## Example

Your Shopify store recorded **\$118,500** in cart value at the payment info step this month:

| Day       | Events | Value    |
| --------- | ------ | -------- |
| Monday    | 782    | \$39,100 |
| Tuesday   | 856    | \$42,800 |
| Wednesday | 732    | \$36,600 |

## How It Works

Add Payment Info Value captures the cart total when a shopper submits their payment information during checkout. This represents high-intent revenue from visitors who have progressed past shipping and are one step away from purchase completion.
