You are presented with a message, similar to the one below, indicates the amount of the imbalance and asks if you want to create a balancing entry against the cash over/under account.
Before continuing, please make sure you have done all steps to determine the source of a possible imbalance BEFORE using the 'Force A/R Balance' function. If you cannot "find" your error, please contact the support team prior to completing this action. Forcing an EOD imbalance and writing it off is a last resort activity and you should have at least tried redoing the end of day and checking order/transaction balances.
