Definition
The purchase ledger is the accounting record of all a business's purchases made on credit and the payments it makes to suppliers — the master list of who you owe what. It is the source of your accounts-payable and creditor-days figures.
In plain terms
Every supplier invoice and payment flows through the purchase ledger, so keeping it current lets you manage payments deliberately — taking full terms without paying late, and never missing a due date.
Why it matters
A well-run purchase ledger underpins good supplier-payment management. See accounts payable and sales ledger.
