Ask how each candidate handles a site that is offline during the event you care about. Without buffering at the edge and replay on reconnect, your discharge data will have holes exactly where the outages were. Expect $70,000 to $150,000 for a first release covering collection, battery health scoring, fuel modelling and ranked triage over 12 to 18 weeks.
Your rectifier vendor's portal will tell you a string is floating at 54.2 volts and perfectly healthy. It will say exactly that on the morning of the day the same string delivers forty minutes against an eight hour rating. Nothing in the telemetry changed. A valve regulated lead acid string does not announce its decline, and the only honest test is a discharge you cannot afford to schedule across a fleet.
That is the risk you are hiring against, and it explains why demos are close to useless here. Every platform looks capable against clean single vendor telemetry in a data centre hall. Your estate is four rectifier families, two generator controller brands, Modbus RTU over a serial to cellular converter at a site with marginal signal, DNP3 at whatever you inherited from a utility partnership, and a handful of locations where the only reliable data path is a technician's phone. The protocol layer is where these projects fail, not the analytics, and almost nobody prices it honestly.
What a site power monitoring development company actually does
Charts of voltage and tank level are the easy quarter of the work.
Collection has to buffer at the edge and replay on reconnect, because backhaul drops precisely when the interesting events happen. Battery health has to be built from your own fleet history rather than from a threshold, which means treating every unplanned mains failure as a free capacity test: record the discharge curve, ambient temperature, load in amps and time to recovery, then trend temperature compensated capacity per string and rank the fleet. Sites in benign grid areas get flagged for a deliberate test precisely because they never discharge, and that small minority is the only crew dispatch worth making.
Fuel needs a consumption model per site in litres per run hour at typical load, so predicted days of autonomy drives the delivery run instead of a calendar. Then reconcile three numbers: modelled burn, delivered litres on the docket, and the tank level step that delivery should have produced. A docket claiming 400 litres into a tank that rose by 220 becomes a ticket, not a paid invoice. And alarms need criticality that only you hold, because a mains fail at a hub carrying twelve downstream sites and a public safety tenant is not the same event as a mains fail at a leaf.
What it really costs in 2026
Bands from Digital Heroes delivery experience across 2,000+ projects, for a fleet of several hundred powered sites.
| Scope | Cost | Timeline |
|---|---|---|
| Edge collection with store and forward, two or three controller families, battery health scoring, fuel burn modelling with delivery reconciliation, criticality ranked triage | $70,000 to $150,000 | 12 to 18 weeks |
| Adding dispatch integration, generator preventive maintenance and spares and battery capital planning | $160,000 to $300,000 | 4 to 7 further months |
| Full platform with tenant service level evidence reporting and a contractor portal | $180,000 to $450,000 | 8 to 14 months total |
| Run, plus a rate per additional controller family | 15% to 20% of build per year | Retainer |
Two costs go missing from most proposals.
A lab unit per controller family. Register maps as documented by the vendor and register maps as implemented in firmware 4.2 are not always the same document, and you find the difference at a live site at two in the morning if you skip this. Each new family is typically one to three weeks including bench work and one site validation. For discontinued hardware, sourcing a lab unit at all can take longer than writing the driver, so raise it during scoping rather than after.
Hardware fitment. Some of your sites cannot report anything useful until a tank sender or a shunt is installed, and that is a field programme with truck rolls attached, not a software line. Decide which sites pay back a sender before the build starts, because the answer changes the scope of the fuel work considerably and it is a capital conversation with a different approver.
Signals of a strong partner
- They raise store and forward before you do. Anyone who has built for outdoor telecom sites knows the telemetry you most need arrives after the link comes back.
- They describe a real state of health method. Temperature compensation, load at time of discharge, trending per string. A voltage threshold with a colour on it is a repackaged alarm.
- They name protocols, vendors, models and transports. Modbus over TCP to a modern controller and Modbus RTU over a cellular converter at a marginal site are different projects.
- They ask who your tenants are. Criticality tiering reflects backhaul topology, service credits and any public safety obligation, and no packaged platform can supply it.
- They propose suppressing alarms above an autonomy threshold. The real failure state is not a missing alarm, it is a queue the network operations centre has learned to filter out.
- They want the fuel reconciliation in release one. It is the fastest measurable return and it needs no analytics beyond arithmetic.
- Your repository, cloud accounts and device credentials, from the first commit. Years of telemetry become your capital expenditure evidence.
Red flags
- A quote that does not count controller families. Site count barely moves this number. Distinct hardware and firmware vintages move it a great deal.
- Battery replacement driven by install date. A blanket five year swap wastes money on healthy strings and still misses the degraded one that drops a site.
- Polling with no edge buffer. You will have beautiful data on ordinary days and a gap on every outage that mattered.
- Dispatch ranked by distance. Nearest technician is not the same as the site that fails first, and predicted time to site down is the only ordering worth having.
