Project Overview

Developing a custom subscription management app for a high-growth e-commerce brand.

📱

The Client

MobileMustHave.com — a leading mobile internet solutions and accessories retailer generating six-figure monthly revenue, requiring a robust subscription system to drive predictable recurring revenue.

🎯

The Mission

Build a custom Shopify subscription app that handles complex subscription logic, integrates seamlessly with Shopify's ecosystem, and provides a polished admin experience using Shopify Polaris.

🚀

The Approach

Full-stack development using Next.js for the frontend, Koa for the backend, Apollo Client for GraphQL operations, and Shopify's Polaris design system for a native admin experience.

The Challenge

Off-the-shelf subscription apps couldn't meet the brand's unique requirements.

⚠

Business Challenges

  • Generic subscription apps lacked the flexibility for custom billing cycles and product bundles
  • No native integration with their existing inventory and fulfillment workflows
  • Limited control over subscription pause, skip, and cancellation flows
  • Poor admin UX in existing solutions made management cumbersome
  • High transaction fees from third-party subscription platforms eating into margins
✓

Custom Solution

  • Tailored subscription logic with flexible billing intervals and custom bundle configurations
  • Direct integration with Shopify's Orders, Products, and Customers APIs
  • Full control over customer self-service portal for managing subscriptions
  • Native Polaris UI providing familiar, intuitive admin experience
  • Zero third-party fees — app owned entirely by the merchant
