Services

Four ways to work with us

Every engagement starts with a paid discovery or audit, so you get a written plan and a fixed price before committing to a build.

Services & process

  • E-commerce builds

    Headless or themed storefronts on Shopify or a custom stack, built for mobile buyers and measured on conversion, not on how the homepage looks in a pitch deck.

    From $38,000

  • Web apps and booking

    Customer-facing web apps with real business rules: booking, quoting, accounts and payments. Typed end to end and tested where mistakes cost money.

    From $45,000

  • Internal tools

    Dashboards and back-office tools that replace spreadsheets and copy-paste. Designed for people who use them all day, with keyboard shortcuts and sensible permissions.

    From $28,000

  • Performance rescues

    A fixed-length engagement to find why your site or app is slow, fix the worst causes alongside your team and leave guardrails so it stays fixed.

    From $18,000

Kind words from clients

They asked for our analytics before they asked about colours. Every decision in the rebuild was tied to a number, and the numbers moved.

  • “The handover week was the best part. Our two developers now own the system, and the runbook has already saved one Saturday.”

  • “Fixed price, weekly demos, no surprises. When the practice software API turned out worse than expected, they told us that week and showed us the plan B.”

  • “Six weeks, and our Wednesday night support queue went quiet. They left us with budgets in CI that we still follow every sprint.”
