My problem is thus:

There is a broker company which receives commission income when selling insurances.

In the income statement, the commission received/receivable from the clients is an income item.

However, on the balance sheet, it is not the commission receivable which forms the balance under the 'Receivable' caption but rather the whole amount that the client owes [insurance amount due and commission]. Under 'Payables', it is the insurance amount due which forms the balance.

My question is:
Under the matching concept, can I have only commission received/receivable in the income statement? Or should my income be the whole amount [insurance due and commission] and my expenses be the insurance due?

Illustration of actual accounting:

Eg Client has to pay an insurance of $10,000. Out of this amount, $500 is the commission income and the rest is due to the insurance company. Actual accounting is as such:

Income Statement under Revenue:
Commission 500

Balance Sheet:
Receivables 10,000
Payables 9,500
