How we work

A straightforward way to build software

  1. 01

    Talk

    A conversation about what you need, what already exists and what a good result looks like.

  2. 02

    Plan

    We agree scope, approach and milestones in writing, with the trade-offs made explicit.

  3. 03

    Build

    Short cycles with working software at the end of each one, so you see the real thing early.

  4. 04

    Launch

    Deployment, documentation and handover. Then ongoing work, or a clean handoff to your team.

Questions

Hiring a software development partner

What does Code Sage Labs do?

Code Sage Labs is a software development company in Colombo, Sri Lanka. We build custom web and mobile applications, backend systems and APIs, integrations between business systems, AI features and cloud infrastructure, and we take over and improve software that already exists.

Do you work with businesses in Sri Lanka?

Yes. Our first projects were for businesses in Sri Lanka, and we still work with Sri Lankan companies directly, in person in Colombo where that helps.

Can companies outside Sri Lanka outsource software development to you?

Yes. We work remotely with businesses and agencies in any country as an offshore development team. Our working day (UTC+5:30) overlaps Asia and the Middle East fully, Europe in the morning and Australia in the afternoon, and we schedule calls for the Americas early or late.

Do you offer white-label development for agencies?

Yes. Agencies bring us in for client projects that need development, integrations, backend work or AI. The agency stays client-facing, and we can work under its name.

How do projects start, and how are they priced?

A conversation about what you need, then a written scope with the approach and milestones before any work starts. Work is priced as a fixed-scope project or as ongoing monthly work, depending on what fits.

Who owns the software you build?

You do. The source code, infrastructure definitions and deployment pipelines belong to you, and we document the work so your own team or another vendor can continue it.
