Operating Account

Trade Finance and B2B PaymentsUpdated 15 Nov 2026

An operating account is the bank account that a business uses to run its day-to-day affairs: receiving its own revenue, paying salaries, rent, suppliers and taxes, and holding working cash. It is usually a current or checking account with full payment features, such as transfers, direct debits, cards and online banking. Almost every company has at least one, and larger groups hold many across entities, currencies and banks.

In payments and financial services, the term has a sharper meaning. A payment company, money transmitter, e-money issuer, exchange or marketplace handles two kinds of money: its own, and money that belongs to its customers. The operating account holds the firm's own funds, while customer money must sit in separate accounts such as a safeguarding account or an FBO account. Keeping these apart is one of the most important controls in the industry.

01

How operating accounts are used

Typical flows through an operating account include:

Treasury teams monitor operating account balances daily, forecast inflows and outflows, and keep a buffer to cover payments while investing surplus cash. Many companies use separate accounts for specific purposes, such as payroll or tax, to simplify control and bank reconciliation.

02

Operating accounts in payment businesses

For regulated payment firms, the operating account is one of several account types, each with a defined role:

  • Operating account. The firm's own money, from which it pays its staff and costs and into which it moves the fees it has earned.
  • Customer funds or safeguarding account. Money received from or for customers, protected so it can be returned if the firm fails, described under safeguarded client funds.
  • Settlement account. An account used to settle with card schemes, clearing systems or partners, such as a settlement bank account.
  • Reserve and collateral accounts. Funds held as security by acquirers, sponsor banks or schemes, such as a reserve account.

Fees are typically calculated in the customer ledger and then transferred from the customer account to the operating account on a regular schedule, once they have been earned. The firm's own money may also be moved into a customer account to cover a shortfall, but customer money should never flow the other way except as permitted fees or repayments.

03

Commingling and its risks

Commingling means mixing customer money with the firm's own funds in the same account. Regulators in most regimes forbid it, because if the firm becomes insolvent, money in its operating account is generally available to its creditors, while properly safeguarded customer money is ring-fenced for customers. Commingling also makes it easy, deliberately or accidentally, to use customer funds to pay the firm's expenses.

Several high-profile failures of payment and crypto firms involved customer money held in, or moved into, operating accounts, leaving customers facing long delays or losses. As a result, supervisors examine account structures closely, require daily or frequent reconciliation between customer ledgers and safeguarded balances, and expect clear records of every transfer between customer and operating accounts.

04

Opening and maintaining operating accounts

For ordinary businesses, opening an operating account involves standard know-your-business checks. For payment firms, money transmitters and crypto companies, banks apply enhanced due diligence because of the higher money laundering risk, and some banks decline such clients altogether. A firm may need an MSB bank account from a bank that specialises in these sectors, and losing that relationship can disrupt the whole business. Firms therefore often keep operating accounts with more than one bank, and they plan contingency arrangements in case a bank exits the relationship.

05

Good practice

Common controls for operating accounts include dual authorisation for payments above set amounts, separation of duties between staff who set up payees and those who approve payments, daily balance monitoring and monthly reconciliation. For payment businesses, account names should make clear which accounts hold customer funds, internal policies should define exactly which transfers between account types are allowed, and auditors should be able to trace every movement between them as part of wider treasury management.
