Key details at a glance
Shopify fits brands under ₹5Cr/month GMV — low upfront cost, quick to launch, though with transaction fee overhead long-term. Headless architecture fits the ₹5–50Cr/month GMV range — custom checkout UX, Next.js storefront performance, and the best page speed scores. Full custom builds fit brands above ₹50Cr/month GMV — complete stack ownership, no per-transaction platform fees, full business logic control. The "rebuild trap" — don't over-build before you have the GMV to justify it. The right platform today is often the wrong one at 10x scale.
