The "Kill Fee": How to Invoice for Cancelled Projects

It's the email every freelancer dreads:

"We've decided to put this project on hold indefinitely. Thanks for your work so far."

Your heart sinks.

You blocked out time for this project. You turned down other clients. You may have already started the work. And now, with one short message, the project is gone along with the income you were counting on.

This is exactly why professional freelancers include a kill fee (also called a cancellation fee) in their contracts.

What Is a Kill Fee?

A kill fee is a contract clause that protects you if a client cancels a project through no fault of your own.

It ensures you're paid not just for the work you completed, but for the time you reserved. When a client books your availability, they're effectively purchasing a slot on your calendar. If they cancel late, you can't magically resell that time to someone else.

The kill fee exists to cover that opportunity cost.

Why Kill Fees Matter More Than You Think

Many freelancers assume kill fees are aggressive or "unfriendly." In reality, they're standard business practice in industries like design, consulting, and media production.

Without a kill fee:

• Clients can cancel at any time with no consequence
• Freelancers absorb all the financial risk
• Cash flow becomes unpredictable

With a kill fee:

• Expectations are clear
• Risk is shared fairly
• Last-minute cancellations become less common

Simply having the clause often prevents cancellations altogether.

Common Kill Fee Structures

There's no single correct way to structure a kill fee, but these two approaches are widely accepted.

1. Percentage of the Remaining Balance

This is the most common structure for fixed-price projects.

Example:

• Project total: $5,000
• Deposit paid: $2,500
• Remaining balance: $2,500
• Kill fee: 50% of remaining balance = $1,250

In this case, your final invoice would be $1,250.

2. Work Completed Plus a Cancellation Fee

This approach works well for hourly or open-ended projects.

The client agrees to:

• Pay for all hours worked up to cancellation
• Plus a flat cancellation fee (for example, $500)

This compensates you for both completed work and lost availability.

Sample Kill Fee Clause (Safe Version)

You don't need complicated legal language. Simple and clear works best:

"In the event of cancellation, the Client agrees to pay for all work completed to date, plus any applicable cancellation fees, subject to the terms of this agreement."

(If you work internationally, always adapt contract language to your jurisdiction.)

How to Invoice a Cancelled Project

When a project is cancelled, don't wait weeks hoping it will restart. Send a final invoice immediately.

That invoice should include:

• A clear list of work completed or hours worked
• A separate line item labeled "Project Cancellation Fee (per contract)"

Clarity matters. Vague invoices invite disputes. Itemized invoices close the loop professionally.

If a client questions the charge, you can point directly to the contract section that covers it.

"But I Don't Have a Contract…"

If you don't have a contract with a kill fee, you generally can't enforce one retroactively.

This is why freelancers should never work for $0 down.

A non-refundable deposit becomes your protection if a project disappears unexpectedly. If the client cancels, you keep the deposit and move on without chasing unpaid work.

If you're not already doing this, here's why upfront deposits are essential for freelancers.

What If the Client Refuses to Pay?

If you have a signed contract and the client refuses to pay the cancellation fee, you've entered bad debt territory.

At that point, the goal isn't emotion. It's process.

Follow a professional escalation path, document everything, and decide whether the amount is worth pursuing further. Our guide on what to do when a client won't pay walks through the steps.

Bottom Line

Kill fees aren't about being difficult. They're about protecting your time, income, and sanity.

Clear contracts, upfront deposits, and professional invoicing turn cancellations from financial disasters into manageable inconveniences.

If clients want flexibility, they can have it. But not at your expense.
