How do you handle Shopify API rate limits in custom apps?

Rate limit management is built into every app we develop. We implement request queuing using Bull or BullMQ, respect Shopify's leaky bucket and cost-based throttling models for GraphQL, and use exponential backoff strategies for retries. For high-volume apps we architect background job processors and use bulk operation APIs like bulkOperationRunQuery so your app scales without hitting Shopify's limits. We also set up monitoring alerts so throttling events are caught in production before they affect merchants.

Can you build a Shopify app that works across multiple stores or markets?

Yes. Multi-store and multi-market apps are something we design for from the ground up. For merchants managing multiple Shopify stores, we build centralized admin dashboards that aggregate data and push configurations across all connected stores via the Admin API. For Shopify Markets, we handle currency, language, and regional pricing logic within the app layer. Our multi-tenant architecture ensures complete data isolation between each merchant installation as you scale to hundreds or thousands of installs.

What security practices do you follow when building Shopify apps?

Security is a first-class requirement in every project. All access tokens are encrypted at rest using AES-256, webhook payloads are verified using HMAC signatures before processing, and we implement strict OAuth 2.0 flows with session token validation via Shopify App Bridge. We apply the principle of least privilege when requesting API scopes, never store unnecessary customer PII, and conduct dependency audits using Snyk or npm audit before every deployment. For sensitive apps we can include a dedicated security review and penetration testing phase.

How do you price projects — fixed cost or hourly?

We offer both models. For well-defined projects with clear requirements, we use a fixed-price contract with a milestone-based payment schedule and no surprise invoices — ideal for private apps, integrations, and scoped feature builds. For ongoing or exploratory projects where requirements evolve, we work on a time-and-materials retainer with weekly or monthly billing. Either way, we never start development without a written scope of work signed by both sides.

FREQUENTLY ASKED QUESTIONS

Answers to what most clients ask before starting their Shopify app project.

1. When should a business build a custom Shopify app instead of using a public app?

You should consider a custom Shopify app when existing apps cannot support your specific workflows, integrations, or business logic. Many growing stores rely on multiple third-party apps that create performance issues, subscription costs, and limited customization. A custom app is built specifically for your store and can integrate directly with your internal systems, automate workflows, and implement advanced features without the limitations of public apps.

2. Can a custom Shopify app integrate with third-party systems like ERP, CRM, or shipping platforms?

Yes. One of the biggest advantages of custom Shopify apps is the ability to integrate directly with external systems such as ERP platforms, CRMs, inventory systems, fulfillment tools, or accounting software. Custom apps can use Shopify APIs to securely sync data like orders, products, inventory, and customers, enabling automated workflows and reducing manual operations across your business systems.

3. How long does a custom Shopify app take to build?

A focused private app takes 3–6 weeks. A full-featured custom app with admin UI and integrations typically takes 8–16 weeks. Public App Store apps with multi-tenancy can take 3–5 months depending on complexity.

4. Can you upgrade or fix my existing Shopify app?

Yes. We regularly take over existing apps for maintenance, API version upgrades, performance improvements, or feature additions. We start with a code audit to understand what was built before.

5. What's the difference between a private and public Shopify app?

Private apps are exclusive to one store and don’t need Shopify App Store review. Public apps are listed on the App Store, available to all merchants, and require Shopify’s review and approval process.

6. Do you sign NDAs and hand over the source code?

Yes, absolutely. We sign NDAs before any project discussions and all source code, documentation, and IP transfers fully to you upon project completion and final payment.

7. Do you work with Shopify Plus merchants?

Yes, a significant portion of our clients are on Shopify Plus. We build custom checkouts, Shopify Scripts replacements (Checkout Extensions), B2B apps, multi-store management tools, and Flows integrations.

8. What post-launch support do you provide?

All projects include a post-launch support window (30–90 days depending on plan) covering bug fixes and minor adjustments. After that, we offer monthly retainer packages for ongoing maintenance, API version updates, and new features.

9. Are Shopify custom apps secure for handling store and customer data?

Yes, when developed properly. Custom Shopify apps operate with defined API permissions that control what data the app can access or modify. This allows developers to restrict access to only the required resources, improving security and reducing unnecessary data exposure. Proper authentication, secure API usage, and best development practices ensure that customer and store data remain protected.

10. Can a Shopify custom app scale as my business grows?

Yes. Custom apps are designed to evolve with your business. Unlike public apps that follow a fixed feature roadmap, custom apps can be expanded over time with new features, integrations, or automation workflows. As your store scales—whether through higher order volume, new markets, or additional systems—your custom app can be enhanced to support those changes without requiring a complete replacement.
