 Purpose of an Invoice

An invoice is a document issued by a supplier showing the invoice date, good/service, quantity, price, terms, nature of delivery, and other particulars of goods sold or of services rendered. All invoices should be processed using the State of California’s standard payment terms unless a discount is offered. Payments should generally be made within 45 days of the receipt date. State agencies/departments shall pay penalties if a correct claim is not submitted to the Controller within 30 calendar days and payment is not issued within 45 calendar days.  An invoice is a legally binding agreement showing both parties’ consent to the quoted price and payment conditions (e.g., Net 30, 5% Discount).  Invoices provide the following additional benefits:


  • Maintaining Records - Provides a record of when goods or services were rendered, the recipient, and where and when the goods or services were received.
  • Payment Tracking –Keeps track of payments and amounts owed for both the seller and the buyer.
  • Legal Protection – Provides legal proof of an agreement between the buyer and seller.
  • Receipting – Provides the date, the goods or service received.
