Average Payment Count

One of the most important metrics of unit economics, which determines how a customer behaves over time, their loyalty and repeat transactions. In a general sense, it is the average number of transactions a customer makes in a business.

For subscription models, it depends on the distribution of customers across plans and the average customer lifetime on a plan APC = SUM(AIS×ALT). Also, it is important not to confuse APC with months, as APC in months can be measured only in SaaS for tariff plans normalized per month. 

For the transactional model APC = 5 means that the client has made an average of 5 transactions, but the time for which he makes them is not defined, it can be 1 day, or it can be 2 years. Also the distribution of transactions by time is not defined, they could be made in an equal time interval or in an arbitrary one. 

At the same time, this metric determines how much we can earn on one client by making the same type of transactions.
