The primary book of account in which financial transactions are first recorded in chronological order, i.e., in the order in which they are entered, is called the journal. The accounting voucher, which is created on the basis of source documents such as cash memos, invoices, purchase bills, and so on, is used to record transactions in the Journal book.
Journal is the primary book of accounts. All transactions in a journal are recorded in a chronological order, that is, exactly when they occur. There are various types of special and general journals that are used in accounting. Understanding the differences between various types of entries helps us to understand these entries better.
