35% of optimization efforts are focused to yield 51- 100% when it comes to revenue

Upselling increases the revenue by 10 to 30% on average and 70–95% of revenue comes from upsells and renewals on average — SUMO


Why should customers pay for your service? — Revenue is the last Pirate Metric in the AAARRR conversion funnel. One of the most vital measures in the revenue phase is the customer lifetime value. The measure indicates the total revenue generated by a customer over their lifetime. Calculate the customer lifetime value like this:

Customer lifetime value = Average revenue per customer * (1/churn rate)

Understanding this enables very powerful strategic revenue decisions. Everything from what to segment and behavioral patterns.


Finding the optimal customer segments is the main goal. Although you will address several segments, not all will perform very well. Identifying those segments is the primary goal of using data to make revenue decisions. At the core of this is behavioral data that trigger decisions. Decisions like when, where, and how to place a purchase, and to continue to use the service. There are three primary measures to trigger decisions:

  • How many customers become paying customers?
  • What is the average order value per customer?
  • How many repeated customers do I have and how often do they order?

This is an ideal high-level behavioral pattern to use to segment customers into the most optimal groups to target.


Focus on quality revenue, which is knowing who are your best customers and who not also pay for your services but continue to retain your services.
