Bookkeeping is the recording of financial transactions. Transactions include sales, purchases, income, receipts and payments by an individual or organization. Bookkeeping is usually performed by a bookkeeper. Many individuals mistakenly consider bookkeeping and accounting to be the same thing. This confusion is understandable because the accounting process includes the bookkeeping function, but is just one part of the accounting process. The accountant creates reports from the recorded financial transactions recorded by the bookkeeper and files forms with government agencies. There are some common methods of bookkeeping such as the single-entry bookkeeping system and the double-entry bookkeeping system. But while these systems may be seen as "real" bookkeeping, any process that involves the recording of financial transactions is a bookkeeping process.

A bookkeeper (or book-keeper), also known as an accounting clerk or accounting technician, is a person who records the day-to-day financial transactions of an organization. A bookkeeper is usually responsible for writing the "daybooks". The daybooks consist of purchases, sales, receipts, and payments. The bookkeeper is responsible for ensuring all transactions are recorded in the correct day book, suppliers ledger, customer ledger and general ledger.
