Overview
You can set a rolling minimum charge on any meter using the meter price type "rolling minimum". When you do this any quantity less than the minimum is carried forward into future periods.
When implementing the Rolling minimum meter product price, the difference between the actual and minimum quantity can be carried forward as a potential credit at the minimum price rate where the actual quantity is less than the minimum quantity for a meter on a charge run.
If the actual count is under the rolling minimum, a credit will be created.
If the count is over the rolling minimum and you have credits carried forward you can consume the credit.
Formula for one meter count run for a period for the one machineid/meters = (actual count * actual meter product price) + ((rolling minimum quantity - (actual count) * rolling minimum meter product price)) (for one meter count run
Formula for multiple meter count runs for a period for the same machineid/meters = (sum(actual count variances) * actual meter product price) + ((rolling minimum quantity - (sum(actual count variance) * rolling minimum meter product price))

A machine or total machine has a minimum quantity of 1000 mono prints a month at $0.009 per copy. The minimum is setup using a meter price of type "rolling minimum"
In the first month the site only uses 800 mono prints. So they are charged the count and the minimum. A second line is generated on the invoice showing that a rolling minimum of 200 at $0.009 per copy.
The price per copy changes to $0.01 in the second month.
In the third month, the site uses 1500 mono prints in the month. The full 1500 is charged at the current rate of $0.01 per copy. Then a second line is printed on the invoice showing a credit of 200 at $0.009 . The site has used up the credit that was carried forward from month one for being under the minimum.
The machine is eventually refinanced. At which time the user may cancel any outstanding credits that are stored for the machine.
