Back Office
The back office is the part of a financial firm that handles the administrative and operational work behind transactions. It supports customer-facing and trading teams but usually does not generate trades or sales itself.

What the back office does
Common functions include confirming trades, settlement, recordkeeping, accounting, reconciliations, regulatory reporting and operational controls. The exact responsibilities vary by firm.
Simple example
A trader agrees to buy a bond. The front office makes the trading decision and executes the transaction. Back-office staff make sure the trade details match, money and securities are exchanged correctly, and the transaction is recorded.
Front office vs. back office
The front office generally includes roles that work directly with clients, markets or revenue generation, such as sales and trading. The back office supports those activities through processing, controls and administration. Many firms also use the term “middle office” for risk, treasury and trade-support functions that sit between the two.
Why it matters
A trade is not complete just because a buyer and seller agree on a price. Accurate confirmation, settlement and recordkeeping are essential to prevent errors and keep financial markets functioning.
