What defines a Zero Balance Account (ZBA)?

A Zero Balance Account (ZBA) is designed to maintain a balance of zero at the end of each business day. To achieve this, any necessary funds are automatically transferred from a master account to the ZBA as needed to cover checks or other transactions that day. If the account has transactions that cause it to have a positive balance, funds are transferred back to the master account at the end of the day, thereby keeping the ZBA balance at zero. This mechanism helps organizations manage their cash flow efficiently by minimizing idle cash in checking accounts and maximizing the funds available for investment or other uses.

The nuances of a ZBA highlight its purpose—streamlining cash management while effectively utilizing available resources.
