Accounts receivable is one of a series of accounting transactions dealing with the billing of customers who owe money to a person, company or organization for goods and services that have been provided to the customer. This is typically done in a one person organization by writing an invoice and mailing or delivering it to each customer.
On a company's balance sheet, accounts receivable is the amount that customers owe a business. Sometimes called trade receivables, they are classified as current assets. To record a journal entry for a sale on account, one must debit a receivable and credit a revenue account. When the customer pays off their accounts, one debits cash and credit the receivable in the journal entry. The ending balance on the trial balance sheet for accounts receivable is always debit.
