i am wondering if anyone has found a way to calculate  the purchase frequency for  multiple products using neto's data and reports?
there is no dedicated report for it in Neto
 
i am trying to calculate the average time between reorders(from all customers)  for each product  on the system.. in order to know what is the best time to send a reminder email for a specific product for a customer who has purchased  that product based on order history..
 
or even recommend another tool who might help with achieving this calculation
