+42% online sales
Custom checkout flows, headless CMS, and a performance-first storefront built to scale with seasonal demand.
RetailCo needed a modern storefront that could handle peak traffic, support complex promotions, and give their merchandising team full control without developer bottlenecks.
Their legacy platform slowed checkout, broke under holiday traffic, and required engineering support for every content change — hurting conversion and time-to-market.
We rebuilt the experience on a headless architecture with a custom checkout, real-time inventory sync, and a CMS-driven product catalog. Performance budgets and edge caching keep pages fast even during sales spikes.

From kickoff to launch — the step-by-step process we followed with RetailCo to reach measurable results.
We mapped existing checkout friction, catalog workflows, and peak-traffic bottlenecks with RetailCo’s merchandising and ops teams.
Headless stack, CMS structure, and checkout wireframes were defined with performance budgets and conversion goals baked in.
Storefront, payments, inventory sync, and analytics were developed in sprints with staging reviews after each milestone.
Load testing, go-live support, and post-launch CRO tuning helped the store perform through the first major sales season.

“Our new store handled Black Friday traffic without a hitch. Checkout is faster, the team updates content on their own, and online sales are up significantly since launch.”

Answers about scope, timeline, and outcomes for the RetailCo project.
How long did the RetailCo e-commerce rebuild take?
Discovery through launch took roughly 14 weeks, including checkout redesign, CMS setup, payment integration, and load testing ahead of peak season.
Why did you choose a headless architecture?
Headless gave RetailCo a fast storefront frontend while letting merchandising manage catalog and content in a CMS without developer involvement for every update.
How did you prepare the store for peak traffic?
We set performance budgets, used edge caching, ran load tests simulating holiday traffic, and monitored Core Web Vitals before and after launch.
Can this approach work with existing inventory systems?
Yes. We integrated real-time inventory sync with RetailCo’s existing backend so stock levels stay accurate across channels during high-volume sales.
