Account Receivable basically refers to the amount that customers owe to an entity once they purchase goods or rendering services on credit. In most cases, these receivables are expected to be collected in less than one year.
However, in some cases, those receivables could not collect in less than one year. We can know these based on the business practices, contract, or agreement.
In the case that receivable could no collect in less than one year, the account classification could be classified into non-current assets at book value.
