Custom Software Development Services
Off-the-shelf software forces your business to work the way the vendor imagined. Custom software works the way you actually operate. StellarCode designs and builds bespoke systems — ERPs, CRMs, booking engines, logistics dashboards, client portals — around your exact workflows, integrations and growth plans.
Our senior engineering team is based in Sri Lanka, which means you get the same architecture quality, code review discipline and delivery process you would expect from a top US or European consultancy, at a fraction of the rate. Every project starts with a free consultation and ends with a fixed, transparent quote — no hourly billing surprises.
What you get
Discovery & technical specification
We map your workflows, integrations and constraints into a written spec and architecture plan you own — before any code is written.
Full-stack engineering
Production-grade backend, frontend and database work with automated tests, code review and CI/CD from day one.
Third-party integrations
Payments, accounting, ERPs, messaging, government e-services — we connect your system to the tools your business already runs on.
Migration from legacy systems
Structured data migration and phased rollouts that replace spreadsheets or ageing software without stopping your operations.
Security & access control
Role-based permissions, audit logs, encrypted data at rest and in transit, and OWASP-aligned secure coding practices.
Ongoing support & evolution
Post-launch SLAs, monitoring, and a roadmap process so the system keeps pace as your business changes.

Custom Software Development — FAQ
How much does custom software development cost?
Most StellarCode custom software projects land between $8,000 and $60,000 depending on scope — typically 40–70% below what US, UK or GCC agencies quote for the same system, because our engineering hub is in Sri Lanka. After a free consultation we give you a fixed quote, so the price you approve is the price you pay.
How long does a custom software project take?
A focused internal tool or portal usually ships in 6–10 weeks. Larger systems such as a custom ERP or multi-role platform typically take 3–6 months. We work in weekly sprints with demos, so you see working software from the second week, not just at the end.
Who owns the source code and IP?
You do — fully and unconditionally. Every contract assigns complete ownership of the source code, designs and documentation to you on payment. The code lives in a repository you control from the first sprint.
Can you take over or extend an existing system?
Yes. Around a third of our engagements start with a codebase another team built. We begin with a paid technical audit (credited against the project if you proceed), stabilise what exists, then extend it — or plan a phased rewrite if the foundations are beyond saving.
