Treasury management is the set of bank services that help a business control, move, and protect its cash — ACH origination, wire transfers, sweep and zero-balance accounts, lockbox processing, and fraud-prevention tools like positive pay. Banks typically offer treasury management to established, higher-balance or higher-transaction-volume business customers as part of a full banking relationship, often alongside deposit accounts and lending.
Treasury management (also called cash management) covers the operational side of business banking: moving money efficiently, keeping idle cash working, and preventing payment fraud. It sits alongside — and is often bundled with — a bank's deposit and lending relationship with a business, and is typically offered to businesses with meaningful transaction volume or cash balances rather than to every small deposit customer. Core services include: ACH origination, which lets a business push payroll, vendor payments, or customer debits directly through the ACH Network under the Nacha Operating Rules that govern every participating bank; wire transfers, same-day, irrevocable fund transfers governed by UCC Article 4A, used for large or time-sensitive payments (real estate closings, payroll funding, large vendor payments); lockbox processing, where customer payments are mailed to a bank-operated address and deposited directly, speeding up collections for businesses with high check-payment volume; and sweep accounts / zero-balance accounts (ZBA), which automatically move excess operating-account cash into an interest-bearing account or against a line of credit balance at the end of each day, then sweep it back the next morning — keeping idle cash productive without manual transfers. Fraud-prevention treasury tools matter as much as the payment-movement tools. Positive pay lets a business submit its issued-check register to the bank in advance; the bank flags any check presented for payment that doesn't match (wrong amount, altered payee, unauthorized check) before paying it — a standard defense against check fraud and business email compromise schemes. ACH debit blocks and filters let a business restrict which originators can debit its account, protecting against unauthorized ACH withdrawals. Relationship context: banks typically price treasury management as a bundle of per-transaction and monthly service fees rather than a flat product, and often waive or discount fees for businesses that maintain compensating balances or a broader lending relationship. Businesses evaluating banks for a line of credit or term loan frequently negotiate treasury management pricing as part of the same relationship discussion (see bank statement analysis for how lenders read a business's existing cash-management activity during underwriting).
No, though it's typically offered to businesses with meaningful transaction volume or cash balances rather than every small deposit customer. Many banks offer scaled-down treasury management packages (ACH origination, positive pay) to established small and mid-sized businesses, especially those with payroll, high check volume, or fraud exposure — not just large corporate treasury departments.
A wire transfer, governed by UCC Article 4A, is same-day and irrevocable once executed — used for large or time-sensitive payments where certainty matters more than cost. An ACH payment, governed by the Nacha Operating Rules, batches and settles within one to a few business days, costs less per transaction, and is reversible within limited windows — used for routine payroll, vendor payments, and recurring debits.
The business submits its register of issued checks (check number, amount, payee) to the bank in advance. When a check is presented for payment, the bank automatically compares it against that register and flags any mismatch — an altered amount, forged payee, or a check that was never issued — for the business to review before the bank pays it, rather than paying first and disputing fraud after the fact.
