Unique Purchases counts purchase events deduplicated by session, ensuring each session is counted only once regardless of multiple purchase events.

​
Formula

Unique Purchases = COUNT DISTINCT ( Sessions with Purchase )

Example

Your Shopify store recorded 892 unique purchases in January, even though total purchase events reached 1,024 (some sessions had multiple purchase events).

​
How It Works

The Upstack Pixel tracks purchase events when customers complete checkout on your Shopify store. Unlike total purchase event counts, Unique Purchases deduplicates by session—if a visitor triggers multiple purchase events within the same session (due to page refreshes, payment retries, or tracking redundancy), only one purchase is counted. This provides a more accurate conversion count aligned with actual Shopify orders.
