Let's say I have customerA, ordering 128 times in the last 12 months, payment term is 30 days. He orders 8 times per month, but one month he ordered 40 times. The average amount of orders during 30 days is not 128/12 (if we consider one month=30 days) It'll be more around 8 then. + the payment term "30 days) will be different according to each customer.

I think I need to create a loop where, every day between today and 12 months ago, PBI will calculate amount of orders on the said duration (in my example above 30 days) and will return the average of those calculations.

    You could look to create buckets of the appropriate size for each customer. If you iterate over the customer table you could try something like

    var paymentTerms = SELECTEDVALUE(Customer[payment terms])
var summaryTable = ADDCOLUMNS(
GENERATESERIES( TODAY() - ( 12 * paymentTerms ), TODAY(), paymentTerms),
"@num orders", CALCULATE( COUNTROWS( Orders), DATESBETWEEN( 'Date'[Date], [Value], [Value] + paymentTerms) )
)
return AVERAGEX( summaryTable, [@num orders])
