Why Netbii

A development partner that is easy to work with

Good software comes from clear communication and honest engineering. This is how we work with every client.

Clear communication

Weekly written updates, a shared task board and calls scheduled around your time zone. You always know what was done and what comes next.

Transparent pricing

Itemised estimates before work starts and no surprise invoices. Any change in scope is priced and agreed in writing first.

You own the code

Source code, designs and infrastructure live in accounts you control, and full intellectual property transfers to you on payment.

Confidential by default

We sign your NDA before discovery, use least-privilege access and keep credentials out of chat and email.

Quality built in

Code review, automated tests and staging environments are part of every project, not an optional extra.

Support after launch

Monitoring, updates and improvements continue after release through a support plan sized to your product.

How we work

A simple, predictable delivery process

Five stages, each with a clear outcome you can review before we move on.

  1. 01

    Discovery

    We clarify goals, users and constraints, then turn them into a scoped plan with a fixed estimate or a team proposal.

  2. 02

    Design

    Wireframes and interactive prototypes let you see and test the product before production code is written.

  3. 03

    Build

    Two-week sprints with a working demo at the end of each one, so you can give feedback early and often.

  4. 04

    Test

    Automated and manual testing across devices and browsers, plus security and performance checks before release.

  5. 05

    Launch & Support

    We deploy, monitor and hand over documentation, then keep improving the product with you.

FAQ

Questions clients ask before we start

How much does a software project cost?
It depends on scope, complexity and the engagement model. Small websites and focused MVPs often start in the low five figures, while larger platforms are priced in phases. After a short discovery call we send an itemised estimate, so you know exactly what is included before any work begins.
How long does it take to build an app or website?
A marketing website usually takes four to eight weeks, and a first version of a web or mobile app typically takes eight to sixteen weeks. We agree milestones up front and show working software every two weeks, so you can see progress throughout.
Do you work with clients in other time zones?
Yes. We work with clients internationally and schedule regular calls inside your business hours. Between calls we keep you updated in writing through a shared task board and weekly progress reports.
Who owns the code and intellectual property?
You do. Code, designs and infrastructure are kept in repositories and accounts you own, and full intellectual property rights transfer to you on payment. We are happy to sign your NDA before discussing your idea.
Can you take over an existing project?
Yes. We start with a code and infrastructure review, share an honest assessment of risks and quick wins, and then agree a plan to stabilise, improve or rebuild the parts that need it.
What happens after launch?
We monitor the release closely, fix any issues and hand over documentation. Most clients continue with a maintenance and support plan that covers updates, monitoring and a monthly allowance for improvements.
