(04)How we work

From first call to production.

A delivery process designed so there are no surprises: clear scope up front, working software every two weeks, and a clean handover at the end.

2-week sprintsLive demosFixed estimatesCI / CDYou own the IP
  1. Step 01

    Discover

    A free discovery call, then a written scope with a fixed estimate. You see the full range before you commit to anything.

    You get: Scope & estimate

  2. Step 02

    Design

    Architecture, data model and clickable prototypes, reviewed with your team before a line of production code is written.

    You get: Prototype & architecture

  3. Step 03

    Build in sprints

    Two-week sprints with live demos. You see working software every fortnight, never a black box.

    You get: Working increments

  4. Step 04

    Launch & support

    CI/CD, monitoring and handover docs. We stay on for maintenance, or your team takes over. Your code, your repositories.

    You get: Production + handover

(07)FAQ

Something else on your mind? info@vennisys.io

01

What software development services does Vennisys offer?

Vennisys delivers custom ERP systems, HIPAA-compliant healthcare platforms, e-commerce sites, enterprise web applications, mobile apps, cloud and DevOps engineering, legacy system modernisation and technology consulting. We work across the full lifecycle, from architecture and design through development, deployment and ongoing support.

02

How much does custom software development cost?

Cost depends on scope, integrations and compliance requirements. Smaller web applications and internal tools typically start in the low five figures, while multi-module ERP or regulated healthcare platforms run considerably higher. We provide a fixed written estimate after a free discovery call, so you see the full range before committing.

03

How long does it take to build custom software?

A focused MVP or internal tool usually ships in six to twelve weeks. Larger enterprise platforms such as ERP or patient management systems generally run four to nine months, delivered in production-ready increments so you get working software early rather than waiting for one large release.

04

Do you work with international clients?

Yes. Vennisys is based in Colombo, Sri Lanka and works with clients worldwide, with overlapping hours across European, Middle Eastern, Asian and Australian time zones. All communication, documentation and code review is conducted in English.

05

Who owns the source code and intellectual property?

You do. Full intellectual property and source code ownership transfers to your company on final payment, delivered through your own repositories. We do not retain licensing claims over work built for clients.

06

Do you provide support and maintenance after launch?

Yes. We offer ongoing maintenance agreements covering security patching, dependency upgrades, monitoring, bug fixes and feature development. Every project also ships with handover documentation so your internal team can take over at any point.

07

What technologies does Vennisys use?

Our core stack is React, Next.js, TypeScript, Node.js, Python and FastAPI, backed by PostgreSQL, MongoDB and Redis, deployed on AWS or Google Cloud with Docker, Kubernetes and automated CI/CD pipelines. We select the stack to fit the problem and your team's long-term maintainability, not fashion.
