The short answer

What custom software development means

Software shaped around your workflows, users and growth plans.

What is custom software development?
Custom software development is the design, engineering and release of software built for one business, its workflows and its users, in place of a licensed off-the-shelf product. It covers web, mobile, desktop and progressive web apps, internal tools and integrations, so the result fits the operating model, data and growth plans of the company that owns it.

Related: web application development, SaaS development and mobile app development.

Web applications

We build browser-based apps and portals for Windows and Mac users in React, Angular, Vue and Node.js.

See web application development

iOS apps

We build native apps for iPhone and iPad in Swift, SwiftUI and UIKit.

Android apps

We build native Android apps on Kotlin, Java and Jetpack.

Cross-platform apps

One shared codebase in React Native or Flutter runs on both iOS and Android.

See mobile app development

Desktop applications

We build native Windows and macOS apps with offline support in .NET, C# or Java, and .NET developers can join your team to maintain them.

Progressive web apps

Progressive web apps install from the browser and skip the app store, with offline support and push notifications.

MVPs

A first version that tests the idea with early users before the full build.

See MVP development

Wearable apps

We build smartwatch, fitness and medical device apps on WatchKit and Wear OS.

Not sure which platform you need?

Cross-platform costs less for the same scope, and native gives more performance. We will tell you which one fits your users and budget.

Field service apps integrated with NetSuite: web, Android and iPhone

ScalaCode built web, Android and iPhone apps for a field service company to replace its Service Pro software. Field workers view jobs, complete inspections, add photos and notes, and everything syncs with NetSuite through a secured backend.

When custom software beats off-the-shelf tools

Off-the-shelf software is the faster choice when your process matches how the product works. Custom software pays back when the process is what sets you apart, or when licence costs grow with every seat.

Questions buyers ask

Custom software development FAQs

Custom software starts from $9,999 after a free discovery sprint. Ask anything not covered here on the call.

How much does custom software development cost?

Custom software starts from $9,999 for a scoped build, with working software demoed every two weeks. Every fixed quote follows a free discovery sprint. Complex features, custom UX design and third-party integrations are the main cost drivers.

How long does a custom software project take?

An MVP takes 6 to 8 weeks. For larger applications, the discovery sprint fixes the timeline in writing before the build starts, and our engineers build with AI coding agents, which shortens delivery.

Fixed price or time and materials: which should we choose?

Choose fixed price when the scope is defined and unlikely to move, such as an MVP or a portal rebuild. Choose time and materials, with a monthly cap, while requirements are still changing. Many clients start fixed price for version one and move to a dedicated team for the roadmap after launch.

Who owns the source code?

You do, from the first commit. IP assignment is written into the master service agreement, and NDAs are standard. Code, infrastructure configuration and documentation are handed over in full.

Can you take over an existing codebase?

Yes, after a technical audit. We document the state of the code and the risks, then run a three to four week stabilisation sprint before new features.

How do you keep us updated during the project?

You see working software at the end of every two-week sprint, demoed to your team. Written status goes out every week, and code reviews stay open to your engineers in your own repository.

Should I build native apps or use cross-platform?

Cross-platform costs less for the same scope, and native apps give higher performance and responsiveness. The right choice depends on your audience, the features you need and your budget.

Can you launch an MVP quickly to test our idea?

Yes. An MVP starts from $9,999 and takes 6 to 8 weeks. We build a smaller working app around the main idea, test it with early users, then build the full product. Property portals for real estate teams are a common first build of this kind.

What technology stack will you use?

Swift and Kotlin for native apps, React Native and Flutter for cross-platform, React, Node.js, Python, Java and .NET for web and backend, and PostgreSQL, MongoDB, Firebase and AWS for data and infrastructure. We pick per project, based on your scope and your team's skills.
