Merchant account
A specialised account provided by an acquiring bank that enables the acceptance and settlement of electronic card payments, holding funds temporarily prior to payout.
Institutional definition: A merchant account is a settlement account used by acquiring banks to receive card transaction proceeds on behalf of a merchant before funds are remitted. It is not a standard business current account and exists primarily to manage settlement timing, chargeback risk, and scheme compliance.
Risk context: Funds held within a merchant account remain subject to reversal, dispute, or withholding. As a result, merchant accounts function as a risk buffer for acquirers rather than as deposit accounts for merchants.
Institutional scope
Merchant accounts are issued and managed by institutions including:
- Acquiring banks
- Card scheme member banks
- Payment institutions acting as sponsored acquirers
- Embedded finance platforms operating settlement accounts
The merchant account represents the contractual point at which transaction liability, settlement timing, and chargeback exposure are defined.
Relationship to business bank accounts
A merchant account is distinct from a business current account. While business accounts store cleared funds, merchant accounts temporarily hold unsettled card proceeds.
Settlement delays, rolling reserves, and account freezes occur at the merchant account layer, not at the merchant's primary banking relationship.
Settlement mechanics
Authorisation
Transactions are authorised by the issuing bank but not yet settled, creating provisional obligations.
Clearing and holding
Authorised funds are routed to the merchant account, where they remain subject to scheme rules and dispute windows.
Payout
Funds are transferred to the merchant's business account after settlement timelines and risk checks are satisfied.
