The version quoted above states that debits and credits must be entered into a ledger, so it is important that you understand what this term means, as it may be new to you. As you will see from some of the additional sources we quote, oftentimes journal and ledger are used to describe the same thing.
So, what is a ledger? A ledger is simply a collection of the accounts of your business where transactions are recorded using the double-entry bookkeeping method. If you are operating with a completely manual system, your ledgers (you will have more than one, as discussed in a moment) are on paper, usually in a bound volume preprinted in a special way to accommodate the recording of transactions. If you are using a pre-coded application software package on a PC for your accounting system, your ledgers will be on the computer.
