A checkout that matches how people actually pay

Not every payment is straightforward. Sometimes your card limit won’t cover the full amount. Other times, you want to use up a wallet balance before switching to UPI. In most checkouts, there’s no way to do this — you either switch payment methods or abandon the purchase altogether.

Stack & Pay fixes that.
It lets customers split a single order across multiple payment sources — seamlessly and within the same checkout flow.

One payment, multiple methods

Stack & Pay introduces a simple new behavior:
choose how much to pay with one method, pay it, then continue with another.

This can include:

• Paying ₹1,000 via UPI, then ₹500 via card

• Combining a gift card with a wallet

• Stacking two different debit cards

• Or any other combination

Each “slice” is paid one at a time, with live progress shown throughout.

Built for high flexibility, zero friction

There’s no need to restart the flow or manually top up balances. Stack & Pay handles partial completions, progress tracking, and confirmation at every step — all inside a single session. It works out of the box with SuperCheckout’s drop-in or embedded SDKs and doesn’t require any changes to your payment gateway or backend.

You can enable it directly from your SuperCheckout dashboard.

/* Prabhu ji we can insert code snippets too 
using CMS so good for developer related blogs too!!

import { initSuperCheckout } from "@supercheckout/sdk";

initSuperCheckout({
  amount: 2999,
  mode: "stack-and-pay",
  onSuccess: () => console.log("Payment complete!"),
});

Real-world use cases

Stack & Pay is especially helpful for:

• High-ticket purchases — where customers may prefer splitting between multiple cards

• Young users — who often use a mix of wallets and saved balances

• Shared expenses — where one person may cover part before sending the link to others

• Wallet exhaustion — letting customers deplete low balances before switching

We built this for real-world scenarios — not just ideal ones.

Available today

Stack & Pay is live and available to all SuperCheckout merchants. You can enable it from the Features tab in your dashboard. No extra setup required.
