Both answers are describing the same market. The difference is what happens before the quote: an open-ended brief genuinely can cost anywhere in that range, so agencies price the uncertainty. A disciplined scope collapses the range. This guide shows the real numbers at each tier, what actually moves an app between them, and how to keep a first build near the bottom of the range without shipping something throwaway.
Perth app development prices: what we charge
These are the published fixed packages we sell — the same numbers on our pricing page, where the smaller ones can be secured directly through Stripe. No range theatre: the "from" tiers move only when your scope adds named features, and the blueprint exists precisely so that conversation happens before the build is priced.
| Package | Price | Timeline | Best for |
|---|---|---|---|
| Product blueprint | $2,500–$3,500 fixed | 1–2 weeks | Paid discovery sprint: scope, data model, delivery plan, and a build price you can hold us to |
| MVP / proof of concept | from $12,000 | 6–10 weeks | Validating a product with the smallest build that gives real answers |
| Cross-platform app | from $18,000 | 10–14 weeks | One codebase shipping to both iOS and Android |
| Full platform | from $18,000 | 10–16 weeks | SaaS products, dashboards, and operational systems with backends |
| Advanced app | from $32,000 | 14–20 weeks | Real-time features, payments, offline sync, and an admin portal |
Every package includes product direction, UX and UI design, engineering, testing, and deployment to production — the phases many quotes bill separately as discovery and design before development pricing even starts.
Why most Perth quotes say "$40,000 to $250,000+"
The wide range is not dishonest — it is what pricing an undefined brief looks like. One established Perth app agency publishes exactly that range for custom apps, with discovery billed at $3,000–$8,000+ and UX/UI design at $5,000–$15,000 before development is priced. Add those phases and a mid-range custom build lands at $60,000–$120,000, which matches what national agencies charge.
The practical problem is that a range that wide cannot be planned against. You cannot take "$40,000 to $250,000" to a business case, a grant application, or an instant asset write-off decision. Our answer is to sell the scoping phase as its own fixed product — the blueprint — so the number that comes out of it is a commitment, not an estimate that resets once work starts.
What actually drives an app’s cost
Screen count is the metric buyers focus on and the one that matters least. These are the levers that actually move an app between tiers:
- Backend complexity — an app that stores and syncs shared data needs an API, database, and hosting; a self-contained tool does not.
- Real-time features — chat, live tracking, and collaborative editing multiply backend and testing effort.
- Payments — checkout, subscriptions, and payout flows add integration, compliance, and edge-case work.
- Offline behaviour — caching and conflict resolution when connectivity drops is one of the most underestimated line items.
- Integrations — every third-party system (accounting, CRM, government APIs) adds authentication, mapping, and failure handling.
- Admin tooling — the customer-facing app is often half the product; the back office that runs it is the other half.
- Accounts and compliance — authentication, roles, privacy obligations, and audit trails scale with how sensitive the data is.
How to keep a first build near $12,000–$20,000
Most first versions fail commercial planning by carrying features the launch does not need. The discipline that keeps a build in the MVP tier:
- Start from the one workflow that proves the product, and cut everything that does not serve it — feature two can be version two.
- Default to cross-platform. Native iOS and Android as separate builds nearly doubles cost, and few first products need platform-specific performance.
- Buy, don’t build, the commodity parts — authentication, payments, analytics, and notifications all have services that cost less than a week of custom engineering.
- Do the blueprint first. Two weeks of scoping is the difference between a fixed price and a range, and its cost is small against a five-figure build.
- Defer the polish that does not change the answer — an MVP validating demand does not need the animation budget of a consumer flagship.
The ongoing costs no quote should hide
After launch, three cost lines continue whether or not you keep building: store fees (Apple’s developer program is US$99 per year; Google Play is a one-off US$25), hosting and backend services that scale with usage, and maintenance — operating system updates, dependency patches, and small fixes. Ask any developer to name these before you sign; a quote that ignores them is quoting a different product than the one you will own.
Frequently asked questions
How much does an MVP app cost in Perth?
From $12,000 with a 6–10 week timeline, covering design, build, testing, and deployment of the smallest product that gives real market answers. A $2,500–$3,500 blueprint sprint beforehand fixes the scope and the price.
Does one price cover both iOS and Android?
Yes — our cross-platform package (from $18,000) ships both platforms from one codebase. Separate native builds are reserved for products that genuinely need platform-specific performance, and cost more.
Why are your prices lower than the $40k–$250k quotes?
Mostly scope discipline, not corner-cutting. Wide quotes price an undefined brief plus separately-billed discovery and design phases. Our packages include those phases, and the blueprint defines scope before the build is priced — so the number is smaller and it holds.
What does it cost to keep an app running after launch?
Apple charges US$99/year and Google a one-off US$25 for store access, hosting typically runs tens to hundreds of dollars a month depending on usage, and you should budget for periodic OS-update maintenance. We scope ongoing support per product rather than forcing a generic retainer.
Can I start with the blueprint without committing to a build?
Yes. The blueprint is a standalone fixed-price product — you leave with a scope, data model, delivery plan, and a firm build price you can take to us or to any other developer.

Want a number you can plan against?
Start with a product blueprint — $2,500–$3,500 fixed, 1–2 weeks, and you leave with a scope and a build price that holds whether you build with us or not.
