What is a sales ledger?
Definition of a sales ledger
A business's sales ledger is a list of all the sales invoices it's ever issued and when they were paid.
Before computerised accounts came into being, a business's clerks would write up its sales and receipts in a thick leather-bound book. That's why this list is called the "sales ledger".
The total amount of invoices in the sales ledger that haven't been paid yet is the business's figure for trade debtors.
