Bookkeeping ledgers contain a company’s principal accounting records. They hold a complete record of all financial transactions throughout the life of a business. Sometimes bookkeeping ledgers include separate or subsidiary ledgers for some types of transactions.
The general ledger includes a summary of all financial transactions within a company. The information from the general ledger comes from journals that record financial transactions on a daily basis. These transactions later become a part of the general ledger.
Large companies with numerous financial accounts often have subsidiary ledgers called creditor and debtor ledgers that record credit and debit transactions. Just the totals from the subsidiary ledgers appear in the general ledger. A company can have as many of these subsidiary ledgers as it needs to document its finances.
