when did we last service this unit?" without scrolling through chats.
- Job sheets come back days after the job, so invoices go out late.
- A missed contract visit is discovered by the client, not by you.
- New technicians learn the job by asking questions in the group chat.
- Reports look different depending on which technician wrote them.
The Parts That Matter Most
Jobs and Scheduling
Every job needs a number, a client, a site, a date and time, and one or more assigned technicians, visible to both the office and the technician. Reminders before the job and a clear view of late or missed jobs stop small slips from turning into complaints.
Technician Access
Field staff need job details on their phone without a desk and without a password they will forget. This is where most job apps fail, which is why QR code access has become popular: each technician scans a personal code and their jobs open.
Service Reports and Sign-Off
Each type of job needs its own form, with the checks and readings that matter for that work, plus photos and the client's signature before the technician leaves. The report should reach the client the same day, ideally before the technician has driven off.
Recurring Work and Equipment
If you sell maintenance contracts, you need a register of the equipment you look after, schedules that create visits automatically, and a service history per unit you can show the client at renewal.
Client Communication
Clients want three things without having to call: the report, the date of the next visit, and an easy way to report a fault. Report links, client portals and QR fault reporting cover all three.
Quotes and Invoices
Once a job is signed off, invoicing should not wait for paperwork. Some field service tools include quotations and invoices; others leave that to your accounting software.
How to Choose Field Service Software Without Overbuying
- Start with the problem that costs you most: late reports, missed visits or lost job sheets.
- Check that technicians can use it on the phones they already have.
- Look at what your clients receive. Is it your brand, or the software vendor's?
- Compare per-company pricing with per-technician pricing; per-user prices make every new hire more expensive.
- Run it on real jobs for a week. A free trial tells you more than any demo.
- Ignore features you will not use in the first year.
