Key takeaways
- The technician's mobile app decides whether the system succeeds
- Capture spares used on every job, or warranty and stock numbers will never reconcile
- Offline working is a firm requirement
You install solar systems, service lifts, repair medical equipment or maintain air conditioning across a city. Complaints arrive on the phone, the coordinator posts jobs in a WhatsApp group, and technicians reply "done" when they finish. It works until you have more than ten technicians, a warranty claim you cannot prove, or a large customer who wants service reports against an annual maintenance contract.
Quick answer
Field service software should take a complaint or scheduled visit, assign it to the right technician, give that technician everything they need on a phone app, and record what was done, which parts were used and the customer's sign off. Packaged options such as Zoho FSM, Salesforce Field Service and several Indian products cover the common cases. Custom development makes sense when your jobs involve detailed checklists, regulatory reports or tight integration with your own product data.
What the system must do
- Job intake. From a phone call, WhatsApp, a customer portal or a scheduled AMC visit, every job gets a number, a customer, an address and an equipment record.
- Assignment. By skill, location and availability, with the coordinator able to override. Automatic route optimisation helps large teams, but a map view with technician locations is enough for most.
- The technician app. Job details, equipment history, previous visits, a checklist for the job type, photo capture, parts used and a customer signature or OTP confirmation.
- Spares control. Each technician's van or bag stock, parts issued from the store, parts consumed per job and returns of faulty parts.
- Closure and billing. Service report sent to the customer automatically, with chargeable jobs flowing to invoicing.
- Contracts and warranty. AMC and warranty terms linked to equipment, so the coordinator knows instantly whether a visit is chargeable.
The technician app decides everything
If technicians find the app slower than a WhatsApp message, they will fill it in at the end of the day from memory, or not at all. Design for them.
- Works offline in basements, plant rooms and rural sites, syncing later.
- Large buttons, few required fields, and yes or no checklists.
- Available in the languages your technicians read. Hindi, Gujarati, Marathi or Tamil may matter more than any feature.
- Photos before and after, attached automatically to the job.
- Runs on the mid range Android phones your team actually carries.
Sit with three technicians for a day before you choose a product. Watch where they lose time. That is what the app needs to fix.
Spares are where money leaks
Most field service businesses cannot say what spares were used on which job. That leads to stock that never reconciles, warranty claims to manufacturers that cannot be supported, and free parts given to customers outside warranty.
Make parts used a required step at job closure, scanned or picked from a list. Issue parts to technicians against their name, and reconcile van stock monthly. Faulty parts returned for warranty should carry the job number.
Measures worth tracking
- First time fix rate: jobs closed on the first visit.
- Response time against what the contract or warranty promises.
- Repeat complaints on the same equipment within 30 days.
- Jobs per technician per day, read alongside travel distance.
- Spares consumption per job type.
Do not turn these into league tables on day one. Technicians who feel watched start closing jobs early. Use the numbers to find problems, such as a part that fails often or an area with too few technicians.
Rolling it out
Start with one branch or one product line. Load the equipment base for those customers, even if it is incomplete, and fill gaps as technicians visit. Run for a month with the coordinator checking closures daily. Then extend.
Connect to your ERP or Tally for spares stock and invoicing early, even with a simple nightly sync. A field service system that keeps its own separate inventory will drift within weeks.
For a team of 20 to 100 technicians, a packaged system is usually live in three to five weeks. A custom system with your own checklists and reports typically takes six to eight weeks for a first version, plus time for the team to adjust.
