The Shift in Indian E-Commerce: Mobile-First UPI Checkout

In India, 76% of all online retail transactions are completed via **UPI (Google Pay, PhonePe, Paytm)** rather than traditional credit cards. If your online store forces customers through a cumbersome 5-step checkout screen with OTP SMS delays, your cart abandonment rate will exceed 70%.
