Subscription business model

Common versions are replenishment (products that run out), curation (boxes and discovery), access (memberships and digital content) and hybrid models that mix physical products with digital perks. What you measure changes. In a one-time model you watch orders and conversion rate. In a subscription model the key numbers are monthly recurring revenue, churn rate and customer lifetime value, because the value of a customer builds over many orders. Profit often arrives on the second or third order, not the first.
