Tool #360 "End of Month Processing" should be used by your credit union whenever you have finished posting entries to your books for a particular month and want to prevent additional entries from being posted accidentally.  Refer to the "Closing Your Books" link below for details about what happens when you use this feature.

NOTE: This is not to be confused with the month-end processing that is done by CU*Answers Operators every month for online CUs (or by self processors) on the last day and first day of every month.  (That month-end includes all sorts of other monthly procedures and tasks, including statement processing, etc.)  The feature we're talking about here is Tool #360 and must be run manually by the CU on the date during the month whenever you have finished making entries to the prior month's books.  This might be the 10th or whatever date you decide (some credit unions draw the line when they prepare the financials for the Board, for example).   It only relates to your general ledger.
