About

A small team. Senior hands on every line.

Metack designs and builds software for companies whose systems have to talk to each other: ERP and CRM, shops and catalogues, data platforms and AI agents. You work with the people who write the code, from the first workshop to the day it goes live.

One team, start to finish

The architect who scopes the work stays to build it. No hand-offs between sales, design and delivery.

Fixed scope, stated up front

Every engagement starts with a written scope, phases and a price, so you know what you are buying before work begins.

Built to be handed over

Documented, tested and yours: code, infrastructure, documentation and the training to run it without us.

Process

How an engagement runs

  1. 01

    Workshop

    Goals, users and constraints; a look at your real data.

  2. 02

    Scope and price

    A written scope in phases, with options priced separately so you choose what to add.

  3. 03

    Build in phases

    Each phase ends in a working release you can try on your own data, not a status report.

  4. 04

    Launch and care

    Tests with your team, training, launch, and support for as long as you want it.
