The Problem

You don't have a sales problem. You have a checkout problem.

Your products are ready to sell but your checkout experience could be stopping customers from completing their purchase. From fake COD orders and abandoned carts to slow checkouts and disconnected tools, every friction point impacts conversions, customer trust, and profitability. A smarter Shopify Checkout App helps eliminate these barriers and keeps more customers moving from cart to order.

Reduce Fake COD Orders Before They Ship

Cash on Delivery helps increase sales, but it can also lead to fake orders and costly returns. With the MSG91 Shopify Checkout App, you can collect a small upfront payment to verify buyer intent, reduce return-to-origin (RTO), and ship every order with confidence.

  • Collect a configurable upfront payment to improve buyer commitment.
  • Reduce fake COD orders and lower return-to-origin (RTO) costs.
  • Works seamlessly with your existing Shopify checkout and payment gateways.
  • No coding required—install and start in minutes.

Up to 30% Lower Return-to-Origin (RTO) Risk

Convert More Customers at Checkout

A slow or complicated checkout can drive customers away at the final step. Customize your Shopify checkout with a native Shopify Checkout Extension that removes friction, simplifies payments, and helps more shoppers complete their purchase.

  • Personalize your Shopify checkout without custom development.
  • Reduce checkout abandonment with a faster buying experience.
  • Compatible with Shopify Payments, Razorpay, Stripe, PayU, and Cashfree.
  • Go live quickly with a native Shopify Checkout Extension.

Numbers don't lie.Neither do our customers.

Every other checkout tool wanted a monthly fee before we'd placed 100 orders. MSG91 charges only when we do. That's the only fair model.
