What is Prompt Payment?
Prompt Payment is a term used to describe the payment conditions the State of WI is required to pay within as determined by State Statues. The State pays interest if the vendor is not paid within 30 days of receiving the invoice or the date the goods or services were received, whichever is later. If the vendor is not paid within 30 days, the interest will be paid from the 31st day after the invoice was received or the date the goods or services were received, whichever is later, until payment is made.
