Custom Field Service App Development · Flutter & React Native

We Build Field Service Software Around How Your Team Works

Not a product you adapt to. We start every field service app development project by talking to your dispatcher, your crews, and your ops team, then build the exact field service management software your operation needs, whether you run construction crews, trade contractors, or maintenance teams. Every project is different. That is the point.

30 minutes. No commitment. We will ask about your operation, tell you what we would build, and give you a straight answer on cost and timeline.

Why Companies Come to Us

Why Field Service Companies Build Custom Software

The same four situations come up on almost every first call. If any of these sound familiar, a custom app is probably the right conversation to have.

Situation 1

Your dispatcher is spending half the day on the phone

Assigning jobs, answering questions about addresses, relaying information that should already be in the technician's pocket. That is not a people problem. It is a software problem, and it is solvable.

Situation 2

You have no real time view of where your team is

When a priority job comes in, you are calling technicians one by one to figure out who is closest. That gap between what is happening in the field and what you can see from the office costs you time and jobs.

Situation 3

Job reports come back late, incomplete, or not at all

Paper forms, photos on personal phones, signatures that never make it back to the office. The job is done but the documentation is not, and that creates billing delays, disputes, and compliance risk.

Situation 4

Off the shelf software doesn't fit how you actually operate

You bought ServiceTitan or Jobber and your team works around it instead of with it. The platform was built for the average field service company. Your business is not average, and the workarounds are costing you more than the subscription.

What Changes

What Changes After a Custom Field Service App

Not a feature list. A description of what your dispatcher's day looks like, and your technicians' day, and yours.

Before
Dispatchers call technicians to assign jobs, give directions, and answer questions
No real time view of where the team is or what they are working on
Paper forms and photos on personal phones that never make it back to the office
Per seat pricing that increases every time you hire someone new
Workarounds for the features your platform was never designed to support
After
Work reaches the field without a single phone call, with everything the crew needs to start
The office sees what is happening in the field all day, without asking anyone
Documentation is complete before the crew leaves the site, not days later
One cost to build, then yours. No per seat fees, no price increases, no vendor dependency.
Software that matches how your team actually works, built around your specific workflows
How We Start Every Project

How We Scope a Custom Field Service App Development Project

Most software projects fail because the team starts writing code before they understand the operation. We start differently.

01

We talk to the people who will actually use it

Not just the decision maker. We want to hear from your dispatcher about how they assign jobs today. From a technician about what information they need at the start of a job. From whoever chases reports at the end of the day. That is where the real requirements come from.

02

We map your current workflow before proposing anything

How does a job get created? How does a technician find out about it? What happens when there is a problem on site? What does a completed job look like in your system? We need to understand all of that before we suggest what to change or automate.

03

We tell you what we would build and why

After the discovery call, we put together a scope document that describes the app in plain language, not technical specs. You read it and tell us where we got it wrong. That document becomes the basis of the fixed price quote.

04

You get a fixed price before anything starts

We give you a complete cost and timeline before you commit. Milestone payments tied to working software, not invoices tied to hours. If the scope changes, we talk about it before it affects the price.

Questions we ask on the first call

On dispatchHow does your dispatcher find out a new job needs to be assigned? How do they decide which technician gets it?

On techniciansWhat does a technician do when they arrive at a job? What information do they need that they don't currently have in one place?

On reportingWhat needs to be documented after a job is complete? Who needs to see it and when?

On the current setupWhat tool do you use today and what is the one thing it cannot do that costs you the most time?

On successWhat would need to be true six months after the app launches for you to consider this a success?

Every Project Is Different

Every Field Service App Development Project Is Different

This is what custom development means in practice. The same category of business, field service, but three different operations that needed three different solutions.

General contractor · 60 field technicians

The problem was dispatch speed

They ran repair and installation crews across active construction sites and needed to assign urgent jobs within minutes, not the 20 minutes it took to find the right crew by phone. We built the coordination side of their operation first, and assignment went from a phone chain to seconds. Everything else came in later phases, after they had seen how the core worked.

Fire protection contractor · 30 inspection routes

The problem was recurring inspection management

Every building had a scheduled inspection frequency and a service history that technicians needed to reference on site. The problem was not dispatch. It was that technicians had no access to that history in the field. We built around that first.

Facilities management · 12 buildings

The problem was documentation and sign off

They were losing contracts because completed work couldn't be proved fast enough. The app we built focused on one thing: making finished work provable the same day it was done, straight from the site to the property manager. Everything else was secondary.

Not sure what your app should look like?

