Set Monthly Budget alongside daily budget -or- change billing dates
The monthly budget limit is based on your daily budget for the billing dates, which we cannot set. This means that we could actually go over our monthly budget (i.e. Dec 1-31) but Bing won't do anything about it because they are running on a different timing. My daily budget has consistently been at least $10 higher than the daily budget I have set, which means I have now lowered that in hopes of not going over.
If we have the option of setting a monthly budget alongside a daily budget, or at least change the billing dates to match our billing cycle, this will help with reporting metrics and keeping track of the budget.
