This module is used to close an accounting period in the system General Ledger and to move Balance Sheet account balances over to the next period. It does not need to be done promptly at the end of every month. In fact, you can leave a period open for 12 months, though RollMaster recommends closing a period within three to four months. If you do not close a period before you enter that period for the next year, you will mix prior year and current year information together. Once you close a period, you cannot reopen it or post any values. The data can continue to be viewed from the Account Detail programs.
