I am trying to come up with a formula that will change my "Has been billed" column to Yes or No based on the dropdown choices in one column and the created date, I am having trouble coming up with some logic that can work around the year with sporatic billing periods. Here is my current formula:
I either have remnants from last year (March this year should be red):
But also can't just use the year marker as part of my countifs I don't think (because there is still some "last year" that needs charged):
Anyone got a clever solution?
