The double entry transactions are recorded in the ledger accounts. Please remember that the Books of Original Entries & ledgers are different things. Every financial transaction is recorded on the double entry system in at least two ledger accounts.
Types of Ledgers
There are three different kinds of ledgers that businesses keep:
=> Sales Ledger
=> Purchase Ledger
=> General Ledger
The Sales ledger are customer accounts that are maintained separately for every customer.
Firstly a credit sales transaction is recorded in the Sales Day book which is the book of original entry.
Next it is posted as double entry in the customer account (sales ledger) and the Sales Account.
Dr. Customer Account(Sales Ledger) $xxx
Cr. Sales Account (General Ledger) $xxx

In the above example of ledger accounts, the entry relates to a transaction in which $5,000 Sales is made to a customer named ABC. The Customer Account is titled ABC A/c above as you can see the debit entry that suggests receivables and a credit in Sales account (a revenue account).
Purchase Ledger is the Account of Suppliers that is a concern maintain in its books of accounts.
First the Credit Purchase transaction is recorded in detail in the Purchase Day book that is the book of Original Entry.
Next it is recorded as double entry transaction in the Purchase Ledger (Supplier Account) and the Purchase Account (General Ledger).
The Double Entry Transaction will look like this:
Dr. Customer Account (Purchase Ledger) $xxx
Cr. Purchases (General Ledger) $xxx
The General Ledger contains all the accounts other than the supplier & customer accounts (Purchase ledger & Sales Ledger). Revenue & Expenditure accounts, fixed assets, retained earnings accounts are the examples relating to the General Ledger or often referred simply as ‘Ledger’.
