It has two main features for customers to choose: 1. Sweep out- An expenditure transaction is made on your behalf when the balance of the expense account exceeds the set amount. 2. Sweep in- An expenditure transaction is made on your behalf when the income account balance is set for a certain amount, but the actual account balance is less than the set amount.
