Shopify's ecosystem moves fast: Online Store 2.0, Checkout Extensibility, Markets, and B2B features change what "best practice" means each year. Treat this topic as part of your store's architecture—not a one-time checkbox.

Indian headless projects often pair Storefront API with Razorpay on custom checkout flows.

Indian shoppers expect mobile-first UX, UPI and COD options, WhatsApp support, and GST-compliant invoicing. Any Shopify implementation that ignores these signals loses conversions even if the underlying code is technically correct.
