Custom software development typically costs between $25,000 and $75,000 for a focused MVP, $75,000 to $250,000 for a full web or SaaS platform, and $250,000 or more for complex enterprise systems. Where your project lands depends on scope, integrations, design, compliance needs and who builds it.
These are broad industry ranges, not a quote. This guide explains what sits behind them so you can estimate your own budget, compare proposals fairly and avoid the costs that catch most first-time buyers out.
Typical custom software costs by project type
The table below shows common ranges for projects built by an experienced team. Treat them as a starting point for conversations, not fixed prices.
| Project type | Typical range | Typical timeline |
|---|---|---|
| Prototype or proof of concept | $10,000 – $30,000 | 3 – 6 weeks |
| MVP (minimum viable product) | $25,000 – $75,000 | 2 – 4 months |
| Web platform or SaaS product | $75,000 – $250,000 | 4 – 9 months |
| Mobile app (iOS and Android) | $50,000 – $200,000 | 3 – 8 months |
| Enterprise system with many integrations | $250,000+ | 9 months + |
What drives the cost of custom software?
Almost every estimate comes down to the number of hours needed, multiplied by the rate of the people doing the work. These are the factors that change the hours:
- Scope and complexity – the number of features, user roles, screens and business rules. Complex logic such as pricing engines, scheduling or real-time collaboration adds the most time.
- Integrations – each connection to an ERP, CRM, payment provider or third-party API needs building, testing and error handling. Poorly documented legacy systems cost more.
- Design – a custom UX and design system costs more up front than an off-the-shelf UI kit, but usually pays back in usability and conversion.
- Platforms – supporting web, iOS and Android multiplies effort unless you use a cross-platform approach.
- Data and AI features – data migration, analytics and AI features add discovery, testing and infrastructure work.
- Security and compliance – requirements such as GDPR, HIPAA, SOC 2 or PCI DSS add architecture, testing and documentation effort.
- Team location and seniority – rates vary widely by region and experience.
Developer rates by region
Hourly rates for experienced development agencies vary by market. Common ranges are:
- North America: roughly $100 – $200 per hour
- Western Europe and the UK: roughly $80 – $150 per hour
- Eastern Europe: roughly $40 – $80 per hour
- South Asia: roughly $25 – $50 per hour
The lowest rate is rarely the lowest total cost. A senior team that ships the right thing first time often costs less overall than a cheaper team that needs rework.
Where the budget goes: cost by project phase
- Discovery and planning – requirements, user journeys, technical architecture and a prioritised backlog. This is the cheapest place to find mistakes.
- UX and UI design – wireframes, prototypes and the visual design system.
- Development – front end, back end, APIs and integrations. Usually the largest share of the budget.
- Quality assurance – automated and manual testing across devices and edge cases.
- Deployment and launch – infrastructure, CI/CD pipelines, monitoring and go-live support.
The ongoing costs most budgets forget
Launch is the start of a product's life, not the end of its costs. Plan for:
- Maintenance and support – a common rule of thumb is 15–20% of the initial build cost per year for bug fixes, security updates and dependency upgrades.
- Hosting and infrastructure – cloud servers, databases, storage, CDN and monitoring, which grow with usage.
- Third-party services – licences and API fees for email, payments, maps, AI models and analytics.
- New features – most successful products keep evolving based on user feedback.
Our support and maintenance and monthly retainer plans exist to make these costs predictable.
Fixed price vs time and materials vs dedicated team
| Pricing model | Best for | Watch out for |
|---|---|---|
| Fixed price | Small, well-defined projects | Change requests and padded estimates |
| Time and materials | Evolving products and MVPs | Needs clear priorities and regular reporting |
| Dedicated team or retainer | Long-term products and ongoing roadmaps | Requires steady work to use the capacity well |
How to reduce cost without cutting quality
- Start with an MVP that solves one core problem well, then invest based on real usage.
- Invest in discovery – clear requirements are the single best protection against overruns.
- Buy what is not your advantage – use proven services for payments, authentication and email, and build what makes you different.
- Choose a maintainable stack that is widely used and easy to hire for.
- Automate testing and deployment early so every later change is cheaper and safer.
Build or buy: when is custom software worth it?
Off-the-shelf software is faster and cheaper when your process is standard. Custom software is worth the investment when the software is your competitive advantage, when off-the-shelf tools force costly workarounds, when you need to connect many systems, or when per-user licence fees outgrow the cost of owning your own platform. We explore this in more depth in why custom software.
How to get an accurate quote
The more clearly you describe the project, the more accurate and comparable your quotes will be. Prepare:
- The business problem and how you will measure success.
- The main user types and the key things each needs to do.
- Must-have versus nice-to-have features.
- Systems the software must integrate with.
- Any compliance, security or hosting requirements.
- Your target launch date and budget range.

Frequently asked questions
How much does a custom software MVP cost?
A focused MVP built by an experienced team typically costs between $25,000 and $75,000 and takes two to four months. The final cost depends on the number of features, integrations and platforms the first version needs.
Why do quotes for the same software project vary so much?
Quotes differ because teams interpret scope differently, work at different rates and seniority levels, and include different amounts of design, testing and project management. Comparing quotes against the same detailed brief makes them much easier to compare.
How much does it cost to maintain custom software?
A common rule of thumb is 15–20% of the initial build cost per year for maintenance, security updates and small improvements, plus hosting and third-party service fees that grow with usage.
Is custom software cheaper than SaaS subscriptions in the long run?
It can be. When per-user or per-transaction fees grow large, or when workarounds for off-the-shelf tools cost significant staff time, owning a custom platform can cost less over several years. For standard processes, off-the-shelf software is usually cheaper.
How long does custom software development take?
A prototype can take a few weeks, an MVP usually two to four months, a full web or SaaS platform four to nine months, and enterprise systems nine months or more, depending on scope and integrations.
