Custom Software Development Company
Codroon is a custom software development company that builds software around how your business actually works: internal tools, bespoke applications, and replacements for systems that stopped fitting years ago. Fixed price, weekly demos, and a codebase your team can maintain without us.
What is custom software development?
Custom software development is building an application specifically for one organisation's process, rather than adapting that process to fit a product built for everyone. It's the right call when the way you work is a genuine advantage, or when what's available off the shelf gets you sixty percent of the way and the remaining forty is where the value lives.
It's the wrong call more often than most agencies will admit. If a $50-a-month tool does ninety percent of it, buy the tool. Codroon builds custom software when the alternative is worse: when the spreadsheet has become critical infrastructure, when the system that runs your operation is a decade past fitting, or when the workaround costs a person a week every month. We'll tell you which side of that line you're on before you spend anything.
Fixed price vs time and materials vs hiring developers
Three ways to buy custom software. The difference isn't cost. It's who carries the risk when the project takes longer than anyone expected.
| Comparison point | Fixed price | Time & materials | Staff augmentation |
|---|---|---|---|
| How you pay | One agreed number | Hourly or daily, as it goes | Monthly per developer |
| Who carries overrun risk | The vendor | You | You |
| You're actually buying | An outcome | Effort | Capacity |
| Best when | Scope can be defined up front | Scope genuinely can't be | You have the management to direct them |
| Falls apart when | Requirements shift constantly | Nobody's watching the burn | You have no technical lead |
| Change costs | A change order, discussed | Invisible until the invoice | Absorbed, and the deadline moves |
| Typical of | Studios that scope properly | Most agencies | Offshore dev shops |
Codroon works fixed price. It requires more discovery work up front and it means we carry the risk of our own estimates, which is the point. If your scope genuinely can't be defined yet, the honest first step is a paid discovery, not a build.
Our custom software development services
Codroon builds four kinds of custom software. Most engagements start with the first or the last.
Internal Tools & Operations Software
The systems your team uses to actually run the business: dashboards, approvals, scheduling, inventory, reporting. Usually replacing a spreadsheet that three people depend on and one person understands.
Bespoke Business Applications
Customer-facing software that isn't a SaaS product: portals, booking systems, quoting tools, marketplaces. Built around your process rather than bent into someone else's template.
Legacy Modernisation
Replacing or extending a system that still works but has become the thing holding you back. Done in stages, with the old system running until the new one has earned the switch.
Technical Discovery & Scoping
For when you know something's broken but not what to build. A structured engagement producing a specification, an architecture, and a real cost, which you can then build with us or take to anyone.
Looking for something more specific?
Custom software is the broad answer. If your project has a shape, these are more specific:
- AI Agent Developmentsoftware that decides and acts on its own
- Generative AI DevelopmentAI features inside an existing product
- AI Integrationconnecting AI to systems you already run
- MVP Developmentproving an idea before committing to it
- SaaS Developmentmulti-tenant products with billing
Not sure which? That's a normal place to start. The discovery call sorts it.
How Codroon builds custom software
Four steps, six to twelve weeks, and it starts with the problem rather than the solution you came in describing.
Problem definition
Free, 45 minutesMost people arrive describing software. We go back one step and ask what's actually breaking, because the answer is frequently a different build, or a much smaller one. You leave with a written problem statement, a recommended approach, and a real number, yours to keep either way.
- problem statement
- recommended approach
- fixed price and timeline
Discovery and specification
Weeks 1–2We sit with the people who'll use it and map how the work happens now, including the workarounds nobody documented. That's where the requirements actually live. You get a specification you could hand to any developer, not just us.
- process map
- written specification
- screens and data model
Build in weekly demos
Weeks 3–8Working software every week, in front of the people who'll use it. Internal tools fail on adoption more often than on engineering, so the users see it early and often rather than at a launch meeting.
- weekly working builds
- integrations
- test coverage
Deploy, train, hand over
Weeks 8–12We deploy, run training with the actual users, and hand over the repository with documentation written for whoever maintains it next. Software nobody was taught to use is shelfware, however well it was built.
- production deployment
- user training
- repo, docs, runbook
The stack Codroon builds on
Chosen for how easy they'll be to hire for in three years, not for how interesting they are today.
- Application
- Next.js, React, and TypeScript. Standard, well-documented, and familiar to any developer you bring in later. That matters more for custom software than for anything else we build, because you'll own it for years.
- Backend and data
- Node and Python, PostgreSQL as the default. We also work against databases you already have rather than insisting on a migration you didn't ask for.
- Integration
- REST, GraphQL, webhooks, and queues for connecting to the systems already running your business: accounting, CRM, ERP, warehouse. Most custom software is only useful if it talks to what's already there.
- Auth and access
- SSO through your existing identity provider, with role and permission models built to match how your organisation actually delegates authority.
- Reliability
- Sentry for errors, structured logging, automated backups, and monitoring. Internal tools become critical faster than anyone plans for, so they get treated as critical from the start.
- Infrastructure
- AWS and Docker, deployed to your accounts under your name. Infrastructure as code, so it's reproducible rather than clicked together once and forgotten.
When custom software is the right answer
Four situations where building beats buying. If yours isn't one of these, Codroon will probably tell you to buy something instead.
What custom software development costs
Most custom software projects with Codroon run $15,000–$50,000 and take six to twelve weeks. A focused internal tool replacing one process sits at the lower end. Multiple user roles, integrations with existing systems, and a staged legacy replacement sit at the upper.
We work fixed price, quoted after discovery. Not hourly, and not a rate card that grows with the project. If discovery shows an off-the-shelf product does the job, we'll say so and you'll have spent nothing.

Custom software development: common questions
Most custom software projects take six to twelve weeks and cost $15,000–$50,000, quoted as a fixed price. You own the code and the documentation, and it's built on a standard stack any developer can maintain. The problem definition call is free.
Let's work out what's actually broken
Forty-five minutes, no prep, no commitment. Tell us what isn't working and you'll leave with a problem statement, a recommended approach, and a real number, even if the answer turns out to be buying something instead.
