Every Monday morning, someone on your marketing team opens three tabs: Meta Ads Manager, Google Ads, and Shopify admin. They pull numbers into a spreadsheet, do the math by hand, and present a blended ROAS that's already stale by the time the meeting starts.

If you're running a DTC analytics platform for US Shopify brands search in your head right now because your current setup can't answer "are we actually profitable this week," you're not alone.
