Purchase on account

A purchase on account is recorded by debiting what you received (Supplies, Equipment, Inventory or an expense) and crediting Accounts Payable for the amount owed. The liability stays on the books until you pay, when you debit Accounts Payable and credit Cash.

Common mistakes

  • Debiting an expense for an asset: equipment or supplies bought to use later go to an asset account and become expense as they are used or depreciated.
  • Crediting Cash when nothing was paid: a purchase on credit credits Accounts Payable; Cash is credited only when the bill is settled.
  • Recording a purchase of inventory as Purchases under a perpetual system: perpetual systems debit Inventory directly; the Purchases account belongs to the periodic system.

Questions

Is accounts payable a debit or a credit?

Accounts Payable is a liability with a credit normal balance. It is credited when you buy on account and debited when you pay.

What is the difference between accounts payable and notes payable?

Accounts payable arises from ordinary supplier invoices with no formal document. Notes payable is backed by a signed promissory note and usually carries interest.
