Why businesses use ZBAs
They can separate payroll, disbursement or collection activity without leaving idle cash scattered across multiple accounts.
Typical structure
| Account | Role |
|---|---|
| Master operating account | Central liquidity pool |
| Payroll ZBA | Funds payroll as needed |
| Disbursement ZBA | Covers checks/ACH disbursements |
| Collection ZBA | Sweeps receipts to master |
Control benefit
Because the subaccount does not need a large permanent balance, the company can centralize liquidity while preserving separate transaction streams and permissions.
Questions for the bank
Ask about sweep timing, intraday overdraft handling, reporting, account-analysis charges, earnings credit treatment and whether the structure works across legal entities.
Not the same as a consumer zero-fee account
“Zero balance” here describes treasury concentration mechanics, not an account with no minimum balance or no monthly fee.
Primary sources and reference material
Design treasury around controls and exceptions, not only speed.
The strongest treasury setup combines the right payment rail with role separation, verification, reconciliation and enough visibility to catch unusual activity before it becomes a loss.