- Hedging on ownership of device credentials. If access to your own estate sits in a supplier's tenancy, walk.
Questions to ask on the first call
- What happens to telemetry when a site loses backhaul during a mains failure?
- Describe the battery state of health method you would use before seeing any of our data.
- Which controller protocols have you driven on a live site, and on what transport?
- How would you get a capacity trend without sending crews to run discharge tests?
- How do you reconcile a fuel delivery docket against tank telemetry and modelled burn?
- How does the system decide which of six sites on battery should be visited first?
- Which of our sites need hardware fitted before they can report anything?
- What does adding a fourth rectifier family cost, and how long does it take?
- Who owns the code, the cloud accounts and the device credentials if we change firms?
A simple way to decide
Before you buy anything, look for one symptom. Ask whether your network operations centre currently filters power alarms out of the main view. If they do, you have already crossed the threshold where this pays back, because an ignored alarm queue is a more expensive condition than no alarms at all.
Then buy a paid discovery phase rather than a build. Four to six weeks, commonly $9,000 to $22,000, and the deliverable is a written specification you own: every controller family with a count of sites and an integration estimate, the transport at each, which sites need hardware fitted, the criticality model, the fuel reconciliation logic and a phased plan. Take that identical document to three firms and the prices become comparable for the first time.
Digital Heroes is the wrong choice under roughly 150 sites on a substantially single vendor rectifier estate. Vertiv, Schneider or Eaton monitoring against their own hardware will serve you, the integration is already done, and a build would be an expensive route to a similar screen. We are also wrong if your sites are grid stable, battery only and your fuel spend is negligible, because two of the three problems here do not apply. We fit tower companies, neutral host operators and mobile operators with genuinely multi vendor fleets, meaningful fuel and battery spend, and tenants whose contracts carry service credits. We work product requirement document first, you own the code from the first commit, and we contract through an India LLP, a US LLC or a UK LTD so intellectual property assigns under your own law.

The evidence behind this guide
Independent findings on why this investment pays off. Every link goes to the primary source.
- PTC identifies the leading causes of failed first visits as parts unavailability (the single most-cited complaint, named by 51% of field service executives), technicians lacking the required equipment or skills, and insufficient time allocated to the job - making parts logistics and skills-based dispatch the highest-leverage fixes. Source: PTC (2023) →
- ServiceTitan's KPI guide cites an average first-time fix rate near 80% (90% ideal) and describes strong technician-utilization rates as falling in the 60-80% band, with average travel time typically 30-60 minutes depending on service-area size. Source: ServiceTitan (2026) →
- The average developer spends more than 17 hours a week dealing with maintenance issues such as debugging and refactoring, and about four of those hours on 'bad code' - waste that equates to nearly $85 billion annually worldwide in opportunity cost. Source: Stripe (2018) →
- The right combination of digital transformation actions can unlock as much as US$1.25 trillion in additional market capitalization across Fortune 500 companies, while the wrong combinations put more than US$1.5 trillion at risk; companies with all three core factors (strategy, aligned technology, and change capability) saw a 5% market-value lift relative to peers.

Frequently asked questions
What is the difference between site power monitoring and a network management system?
A network management system watches transmission and service state. Site power monitoring watches the infrastructure keeping that equipment alive: rectifiers, battery strings, generators, fuel and environmental conditions. They raise different alarms and are usually owned by different teams. Many operators discover the gap during a storm, when the network view shows sites down and nobody can say which of them still has autonomy left.
How long does it take to integrate one rectifier or generator controller family?
Typically one to three weeks per family, including bench work against a lab unit and one validation at a live site. Skipping the lab unit is a false economy, because vendor documentation and the register map actually implemented in a given firmware release do not always agree. For discontinued hardware, obtaining a unit to test against can take longer than writing the driver itself.
Can battery health be assessed without running deliberate discharge tests?
Yes, for most of the fleet. Every unplanned mains failure is a free capacity test if the system captures the discharge curve, the load in amps, ambient temperature and time to recovery. Trended per string with temperature compensation, that produces a ranked replacement list from ordinary grid events. The exception is sites in stable grid areas that never discharge, and those are the small group genuinely worth a scheduled test.
What happens to telemetry when a site loses backhaul during an outage?
Without buffering at the edge, it is lost, and it is lost during precisely the events you built the system to understand. Collection has to store readings locally and replay them when the link returns, with enough local storage to survive a long outage. Ask any candidate about this in the first meeting, because a firm that has worked on outdoor sites raises it unprompted.
Who owns the device credentials and the telemetry history?
You should own all of it, stated in the contract before kickoff: repository, cloud accounts, device credentials and the accumulated history. That history becomes the evidence behind battery and generator capital requests for years, and access to your own estate should never sit inside a supplier's tenancy. Any hesitation on this point is reason enough to stop the conversation.
