Starting in version 15, batch posting sales invoices will now stop the entire process as soon as it encounters a posting error. For example if you are trying to batch post 2,000 sales invoices and there is an error (missing dimension, wrong date, etc.) in the 5th invoice, it will post the first 4 and leave the remaining 1,996 invoices left unposted. Microsoft's response to this is to use the background posting which might work for most folks but not when you are hitting several thousand credit cards on NAVX Credit Card.
