Currently, for customer using usage for billing individual events, ie, create usage and bill it immediately, the process is to create the usage dated today, and then generate an invoice with target date = tomorrow.
Now, this works fine most of the time, but when doing this the last day or the billing period, or the last active day of the charge then, the first usage billed for the charge results in "closing" the charge, and hence subsequent usages cannot be billed for that charge during that day.
This is of course very annoying, and as more and more customer want to use usage based offering, we really need to support this!!!
