Shopify Apps & Custom App Development

Build, Integrate & Extend Your Shopify Store With Apps

Connect Shopify with the tools your business already uses—or build a custom app when your business needs functionality that off-the-shelf solutions cannot provide.

Two Ways We Extend Shopify

Use an Existing App—or Build Exactly What Your Business Needs

Not every ecommerce requirement needs custom development. We first look at what already exists, then choose the practical path for your workflow.

  • ✓CRM, ERP and business-system connections

When Existing Apps Aren't Enough

Build a Shopify App Around the Way Your Business Actually Works

Shopify has a large app ecosystem, but some business processes are too specific for a standard app. A custom app can bring your internal workflow, data and Shopify experience together in one purpose-built solution.

  • ✓Design functionality around your exact business requirements.
  • ✓Connect Shopify with proprietary or internal systems.
  • ✓Automate repetitive operational processes.
  • ✓Create merchant-facing tools inside Shopify Admin.
  • ✓Extend Shopify where standard configuration is not enough.

Our Development Process

From Business Requirement to Working Shopify App

We start with the business workflow, then map the technology around it.

1

Discover

Understand the requirement, users, systems and business rules.

2

Plan

Define architecture, data flow, permissions and Shopify surfaces.

3

Design

Plan the merchant, customer or operational experience.

4

Develop

Build the app, APIs, extensions and integrations.

5

Test

Validate workflows, edge cases, data and failure scenarios.

6

Launch

Deploy, configure, document and support the solution.

Built for Reliability

We Think Beyond the Happy Path

A Shopify integration or custom app needs to behave predictably when data is incomplete, events arrive more than once, an API request fails or a connected system is temporarily unavailable.

  • ✓Authentication and least-privilege permissions
  • ✓Data validation and transformation
  • ✓Duplicate-event and retry considerations
  • ✓API limits and failure handling
  • ✓Functional, integration and regression testing
Infylo Approach

Technology + QA + Ecommerce Thinking

We look at the integration from both the technical and ecommerce perspective: what data moves, what the merchant experiences, what the customer experiences, and what happens when something goes wrong.

Frequently Asked Questions

Shopify Apps & Custom App Questions

What is the difference between a Shopify app integration and a custom Shopify app?

An integration connects Shopify with an existing application or business system. A custom app is purpose-built around a specific business requirement, workflow or system.

Can you integrate Shopify with our existing ERP or CRM?

Yes. We can review the systems, APIs, data requirements and workflow, then determine the appropriate integration approach.

Can you build a custom Shopify app for our internal team?

Yes. Custom apps can support merchant and operational workflows such as product management, order operations, reporting and automation.

Can you work with an existing Shopify app or integration?

Yes. We can review an existing connection, troubleshoot issues, improve workflows or extend the solution where the platform allows.

Can you build Shopify Admin extensions?

Yes. Shopify provides extension points for merchant workflows inside Admin, including contextual actions and blocks on supported resource pages.

Can you test the app before production?

Yes. We recommend testing authentication, permissions, normal workflows, data mapping, duplicate events, failures, retries and relevant Shopify surfaces before production release.
