A journal is a daily record of debits and credits. The General Journal is the name given to the journal that keeps such records.
A General Journal is sometimes called a posting, transaction, or daybook.
In financial accounting, the General Journal is a book of original entries that records transactions that have taken place between two dates.
The general journal is the primary source of original entries for sales, purchases, collections and disbursements, and other transactions in a business’s accounting system. The general journal contains all original accounting entries, including debits to or from inventory and cash receipts.
