What Does Custom Software Cost in Australia in 2026?

Search for what custom software costs and you'll find answers from $5,000 to $500,000. Neither end helps you plan. This post gives rough Australian prices, explains what moves them, and lists the running costs to budget for after launch.

Prices in this post are in Australian dollars. Hireadev isn't registered for GST, so no GST is added to our prices.

Rough prices by project type

Typical custom tools cost $25,000 to $150,000 and take 8 to 18 weeks. Mobile apps and larger systems are quoted after a paid discovery. Small automations that connect tools you already use cost much less. See business process automation.

If you get a quote far below these ranges, ask what's included. It may be a prototype rather than a finished product, or it may have been priced before anyone understood the full job. Either way, the gap can come back later as extra charges.

What pushes the price up or down

The biggest factors are:

• How many types of users there are, and how many screens each one needs.
• Connections to other systems, such as Xero, MYOB or Stripe. These are often where surprises turn up.
• How much old data needs moving, and how messy it is.
• How many reports you need, and how complex they are.
• How clear the requirements are at the start. Unclear scope costs more, because work gets redone.

It helps to know what you're paying for. A build covers planning, the features you asked for, connections to other systems, testing, and fixes after launch. A fair share also goes on things users never see, like logins, permissions, backups and hosting setup. Those are what keep the app working as it grows.

Running costs after launch

The build is not the only cost. Budget for:

• Hosting on a cloud service such as Azure or AWS.
• Paid services the app relies on, such as email sending, sign-in or error monitoring.
• Support and small changes, either on a monthly arrangement or as needed.
• Upgrades every few years, as the tools the app is built on release new versions.
• Apple and Google developer account fees, if there's a mobile app.

Ask for a written estimate of yearly running costs before you commit. A good developer will give you one.

Custom or off-the-shelf?

Custom software almost always costs more than an off-the-shelf product in the first year. It can pay off over time when:

• You pay for a lot of user licences. For example, $40 a user a month for 50 users is $24,000 a year, every year.
• Staff spend hours each week copying data between tools. Work out what that time costs you in wages over a year.
• No product fits the way you work, and bending your business to fit one is costing you customers or time.

If none of these apply, stay with off-the-shelf software. We'll tell you if that's the case.

Five ways to keep the cost down

1. Build in stages. Fix the worst problem first. The time it saves can help pay for the next stage.
2. Separate must-haves from nice-to-haves before the build starts. Scope creep is a common reason budgets blow out.
3. Use proven services for logins, payments and email, such as Stripe for payments, instead of building them from scratch.
4. Leave extras until someone actually needs them. Features can be added later.
5. Choose a developer you can talk to easily. A cheaper hourly rate doesn't help if every question takes a day to answer. There are good offshore developers too, so compare what's included, not just the rate.

Try the cost calculator

Our free cost calculator gives a rough range and timeline based on project type, complexity, integrations and login needs. No email needed. It's a starting point for your budget, not a quote.

For your IT person

• Typical stack: Next.js and React, or ASP.NET Core and Blazor, with SQL Server, Azure SQL or PostgreSQL.
• Hosting on Azure or AWS.
• Logins, payments and email use established providers rather than custom code.
• Integrations with Xero, MYOB, ServiceM8, simPRO and Stripe use their official APIs.
• Automated tests and deployment are set up from the start, so later changes are cheaper and safer.

Get a real number

The only reliable price is a fixed quote. For bigger projects, that starts with a paid discovery of 1 to 2 weeks, costing AU$2,500 to $8,500, where we work out exactly what to build. Then you get a fixed quote.
