rollover of unused metered billing
I would like to be able to offer a subscription for a client to pay a fixed monthly price for a certain number of hours of work which if they exhaust will result in per hour metered billing but if they don't use the full quota in a month for it to roll over for up to two months
In my primary use case it is unutilized hours but the requirement of roll over arises in South Africa for rolling over unused data bundles for two months as well
