From the Commission Detail Page, scroll down to the "Agent Open Balances" section. We can see that both of the agents in this transaction have open balances. The Invoice Balance column refers to open invoices on the front-end of the system (LSS). The Accounting AR Balance refers to the balance in the Accounting modules (BE Accounting and QBO). The Accounting AR Balance includes the Invoice Balance amount since invoices in the front-end of the system sync over to the Accounting side.
