The Books of Prime Entry, also known as the Books of Original Entry, are the first point of recording financial transactions in the accounting cycle. These books capture business transactions in chronological order before they are posted to the ledger accounts. They play a vital role in maintaining accurate and organized financial records, ensuring that each transaction is correctly classified and easily traceable.
1. What Are Books of Prime Entry?
The Books of Prime Entry are specialized journals where transactions are initially recorded based on source documents such as invoices, receipts, and credit notes. After recording in these books, the transactions are transferred to the appropriate ledger accounts.
Key Features:
- Chronological Order: Transactions are recorded in the order they occur, providing a clear timeline of financial activities.
- Source Documents: Entries are made based on original documents like invoices, receipts, and bank statements.
- Preliminary Recording: Before posting to the general ledger, all financial transactions pass through these books.
