Sub Account

A Sub Account is a real funding account used to isolate funds by department, project, or business purpose. A business can transfer funds from the Primary Account to different Sub Accounts and then allocate Budgets from the Sub Accounts.

The Sub Account funding model is:

Sub Account Total Amount = Available Balance + Allocated Budget Limit + Frozen Amount

Field	Meaning
Available Balance	The amount that can still be transferred or used to allocate a Budget
Allocated Budget Limit	The total Budget Limit allocated to Budgets under the Sub Account
Frozen Amount	The amount temporarily frozen at the account level

The transferable amount is based on the Sub Account Available Balance. The Allocated Budget Limit and Frozen Amount cannot be transferred directly. Frozen Amount belongs to the account level and is not the same as an authorization amount in a Card transaction.
