We are implementing a new user billing cutoff date of the 10th of the month. This will allow sufficient time for the various billing cycles that need to occur around the 15th.
Please notify your clients that all adds, deletes, or changes that would affect billing that happen prior to the 10th of the month will appear on the next month’s invoice. Changes after the 10th will show up on the following month’s bill. There is definitely a win some lose some condition at play here, so it is important that your clients understand the new cutoff date.
