What is the Revenue source from Shopify that you are using for Revenue and Cohort metrics?

Peel pulls in Total Sales. We sum up the Total Sales value for all the orders of all the customers in each Cohort and then we build the Cohorts based on the date of the first purchase. This includes all Revenue - both Transactional and Subscription Revenue will be joined together as a default.

Total Sales = Gross Sales - Discounts - Returns + Taxes + Shipping charges
