Shopify App Services
Shopify App Development & Support
Beyond our own apps, we build custom Shopify apps, customize existing ones, upgrade them to the latest Shopify APIs, and fix the bugs that hold your store back. For Gemify apps or any other Shopify app.
What We Can Do for You
Tell us what your store needs. If it runs on Shopify and involves an app, we can help.
Custom App Development
Need a feature no app offers? We design and build Shopify apps around your workflow, from a private app for one store to a public app for the Shopify App Store.
- Custom apps built for your store only
- Public apps ready for Shopify App Store review
- Admin, checkout, and theme app extensions
- Integrations with ERPs, CRMs, and other services
App Customization
Want an app to do a little more, or work a little differently? We add features and change behavior in Gemify apps and in apps built by other developers.
- New features and settings for Gemify apps
- Changes to apps built by other developers or agencies
- Custom rules, reports, and automations
- Connections to the tools you already use
Upgrades & Migrations
Shopify releases a new API version every quarter and retires old ones. We keep your app current before a deprecation breaks it.
- Shopify API version upgrades
- REST to GraphQL Admin API migration
- Polaris and App Bridge updates
- Framework and dependency upgrades
Bug Fixes & Maintenance
App throwing errors, running slowly, or losing data between systems? We find the cause, fix it, and keep the app healthy.
- Diagnose and fix errors and crashes
- Webhook, sync, and data-consistency issues
- Performance and reliability improvements
- Ongoing maintenance and monitoring
