Custom eCommerce Development
For businesses that have outgrown template platforms, we build custom eCommerce platforms with the frontend decoupled from the backend (headless commerce) — built to handle large catalogs, high-traffic sales events, and fast page loads without the constraints of a standard theme.
Who it helps
Established DTC brands, enterprise retailers, and B2B distributors who have outgrown standard Shopify/WooCommerce templates and need more speed and flexibility.
What it solves
Focused implementation for the specific business problems listed below.
Overview
For growing brands and high-volume merchants seeking performant, reliable eCommerce platforms.
Scope
End-to-end architecture and development of a custom or headless eCommerce platform. Includes frontend build (Next.js), backend integration (Shopify Plus API, Stripe, Sanity), and production launch.
Outcomes
- Faster page loads, which typically reduces cart abandonment.
- A fully custom frontend design tailored to your brand rather than a modified theme.
- Backend architecture built to handle high-traffic sales events.
- Omnichannel readiness (sell across web, mobile app, and POS).
Cost & Timeline
How much does it cost?
Custom headless ecommerce builds are priced based on catalog size and complexity, checkout/payment requirements, and any custom integrations (ERP, inventory, subscriptions). Because scope varies significantly, we provide a fixed quote after a short discovery call.
How long does it take?
Custom ecommerce builds typically take 8–14 weeks given the added complexity of catalog architecture, checkout flow, and payment integration testing.

FAQ
