Accounts receivable is a legally enforceable claim for payment held by a business against its customer/clients for goods supplied and/or services rendered in execution of the customer’s order. These are generally in the form of invoices raised by a business and delivered to the customer for payment within an agreed time frame. Accounts receivable is shown in a balance sheet as an asset. It is one of a series of accounting transactions dealing with the billing of a customer for goods and services that the customer has ordered. These may be distinguished from notes receivable, which are debts created through formal legal instruments called promissory notes.
