| Monday    | 134    | \$20,100 |
| Tuesday   | 112    | \$16,800 |
| Wednesday | 128    | \$19,200 |
| Thursday  | 119    | \$17,850 |
| Friday    | 145    | \$21,750 |
| Saturday  | 108    | \$16,200 |
| Sunday    | 101    | \$15,150 |

## How It Works

The Upstack pixel captures the `value` property when visitors trigger an add billing info event during checkout. This typically fires when a shopper enters or confirms their payment method. The metric sums all values to show total potential revenue at the payment information stage of your checkout funnel.
