I wanted answers Shopify's reports leave open: what a new customer is worth 30, 90 and 365 days after the first order, which first product and discount code bring back the best customers, and how long until a customer pays back what it cost to win them. Mcfly answers those from Shopify orders and the product costs Shopify already records, with no pixel and no ad logins.
