Currently, there is no charge model avaialble to bill customers monthly if they go over their overage/limit, and we have to wait for 6 months or a year inorder to issue the invoice & some customer can't wait that long to have their invoices issued that late when they know they have gone over their usage limit months ago. It would be great to have such charge model available as lots of customers have billing frequency of monthly and go over their annual limit few months into the contract.
