Operating Account
The primary business bank account used for daily operational transactions including payroll, vendor payments, and customer receipts.
An operating account (also called a checking or demand account) is the primary business bank account used for day-to-day operational cash flows — receiving customer payments, paying vendors and employees, covering operating expenses, and managing the routine inflows and outflows of business operations. It is the financial hub of a company's daily treasury operations.
Operating accounts are demand deposit accounts — funds are available immediately on demand with no notice or penalty. They typically offer check-writing, ACH origination, wire transfer, debit card, and online banking capabilities. Unlike savings or money market accounts, operating accounts traditionally earn little or no interest, as liquidity and transactional functionality are the priority.
For larger companies, treasury best practices call for a tiered account structure: a controlled disbursement account receives payroll and vendor payment funding on a just-in-time basis; a concentration account aggregates collections from multiple lockboxes or operating locations; and a master account sits at the top of the structure, funding subsidiary accounts via automated cash concentration and disbursement.
Separating operating accounts from other funds is essential for financial control: companies typically maintain dedicated payroll accounts (funded just before each payroll run), petty cash accounts, accounts for specific projects or entities, and separate investment or reserve accounts for strategic cash holdings.
With the rise of banking-as-a-service platforms (Unit, Treasury Prime, Synapse), fintech companies and SaaS businesses can now embed operating account functionality directly into their products, enabling customers to bank within the software platform rather than through traditional banks.
FAQs
How much cash should a business keep in its operating account?
A common rule of thumb is maintaining 1–3 months of operating expenses in the operating account as a liquidity buffer. Excess cash above this target should be swept to higher-yielding instruments. The right target depends on cash flow predictability, upcoming large payments, and credit facility availability.
Should a startup have separate accounts for payroll and operations?
Best practice is to have at minimum separate payroll and operating accounts. Fund the payroll account just before each pay run to create a clear record of payroll transactions, simplify payroll reconciliation, and protect payroll taxes held in trust. As complexity grows, add dedicated accounts for taxes, capital expenditures, and investment accounts for reserve cash.
What is a zero-balance account (ZBA)?
A zero-balance account is a sub-account that is automatically funded from a master account to cover disbursements, with any excess swept back to the master at end of day — keeping the ZBA balance at zero. This allows multiple divisions or subsidiaries to have their own accounts while centralizing cash management at the master account level for maximum visibility and yield.
