Custom Shopify apps, built like a software company would.

Every project starts with a written spec: what the app does, who uses it, what data it reads and writes, what happens when something fails, and how we’ll know it works. It comes with a fixed quote or a clear estimate, and you approve it before any code is written. Most disagreements in software come from unwritten assumptions; the spec removes them.

Next we choose the right building block for your custom Shopify apps. Shopify’s app distribution rules matter here: an app built for one store uses custom distribution, needs no App Store review and can’t bill through Shopify’s app billing, while Shopify says apps created directly in the admin are no longer available for new apps. Logic that must run inside Shopify, such as discounts, payment and delivery customizations or cart validation, belongs in Shopify Functions; changes to the checkout page use checkout UI extensions.

Then we build the custom Shopify app, with AI-assisted development and a developer responsible for every line. Modern AI coding tools make it realistic to build things that used to need a large team, faster and for less. They also write confident, wrong code if nobody checks it. So every change is read, tested and reviewed before it’s merged, the same as if a person had typed it. That combination is why we can say yes to most custom requests and still stand behind the result.

We ship like a software company. The code lives in version control (your repository, or ours with access for you); there’s a development store or staging setup for testing; critical paths have automated tests; API keys and passwords stay out of the code; and the app requests only the API access scopes it needs. Shopify’s API rate limits and webhooks are handled properly, so the app keeps working on your busiest day.

Launching custom Shopify apps is planned, not hoped for: a test on the real store at a quiet time, a way to switch the feature off, and monitoring for errors after release. You get documentation in plain English (what the app does, how to use it, how it’s deployed) and ownership of the code. Nothing is locked to us.

After launch, custom Shopify apps need care. Shopify releases new API versions on a schedule and retires old ones, so we keep custom apps current as part of a care plan or a small yearly maintenance agreement. Because we also run marketing, we build with tracking and reporting in mind from day one. Shopify releases new API versions on a quarterly schedule, and Shopify CLI blocks deploys that target versions older than 12 months, so we keep custom code on a supported version. Speed is judged against Google’s Core Web Vitals thresholds: main content within 2.5 seconds, a response to input within 200 milliseconds and layout shift of 0.1 or less.
