How much does custom software development cost?

Custom software projects at customsoftware.agency typically start from $5,000 for focused web applications and scale to $50,000+ for enterprise platforms. Every project begins with a free discovery call where we scope your requirements and provide a fixed-price proposal — no hidden fees, no surprise invoices.

Do you sign NDAs before discussing a project?

Yes, absolutely. We sign a mutual NDA before any detailed project discussion. Your idea, business logic, and proprietary data are protected from the very first conversation.

Who owns the code and IP when the project is done?

You do — 100%. Full intellectual property ownership is transferred to you on final payment. We retain no rights to your codebase, data, or product. This is written into every contract.

Custom Software Built to Scale

Q: How long does it take to build custom software?

A focused MVP or web application typically takes 6–12 weeks from kickoff to launch. Larger enterprise platforms run 3–6 months. We work in two-week sprints so you see real progress continuously, not just at the end.

Q: Do you work with startups or only enterprise companies?

We work with both. Around half our projects are with early-stage startups building their first product, and the other half are with established businesses replacing legacy systems or adding new capabilities. What matters is that you have a clear problem to solve — not your company size.

Q: What happens after the software launches?

Every project includes a 30-day post-launch support period at no extra cost. After that, we offer flexible retainer plans for ongoing maintenance, feature development, and infrastructure monitoring. You're never left with a finished product and no one to call.

We are a custom software agency specialising in scalable web applications, cloud infrastructure, and product design — built for teams that can't afford downtime or technical debt.

How We Deliver Software Projects

A repeatable, transparent engineering process — so you always know what's being built, why, and when it ships.

01 / Architecture

System Design & Scalability Planning

Before we write a single line of code, we map out data flows, API contracts, and capacity requirements — so the system scales with your growth, not against it.

02 / Development

Agile Development with Full Test Coverage

Two-week sprints, daily standups, and peer-reviewed pull requests. Every feature ships with unit tests, integration tests, and automated CI checks — no exceptions.

03 / Launch

Zero-Downtime Deployment & Ongoing Support

Blue-green deployments to hardened cloud environments, with real-time monitoring, automated rollbacks, and post-launch support built into every engagement.
