Headless E-commerce Development Company Building Composable Storefronts

Headless e-commerce is the architectural correct choice for high-traffic brands. By decoupling the frontend from the backend, we eliminate the speed and design constraints of traditional monolithic platforms.

• Sub-second page loads improve mobile conversion rates
• Single commerce engine serves web, app, and POS
• Unlimited design freedom via React/Next.js
• Faster deployment cycles for marketing features

Sub-Second Product Pages, Unlimited Design Freedom, and Commerce Performance That Converts the Mobile Traffic You're Paying to Acquire

• 2.5s average Shopify theme LCP on mobile headless Next.js achieves <1.5s on the same content
• 36% average conversion rate lift after headless re-platform (Shopify case studies)
• $500K+ revenue recovered annually per 1-second LCP improvement for a $10M GMV store
• 3x more content + product page variants achievable with headless vs. theme-based architecture

For a D2C brand doing $10M GMV at 2.5% conversion rate: current average Shopify theme LCP of 2.5 seconds on mobile. Moving to headless Next.js achieving 1.2 seconds LCP a 1.3-second improvement. At Google's measured 7% conversion rate increase per second improvement, that is approximately a 9% conversion rate lift worth $900,000 in additional annual GMV. The headless implementation costs $25,000-$70,000 and pays back within 2-4 months of launch.

• Traditional Shopify / WooCommerce: Days to weeks launch, 2-4s LCP, theme constraints, blog separate from products, 8,000+ apps, full Shopify admin, limited checkout customization, best for <$5M GMV
• Headless (Shopify API + Next.js): 6-14 weeks launch, sub-second LCP, unlimited React components, unified content+commerce, limited to API apps, full Shopify admin maintained, Shopify hosted checkout, best for $5M+ GMV
