Building a Shopify app is different from customizing a theme or installing an existing app.
A custom app may need to sync inventory with an ERP, automate order workflows, support checkout logic, process webhooks, connect external platforms, or serve hundreds of merchants through the Shopify App Store. That means the development partner needs more than general Shopify experience.
This list focuses on companies with verifiable experience in custom apps, integrations, public Shopify apps, or complex Shopify engineering.
How We Selected These Shopify App Development Companies
This list is not based only on marketing claims or directory rankings.
We looked for signals such as:
- Current Shopify Partner presence
- Custom apps and integrations as a documented capability
- Published Shopify apps where available
- Merchant-specific app development
- Systems integration experience
- Shopify Partner tier
- Evidence of ongoing Shopify engineering
Shopify currently categorizes service partners into tiers such as Select, Plus, Premier, and Platinum. Partner status is useful context, but it should not be treated as proof that a company has experience with every type of Shopify app project.
Editorial disclosure: Lucent Innovation is included because this article is published by Lucent. It was evaluated using the same criteria applied to the other companies.

Which Type of Shopify App Development Partner Do You Need?
Before comparing proposals, define what you're actually building.
| Project type | Experience to prioritize |
|---|---|
| App for one merchant | Custom distribution, Shopify APIs, merchant workflows |
| SaaS app for many merchants | Public app development, OAuth, billing, App Store review |
| ERP/WMS/3PL integration | Webhooks, APIs, queues, retries, data reconciliation |
| Checkout or business logic | Shopify Functions and supported checkout extensions |
| Admin workflow | Shopify Admin extensions and embedded app architecture |
| POS workflow | Shopify POS extensions and retail-system experience |
| Customer account feature | Customer Account API and extension experience |
This distinction matters because the development requirements vary considerably.
A custom application used by one merchant does not have the same distribution, authentication, onboarding, billing, or App Store requirements as a public SaaS app.
Shopify currently separates application distribution into custom distribution and public distribution. Public apps can serve multiple unrelated merchants and must meet Shopify's applicable App Store requirements.
What to Check Before Hiring a Shopify App Development Company
1. Current Shopify API knowledge
The development company should understand Shopify's current architecture rather than rely on older implementation patterns.
Shopify marked the REST Admin API as legacy in October 2024, and new public apps have been required to use the GraphQL Admin API since April 2025.
Depending on the project, the development team may also need experience with:
- GraphQL Admin API
- Storefront API
- Customer Account API
- Shopify Functions
- Webhooks
- Admin UI extensions
- Checkout UI extensions
- Theme app extensions
- App Bridge
A technical proposal should explain which parts of this architecture are actually relevant rather than mentioning every Shopify technology available.
2. Experience with your specific type of app
A Shopify Partner badge tells you that a company works within the Shopify ecosystem. It doesn't tell you whether that company has solved your particular problem before.
For a public app, look for evidence of public apps that have been launched and maintained.
For an ERP integration, ask about synchronization, retry logic, rate limits, queues, failure recovery, reconciliation, and monitoring.
For a product configurator, look for experience handling product logic, variants, SKUs, pricing, inventory, and front-end state.
Comparable engineering experience is usually more valuable than a long list of unrelated Shopify projects.
3. Authentication and data security
App architecture should define how sensitive merchant and customer data is accessed and protected.
Ask how the team handles:
- OAuth
- Access tokens
- Token refresh
- API scopes
- Secret storage
- Webhook validation
- Customer data
- Merchant data
- Uninstall workflows
- Data cleanup
This is increasingly important as Shopify updates its authentication requirements.
For example, public apps created from April 1, 2026 that access the Admin API must use expiring offline access tokens.
4. App ownership
Clarify ownership before development starts.
Your agreement should define who controls:
- Source code
- Git repository
- Shopify app configuration
- Databases
- Hosting
- Cloud infrastructure
- Domains
- CI/CD pipelines
- Monitoring tools
- Third-party services
This becomes important if you eventually move development to another team.
A clean handover should not require rebuilding the application.
5. Failure handling
Integration-heavy Shopify applications should be designed for failures, not only successful requests.
An ERP can become unavailable. A webhook may be delivered more than once. A third-party API may rate-limit requests. Inventory updates can arrive out of order.
