A ledger[1] is the principal book or computer file for recording and totaling monetary transactions by account, with debits and credits in separate columns and a beginning balance and ending balance for each account. The ledger is a permanent summary of all amounts entered in supporting journals which list individual transactions by date. Every transaction flows from a journal to one or more ledgers. A company's financial statements are generated from summary totals in the ledgers.[2]
Ledgers include:
For every debit recorded in a ledger, there must be a corresponding credit so that the debits equal the credits in the grand totals.
Originally, a ledger was a large volume of scripture/service book kept in one place in church and accessible. According to Charles Wriothesley's Chronicle (1538):
“ | The curates should provide a booke of the bible in Englishe, of the largest volume, to be a ledger in the same church for the parishioners to read on. | ” |
It is an application of this original meaning that is found in the commercial usage of the term for the principal book of account in a business house.
