# Why Attribuly's ATC data is more than my Shopify dashboard?

# Question:

I have compared the add-to-cart data between my Shopify admin and Attribuly, why do I see higher ATC conversions at Attribuly?

# Answer:

Attribuly and Shopify use different definitions for the conversion data.

Let's say you have a customer just visit your site, and put 5 products in the cart.

Shopify: The number of sessions that resulted in Added to cart. So you will see **1 session** in this case.

Attribuly: The number of ATC actions the customer has taken. So you will see **5 ATC events** in Attribuly. The data is 5 times more than Shopify's.

Attribuly is an event-based analytics, which dives deeper into customer behaviors rather than a session of page hit.
