I posted a payment a day late, what do I do?
Post them in real time if you can. If it is late, the pool will still deduct the daily rate, even if the balance goes negative. Once you post the payment, the balance will be correct.
Posting payments late or early isn’t nearly as big of a problem as activating (or expiring) an event on the wrong day: in those cases ,the balance will have to be manually adjusted.
Best practice is to do everything in real time! Don’t let that new install leave the office until they have been activated!
