On the Budget page there is an option on the right side that looks like this:
If this option is turned off, then entering a transaction that is more then your envelope balance will simply cause the balance to go negative.
If the option is turned on, then when you enter a transaction that is more than the envelope balance, Budget Ease will automatically transfer money from another envelop to cover the overage. To find the money to transfer, Budget Ease will first try to take it from another envelope in the same group. If it can’t find enough money there, it will take it from your overflow envelope (usually called Savings).
