I did a little more research and found a few more cash management services:
Zero Balance Account: This is a system that was created for large retail chains. Each branch is then assigned an account number and management makes store deposits into those individual accounts. At that point, all of the deposits are then swept into the main account, allowing the home office to see sales totals for each subsidiary. Using the “ZBA” system is appealing because businesses are able to obtain better interest rates.
Lockbox: Companies that receive a large amount of payments via mail can have their bank check their mail and deposit all incoming checks.
Account Reconciliation: Large businesses may find it difficult to reconcile their accounts and determine their true balance. Banks have developed a statement system that shows all of the checks that have cleared as well as those that have not. ~Moderator Mel
