Shopify app development
Public App Store apps and private apps for single merchants. We've taken our own product through Shopify's review process and onto the App Store, so we know where submissions fail before yours does.
When this is the right call
Signs you need this
No existing app does the thing
You've been through the App Store and the closest match is 70% right. The last 30% is where your margin lives, and no amount of configuration gets you there.
You want to sell the app, not just use it
You've spotted a gap in a category and want a public listing with billing, plan tiers and usage limits — not an internal tool.
A previous build stalled in review
App Store review rejects for reasons that aren't obvious: missing GDPR webhook subscriptions, unhandled uninstall, session token problems. These are fixable, quickly, by someone who has hit them before.
Scope
What's included
- Embedded admin UI in Remix and Polaris, so it looks native inside Shopify
- OAuth, session tokens and webhook handling done properly
- Shopify Functions for discounts, payment and delivery customisation
- Checkout UI extensions and Thank You page surfaces
- Billing API with plan tiers, trials and usage metering
- GDPR mandatory webhooks and uninstall cleanup
- App Store listing copy, screenshots and submission support
- Deployment on Railway, Fly or your own infrastructure
How it runs
Scope against the API first
Before pricing anything we check that Shopify's API actually exposes what your idea needs. Half of failed app projects die on a capability that was never available.
One surface at a time
Admin first, then the storefront or checkout surface, then billing. Each one deployed and clickable before the next begins.
Review readiness as a checklist
GDPR webhooks subscribed, not just coded. Uninstall tested. No secrets in the repo. The submission goes in once the list is clean.

Things people ask first
How long does a Shopify app take to build?
A private app for one merchant with a narrow scope is usually three to five weeks. A public App Store app with billing, multiple plans and a storefront surface runs eight to twelve weeks, plus review time. Shopify's review itself typically takes a few business days per round.
Can you get an app approved on the Shopify App Store?
We've been through submission and review feedback with our own app. The common rejection reasons — unsubscribed GDPR webhooks, session token handling, unclear billing disclosure, listing content that doesn't match the app — are all things we check before submitting rather than after being told.
Do you build public apps or custom apps?
Both. A custom app installed on one store skips App Store review entirely and is faster and cheaper. A public app is worth the extra work only if you intend to sell it to other merchants.
Who owns the code?
You do, on final payment. The repository is yours, hosted under your organisation if you'd prefer that from day one.
