Once a Shopify brand crosses roughly $10M in annual revenue, the analytics stack that got them there quietly stops working. Native Shopify reports lag. Attribution tools that were fine at $3M start showing gaps. The spreadsheet someone built in year two to blend ad spend and Shopify orders now takes half a day to update. This is the point where founders start googling for the ecommerce analytics used by Shopify brands doing $10M plus, because the DIY approach has run out of runway.
