How we work

Clear before we start, involved until the end.

  1. Step 1

    First consultation

    A free session by phone or WhatsApp. We listen to the problem first, with no obligation.

  2. Step 2

    Estimate and contract

    You receive a time and cost estimate. Scope, schedule, and price are written into the contract before work starts.

  3. Step 3

    Development in stages

    Work is split into stages you can try at each step. Payments follow milestones.

  4. Step 4

    Launch and support

    Once the system is live, we keep handling fixes, security patches, and new features. Monthly or on-demand plans are available.
