Penalty Clause

Penalty clauses give a contract teeth by attaching a cost to non-performance — for example, a deduction for each day a delivery is late or a service level is missed. They focus a supplier's attention on the commitments that matter most to the buyer and provide a pre-agreed remedy that avoids arguing about damages after the fact.

There is a legal nuance: courts in many jurisdictions will not enforce a clause designed purely to punish. To be enforceable, the amount should be a genuine, reasonable pre-estimate of the loss the buyer would suffer — which is why such provisions are often framed as liquidated damages. Buyers therefore draft penalties carefully and proportionately rather than setting arbitrary figures.
