FAQs

frequently asked questions

Still curious? Ask us directly — we reply within 12 hours, and it’s an engineer who answers.

What's the difference between a public, private, and custom Shopify app?

Public apps are listed on the Shopify App Store and installable by any merchant. Custom apps are built for one store, installed directly through the Partner Dashboard. Private/embedded apps sit inside Shopify admin using App Bridge and Polaris for a native feel.

How long does it take to build a Shopify app?

A focused single-purpose app typically takes 4 to 6 weeks. Apps with billing, multi-store support, or deeper API integrations usually run 8 to 10 weeks depending on scope.

Do you handle Shopify App Store submission and review?

Yes. We prepare listing assets, handle the technical review checklist, respond to Shopify’s review team, and manage resubmissions until the app is approved and live.

What tech stack do you use to build Shopify apps?

Remix is our default framework per Shopify’s current recommendation, paired with React, Polaris for UI, App Bridge for embedding, and GraphQL for the Admin API. Node.js handles backend logic and webhooks.

Can you add billing and subscriptions to a Shopify app?

Yes. We implement Shopify’s Billing API for one-time charges, recurring subscriptions, and usage-based pricing, so your app can monetize from day one without a separate payment processor.

Can an app include custom checkout functionality?

Do you build apps for Shopify Plus specifically?

Yes, through Shopify Functions and Checkout UI Extensions we can ship discount logic, validation rules, custom banners, and post-purchase upsells as part of the same app.

What happens after the app is launched?

Every build includes a post-launch monitoring window covering crash reports, webhook failures, and Shopify API version deprecations, with an ongoing support plan available after that.

Can you migrate or rebuild an existing Shopify app?

Yes. We commonly rebuild apps still on the deprecated Shopify CLI 2 / Ruby stack, or apps failing new API version checks, onto the current Remix and GraphQL-based architecture.

How much does Shopify app development cost?

Single-purpose custom apps typically start at $8,000. Public apps with billing and multi-merchant support range from $18,000 to $45,000+ depending on integrations and complexity.
