Likely cause: Differences in how revenue is calculated — Shopify reports gross revenue including taxes and shipping by default, while Upstack reports the Purchase event value as sent by the pixel, which typically reflects the cart subtotal. How to reconcile:
  1. In Shopify admin, go to Analytics → Reports and export the order data for the time range you’re comparing.
  2. Note whether Shopify includes taxes, shipping, discounts, and refunds in the total.
  3. In Upstack, the Purchase event captures the value property from the checkout. This usually equals the cart subtotal before tax and shipping.
  4. To compare accurately:
    • Shopify gross revenue minus taxes minus shipping should approximate Upstack’s reported revenue.
    • If you’ve configured Upstack to include tax/shipping in the event value, the numbers should be closer.
  5. Refunds also cause drift — Shopify retroactively adjusts revenue, while Upstack records the purchase at the time it occurred. Check Events → Purchase and filter by the date range to see the raw event values.
