Shopify app development

Shopify applications designed as maintained software products: not permanent prototypes.

We build public, custom and embedded Shopify apps with a clear product boundary, supported extension surfaces, observability and an operating path after launch.

Shugert develops Shopify apps using TypeScript, Remix or Next.js, App Bridge, Polaris, GraphQL Admin API, Functions, webhooks and theme-app extensions. App projects generally start at $6,000 USD; public-app MVPs often fall between $12,000 and $30,000 USD depending on billing, merchant surfaces, review requirements and operational scope.

  • Product boundary before build
  • Supported Shopify surfaces
  • Security, billing and operations included

Review the product boundary

When this fits

The capability needs its own lifecycle, permissions and owner.

An app is appropriate when the requirement has become software rather than theme configuration.

  1. 01

    You are launching a merchant product

    The business needs tenancy, billing, onboarding, support and App Store operations beyond a prototype.

  2. 02

    Internal operations need a dedicated tool

    Merchandising, finance or support workflows need a secure admin surface with their own permissions.

  3. 03

    Theme code is carrying platform behavior

    A snippet has grown into logic that needs independent deployment, upgrades and observability.

  4. 04

    Legacy scripts need supported replacements

    Discount, delivery, payment or cart behavior belongs in Functions or another supported extension point.

Product position

The release is the beginning of the application lifecycle.

Architecture, security, review, billing, monitoring and support need to exist before the first merchant depends on the app.

01

Product boundary before backlog

We define users, permissions, data, commercial model and Shopify surfaces before estimating screens.

02

Platform compliance is architecture

OAuth, GDPR webhooks, billing and supported extensions influence the design from day one.

03

Operations are part of the MVP

Logs, error handling, support access and deployment controls are not postponed to an undefined second phase.

What you receive

An app scope that covers product, platform and operations.

The package makes the application reviewable by product, engineering and security stakeholders.

01Product boundary

What belongs in the app?

Users, journeys, permissions and exclusions

02Platform architecture

Which Shopify surfaces are supported?

APIs, extensions, Functions and data flows

03Operational design

How is the app monitored and supported?

Logging, alerts, environments and access

04Staged product

Can representative merchant states be reviewed?

Dev-store flows, fixtures and QA

05Launch package

How does it reach production?

Submission or install plan, security and handoff

Coverage

A complete app lifecycle across Shopify and the hosting layer.

The final architecture depends on whether the app is public, custom or an internal product.

Product

  • Merchant onboarding
  • Billing and trials
  • Roles and permissions
  • Support surfaces

Shopify

  • App Bridge and Polaris
  • GraphQL Admin API
  • Functions and Flow
  • Theme-app extensions

Platform

  • Cloudflare or AWS
  • Queues and scheduled work
  • Databases and tenancy
  • Observability and alerts

Launch

  • OAuth and GDPR
  • App Store submission
  • Security review
  • Documentation and handoff

Delivery model

Product decisions precede implementation sprints.

A fixed scope remains useful only when product and platform assumptions are visible.

  1. 01

    Define

    Users, value, permissions, billing and the supported Shopify surface.

  2. 02

    Architect

    Data, tenancy, hosting, failure handling, security and environments.

  3. 03

    Build

    Implement reviewable flows in a development store with representative states.

  4. 04

    Launch

    Complete install or submission, monitoring, support and handoff.

Evidence standard

Review readiness is demonstrated by the package, not claimed as automatic approval.

We prepare apps for Shopify review and supported-platform requirements, but do not promise first-pass approval, a universal load time or Built for Shopify status before Shopify evaluates the product.

  • Supported extension surfaces documented
  • OAuth, permissions and GDPR flows reviewed
  • Billing and edge cases included in QA
  • Monitoring and support ownership visible

Limitation: Shopify controls App Store and Built for Shopify decisions. Review feedback and platform changes can alter the release path.

Explicit boundaries

Application ownership includes product decisions after launch.

The scope separates the initial build from ongoing support, merchant operations and roadmap work.

We handle

  • Architecture and implementation
  • Supported Shopify surfaces
  • Security and operational controls
  • Launch documentation

We coordinate

  • Product owner and support team
  • Shopify review feedback
  • External data and vendors
  • Legal and privacy review

We do not claim

  • Automatic first-pass approval
  • Built for Shopify status
  • A fixed latency for every merchant
  • Unlimited post-launch roadmap

Investment

Price follows product surface and operating responsibility.

App projects generally start at $6,000 USD. Public-app MVPs often range from $12,000 to $30,000 USD based on billing, tenancy, merchant surfaces, review and operational requirements.

Post-launch maintenance and roadmap capacity are scoped separately so the build price remains clear.

FAQ

Questions before building a Shopify app.

Do you build apps for the Shopify App Store?+

Yes. A public-app scope can include billing, OAuth, GDPR webhooks, App Bridge, Polaris, theme-app extensions, listing assets and the submission process. Shopify controls approval and Built for Shopify decisions, so review readiness is prepared but approval is not guaranteed.

Can you migrate a legacy Plus script to Shopify Functions?+

Yes, when the behavior maps to supported Function APIs. The scope documents current rules and edge cases, implements the supported replacement and validates parity in representative development-store states.

Which Shopify admin and extension patterns do you use?+

New builds use the current supported Shopify app surfaces appropriate to the product, which can include App Bridge, Polaris, Admin UI extensions, Functions, Flow and theme-app extensions. The architecture follows the required merchant journey rather than a fixed stack checklist.

Who owns the app and its revenue?+

The commercial and intellectual-property terms are written into the scope. Standard fixed-scope engagements are designed so the client owns the delivered application, data and direct platform relationships unless a different agreement is explicitly signed.

What happens after launch?+

The project can close with documentation and handoff, or continue through a separate maintenance and roadmap scope. API upgrades, platform changes, merchant support and new features require an explicit operating owner.

Shopify app development

Define the product boundary before estimating the interface.

Share the user, the job the app must perform, the Shopify surfaces involved and who will operate it. We will return a bounded product and architecture scope.
