Whenever you have to collect a component (typically for a commission or charge, or under certain circumstances the availment amount or the collateral amount), you debit it from the customer’s account. On some occasions, you may have to debit it from an internal receivable GL, is debited from the customer account at a later date.

The debiting of the receivable account happens at the event for which the commission or charge has to be collected (issue of an Islamic LC, amendment of an Islamic LC, availment against an Islamic LC, etc.). When the customer account is debited at a later date, you have to perform, what is termed as receivable liquidation.
