How much does a custom app really cost in Australia (2025)?

Short answer

For a focused, single-purpose app built well — what most small businesses actually need — the realistic price band in Australia in 2025 is $5,000–$25,000. Genuinely complex multi-system builds run $40,000–$150,000+. Anything between those two tiers is usually overhead, not engineering.

At Warp App Development we work in that lean tier and start at $5,000 per app, subject to scope.

The three tiers (what you're really paying for)

Tier 1 — Lean custom app · $5,000–$15,000

One clear purpose, one or two user roles, modern stack, sensible defaults. Auth, push notifications, payments via Stripe, an admin panel, App Store/Play deployment. Built in 4–8 weeks. This is where Warp lives, and where 80% of small business apps actually belong.

Tier 2 — Mid-market · $25,000–$80,000

Multiple integrations, custom design systems, larger teams, longer cycles. Usually justified by bespoke integrations (legacy systems, hardware, complex billing). Often not justified by a slightly nicer UI.

Tier 3 — Enterprise / agency · $80,000–$250,000+

Account management, formal discovery, brand workshops, RFP processes, large development teams, multiple QA passes. Plenty of real engineering in there — and a meaningful chunk of pure project-management overhead.

Where the money usually goes

• 40–60% — engineering time (the bit you actually want)
• 10–20% — design
• 15–30% — project management, account management, sales overhead
• 5–15% — QA, testing, App Store submission

That middle line is the one to interrogate. A small studio cuts it dramatically because the developer is the project manager is your point of contact.

What changes the price most

1. Number of platforms. One platform vs. iOS+Android+web roughly doubles the build.
2. User roles. Customers + staff + admins triples the screens.
3. Payments & subscriptions. Stripe checkout is cheap; full subscription billing logic isn't.
4. Integrations. Each external system (Xero, MYOB, a legacy CRM, a piece of hardware) adds real time.
5. Design uniqueness. A clean default UI is fast; a custom design language is days of iteration.

Pricing red flags

Three signs a quote is padded: a 30+ slide proposal you didn't ask for, a single multi-month 'phase' with no weekly deliverables, and the phrase "we can't really estimate that yet" combined with a six-figure number.

What you should actually ask a developer

• What's the smallest version of this that solves the problem?
• Can I see your previous shipped apps — live, in the store?
• Will I own the source code and all accounts at the end?
• What's not included at this price?
• How long, end-to-end? In weeks, not phases.
