Field Service Software for Dispatch, Mobility and Proof of Work
Custom field service software for HVAC, elevator, IT installation and industrial maintenance companies. It links a dispatch board, route optimization, an offline-first technician app and van inventory into one workflow — from inbound call to signed work order and on-site invoice, with no paper and no "let me call him to ask where he is".
What the field service software covers
Dispatch board
Drag-and-drop scheduling by technician, day and hour, color-coded by priority and SLA. See a full week on one screen and reassign jobs with a single drag.
Route optimization
The algorithm orders the day by real distance and traffic; GPS proximity routing suggests the closest technician the moment an emergency ticket lands.
Offline-first technician app
The mobile app works without signal — basements, elevator shafts, industrial sites. Data syncs the moment connectivity returns, with zero lost reports.
Knowledge base for SOPs
Schematics, manuals and SOPs attached to each equipment model. The technician opens them straight from the ticket, not from a buried email or Drive folder.
Photos and signature as proof of work
Before/after photos, customer e-signature and an automatic protocol PDF. "It is not fixed" disputes end with a shared link, not a phone call.
Van inventory and on-site invoicing
Spare parts tracked per van; parts used on site are written off automatically and roll into the invoice the customer signs on the technician's phone.
Who it fits
HVAC service companies
Seasonal peaks, scheduled preventive maintenance, emergency repairs. The system automates annual contracts and never misses a planned visit, even at 200+ active accounts.
Elevator service firms
Monthly building inspections, 24/7 breakdowns, regulatory protocols. Routes plan by proximity, and each elevator's full history is two taps away for the technician.
IT installation and industrial maintenance
Multi-day installs, two- and three-person crews, specialty tools. The system tracks which site needs which resource so no technician arrives without the right cable or module.
How we build it
We do not resell SaaS. We build your own field service software on a proven stack: PostgreSQL for data, Node.js or .NET for business logic, React/Next.js for the dispatch board and React Native for the technician app. REST APIs and webhooks open the system to ERP, accounting and a B2B portal.
We start with a day in the field — riding with a technician, watching how a ticket lands and what gets scribbled on paper. From that map we lock the MVP scope: work orders, dispatch board, mobile app and proof of work. Route optimization and van inventory ship in phase two.
We connect the task management system to your phone system for automatic ticket creation, to the sales rep mobile app for upsell, and to Google Maps or Waze SDK for navigation.
We integrate with your accounting software, courier APIs for parts replenishment, e-signature for the protocol and the tax authority for electronic invoicing. See how we approach mobile app development with offline-first sync.
Go-live happens in stages: one crew for a two-week pilot, then the whole company. After go-live we stay on an SLA-backed support contract with a fixed monthly budget.
Why Saitami for your field service software
Completed jobs per day
Average uplift in jobs completed per technician per day three months after go-live — real data from HVAC and elevator deployments.
Travel time
Achieved through GPS proximity routing and clustering visits by district instead of random ordering in spreadsheets or paper schedules.
Starting investment
Fixed price for the MVP phase. No per-technician licensing, no hidden subscription. You own the field service software outright.
Field service software often runs alongside custom software development for back-office modules. See also our mobile app development service with full offline-first architecture for field crews.
Frequently Asked Questions
How long does field service software implementation take?
Field service software implementation typically takes between 6 and 12 weeks for the first productive phase. A small operation with 3-5 technicians goes live in 6-8 weeks. A mid-size company with 15-30 technicians, a dispatcher and accounting integration lands closer to 10-12 weeks. We never do a big-bang rollout — a pilot crew runs first.
Does the mobile app work without internet?
The mobile app is offline-first — the technician opens the ticket, writes a report, takes photos and captures the customer signature with no signal. Data syncs automatically the moment connectivity returns, with no lost reports. This matters in elevator shafts, basements and industrial sites where GSM coverage is unreliable.
Does it integrate with accounting software?
The system integrates with Microinvest, Plus Minus, Ajour, Business Navigator and SAP Business One via API or file exchange. The invoice signed on site flows automatically into accounting, and parts used from the van are written off from inventory. You keep your accounting tool — the field service module runs operations.
How much does field service software cost?
Field service software starts from €5,200 for an MVP rollout in a small operation with 3-5 technicians and typically lands between €14,000 and €32,000 for a mid-size company with route optimization, van inventory and accounting integration. Pricing is fixed against the agreed scope, paid in milestones, with no per-user fees.
