How to write a liquidated damages clause for missed deadlines

A client wanting a liquidated damages clause for missed deadlines is usually protecting themselves from a real business risk, a launch date, a dependent event, a downstream commitment they've made to someone else. An unbounded or poorly scoped version of that clause can expose you to damages far beyond what the engagement itself is worth.

A fair liquidated damages clause isn't the absence of consequences for a missed deadline. It's one scoped to a genuine, defensible estimate of actual harm.

An unbounded penalty clause exposes you far beyond the engagement's value

A liquidated damages clause with no cap can theoretically expose you to a liability many times larger than the fees you're actually being paid. Recognize that risk before accepting boilerplate language drafted entirely around the client's protection.

Understand the real business risk the client is trying to manage

Ask directly what specific consequence a missed deadline would actually cause, a dependent launch, a contractual obligation of their own. Understanding the real risk shapes whether the clause as drafted is proportionate to it.

Tie it to a genuine pre-estimate of harm, not an arbitrary penalty

A liquidated damages figure that's legally defensible reflects a genuine, reasonable pre-estimate of actual harm from a delay, not a number chosen to be punitive. An arbitrary penalty figure is both unfair and, in many jurisdictions, actually unenforceable.

Cap it at a reasonable proportion of total fees, not an unlimited number

Cap the total exposure at a defined, reasonable proportion of the engagement's fees, so a delay, even a real one, can't produce a liability disproportionate to what you're being paid. This is the single most important protection in the clause.

Carve out delays caused by the client or events outside your control

A missed deadline caused by the client's own delayed feedback, or by a genuine force majeure event, shouldn't trigger a penalty meant for delays you actually caused. Explicitly carve out delays outside your control from the clause's trigger.

A simple checklist

If you do nothing else, do these five things:

• Understand the real business risk the client is protecting against.
• Tie the figure to a genuine pre-estimate of harm, not a penalty.
• Cap total exposure at a reasonable proportion of total fees.
• Carve out delays caused by the client or outside your control.
• Don't accept boilerplate language without reading the real exposure.

Do that, and a liquidated damages clause protects the client's real risk fairly, without exposing you to liability far beyond what the engagement is worth.
