Many boutique e-commerce platforms struggle with low conversion rates. They blame marketing, product pricing, or copy. But more often than not, the culprit is checkout friction and sluggish mobile loading times. When we built the mobile-first boutique platform for Glories by Kri, we designed the entire system around speed and instant checkouts.

The Cost of 1 Second of Latency

Research shows that every additional second of page load time reduces conversions by up to 20%. Mobile users are particularly impatient. Instead of forcing users to navigate complex multi-step forms, we integrated WhatsApp and Razorpay instant checkout workflows directly into the product detail pages.

• WhatsApp-powered checkout for quick negotiation and high personalization.
• Razorpay API with saved-card and UPI quick-pay integration.
• Server-side rendering (SSR) for catalog pages to ensure sub-second First Contentful Paint.

Optimizing Data Fetching with Supabase

By using Supabase as our content management system, we kept database reads highly efficient. We implemented caching layers using React Query, ensuring that catalog listings are loaded instantly from local cache while stale-while-revalidate loops fetch updates in the background.

// React Query cache configuration
export const useProductCatalog = () => {
  return useQuery({
    queryKey: ['products'],
    queryFn: fetchProductsFromSupabase,
    staleTime: 1000 * 60 * 5, // 5 minutes
    gcTime: 1000 * 60 * 30,    // 30 minutes
  });
}

By focusing on mobile-first checkout optimization and sub-second loading speeds, we drove a 20% sales uplift within the first month. Build simple, build fast, and make purchasing frictionless.
