How Much Does It Cost To Build A Public Shopify App For The App Store, And What Do Teams Underestimate?

5 MIN READ

A public app costs more than the first build. Third-party 2026 estimates run $10,000 to $25,000 for a small utility and $25,000 to $60,000 for a feature-rich app, plus $20,000 to $50,000 in first-year operations for an MVP. Teams usually underestimate App Store review, privacy webhooks, scaling across many shops and support. Start with one core job, Shopify billing and a clean review.

A public app costs far more than the first build. Third-party 2026 estimates put a small utility at $10,000 to $25,000, a feature-rich app at $25,000 to $60,000 and a platform-level app above $60,000, with first-year operations adding $20,000 to $50,000 for a typical MVP. The usual underestimates are App Store review, privacy webhooks, scaling across many shops and support.

Start smaller than you think. A realistic first version solves one job well, bills through Shopify and passes review. Our guide to the cost of building a Shopify app covers the budget in more detail.

Where the money goes

Core build is only one of four cost blocks.

1
Core build

What: the main feature set, the embedded admin interface and the data model.

Range: $10,000 to $25,000 for a small utility, $25,000 to $60,000 for a feature-rich app.

2
App Store readiness

What: review preparation, listing assets, test instructions and review fixes.

Watch for: two or three resubmission cycles are common.

3
Billing and onboarding

What: Shopify billing integration, plan logic, trials and a first-run experience.

Watch for: billing misuse is a common rejection reason.

4
Operations and support

What: hosting, monitoring, support, API version updates and fixes.

Range: first-year operations of $20,000 to $50,000 for an MVP, per one 2026 estimate.

Public app type Build cost Typical timeline
Small utility $10,000 to $25,000 2 to 3 months
Feature-rich SaaS app $25,000 to $60,000 3 to 6 months
Large platform-level app $60,000 or more 6 months or more

Figures are third-party 2026 estimates and vary by scope and team.

The App Store requirements checklist

Build these in from day one, not after the first rejection.

Requirements to plan for
  • Subscribe to the three privacy webhooks, verify them and respond with a 200 status.
  • Complete data requests and deletions within 30 days.
  • Bill through Shopify App Pricing or the Billing API.
  • Use theme app extensions instead of editing theme files or injecting script tags.
  • Show a visible support contact in the app and on the listing.
  • Provide test instructions and test accounts for any outside services.
Built for Shopify bar, if you want the badge
  • At least 50 net installs from active shops on paid plans and at least 5 reviews.
  • Admin LCP of 2.5 seconds or less, CLS of 0.1 or less and INP of 200 ms or less.
  • No more than a 10-point drop in storefront Lighthouse score.
  • A p95 response time of 500 ms or less for apps that handle checkout requests.

Built for Shopify criteria are reported by third-party sources, so verify them in Shopify’s partner documentation.

What teams always underestimate

These four items cause most budget and schedule overruns.

The review process

Review feedback arrives per requirement and resubmission cycles take time. Plan at least a week per cycle.

Privacy webhooks

Every app must handle them, even with no personal data, and the 30-day completion rule is a real operational duty.

Multi-shop scaling

Each app and shop pair gets its own API quota, so you must queue and throttle per shop as installs grow.

Support and upkeep

Merchants expect fast answers, and Shopify releases a new API version every quarter.

Public app versus custom app

The extra cost of going public is real, so choose it on purpose.

Go public if
You want to sell to many merchants
✓
You want App Store distribution and billing.
✓
You can fund support and operations.
✓
The product works for unrelated merchants.
✓
You can pass review and meet the privacy rules.
Stay custom if
You serve one merchant or a few
✕
The app is for your own stores or one client.
✕
You do not need an App Store listing.
✕
You want lower review and support overhead.
✕
The logic is specific to one business.

Rule of thumb: if you cannot fund support and operations, a smaller custom app is the safer first step.

A realistic first version

Scope for review and revenue, not for completeness.

What to include in version one
  • One core job that merchants already pay for.
  • An embedded admin interface built with Polaris and App Bridge.
  • Shopify billing with a simple plan.
  • Privacy webhooks, install and uninstall handling.
  • A theme app extension only if the app needs a storefront feature.

Frequently Asked Questions

How much does it cost to build a public Shopify app?

Third-party 2026 estimates run $10,000 to $25,000 for a small utility, $25,000 to $60,000 for a feature-rich app, and $60,000 or more for a platform-level app, with first-year operations on top.

How long does App Store review take?

Shopify publishes no fixed turnaround. Plan for at least a week, and expect two or three resubmission cycles before approval.

Do I have to use Shopify billing?

Yes. Paid apps must bill through Shopify, using Shopify App Pricing or the Billing API. Collecting app fees with your own card form or processor inside the app is not allowed.

What are the mandatory privacy webhooks?

customers/data_request, customers/redact and shop/redact. Every App Store app must subscribe to all three, even if it stores no personal data, and complete requests within 30 days.

What does Shopify take from app revenue?

Reported terms are a one-time $19 registration fee, 0 percent on the first $1M of lifetime revenue earned since January 1, 2025, then 15 percent, plus a 2.9 percent processing fee. Confirm current terms in Shopify’s partner documentation. Our custom Shopify app development team can scope your build.
