    Frequently Asked Questions

    Here's a list of FAQs that will help you learn more about DianApps.

    Why should Sydney-based businesses choose a local custom software development partner?

    Sydney businesses operate in fast-moving, regulation-heavy environments where speed, clarity, and accountability matter. Working with a custom software development company serving Sydney ensures real-time collaboration, alignment with Australian business regulations, and software built for local customer expectations. DianApps supports Sydney companies with enterprise-grade solutions while eliminating time-zone and communication gaps.

    What does custom software development cost for Melbourne businesses?

    For Melbourne-based companies, custom software development typically ranges from $50,000 to $500,000+, depending on complexity, integrations, and long-term scalability requirements. After understanding your business goals and technical needs, we provide transparent, milestone-based pricing to keep budgets predictable and controlled.

    Can you work with our existing development team?

    Absolutely. Our custom software developers frequently augment in-house developers by adding specialized skills, increasing delivery capacity, or supporting large-scale initiatives. We integrate seamlessly with your internal developers while maintaining clear ownership and accountability.

    How do you ensure our software is secure?

    Security is embedded from day one. We follow industry best practices such as encrypted data transmission, secure authentication, role-based access controls, and regular security audits. Our processes align with standards like ISO 27001 and the Australian Privacy Principles.

    What industries do your custom software developers specialize in?

    We’ve delivered successful custom software solutions across healthcare, financial services, retail, education, logistics, manufacturing, and more. Our team combines technical expertise with deep domain understanding relevant to Australian businesses.

    How is custom software development better than buying off-the-shelf software?

    Off-the-shelf software forces you to adapt your business processes to fit the tool. Custom software development creates solutions tailored to your exact workflows, allowing you to build unique features, scale without constraints, and gain a competitive advantage that generic platforms simply can’t offer.

    How long does it take to build custom software for Brisbane-based companies?

    Most Brisbane businesses can expect custom software development timelines of 3–6 months. Simpler applications may be delivered in 6–8 weeks, while complex enterprise platforms can take 9–12 months. We define accurate timelines after a structured discovery phase and clear scope alignment.

    What happens after you launch our custom business software?

    Post-launch, we provide ongoing support including bug fixes, performance optimization, security updates, and feature enhancements. Many clients continue working with us on a monthly retainer to ensure their software evolves alongside their business and market demands.

    Do you sign non-disclosure agreements (NDAs)?

    Yes. We sign NDAs before any detailed project discussions begin. Your intellectual property, business logic, and confidential information remain protected throughout our engagement and beyond.

    How do we get started with DianApps?

    Getting started is simple. Book a free consultation where we discuss your goals, challenges, and requirements. We’ll provide honest input on feasibility, suggest the right approach, and, if we’re aligned, share a detailed proposal with timeline and investment clarity.
