The verdict in three sentences
A custom field service management platform costs in 2026 between 62,000 and 125,000 SGD and ships in 4 to 6 months, technician mobile app included. The real gain is not cosmetic: -25 % travel thanks to schedule optimization and +15 % billing thanks to on-site time capture and client signature. Custom is justified when off-the-shelf SaaS does not fit your processes: otherwise, a subscription is enough.
Custom or off-the-shelf SaaS: how to decide
The first decision is not budget but fit. A generic SaaS costs 35 to 85 SGD/technician/month; custom is a one-time investment amortized over several years.
| Criterion | Off-the-shelf SaaS | Custom platform |
|---|---|---|
| Entry cost | 35 - 85 SGD/technician/month | 62,000 - 125,000 SGD once |
| Process fit | Standard, needs adapting | 100 % on your workflows |
| Setup time | 2 - 6 weeks | 4 - 6 months |
| Cost at 30 techs/3 years | 38,000 - 92,000 SGD | 62,000 - 125,000 SGD + maintenance |
| Data ownership | With the vendor | With you |
| Specific integrations | Limited | Custom (ERP, accounting) |
Below 15 technicians and with no specific need, SaaS wins. Beyond that, or with atypical processes, custom becomes profitable.
What the custom budget covers
| Module | 2026 range | Business impact |
|---|---|---|
| Scheduling + smart dispatch | 14,000 - 25,000 SGD | -25 % travel |
| Technician mobile app (iOS/Android) | 19,000 - 36,000 SGD | Real-time field capture |
| Intervention reports + photos | 8,000 - 15,000 SGD | Proof and quality |
| On-site client signature | 4,000 - 8,000 SGD | +15 % billing |
| Dashboard + KPIs + exports | 8,000 - 17,000 SGD | Steering |
| ERP / billing integration | 8,000 - 19,000 SGD | Zero double entry |
Mini case study
Nadia, director of an HVAC maintenance company in Singapore, runs 28 technicians and 900 interventions/month. Her custom platform costs 94,000 SGD, delivered in 5 months. Before: 30 % of interventions billed late or forgotten. After: on-site signature and mobile capture recover +15 % billing, roughly 12,000 SGD/month on revenue of 82,000 SGD. Optimized scheduling saves 25 % of travel, about 4 hours/technician/week. Estimated payback in 8 months.
FAQ
Need a professional website?
Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Why a dedicated mobile app rather than a simple web form?
Because technicians work offline (basements, sites without signal) and need the camera, GPS and signature. A native app (19,000 - 36,000 SGD) guarantees reliable field capture, which a web form cannot.
How does the platform actually cut travel by 25 %?
Smart dispatch groups interventions by zone and skill, avoids back-and-forth and prioritizes emergencies. Across 28 technicians, that means thousands of km saved per month.
Can we integrate our existing billing software?
Yes, and it is recommended: ERP/billing integration (8,000 - 19,000 SGD) removes double entry and speeds up collection. It connects via API to most market software.
What is a realistic timeline to go live?
Expect 4 to 6 months: 1 month of scoping, 3 to 4 months of development, then a pilot phase on one team before full rollout.
Should I budget for annual maintenance?
Yes, typically 15 to 20 % of the development cost per year for enhancements, security and support, i.e. about 14,000 to 19,000 SGD/year for a 94,000 SGD project.
