Custom software development services

  • Discovery and solution design

    Workshops, a technical audit and architecture, so you know what we’ll build, in which stack and why, before development starts.

    Customer portals, dealer and partner platforms, and booking and ordering systems built around how your business actually works.

  • Custom CMS and content platforms

    Headless and custom content platforms for teams a standard CMS can’t serve, like the shared headless CMS built in Laravel behind Zodiac and Astral Pool.

  • Laravel, Node.js and .NET development

    Laravel for content-rich platforms, Node.js for real-time and JavaScript-first apps, and .NET for enterprise and Microsoft environments.

  • Mobile and kiosk apps

    iOS, Android and tablet apps connected to your platform, like Rhino-Rack’s in-store Product Finder kiosk.

Why product and IT teams choose our software developers

Most of our developers have been with Tonic for five years or more, so the people who build your platform are still here to support it.

  • Stack-agnostic

    Laravel, Node.js and .NET in one team, so we recommend the stack that suits your platform, not the one we’d rather sell.

  • From credit checks to ticketing

    We’ve built automated credit checks and approvals for FleetPartners and an Enta ticketing integration for Sydney Festival.

  • Upgrades, not rewrites

    We upgrade and extend platforms another team built, starting with a code review of what to keep.

  • Hosting you can rely on

    CI/CD pipelines, monitoring and security patching on infrastructure like AWS.

How a custom software project runs

  1. Discovery (weeks 1–2)

    Workshops with the people who’ll use the software, a technical audit of your systems and a clear problem statement.

  2. Solution design and scope (weeks 3–4)

    Architecture, stack recommendation, API contracts, hosting plan and a fixed scope for the first release.

  3. Build in sprints

    Fortnightly sprints with demos on a staging environment that matches production, and real-time scope reporting.

  4. Test and launch

    Automated tests, QA, security testing and a planned cutover, with data migrated from the old system.

  5. Support and improve

    SLA support, monitoring and a roadmap of improvements from the team that built it.

Custom software development FAQs

What is custom software development?

Custom software is built for your business rather than bought off the shelf: portals, platforms, internal tools and APIs shaped around your workflows and systems. We build it in Laravel, Node.js or .NET, depending on what suits your team and infrastructure.

Should we use Laravel, Node.js or .NET?

Laravel suits content-rich platforms and admin-heavy applications, Node.js suits real-time features and JavaScript-first teams, and .NET suits enterprise and Microsoft environments. We recommend the stack that fits your team, hosting and existing systems.

Can you take over an existing codebase?

Yes. We start with a code review covering architecture, dependencies, security and tests, then tell you what we’d keep, fix and replace before taking it on.

Can you upgrade an older Laravel, Node.js or .NET application?

Yes. We plan upgrades in stages, update dependencies, add automated tests and release on a staging environment that matches production before going live.

Do you build APIs and integrations?

Yes. We build REST and GraphQL APIs and connect platforms to CRM, ERP, payments and ticketing systems, such as Sydney Festival’s integration with Enta and FleetPartners’ automated credit checks.

Do you build React and Next.js front ends?

Yes. We build fast, accessible front ends in React and Next.js, like the Sydney Festival Digital Archive, server-rendered in Next.js on Node.js.

Where do you host custom software?

On the infrastructure that suits your platform and team, including AWS, with CI/CD pipelines, monitoring and staging that matches production.

Who owns the code?

You do. You get the repositories, documentation and handover notes, so there’s no lock-in. If you ever move the platform to another team or bring it in-house, everything they need is already in your hands.

How long does a custom software project take?

It depends on scope. Discovery and solution design take about four weeks, and a first release usually follows within a few months, delivered in fortnightly sprints.

What does custom software development cost?

Cost depends on the scope, the number of integrations, the stack and how much data needs to be migrated. Starting with a focused first release keeps the initial investment lower. After discovery, you get a fixed scope and price for the first release, with real-time scope reporting during the build.

Do you support Laravel, Node.js and .NET applications after launch?

Yes. The developers who build your platform support it under SLAs, covering monitoring, security patching, framework upgrades and ongoing improvements. That keeps Laravel, Node.js and .NET versions current and avoids costly rebuilds later.

Is your development team in-house?

Yes. Our developers work in-house from our Surry Hills studio in Sydney, so you deal directly with the people designing, building and supporting your software.
