Invoice

Definition

An invoice is a document issued by a supplier after a purchase, detailing the goods or services provided and the payment terms, usually due within 30 to 90 days.

From the buyer’s perspective, the invoice-to-pay (I2P) process covers all steps from when the buyer receives the invoice until payment is made. From the supplier’s perspective, this is part of the invoice-to-cash (I2C) or order-to-cash process.
