Open a client money account
A client money account is for managing your customers' funds. Only firms regulated under CASS (the FCA's Client Assets Sourcebook) can open client money accounts. You can choose to open a dedicated account for each of your customers, or a pooled account for holding funds from multiple customers. Learn more about bank accounts.
Prerequisites
You will need your
organization-bank-accounts-url(shown as$ORGANIZATION_BANK_ACCOUNTS_URLin the examples below). Yourorganization-bank-accounts-urlis one of the URLs returned when you request yourorganization-url. If you don't have yourorganization-urlyet, check out our getting started guide.Before you can open an account for a customer, you must determine the legal relationship that your customer has with the account. Learn about owners, controllers and beneficiaries. Any named owner or beneficiary will need to be onboarded. Check out our guides for onboarding customers.
