Sub-accounts

Introduction

A sub-account is a virtual account tied to a customer's main account. Customers can transfer money between their main account and sub-account(s) without triggering the change request process. For example, you can use sub-accounts to offer freelance customers dedicated sub-accounts for tax and VAT savings and add or remove money from these savings.

Please note the following behavior of sub-accounts:

  • Customers cannot initiate outgoing SCTs from sub-accounts, and they cannot have funds debited from sub-accounts via SDDs.

    • To transfer money between the customer's main account and a sub-account, or between sub-accounts, you must use intra-customer transfers (ICTs).
  • Customers cannot use funds from sub-accounts in card transactions.
  • Solaris does not include sub-accounts in calculating a customer's balance or available balance.
  • Funds stored in sub-accounts are considered in seizure processing.
  • Solaris may request limitations on the number of sub-accounts per customer.
note

This feature is not enabled by default. If you're interested in offering sub-accounts to your customers, then please contact your Partner Manager.

Sub-accounts integration steps

Prerequisites

Before you can open sub-accounts for a customer, they must have completed the identification and onboarding process. See the get started guide for instructions.

Step 1: Confirm Solaris Terms & Conditions

For each new account, you must collect the customer's consent to the Solaris Terms & Conditions. See the Legal and compliance screening guide for instructions on how to implement this screen.

Store a UTC timestamp from when the customer agreed to the Terms & Conditions document, as well as the ID of the document, in your solution. You must provide this information to Solaris upon request.

Step 2: Create sub-account

To open a sub-account for your customer, visit the following links to find more information about the account opening process:

note

You must set the type of the account to either CALL_MONEY or CHECKING_SUBACCOUNT. Please contact your Partner Manager for more information.

Step 3: Intra-customer transfer

Unlike with regular bank accounts, funds can only be transferred to and from sub-accounts using POST Create intra-customer transfer.
