Cash credit or bank overdraft is the most useful and appropriate type of working capital financing extensively used by all small and big businesses. It is a facility offered by commercial banks whereby the borrower is sanctioned a particular amount which can be utilized for making his business payments. The borrower has to make sure that he does not cross the sanctioned limit. The best part is that the interest is charged to the extent the money is used and not on the sanctioned amount which motivates him to keep depositing the amount as soon as possible to save on interest cost. Without a doubt, this is a cost-effective working capital financing.
