What analysis can be gained?
This metric is useful to see how the size of your customer base, or cohorts of your customer base, changes over time.
How is it calculated?
The sum of all active customers at the end of each day. A customer is active if they are in a paid-up billing period for a subscription for which they have paid over zero-dollars.
If a customer has multiple subscriptions they will still only be counted as one customer.
If your account has the default free customer handling setting "Paying customers who move to a free plan (or are given a 100% discount) should still be classified as active subscribers" enabled, this metric will include customers with zero-dollar subscriptions.