The development team should be able to explain how the system handles:
- Retries
- Duplicate events
- Idempotency
- Queue failures
- Partial synchronization
- Reconciliation
- Logging
- Alerts
These issues often matter more in production than the initial API connection itself.
6. Shopify platform changes
Shopify apps require maintenance after launch.
Shopify releases API versions regularly and continues to update its application platform, extensions, authentication requirements, and App Store standards.
The contract should define who monitors:
- API version changes
- Deprecated APIs
- Security updates
- Webhook changes
- Authentication requirements
- Extension changes
- App Store requirements
- Production errors
This is particularly important for public apps that depend on remaining compatible across many merchant stores.
Mistakes to Avoid When Hiring a Shopify App Development Company
Choosing the right development partner is not only about finding the company with the strongest portfolio. Some mistakes can create technical debt, unexpected maintenance costs, or ownership problems long after the app goes live.
Choosing a Shopify agency without verifying app experience
Store development and app development require different skills.
A team may be excellent at themes, Liquid, storefront UX, or Shopify migrations but have limited experience with backend applications, APIs, authentication, webhooks, queues, or external systems.
Look for evidence that matches the application you actually plan to build.
Starting development before deciding how the app will be distributed
A public Shopify app and a merchant-specific custom app should not be treated as the same project.
Distribution affects authentication, onboarding, permissions, billing, App Store review, multi-tenant architecture, and long-term support.
Making that decision after development has started can lead to unnecessary rework.
Treating an integration as a simple API connection
Connecting Shopify to an ERP, CRM, WMS, or 3PL involves more than sending data between two APIs.
Production integrations need to account for failed requests, duplicate events, API limits, delayed updates, unavailable systems, and conflicting data.
Ask how the team will handle retries, queues, idempotency, reconciliation, and monitoring before approving the architecture.
Leaving code and infrastructure ownership unclear
A business should not discover after launch that its development vendor controls the only repository or cloud account.
Clarify ownership of the source code, Shopify app, hosting, database, deployment pipeline, third-party accounts, and documentation in the contract.
This makes future maintenance and vendor changes much easier.
Focusing only on the initial development cost
The lowest development quote is not always the lowest long-term cost.
Shopify apps may require infrastructure, monitoring, third-party services, security updates, API upgrades, bug fixes, and ongoing platform maintenance.
Compare the total operating model, not only the cost to reach the first release.
Ignoring future Shopify platform changes
An app that works at launch may need updates as Shopify changes APIs, authentication methods, extensions, and platform requirements.
Ask who will monitor these changes and how upgrades will be handled after the original development engagement ends.
Skipping technical documentation and handover
The application should not depend entirely on knowledge held by the original developers.
Architecture notes, environment setup, deployment instructions, API dependencies, monitoring processes, and repository access should be part of the final delivery.
Good documentation reduces the risk and cost of maintaining the app later.
Questions to Ask Before Signing the Contract
A few focused questions can tell you more than a long capability presentation.
Have you built this type of Shopify app before?
Ask for evidence that resembles your architecture rather than another Shopify storefront.
Should this be a custom-distribution app or a public app?
The answer should depend on your intended users and business model.
Which Shopify APIs, Functions, or extensions would you use?
The company should be able to explain why each technology belongs in the architecture.
What happens if Shopify or another connected system is temporarily unavailable?
Listen for discussion of retries, queues, reconciliation, monitoring, and failure recovery.
Who owns the application and infrastructure?
Repository, hosting, Shopify app ownership, cloud accounts, and documentation should be clear.
Who maintains the app when Shopify changes its APIs?
Platform maintenance should be part of the long-term plan, not an afterthought.
Final Considerations
There isn't one Shopify app development company that fits every project.
A company experienced in public Shopify apps may be a strong fit for a SaaS product. A team with ERP and middleware experience may be more appropriate for inventory or fulfillment integration. Another company may be better suited to custom product logic or internal merchant workflows.
Start with four questions:
What must the app do?
Who will use it?
Which systems must it connect to?
Who will maintain it after launch?
Then evaluate development companies against those requirements.
That gives you a much stronger basis for selection than agency size, hourly rate, review count, or Shopify Partner tier alone.
