If I postpone a renewal date from June to July, what month will MRR include the revenue?

If a subscription's renewal date is postponed, then the revenue from that renewal date would only be counted during the month that the charge takes place.

For example, if you have a $100 subscription that was supposed to renew June 1, but is postponed to renew on July 1 instead, moving that renewal date would reduce the current June MRR by $100. It would be counted toward MRR again starting July 1.
