Shopify for Enterprise Migration
Replatforming Shop LC to Shopify Enterprise in 3 Months with Zero Downtime
About Project
Shop LC processes 5,000+ daily orders peaking at 11,000 orders and $1M+ daily revenue. To eliminate legacy limits, we migrated 5 years of user profiles, 1.1M SKUs, 2,500 categories, 1,000 CMS pages, active carts, wishlists, and store credits without data loss. Driven by 32+ custom Shopify apps, Shopify Functions, Subscription APIs, and Checkout UI Extensions, the cloud architecture achieves <250ms Time to First Byte (TTFB), 1.4s Largest Contentful Paint (LCP), and near-real-time sync across 27+ enterprise systems like AMS and Pimcore PIM.

Business Goal
The primary objective was migrating three non-standard revenue channels: Live TV Shopping, $1 Rising Auctions, and an in-house installment engine, onto a platform natively supporting none of them, before SFCC contract expiration. Shop LC demanded 99.99%+ uptime, GTmetrix Grade A performance, PCI compliance, and WCAG accessibility during flash-sale spikes. We built an agile Shopify Enterprise architecture that handles complex commercial logic, bypasses Shopify’s native 3-option limit to support up to 7 custom variant dimensions, and drives long-term growth.
Project Highlights
- 3-Month SFCC to Shopify Enterprise Replatforming
- Zero Data Loss Migration of 1.1M-SKU catalogue and 2M+ users
- In-House Installment Payment Engine Development
- Recalculation of Live TV Falling-Price and $1 Rising Auction Engines
- 27+ Enterprise Systems Synchronized in Real-Time

Key Challenges
Immovable Contract Expiration Window
SFCC contract was expiring in 4 months, demanding a full enterprise migration inside half of the client’s 6-month RFP allowance.
Scoping Complex Tri-Model Commerce
Unifying live TV broadcast, dynamic rising auctions, and retail into one functional roadmap required clarifying overlapping specs.
Native Checkout Limits
Shopify’s native checkout lacked support for Shop LC’s high-converting, proprietary in-house installment payment model.
Dynamic Price Recalculation Demands
Standard eCommerce checkouts assume fixed item prices, conflicting with live broadcast falling-price shows settled post-broadcast.
Our Solutions
Seamless Enterprise Migration
To execute a risk-free transition, we developed automated pipelines to translate legacy SFCC data into Shopify schemas, migrating 1.1M SKUs, 200k active products, 2M+ profiles, active carts, and store credits. Recognizing that lost rankings cost more than the project, we executed a rigorous SEO protection program: mapping all URLs, preserving metadata, enforcing canonical parity, testing staging/production 301 redirects, replicating robots.txt, and migrating GA4/GTM events. This ensured zero data loss and retained full organic search equity.
Accelerated Phased Delivery
After a 10-week discovery phase aligned complex requirements, we deployed an AI-assisted pipeline (Figma-to-Liquid generators and QA agents) to hit the aggressive 3-month deadline. We then executed a progressive 1% to 2% to 100% traffic cutover with the legacy platform running in parallel. For a retailer handling 5,000–11,000 daily orders, this turned a high-stakes gamble into a controlled, zero-downtime launch. Furthermore, thorough collection-page optimization guaranteed a client-mandated GTmetrix Grade A performance across thousands of SKUs.
Custom Payment Architecture
To overcome Shopify checkout limitations and bypass third-party BNPL fees, we developed a custom in-house installment engine. Powered by Shopify Subscription APIs and Checkout UI Extensions, the solution validates customer credit standing (New, Good Standing, Delinquent) and revolving balances ($500 default limits) against AMS in real time. It enforces credit-eligibility blocks, schedules independent recurring payments, and routes store credits smoothly, keeping the checkout secure, PCI-compliant, and highly reliable.
Dynamic Commerce Engines
To solve pricing that isn’t fixed at order time, we inverted standard checkout logic. For the Live TV falling-price flow, our engine authorizes payments at TSP+25%, dynamically recalculates mixed carts post-show, reconciles reserved inventory, and captures the final closing price. We also built a real-time $1 Rising Auction platform processing 100k products and 1M daily bids, alongside a custom discount engine driving multi-tier promotions and automated clearance offloading across 27+ real-time enterprise integrations.
Our Approach
Our methodology focused on executing an agile transformation that harmonized complex broadcast retail features with scalable enterprise architecture.
