Custom Shopify Storefront
Client: Greenleaf Naturals
Greenleaf Naturals, a DTC wellness brand, was losing mobile shoppers to a sluggish WooCommerce store that hadn't kept pace with their growth. IO Datalabs rebuilt their storefront on Shopify Plus with a headless Hydrogen frontend — cutting page loads from 2.8s to 0.9s and driving a 65% lift in mobile conversions.
The Challenge
Greenleaf Naturals had outgrown their WooCommerce setup. The theme was heavily customized with conflicting plugins, resulting in 2.8-second average page loads on mobile — well above the 1.5s threshold where conversion rates drop sharply.
Mobile traffic accounted for 72% of their visitors but only 35% of revenue, a clear signal that the mobile shopping experience was broken. Cart abandonment on mobile was 78%, nearly double the desktop rate.
Their subscription program — a key revenue driver for consumable wellness products — was managed through a third-party WooCommerce plugin that frequently broke during WordPress updates and offered no flexibility for custom subscription flows.
Our Approach
We migrated Greenleaf to Shopify Plus with a headless architecture, prioritizing mobile performance and subscription flexibility from day one.
Audit & Migration Planning
Audited the existing WooCommerce store — cataloged 1,200+ products, subscription configurations, and customer data. Mapped the migration path to Shopify Plus with zero downtime requirements.
Hydrogen Storefront Build
Built the headless storefront using Shopify Hydrogen and Remix, with server-side rendering for instant page loads. Implemented mobile-first design with Tailwind CSS and optimized image delivery via Shopify CDN.
Subscription & Checkout Optimization
Built custom subscription management using Shopify Functions, allowing flexible delivery schedules and easy plan modifications. Optimized the checkout flow with one-tap purchase options and Klaviyo-powered abandoned cart recovery.
Migration & Launch
Migrated product catalog, customer accounts, and subscription data. Ran parallel operations for 1 week, then cut over with DNS redirect. Zero orders lost during migration.
The Solution
The new Hydrogen-powered storefront delivers sub-second page loads on mobile through server-side rendering and edge caching. Product pages feature dynamic variant selection, real-time inventory, and one-tap subscription enrollment — all without full page reloads.
The subscription engine built on Shopify Functions gives customers full control over delivery frequency, product swaps, and pause/resume — reducing subscription churn by letting customers self-serve instead of canceling. Klaviyo integration powers personalized email flows triggered by browsing behavior and purchase history.
