A Rolling reserve</strong> is a reserve where a percentage of each transaction you receive each day is held and then released later on a scheduled basis. For example, your reserve could be set at 10% and held for a 90-day rolling period – meaning 10% of the money you receive on day 1 is held and then released on day 91, 10% of the money you receive on day 2 is held until day 92, etc.
