What is field service management?
Field service management, or FSM, is how a business organises people who work at customers' sites: installing, repairing, inspecting and maintaining equipment. Because those people are away from the office, the business must plan their day, give them the right job information, track what they do and make sure the customer is billed.
Technicians who install air conditioners, maintain solar plants, repair lifts or service generators are all field service workers. Behind each of them is an office that books jobs, sends the right person, orders parts and sends invoices. FSM is the system that connects the two.
Good field service management means the right technician reaches the right job, with the right parts and information, at the right time, and the work is recorded properly.
A simple example to understand it
Meet Pooja, who runs a company in Pune that maintains rooftop solar plants under AMCs. Each morning, her team faces the same questions: which visits are due, who is free, who is closest, which parts are in which van, and which contracts are about to expire.
With field service management in place:
- Planned visits appear automatically from the contracts.
- The dispatcher sees who is free and where each technician is.
- Technicians open the job on their phones with the equipment history.
- Photos, parts used and sign-off are recorded on the spot.
- The office sees job status live and invoices from the record.
Pooja spends less time chasing and more time growing.
The parts of field service management
- Scheduling and dispatch. Matching jobs to technicians by skill, availability and location.
- Mobile access. Giving technicians the job details and a way to record the work.
- Customer and equipment records. Keeping the history of each customer and each machine.
- Parts and inventory. Knowing what is in the warehouse and in the vans.
- Contracts and recurring visits. Managing AMCs, schedules and renewals.
- Tickets and SLAs. Handling requests and response times. See service ticket.
- Invoicing and cost tracking. Billing the customer and seeing what each job cost.
- Reporting. Seeing open jobs, late jobs and performance.
Field service management vs CMMS vs ERP vs CRM
| System | Main question it answers |
|---|---|
| Field service management | Which technician does which job, where and when, and what happened? |
| CMMS | When is each asset due for maintenance? |
| ERP | How do finance, inventory and procurement work across the business? |
| CRM | Who are my customers and what is the status of each sale? |
Many service businesses need parts of all four. The question is which one to start with. If you install and then service equipment, FSM is usually the right place to start.
Common mistakes in field service management
- Scheduling on a whiteboard. It works until it does not, and then nobody can see the whole picture.
- Technicians without job history. They arrive not knowing what was done last time.
- Parts not tracked. Costs and stock stop adding up.
- Contracts in a folder. Renewals and visits get missed.
- Paper that comes back late. Billing waits for the paperwork.
How ZEP360 handles field service management
ZEP360 is built for contractors who service what they install. A dispatch hub shows who is free and where each technician needs to be, and route planning sends the job to the nearest qualified technician by skill and location. Equipment history sits under a barcode for each unit, service cost is tracked per visit, and contract management includes e-signature, per-unit renewals and SLA escalation. Photos, spare parts used and compliance sign-off are captured on site. See more on field service management software.

Frequently Asked Questions
What is field service management?
Field service management is the coordination of work done at customers' sites, including scheduling, dispatching technicians, mobile job updates, parts, contracts and billing. It is often supported by software that connects the office and the field.
What is field service management software?
It is software that handles the full life of a field job: booking, scheduling, dispatch, mobile updates, parts and cost tracking, contracts and invoicing. It gives the office live visibility of the work and gives technicians the information they need.
Who uses field service management?
Companies that send technicians to customer sites use it, including installers, maintenance contractors, HVAC firms, solar service companies, facility teams and equipment service providers.
What is the difference between FSM and a CMMS?
A CMMS focuses on maintenance of assets you own, answering when each asset is due. FSM covers the wider work of serving customers, including dispatch, contracts, customer records and billing. Many service contractors need FSM.
What are the benefits of field service management?
The benefits are fewer wasted trips, faster response, better records, clearer cost per job, fewer missed renewals and easier billing. Customers also see better service because technicians arrive prepared.
How do I know when I need FSM software?
You need FSM software when you cannot see which jobs are open and late without calling around, when parts leave the store without a record, or when renewals live in someone's calendar. At that point, a spreadsheet costs more than it saves.
