Software built around how your business works.

SaaS platforms, client portals, dashboards, point-of-sale and internal tools, including replacing an old system and moving its data. Every project starts with a discovery workshop, so the scope and the price are fixed before the build.

Good for

  • A process that lives in spreadsheets, chats and paper
  • An old system that holds you back
  • A product or platform you want to bring to market
  • Tools that should talk to each other and do not

Included

  • Discovery workshop
  • Architecture and data model
  • Web platforms and dashboards
  • APIs and integrations
  • Migration from old systems
  • Automated tests
  • Documentation and handover

How it runs

How every project runs. Five steps, the same for every service.

  1. Step 01

    Call

    30 min, free

    You tell us what you need and how your business works. We ask the questions that matter for the build.

  2. Step 02

    Concept

    or discovery

    For websites and shops, we design a concept first, at no cost. Apps and custom software start with a paid discovery workshop.

  3. Step 03

    Offer

    one page

    Three options, one recommendation, fixed prices and the date the offer is valid until.

  4. Step 04

    Build

    fixed price

    We design, build and test, and you review the work before anything goes live.

  5. Step 05

    Launch

    and care

    We launch, hand over the admin and start the maintenance plan. From then on, you have someone who answers.
