Case Study

Client Profile

Fashion & Apparel

Challenge

Fast-growing apparel brand on Shopify doing $3M ARR but site crashed every Black Friday. Last year's Black Friday outage lasted 6 hours and cost $180K in lost revenue. Checkout conversion was only 1.8% (industry average 3.5%). Managing inventory across Shopify, Amazon, and wholesale was causing constant overselling problems. Wanted to scale to $10M ARR but platform couldn't handle it.

Solution

E-commerce consultant implemented headless architecture with Next.js frontend and Shopify backend, added Cloudflare for caching and DDoS protection, rebuilt checkout flow with one-page checkout and Apple Pay/Google Pay integration, implemented real-time inventory sync across all channels using custom middleware, added product recommendation engine using Algolia, set up comprehensive performance monitoring, and load-tested system to handle 10x Black Friday traffic.

Results

Black Friday handled 3.2x previous year's traffic with zero downtime and 99.99% uptime. Checkout conversion improved from 1.8% to 3.2% (78% improvement), adding $640K annual revenue. Site load time dropped from 4.2s to 1.1s. Inventory sync reduced overselling incidents from 30+ per month to 2-3. Scaled to $8.5M ARR within 12 months. AOV increased 22% through better recommendations.

"Last Black Friday we lost $180K to site crashes. This year we handled 3x the traffic flawlessly and had our biggest day ever. The checkout optimization alone paid for the entire engagement."
