A procurement professional is drafting payment terms for a commercial contract.

Retention money is the payment for a service or product that is withheld pending the completion of some specified condition. For example, buyer may withhold the amount due until the supplier replace all defective goods.

Pay-less notice is the notice under a contract which states that the invoice will only be partially paid because of some issues such as supplier has to pay the damages.

Remedies for late payment are remedies that supplier may seek when a buyer pay it later than the stated payment terms. Normally, the buyer will be charged an interest rate.
