Sub-accounts are similar to additional cardholders on credit card accounts. The benefit for an exchange is that sub-accounts create additional cardholders or buyers, which increases trade spending and therefore members with sub-accounts typically need to make more trade sales to support increased spending.

A sub-account cannot list product or service offers in the marketplace. They cannot sell, but they can spend the trade they receive from trade transfers facilitated by the main account to the sub-account, and do just about everything else the main account can do.

Sub-accounts can be zero fee accounts, or you can set a purchase fee, a sale fee or both on a sub-account. You can also charge a monthly fee for sub-accounts.
