Shopify app development cost is the estimated budget to design, build, test, and ship a Shopify app — private, public, or a theme app extension — including any integrations, admin UI, and billing.
What is the Shopify app development cost calculator?
This free tool estimates the cost of building a Shopify app. App pricing varies widely because a small theme extension and a public App Store app with billing and integrations are very different projects. Describe what your app does and get an instant range so you can plan before briefing a developer.
How this calculator works
The estimate combines your app type (private, public, or theme extension), its core function, the external systems it connects to, whether it needs an embedded admin built with Polaris, and its billing model. Public apps add App Store review, billing API, and GDPR webhook work; integrations and AI features add the most. A confidence band produces the low and high figures.
How to read your result
The cost range is your indicative one-time development budget. The timeline reflects build plus testing — and App Store review for public apps. The complexity score rises with integrations and AI, and the suggested engagement recommends hourly, project, or a dedicated app team.
When should you contact an app partner?
Integration behaviour, rate limits, and App Store requirements are where app scope grows, so an early review helps. The certified Shopify team behind this tool builds private and public apps. Talk to our app developers for an accurate plan.
Shopify app development cost by app type
Anyone searching "how much does it cost to build a Shopify app" quickly learns the range is wide. A simple theme app extension or private utility often costs $2,000–$6,000. A storefront-facing or data-sync app with one or two integrations usually runs $6,000–$15,000, while a public Shopify App Store app with billing, an embedded admin, and multiple integrations — or AI features — commonly exceeds $15,000–$30,000+. The Shopify app development cost depends on what the app does, not just its size.
Public apps carry extra cost that private apps skip: App Store review, the Billing API, and mandatory GDPR webhooks. Integrations and AI are the steepest drivers, and an embedded admin built with Polaris adds front-end work on top of the core logic.
Keeping Shopify app development cost in check
Control your Shopify app development cost by validating the core use case first and shipping a focused first version. Lean on Shopify's APIs and proven libraries instead of rebuilding common functionality, and stage advanced integrations or billing tiers for later releases. Budget for ongoing maintenance too — Shopify updates its platform regularly, so a maintainable app is cheaper over its lifetime than a quick build that needs constant rework.

Estimated Cost = App Type + Function + Integrations + Admin UI + BillingFactors
App type
Theme extensions and private apps are simpler than public App Store apps with review and billing.
Core function
A utility is far lighter than checkout extensibility, data sync, or AI-driven features.
Integrations
Each external API, ERP/CRM, payment, or AI connection adds development and error handling.
Admin interface
A full embedded admin built with Polaris adds UI work beyond a simple settings screen.
Billing model
Recurring or usage-based billing requires the Billing API and edge-case handling.
App Store readiness
Public apps add review, GDPR webhooks, and listing work that private apps skip.
- App cost depends on type, function, integrations, admin UI, and billing.
- Public App Store apps cost more than private apps due to review and billing.
- Integrations and AI features are the biggest cost drivers.
- An embedded Polaris admin adds meaningful UI work.
- Plan support for API changes and Shopify platform updates.

Frequently asked questions
How much does it cost to build a Shopify app?
A simple utility or theme app extension can start in the low thousands, while public App Store apps with integrations, embedded admin, billing, or AI run into the tens of thousands. The drivers are app type, function, integrations, admin UI, and billing. This calculator gives an instant range.
What is the difference between a private and public Shopify app?
A private (custom) app is built for one store and skips App Store review. A public app is listed on the Shopify App Store and must pass review, handle billing via the Billing API, and implement GDPR webhooks — all of which add cost. The calculator reflects this in the estimate.
Do Shopify apps need ongoing maintenance?
Yes. Shopify updates its APIs and platform regularly, so apps need maintenance to stay compatible, plus monitoring and support. This is shown as a separate recurring monthly cost.
How long does it take to build a Shopify app?
A simple app can be built in a few weeks; apps with multiple integrations, embedded admin, billing, or AI take longer, and public apps add App Store review time on top of development.
Can a Shopify app use AI?
Yes. Apps can call AI or LLM services for features like recommendations, content generation, or support. AI features add integration and prompt-handling work, which the calculator accounts for as a connection type.
Is the app estimate a fixed quote?
No. It is an indicative planning range based on typical app projects. A precise quote follows a discovery session covering function, integrations, and platform requirements.
