Cost by Project Type

Custom application costs vary wildly by project type. An MVP might cost $20,000; an enterprise system might cost $500,000. These ranges reflect realistic budgets in the Australian market for experienced developers. They are not guarantees—your project could cost more or less depending on complexity and requirements.

MVP (Minimum Viable Product): $15,000–$50,000

An MVP is a simplified version of your product with core features only. No polish, no edge cases, just enough to validate your idea with real users.

Examples: a basic SaaS landing page with signup flow; a simple content management system; a mobile app prototype with one core feature. The goal is speed to market and learning.

At the low end ($15,000), you're using templates, no-code tools, or a freelancer with tight scope. At the high end ($50,000), you have a small team, custom design, and a few integrations.

Timeline: 6–12 weeks for a skilled developer working full-time.

Internal Business Tool / Admin Panel: $20,000–$80,000

These are tools for your internal team: employee directories, expense reporting, project management, inventory systems, or data dashboards. They're not customer-facing.

Since users are internal and tolerant of quirks, these can be simpler than customer-facing apps. However, they often need to integrate with existing systems (databases, accounting software, ERPs).

At $20,000–$30,000, you get a basic tool with standard features. At $60,000–$80,000, you have advanced features, sophisticated reporting, and complex integrations.

Timeline: 8–14 weeks.

Customer-Facing SaaS Application: $50,000–$200,000+

A SaaS (Software-as-a-Service) platform your customers pay to use. Examples: project management tool, CRM, email marketing platform, accounting software. These require polish, reliability, and scalability.

Budget includes: professional design, robust error handling, multi-user support, data security, payment processing, customer support infrastructure, and extensive testing.

At $50,000–$80,000, you get a functional but simple SaaS with basic features (Kanban boards, user management, simple reporting). At $150,000–$200,000+, you have sophisticated features, advanced analytics, integrations, and mobile support.

Complexity drivers: number of user types (customers vs. admins vs. resellers), data complexity, real-time features, and integrations all push costs upward.

Timeline: 4–9 months for a moderately complex SaaS.

Mobile Application (iOS/Android): $60,000–$150,000+

Native mobile apps are more expensive than web apps because you need native expertise (iOS developers know Swift; Android developers know Kotlin). Or you use cross-platform frameworks like React Native or Flutter (cheaper but sometimes less polished).

A simple utility app (calculator, to-do list) might cost $30,000–$50,000. A functional business app (expense tracking, client directory, field service app) costs $60,000–$100,000. A sophisticated app with real-time features and offline support costs $100,000–$200,000+.

Additional costs: iOS developer account ($99/year), Google Play account ($25 one-time), app store review time and rejections, and OS-specific bugs and testing.

Timeline: 3–8 months for a first mobile app.

E-Commerce with Custom Features: $30,000–$100,000

If you use Shopify, WooCommerce, or BigCommerce, a basic store with custom features costs $10,000–$30,000. If you build fully custom, costs jump to $50,000–$150,000+.

The custom build option gives you full control but requires building core functionality from scratch: cart, checkout, inventory management, order processing, payment integration.

Budget varies by: number of products (5 vs. 50,000), payment gateways (Stripe, PayPal, local methods), shipping integrations, custom reporting, and supplier integrations.

Timeline: 2–6 months for a custom build.

Enterprise Integrations: $40,000–$200,000+

Connecting multiple enterprise systems: ERP, CRM, accounting software, legacy systems. These projects are complex because you're integrating other people's software, not building from scratch.

Challenges: unclear API documentation, strict security requirements, data migration from legacy systems, custom workflows, and testing against multiple systems.

Budget heavily for: discovery and scoping (20% of total cost), data mapping and validation, error handling and rollback, security and audit trails, and extensive testing.

Timeline: 2–12 months depending on number of systems and data volume.

Data Dashboards: $20,000–$80,000

Business intelligence dashboards that visualize data from multiple sources. Used for reporting, analytics, and decision-making.

Simple dashboards (5–10 charts, basic filters) cost $20,000–$35,000. Complex dashboards (50+ visualizations, advanced filtering, drill-down capabilities) cost $60,000–$100,000+.

Heavy lifting is in data modeling and optimization. Getting data from messy sources, cleaning it, aggregating it, and querying it efficiently is the bulk of the work.

Tools like Tableau or Power BI can reduce cost ($5,000–$15,000 for implementation) but give you less control and flexibility than a custom build.

Timeline: 1–4 months.

What Pushes Costs to the Higher End

Complexity: Multiple user types, sophisticated workflows, real-time features, offline support. Complexity adds 30–50% to costs.

Integrations: Each third-party integration adds 15–25% to the cost. Connecting to Stripe, Salesforce, Slack, and your legacy database adds up.

Data volume: Applications that handle millions of records or gigabytes of data require optimization, caching, and database expertise. This adds 20–40%.

Performance requirements: If your app must handle 10,000 concurrent users or respond in under 100ms, engineering costs increase significantly.

Compliance: GDPR, HIPAA, PCI-DSS, SOC 2—each adds complexity and cost. HIPAA compliance for a healthcare app might add $20,000–$50,000 to the budget.

Mobile support: Building for iOS and Android doubles the cost vs. web-only. Cross-platform frameworks (React Native) cost less than native but more than web.

Custom design: Template-based design costs $2,000–$5,000. Custom brand design costs $5,000–$20,000+. Sophisticated interactions and animations add more.

Why You Can't Get a Meaningful Quote Without Scoping

"How much does a web app cost?" is unanswerable. It's like asking "How much does a house cost?" A shed costs $5,000. A modest home costs $300,000. A mansion costs $5,000,000.

A quote requires understanding: what features? how many users? which integrations? what's the timeline? what's the data volume? how mission-critical is it?

Any developer who quotes without scoping is guessing or padding aggressively. Ask for a scoping engagement (1–2 weeks, $2,000–$5,000) to produce a detailed estimate. It's money well spent.

Project Type Cost Comparison

The Role of Team Size in Cost

A solo freelancer building a $50,000 project might take 6 months. A team of 3 at an agency might finish in 3 months but charge $50,000/month. The total cost is the same, but you choose your timeline.

Freelancers are cheaper on hourly rate but slower. Agencies are faster but more expensive. For time-sensitive projects, paying more to go faster makes sense. For flexible timelines, a slower freelancer is fine.

Common Quote Red Flags

"$10,000 for a fully custom SaaS app." Unrealistic. Either the scope is incredibly limited or the quality will be poor. Be suspicious.

"We can build it in 2 weeks." For what scope? If you need a sophisticated application, 2 weeks is comedy. Push back on timelines that sound too good.

No mention of scope, integrations, or design. The quote is a guess. Ask for itemized details.

"Price depends on the complexity." That's true, but it's not a quote. Get specific estimates once you define what "complex" means.
