Revolving credit means that your credit limit is automatically renewed as soon as your outstanding is paid off.
e.g. You may have obtained an approval for RM100,000.00 limit. Three (3) of your invoices total valued at RM100,000.00 are being factored or financed. Since it is being factored/financed, you have no available credits at this time. Your credits will be available again, once your outstanding is paid off.
