What does custom software development with ImliStack include?

Custom software development at ImliStack covers discovery, architecture, UI/UX, front-end and back-end engineering, integrations, testing, deployment and post-launch support. We build web platforms, mobile apps and APIs as one system, typically on Node.js, React or Angular, Flutter and MySQL, PostgreSQL or MongoDB, and hand over documented, maintainable code.

Is this for you

Where we usually help

If any of these sound familiar, a short call is the fastest way to find out whether we are the right fit.

  • Off-the-shelf tools force your team into workarounds and spreadsheets
  • You are turning an idea or a manual process into a SaaS product
  • A marketplace, booking or ticketing flow needs payments, roles and real-time updates
  • You need one partner to own web, mobile and back end together

How we work

A delivery approach you can follow

Written plans, visible progress and decisions recorded as we go — so nothing depends on memory.

  1. Discover

    Map users, workflows, data and constraints. Agree scope, risks and what success means.

  2. Architect

    Choose the data model, services and integrations. Document decisions before code.

  3. Build in increments

    Ship working software in short cycles with demos, staging environments and reviews.

  4. Launch & support

    Production rollout, monitoring, fixes and a clear plan for the next iteration.

FAQ

Custom Software Development: common questions

How much does custom software development cost?

Cost depends on scope, integrations and timeline, so we do not publish fixed prices. After a short discovery call we send a written estimate with phases, assumptions and exclusions. Many clients start with a fixed-scope discovery or audit to reduce uncertainty before committing to a full build.

Will we own the source code?

Yes. Code, infrastructure accounts and documentation belong to you. We work in your repositories where possible and transfer everything at handover.

Can you work with our existing team?

Yes. We can lead the build end-to-end or work alongside your engineers, following your branching, review and release process.

Which time zones do you support?

We are based in India (IST) and schedule regular overlap with clients in the UK, Europe, the US and Australia. Communication is asynchronous-first with written updates, plus scheduled calls.
