Checkout Deep Dive

The Challenge

A legacy monolithic storefront led to severe performance bottlenecks during flash sales, resulting in cart abandonments and lost revenue.

The client required localized payment gateways, instant inventory validation, and a 1-click checkout experience across 12 international markets.

Core Objectives

  • SUB-SECOND EDGE RENDERING

    Deploy localized Edge caching to deliver instant page transitions and immediate cart updates.

  • LOCALIZED CHECKOUT

    Integrate regional payment providers (Klarna, Apple Pay, Pix) with automatic currency conversion.

  • SMART RECOMMENDATIONS

    Embed AI-driven personalization engines into the cart drawer to increase average order value.

Performance & Conversion Focus

We rebuilt the architecture around composable commerce principles, running continuous A/B testing on every micro-step of the funnel.

01

Audit & Benchmarking

Analyzed thousands of drop-off points in the previous purchase funnel to pinpoint friction points.

02

Composable Architecture

Decoupled the frontend using Next.js and Tailwind CSS, connecting to Shopify Plus APIs.

03

A/B Funnel Testing

Tested single-page vs. multi-step checkouts across global regions to maximize conversion rates.
