ACCOUNTS RECEIVABLE LEDGER, a subsidiary ledger containing the accounts of customers. In a business organ ization which sells on credit to many customers, it is impracticable to keep customers' accounts in the general ledger. The necessity of having several clerks posting the accounts at the same time makes a segregation imperative. An additional advantage lies in the greater ease with which errors can be localized. In a small business with a limited number of accounts, one accounts re ceivable ledger will suffice ; in a larger business involving many thousands of accounts, 15 or 20 customers' ledgers may be re quired. The grouping of accounts is usually arranged on an alpha betical basis; e.g., if two such ledgers are used, one would contain accounts of customers whose names start with letters from A–K, and the other, L–Z. Sometimes the grouping is arranged on a territorial basis; e.g., a separate ledger might be kept for the customers served by each branch office of a business, in which case the names would be arranged alphabetically in each ledger. The accounts receivable ledger is kept in agreement with the gen eral ledger by means of controlling account (q.v.) ; the total of the balances of customers' accounts should agree with the balance in the controlling account. Ordinarily, a separate controlling ac count is kept for each accounts receivable ledger. (See BOOK KEEPING.) (G. L. C.)
