ARPU
ARPU is the average revenue you get per paying customer over a 30-day period, net of Shopify fees. We count all types of revenues over the 30 days, including usage-based payments.
Using this formula, counting back all revenues in 30 days, we count ARPU for each source/medium or keyword daily. When viewing a period of time, we present the average of daily ARPUs in the period.
