    Custom Software Development Company — Melbourne, Moorabbin & Australia-Wide

    NexIT builds tailored software solutions for Australian businesses across industries — from ERP and CRM systems to SaaS platforms and R&D-eligible applications. Whether you’re a startup ready to build your first product or an established business looking to replace legacy systems, we deliver clean, maintainable code and transparent project management from discovery to deployment. Our team works closely with your stakeholders throughout, so the software we build genuinely solves the problem it was designed for.

    Your Software Development May Qualify for the R&D Tax Incentive

    Many Australian businesses don’t realise that custom software development can qualify under the ATO’s Research & Development Tax Incentive program — worth up to a 43.5% refundable tax offset for eligible companies. If your project involves genuine technical innovation, experimentation, or solving a problem where the outcome is genuinely uncertain, it may qualify. NexIT structures and documents our development activities to support your R&D claim — from activity descriptions and technical logs to experimental evidence. We work alongside your R&D tax advisor to make the claim process straightforward.

    Software Development Questions — Answered

    Do you build custom software for businesses outside Melbourne?

    Yes — NexIT builds custom software for businesses across all of Australia. Our development team is based in Melbourne CBD (120 Spencer St) and Moorabbin (13 Cochranes Rd), but we deliver projects for clients in Sydney, Brisbane, Perth, Adelaide, and regional areas. All projects are managed remotely with structured communication and regular milestone reviews.

    Can my software development project qualify for the ATO R&D Tax Incentive?

    Many custom software projects qualify under the ATO's R&D Tax Incentive — worth up to a 43.5% refundable tax offset for eligible companies. If your project involves genuine technical experimentation or solving a problem where the outcome is uncertain, it may qualify. NexIT documents the development process — experiments, technical hypotheses, and outcomes — to support your R&D claim alongside your registered tax agent.

    How long does a custom software project typically take?

    Project timelines depend on complexity, scope, and how well requirements are defined. A focused MVP typically takes 8–16 weeks; a full ERP or SaaS platform can take 6–18 months. We work in iterative sprints so you see working software early and can adjust direction based on real feedback. We provide a project estimate and timeline after the discovery phase.

    How much does custom software development cost in Australia?

    Custom software costs vary widely based on complexity, integrations required, and team size. A focused internal business tool might cost $30,000–$80,000; a full SaaS platform with multi-tenancy and subscription billing typically ranges from $80,000 upward. Book a free consultation and we'll scope your project and provide a realistic estimate — no obligation.

    What is the difference between custom software and off-the-shelf solutions?

    Off-the-shelf software is built for generic use cases and often requires you to adapt your processes to fit the tool. Custom software is built around your exact workflows, data structures, and business rules — meaning it fits your business from day one and scales with you. For businesses with unique processes or complex integrations, custom software typically delivers a higher long-term ROI than adapting a generic product.
