Platform Engineering

Shopify Apps & Plugins

Public and custom apps, App Store review handled, Plus checkout extensions and theme app blocks.

Shopify moves its platform forward every quarter. An app that was correct a year ago may now be using deprecated APIs, injecting script tags into themes, or relying on checkout.liquid — all of which Shopify is retiring.

Current platform, from day one

We build on the current app template, use theme app extensions instead of editing theme code, and move checkout logic into Checkout UI extensions and Functions. The result passes App Store review and keeps working through API version changes.

Where we usually help

  • Plus merchants moving off checkout.liquid before the deadline
  • Brands that need ERP or PIM data reflected in Shopify in minutes, not hours
  • SaaS companies launching a public Shopify app for the first time

    API-version upgrades and support on a monthly retainer.

Questions we get asked

Can you migrate our checkout.liquid customisations?

Yes. We map each customisation to Checkout UI extensions or Functions and flag anything that has no equivalent before we start.

Do you build public apps for our own SaaS?

Yes, including billing, onboarding and the App Store listing.

One call, and you will know if we are a fit.
