In this article we want to dive into how revenue metrics are calculated from financial transaction data like new revenue, expansion, contraction and churn.
To calculate transaction data we need two kinds of information:
1. A way to identify each individual customer like A.myshopify.com and B.myshopify.com 2. A definition of the revenue periods we want to compare. For Shopify apps, we use 30 day periods counting backwards.
