Shopify App Development
We design and build custom Shopify apps end to end, from idea to a published App Store listing. We use the same modern stack behind our own published apps, Hide Out of Stock and Sortello, so your app is fast, native to the admin, and ready for review.
Custom Shopify apps from a team that ships its own
We design and build Shopify apps end to end: embedded admin apps, storefront features through theme app extensions, and private apps built for a single store. We use the same stack behind our own published apps, Sortello and Hide Out of Stock, so your app is fast, native to the Shopify admin, and ready for App Store review.
Private apps solve problems that no App Store app covers well, such as syncing inventory with a warehouse, sending orders to a shipping or accounting system, or connecting customer data to your email platform. Public apps go further, with billing, onboarding, and App Store submission.
We handle the full lifecycle: scoping, design, development with the GraphQL Admin API and webhooks, GDPR compliance, hosting, monitoring, and ongoing maintenance after launch.
App and integration work we do
Custom Shopify app development cost
A focused private app for one store is the lowest-cost option. Public apps cost more because they need billing, onboarding, and App Store review. Our guide to custom Shopify app cost explains the main cost drivers.
Connecting Shopify to payment and shipping services
We connect Shopify with payment and shipping services used in Europe and North America, such as Klarna and Afterpay for buy now, pay later, and carriers such as DHL, UPS, and Canada Post, using their official apps where they exist and custom integrations where they do not.
Shopify middleware and system integrations
When Shopify needs to talk to an ERP, warehouse, or accounting system, we build middleware that syncs products, stock, and orders reliably, with retries and logging so nothing is lost.
Build or buy: custom app vs App Store app
We tell you honestly when an existing app is the better choice, and recommend a custom build only when it saves money, replaces several apps, or does something no app can. Read our build-or-buy guide.
