Customer Role With a validity date

Hi
I have created 4 customer roles each role will be assigned based on the purchase the customer make.
but the problem is each purchase is of 1 month validity. is there a possibility where the system can remove the customer role after a period of time automatically. Hope I am clear.

thanks in Advance
Regards
Praveen

There is no intrinsic feature that would do this. You would either need to create a plugin, or create a sql sproc and run it on a schedule.

Maybe, instead of using customer roles, you can utilize the "rental" feature for products. This allows to set a 1 month expiration... http://docs.nopcommerce.com/display/en/Rental+Product
