FAQ

Shopify commerce development involves building, customizing, and optimizing Shopify stores to maximize conversion rates, revenue, and customer experience. We specialize in Shopify Plus development, including checkout extensions, custom store builds, headless commerce, and performance optimization.
We offer comprehensive Shopify development services including custom store development, checkout extensions and functions, subscription implementations, headless commerce solutions, and performance optimization. Each service is tailored to help Shopify Plus merchants scale their business and improve conversion rates.
We use Shopify's native Checkout Extensions, which include Functions (server-side Rust code) and UI Extensions (React components). This allows us to modify checkout logic, add custom fields, implement smart upsells, and create discount functions without relying on private apps or third-party solutions.
Shopify Plus is the enterprise tier that provides access to checkout customization (Functions and UI Extensions), lower transaction fees, dedicated support, advanced APIs, and features like Script Editor and Launchpad. Regular Shopify plans don't support checkout extensions, which limits customization options.
Timeline depends on project scope. A simple modifications might take same day turnaround, while a full custom store build could take 8-12 weeks. We provide detailed timelines during discovery based on your specific requirements and priorities.
Headless commerce separates the frontend (customer-facing storefront) from the backend (Shopify's commerce engine). This allows you to build custom frontends using any technology (Next.js, React, etc.) while Shopify handles inventory, payments, and order management. It provides maximum flexibility for unique brand experiences.
We optimize performance through code splitting, image optimization, lazy loading, reducing JavaScript bundles, optimizing Liquid templates, implementing proper caching strategies, and improving Core Web Vitals. We also audit third-party apps that may slow down your store and recommend alternatives.
