What is a Ledger?
A ledger is a book or place where all transactions related to one account are collected together.
Journal records transactions date-wise.
Ledger arranges the same transactions account-wise.
Example: if Cash is used in many transactions, the Cash Account in the ledger shows all cash received and all cash paid in one place.
Simple line: Journal tells the story transaction by transaction. Ledger groups the story account by account.
