CentriWebApp development cost in Australia comes down to how many hours the build takes multiplied by the developer’s rate, and the hours are set by a short list of choices: which platforms, how many types of user, what the app connects to, and whether it takes payments. Two apps that sound alike can differ several times over in price, so the useful thing to know is what moves the number, then get quotes against one written brief.
We have not put price bands in this article. Any range we printed would be a guess about your app. What follows is how the price is built, the fixed costs that do have published figures, and how to get quotes from app developers in Australia that you can compare. For the wider picture on software quotes, see our guide to what custom software costs in Australia.
What app development cost in Australia is made of
Almost every quote is built the same way, whether it comes from a freelancer, a studio or an offshore team:
- Discovery and design: working out what the app must do and drawing the screens.
- The app itself: the screens people tap through on the phone or in the browser.
- The back end: the server, database and admin area that hold the data and let your staff manage it. People often forget this part, and it is frequently the bigger half.
- Connections: links to your CRM, accounting, calendar, payments or job management software.
- Testing and release: trying it on real devices and getting it through app store review.
- A margin for unknowns, whether it is stated or built into the rate.
To read any quote, multiply the hours for each part by the rate. If a quote has no breakdown, ask for one. A single total tells you nothing about where the money goes or what to cut.
Which platforms: iPhone, Android, both, or a web app
This is the first decision and one of the biggest. The options are:
- One native platform (iPhone only, or Android only). Fewer hours, but you leave out part of your market.
- Both, from one shared codebase using a cross-platform framework. Usually fewer hours than two separate apps, with some limits for very device-specific features.
- Two separate native apps. The most hours, and two codebases to maintain.
- A web app that runs in the browser and can be saved to the home screen. No app store, one codebase, and updates go live straight away.
Apple’s App Store Review Guidelines say an app should offer more than a repackaged website, and that one which is not useful or app-like may not be accepted. If your app is mostly forms, lists and logins, a web app may do the job for less. Our guide to web app vs mobile app walks through that choice.
Features that move the price most
| Choice | Fewer hours | More hours |
|---|---|---|
| Platforms | A web app, or one platform | Two separate native apps |
| Types of user | One, such as customers | Several, each with their own screens and permissions |
| Accounts and login | None, or a simple email login | Roles, approvals, single sign-on |
| Connections | None, or one well-documented system | Several systems that must stay in sync both ways |
| Payments | None, or a link to a hosted checkout | Subscriptions, refunds and in-app purchases |
| Offline use | Needs a connection | Works offline and syncs later |
| Design | A clean standard look | Custom illustration and animation |
The two that catch people out are user types and connections. Every extra type of user, say a customer, a staff member and a manager, adds a set of screens and permission rules. Every connection to another system adds work to handle errors, duplicates and the other system changing.
A worked example with your own figures: list every screen for each type of user, then ask the developer to estimate hours per screen and per connection. If they estimate 20 screens and three connections, you can see at once what dropping one connection or one user type would save.
Ways to bring the number down
- Use a ready-made admin area or your existing CRM for staff tasks, so only the customer side is custom.
- Take payments through a hosted checkout from your payment provider instead of building your own payment screens.
- Leave version two features in a list, and build them only once people use version one.
- Bring a clickable prototype. Developers can estimate far more tightly from screens they can tap through than from a written idea.
Costs after launch: stores, updates and hosting
Some running costs have published figures, as at November 2026. Check each page for current amounts.
- Apple: the Apple Developer Program page showed a $99 annual membership. The page shows the $ sign without naming a currency. Apple’s membership comparison says membership is needed to distribute apps through the App Store.
- Google Play: Google’s developer account help page says there is a US$25 one-time registration fee.
- Commission on digital sales: Apple’s Small Business Program offers a 15% commission on paid apps and in-app purchases for developers with up to US$1 million in proceeds in the prior calendar year. Google’s service fee page lists different rates for users in Australia, the United States, the United Kingdom, the EEA and Japan, starting at 10% plus a 5% billing fee for auto-renewing subscriptions.
For many service businesses the commission does not apply. Apple’s guidelines say that when people buy physical goods or services used outside the app, the app must use other payment methods, such as Apple Pay or card entry. A trades booking app or a clinic appointment app usually falls on that side, and pays its normal card processing fees instead.
The costs without a published figure are often larger:
- Updates for new phone operating systems, which Apple and Google release regularly and which can break older apps.
- Hosting for the back end and database.
- Fixes and small changes once real people use it.
- Security updates for the libraries the app is built on.
Our guide to software maintenance cost covers how to budget for these.
Fixed price or time and materials
A fixed price suits a small app with a clear brief: you know the number, and the developer carries the risk of going over, which is priced in. Time and materials suits a larger or less certain build: you pay for hours used, and you can change direction, but the total can move. Many projects use stages, with a fixed price for discovery and design, then a quote for the build once the screens are agreed.
Getting quotes from app developers in Australia you can compare
Quotes only compare when they are priced against the same brief. Before you ask anyone, write down:
- Who uses the app, and what each type of user needs to do.
- Which platforms, and why.
- Every system it must connect to.
- Whether it takes payments, and for what.
- What happens after launch: who maintains it, and how changes are requested.
Our guide to writing a software requirements document gives a template. Then ask each developer the same questions: is the back end included, how many rounds of changes are in the price, who owns the code and the store accounts, and what support costs after launch. Ask whether the quote includes GST.
A local developer is not automatically dearer than an offshore one once management time and time zones are counted. Our guide to offshore software development covers that comparison.
Where to start
- Write one paragraph on the job the app does for the business: save time, bring in money, or keep customers you already have. If it does none of those, it can wait.
- Check whether existing software, or a web app, already does most of it.
- Cut the first version to one type of user and the one connection that matters most.
- Get two or three quotes against the same written brief.
If you would like a second opinion on a brief or a quote, CentriWeb’s custom software team builds web apps and internal tools and looks after them after launch, and we will say so when an off-the-shelf product already covers the job.
