Cut checkout abandonment in half on a $5M/mo store
Rebuilt the storefront and checkout for a high-volume merchant — faster pages, fewer drop-offs, and payment plumbing that just works.
The challenge
A high-volume merchant was losing customers right at checkout. Pages were slow, the flow leaked conversions, and the payment integrations were fragile across regions — a constant source of failed orders and support tickets.
What we did
We rebuilt the storefront and checkout with React and AJAX flows, then integrated and hardened 15+ payment gateways with proper OAuth, webhooks, and PCI handling. Redis caching and query tuning took the slow pages off the critical path.
The outcome
Checkout abandonment dropped roughly 50% and pages loaded about 45% faster. The store held 99.95% uptime through peak season while processing more than $5M in monthly transactions.