That is exactly what the discovery call is for. You describe your operation, we ask questions, and by the end of 30 minutes you will have a clearer picture of what the right software looks like for your business.

TimeFix

The client managed technicians across multiple job sites and ran the whole operation through phone calls and a shared Excel spreadsheet. They did not come to us with a feature list. They came with a problem: coordination ate too much office time and job documentation came back too slowly for billing. We mapped their workflow, identified the two things that would have the most impact, and built around those first. The first version went live in 10 weeks.

The Business Case

The Real Cost of Running Field Service Without Custom Software

The cost of custom field service app development is visible on a single invoice. The cost of not having the right software is invisible, spread across daily inefficiencies that never show up in one place.

Hidden costs of the status quo
Dispatcher time on job status calls and re-routing
2+ hrs/day
Delayed reports, missing paperwork, end of day chasing
45 min/day
Technician downtime from unclear job info
1 hr/tech/day
Per seat software licenses at 60 technicians
~$7,200/mo
What changes after a custom app
Coordination handled by the system, not by phone calls
Dispatcher freed
Documentation complete before the crew leaves the site
Billing unblocked
Crews arrive knowing exactly what the job is
Less downtime
One time build cost, flat fee, no per seat pricing ever
You own it

A custom field service app for a 60-technician team typically pays for itself within the first year through dispatcher time savings and eliminated seat fees alone. Book a call and we will work through the numbers for your specific operation.

Field Service App Development Process

How a Field Service App Development Project Works

Week 1

Discovery call and workflow mapping

We talk to your team, map how dispatch and reporting work today, and identify the highest impact things to build first. You get a scope document in plain language that describes the app before we write a line of code.

Week 1

Fixed price and milestone plan

We turn the scope document into a fixed price with milestone payments. You know the full cost before anything starts. If the scope changes during the project, we agree on it before it affects the price.

Weeks 2+

Build by milestone, demo every two weeks

We build in stages and demo working software at every milestone. You review, give feedback, and we move on. No surprises at the end. The app you see at launch is the one you have been reviewing throughout.

Launch

Submission, training, and full handover

We handle App Store and Google Play submission, run a training session with your dispatch team, and hand over the complete source code and documentation. Post launch support is included. You own everything.

How We Work Together

Two Ways to Build Your Field Service App

Fixed price project

We scope the work, agree a fixed price with milestone payments, and deliver a complete, production ready app. Best for operations teams with a clear problem who want a defined outcome on a defined timeline. No hourly billing, no open ended engagement.

Dedicated developer

A senior Flutter or React Native developer embedded in your team, full time or part time. Best if you already have an app or internal engineering team and need an experienced developer to extend, maintain, or improve it on an ongoing basis.

Common Questions

Field Service App Development: Common Questions

How much does custom field service software cost to build?
A focused first version, built around the core of how your operation runs, typically costs between $30,000 and $60,000 depending on scope. Larger systems that connect more of the business run higher. We give you a fixed number after the discovery call, not a range. There are no surprises after you sign.
How long does it take?
A focused first version typically takes 8 to 12 weeks from scope agreement to launch. More complex systems take longer. We give you a specific timeline with the fixed price quote, and we break delivery into milestones so you see working software throughout, not just at the end.
Will the app work when technicians lose signal?
Yes. We build offline first by default for field service apps. Crews can keep working with zero signal and everything syncs automatically when the connection returns. This matters especially for teams on construction sites, in basements, warehouses, or anywhere coverage is unreliable.
We already use ServiceTitan. Does it make sense to switch to something custom?
It depends on your situation and we will tell you honestly. If ServiceTitan is working and the per seat cost is manageable, a custom app may not be worth it yet. Where custom wins is when the seat bill at 50+ technicians is significant, when your workflows don't fit the platform, or when there is something ServiceTitan cannot do that matters to how you operate. We will give you a straight answer on the first call.
Can you integrate with tools we already use?
Yes. We connect to the accounting, payment, messaging, and mapping services your business already runs on. What is possible depends on what each tool supports, and we confirm all of it before you commit to anything.
Do we own the source code?
Yes. You get the complete source code, design files, and documentation from day one. You can host it anywhere, hand it to another developer, or bring it in house. There is no vendor lock in and no ongoing fees unless you choose to keep us on.
Your team is in Poland. How does that work?
We work with operations teams across the US, UK, and Europe. We schedule standups and demos at times that work for your team, communicate on Slack, and deliver milestone demos on video calls. Every client we have worked with has said the distance is not something they notice in practice. What matters is how well we communicate and whether we deliver what we said we would. You can read more about how our Flutter development team in Poland works with US and UK clients.
