## Example

Your Shopify store received **1,247 orders** in January.

| Week   | Orders Placed | Change |
| ------ | ------------- | ------ |
| Week 1 | 289           | —      |
| Week 2 | 312           | +8.0%  |
| Week 3 | 298           | -4.5%  |
| Week 4 | 348           | +16.8% |

## How It Works

The Upstack Pixel tracks purchase events when customers complete checkout on your Shopify store. Each successful order fires one purchase event, which is counted and synced with your Shopify order data in real-time.
