UX and UI design

Project cost depends on the complexity of the software being built. A small to mid-complexity website built to enterprise standards typically ranges from $25K–$60K + GST. These projects usually take two to four months with a team of three, and include UX, creative design, frontend and backend development, QA, enterprise CMS, DevOps, cloud infrastructure, web forms, and a simple integration.

More complex enterprise platforms typically range from $100K–$250K+ GST and take four to nine months to deliver. This includes SaaS products, enterprise systems, marketplaces, searchable directories, and operational platforms. These projects often involve extensive custom software, dashboards, multi-user permissions, advanced integrations, automation and AI features, payment systems, scalability, security, and robust cloud infrastructure.

Vendor-grade software designed for large-scale user bases requires an even higher level of investment. These projects demand rigorous compliance, tight release cycles, dedicated QA and testing, full-time project management and business analysis, detailed documentation, and advanced UX/UI systems such as component-driven design frameworks. The additional complexity and operational overhead significantly increase the overall cost.

Hidden costs in custom software projects are usually predictable — if the project is properly planned from the start.

Be cautious of vague estimates or unusually low quotes. In many cases, hidden complexity sits within integrations, legacy systems, and unclear technical requirements. That’s why we invest time early in discovery and technical planning, identifying risks before development begins. Poorly defined requirements also increase the likelihood of scope changes and project variations later in the build. Clear planning upfront reduces surprises, keeps budgets under control, and improves delivery certainty.

Clients should also consider ongoing operational costs such as cloud hosting, infrastructure maintenance, software patching, end-of-life upgrades, and third-party licensing. For example, high-volume SMS notifications, payment gateways, AI services, or CDN infrastructure can introduce additional usage-based costs.

Beyond the platform itself, there may also be future marketing, SEO, and growth costs to factor into long-term digital success.

Too often we are asked to rescue someone else's software project, and we hear the same story: “We were told the project would take a few months. Now it’s dragged on far beyond the original timeline, with no clear end in sight.”

At Hemmingway, we focus on identifying hidden complexity early and delivering with clarity, speed, and accountability. We like to surface work as soon as possible for review and feedback on a demo or staging server. Our approach is built around clarity in technical planning, realistic timelines, MVP-first thinking, frequent demos, and milestone-based delivery — so you always know where the project stands. If speed to market matters, we’d love to talk.

Building the right software starts with a clear, shared understanding of the problem you’re solving. Before development begins, we work closely with you to map workflows, define requirements, and uncover hidden complexity early. Through workshops, wireframes, prototypes, and regular feedback sessions, we align stakeholders before major development starts.

You’ll see your system come to life in real UI screens early in the process, giving you confidence in exactly what’s being built before development and QA accelerate. Our iterative delivery approach also means you’ll see progress regularly — not months later at final release. Frequent demos and feedback loops allow us to test ideas early, refine the solution as we go, reduce project risk, and deliver software that creates genuine value for your business and users.

With 23 years of experience in custom web software, every project is overseen by our senior development team based in Sydney and Brisbane. We don’t outsource projects offshore or hand work between unknown contractors — everything is delivered in-house by our own team.

Our teams are made up of specialists with deep expertise in their field, rather than generalists wearing multiple hats. That means your backend developer isn’t designing interfaces, and your UX specialist isn’t writing database code. Each role is handled by experienced professionals focused on what they do best. A typical project team includes:

• Product Managers to shape scope and roadmaps;

• UX/UI Specialists to design intuitive user experiences;

• Project Managers to coordinate delivery and communication;

• Software Architects to lead technical direction;

• Specialist frontend and backend developers to build the platform;

• QA specialists who rigorously test the solution before launch.

Priorities often change during software projects as businesses evolve, new ideas emerge, or market conditions shift. That’s why we use a flexible, staged delivery approach that allows priorities to be reviewed and refined throughout the project, rather than locking everything in on day one. When priorities change, we work closely with you to assess the impact on scope, timelines, and budget before major adjustments are made. Through clear communication, phased delivery, and ongoing prioritisation, we keep projects moving forward while adapting to changing business needs.

Where possible, we’ll accommodate smaller changes within the existing fixed scope at no additional cost — that is always our goal. If a change requires significant rework or additional development effort, we’ll provide a transparent project variation and re-quote the work as fairly and cost-effectively as possible.

Software requires ongoing maintenance to remain secure, stable, and performant. Applications need updating, integrations evolve, databases require backups, and operating system or browser changes can create compatibility issues over time. Businesses also need new features and enhancements as operations grow and change — all of which can place significant pressure on internal IT teams.

By outsourcing support to us, you gain access to an experienced software team that becomes an extension of your business. We proactively monitor, maintain, optimise, and improve your systems, helping reduce downtime, improve efficiency, and protect business continuity across legacy platforms, off-the-shelf software, and custom applications.

Our flexible, no lock-in approach gives you the freedom to scale support as needed, without rigid contracts or unnecessary overhead. Whether you need a monthly maintenance plan, discounted blocks of support hours, or a fully tailored support arrangement, we can adapt to suit your operational needs.
