Short answer: custom software built by a professional team in the US or UK typically costs around $30,000–$75,000 for a focused internal tool or MVP, $75,000–$200,000 for a business application or customer portal, and $200,000+ for an enterprise platform with many users, integrations and strict security needs. The biggest cost drivers are scope, integrations, data and security requirements, and the team you hire. For a quick estimate, try our cost calculator.

What affects the cost of custom software?
- Scope and complexity: number of features, user roles, workflows and business rules.
- Integrations: ERPs, CRMs, payment gateways, identity providers and legacy systems.
- Data and migration: moving and cleaning data from spreadsheets or older systems.
- Security and compliance: SSO, audit logs, encryption, GDPR, HIPAA or SOC 2 requirements.
- Platforms: web only, or web plus iOS and Android apps.
- Design: standard admin screens or a polished customer-facing experience.
- Technology: modern stacks such as ASP.NET Core, Node.js or Python, and cloud hosting choices.
- Team location and experience: rates vary widely by region and seniority.
Typical hourly rates by region
| Region | Approximate hourly rate (USD) |
|---|---|
| United States | $100–$200 |
| United Kingdom and Western Europe | $70–$150 |
| Eastern Europe | $40–$80 |
| South Asia | $25–$50 |
Rates are approximate and vary by experience, technology and engagement model.
Where the budget goes
- Discovery and planning (around 5–10%): requirements, workflows, architecture and estimate.
- UI/UX design (around 10–15%): wireframes, prototypes and final designs.
- Development (around 50–60%): front end, back end, integrations and data migration.
- Testing and QA (around 15–20%): functional, security and performance testing.
- Deployment and project management (around 5–10%): releases, training and coordination.
Fixed price vs time and materials
| Model | Best for | Watch out for |
|---|---|---|
| Fixed price | Clearly defined scope, MVPs, first phases | Changes need a change request; scope must be detailed |
| Time and materials | Evolving products and long-term development | Needs regular budget reviews and clear priorities |
| Dedicated team | Ongoing product development and support | Works best with a product owner on your side |
Ongoing costs after launch
- Cloud hosting, databases and backups.
- Third-party licences and APIs.
- Maintenance: security updates, framework upgrades and bug fixes, often 15–20% of the original build cost per year. See our software maintenance services.
- New features as your business grows.
Custom software vs off-the-shelf
Off-the-shelf software is cheaper to start but you pay subscriptions per user forever and adapt your processes to the tool. Custom software costs more upfront, but it fits your exact workflows, integrates with your systems, has no per-user licence fees and becomes an asset your business owns. Many companies start with off-the-shelf tools and build custom software once their processes become a competitive advantage.
How to reduce custom software cost
- Start with an MVP or first phase that solves the most valuable problem. See our MVP development services.
- Write down your workflows and must-have features before requesting quotes.
- Reuse proven components and cloud services instead of building everything.
- Phase complex integrations and nice-to-have features.
- Choose a partner with experience in your technology and industry.

Frequently asked questions
Most custom software costs between $30,000 and $200,000, depending on scope, integrations and security needs. Enterprise platforms can cost more.
Internal tools and MVPs often take 2–4 months, business applications 4–8 months, and enterprise platforms longer, usually delivered in phases.
It is worth it when off-the-shelf tools do not fit your processes, per-user licence costs are high, or the software gives you a competitive advantage.
Expect hosting, licences and maintenance, often around 15–20% of the build cost per year, plus new features over time.