Do we need to fit new hardware before this works?
Sometimes. Sites with a rectifier controller already reporting over a network connection usually need nothing. Sites with no tank sender cannot report fuel level, and sites with no shunt cannot report load accurately. Decide which locations justify the fitting cost before the software scope is agreed, since it is a field programme with truck rolls and usually a different approver than the software budget.
Should we hire a firm whose experience is data centre power rather than telecom sites?
Be careful. Data centre power work is real engineering, but it happens in one building with reliable connectivity, coherent single vendor hardware and staff on site. Outdoor fleets bring marginal cellular links, mixed vintages of equipment, no permanent presence and events that arrive during the outage. Ask specifically what they have driven over a serial to cellular converter at a site with poor signal.
Can this drive field dispatch, or does it only raise alarms?
It should drive dispatch, and that is where most of the value sits. Ranking sites by predicted time to down against travel time from where technicians actually are beats sending the nearest person to the nearest problem. That requires integration with whatever field service scheduling you run, so name that system during scoping rather than treating dispatch as a later phase.
How much does it cost to add a fourth controller family later?
Agree a rate card up front, because you will add families through acquisitions and refresh programmes. A new family with a modern network interface is usually one to two weeks. One reachable only over serial with an undocumented register map can be three or more, plus the effort of sourcing a unit to test against. Pricing it while you still have alternatives is much cheaper than pricing it afterwards.
Should an operator with 120 sites on one rectifier brand build this?
Usually not. Your hardware vendor's own monitoring already understands that estate, the integration exists, and a custom build would be an expensive path to a similar screen. The case changes when the fleet becomes multi vendor through acquisition, when generators and fuel enter the picture, or when you sell uptime to tenants under contracts carrying service credits and need defensible evidence of what happened.
How long does it take to build a custom field service app with scheduling, dispatch, and a technician mobile app?
Plan on 12 to 16 weeks for a working first release covering scheduling, dispatch, and a technician mobile app, and 5 to 7 months for a full platform with offline mode and accounting sync. Across 2,000+ Digital Heroes projects, field service timelines slip in two predictable places: underscoped offline behavior and integration testing against QuickBooks or the payment processor. Both belong in week one of planning, not month four.
How long does it take to build a custom web or mobile app from scratch?
Plan on 8 to 16 weeks for a focused first version and 4 to 9 months for a larger platform, which is the typical spread across Digital Heroes builds. The first 2 to 3 weeks go to discovery and design before any production code ships. The two things that stretch timelines most are integrations with legacy systems and slow feedback from your side, not developer speed.
We're outgrowing Jobber. Should we move up to ServiceTitan or build our own?
Move to ServiceTitan if the problem is missing features on a standard residential trades workflow, because migrating between products is far cheaper than building. Build custom when the problem is fit: multi-day commercial jobs, subcontractor crews, or pricing rules that neither Jobber's Grow plan (about $199 per month billed annually, up to 15 users) nor ServiceTitan models cleanly. In Digital Heroes scoping calls, about half the teams asking this question turn out to need an integration or add-on rather than a new platform, so name the exact workflow gap before committing either way.
We run everything on spreadsheets and Airtable. How do we know it's time for custom software?
The reliable signals are re-typing the same data into multiple tools, one employee acting as human middleware between systems, and errors appearing in handoffs between teams. Hard limits force the issue too: Airtable's Team plan caps at 50,000 records per base, and Business costs $45 per seat per month, so a 20-person team pays about $10,800 a year for a tool it has already outgrown. When workarounds consume more hours than the tools save, the spreadsheet era is over.
How much should a small business budget for its first custom app or website?
For a focused first build, most small businesses land between $8,000 and $60,000: roughly $8,000 to $45,000 for a custom website and $25,000 to $60,000 for an internal tool or simple web app, based on Digital Heroes delivery across 2,000+ projects. Customer-facing products with payments, logins, or a mobile app start around $40,000. Quotes far below these bands usually mean a template with your logo on it, not software shaped around your workflow.
What should I have ready before I contact a development agency about field service software?
Bring your current workflow, not a feature list: how a job moves from first call to paid invoice today, where it breaks, what tool you use now with its monthly bill, and the workaround spreadsheets your team maintains. Add your integration list (accounting system, payment processor, phone system) and an honest budget range. A good agency can scope accurately from that in one or two calls, while a vague request for an app like ServiceTitan costs you weeks of discovery.
What tech stack should a custom field service platform be built on?
The dependable 2026 stack is React Native or Flutter for the technician app, React for the dispatch console, Node.js or Python on the backend, and PostgreSQL with an offline sync layer on the device. Boring, widely used technology wins here because any competent team can maintain it five years from now. Be wary of an agency proposing a stack only they can staff; that is a lock-in strategy, not an engineering decision.
Who can build a custom field service management software system?
Digital Heroes builds custom field service management software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other field service management software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it.
