The Project That Paid Nothing
A brand identity designer in Amsterdam took on a €12,000 project — a full brand system including strategy, logo, typography, and an 80-page brand guidelines document. The client paid a 30% deposit. Four months later, with the final deliverable two days from submission, the client emailed to say they were pausing the project indefinitely. No formal cancellation. Just a pause.
Without a kill fee clause, the designer had no basis to invoice the remaining 70%. The €8,400 owed evaporated. The designer had turned away two other projects during those four months.
A correctly drafted kill fee clause would have made the client liable for at least 75% of the remaining contract value at that stage — approximately €6,300. One paragraph in a contract, never read by either party until needed, worth six thousand euros.
What a Kill Fee Is (and What It Is Not)
A kill fee is a contractual payment owed to the freelancer when a client cancels a project after work has begun. It compensates the freelancer for:
- Work completed to date (which may be difficult to invoice precisely)
- Opportunity cost — other projects turned away to service this one
- Preparation costs — research, onboarding, tooling, meetings
- The disruption to the freelancer's business pipeline
A kill fee is not a penalty clause designed to punish the client. It is a pre-agreed estimate of the loss the freelancer will suffer if the project is cancelled. This framing matters legally: courts across the EU are more likely to uphold a kill fee drafted as compensation than one drafted as punishment.
Why Freelancers Need Kill Fees More Than Employees Do
When an employee is made redundant, employment law across the EU guarantees notice periods, severance pay, and transition protections. Freelancers have none of these by default.
The economic exposure of a cancelled freelance project includes:
- Lost revenue from the cancelled project itself
- Pipeline damage: the months spent on this project were months not spent acquiring other clients
- Sunk costs: software licences, research, third-party assets purchased for the project
- Reputational cost: projects delivered under time pressure to compensate for lost income are rarely portfolio-quality
A kill fee clause creates the contractual equivalent of a notice period. It does not make cancellation impossible — it makes it appropriately costly for the party who chose to cancel.
The Tiered Kill Fee Structure
The most defensible and commercially fair kill fee structure is tiered by project stage. This reflects the reality that cancellation at the start of a project causes less harm than cancellation the day before delivery.
Recommended Tiered Structure
| Stage at Cancellation | Kill Fee (of total project value) | Worked Example (€10,000 project) |
|---|---|---|
| Week 1–2 (discovery/kick-off only) | 25% | €2,500 |
| Work in progress — up to 50% complete | 50% | €5,000 |
| Work in progress — 50–75% complete | 75% | €7,500 |
| Final deliverable submitted or approved | 100% | €10,000 |
The kill fee applies to the total project value, not just the remaining balance. The deposit counts toward the kill fee: if the client has paid a 30% deposit and the kill fee is 50%, they owe a further 20% on cancellation.
Clause Language
Here is a practical kill fee clause in plain language:
Cancellation and Kill Fee. Either party may cancel this Agreement by providing written notice to the other party. If the Client cancels this Agreement after work has commenced, the following cancellation fees apply:
(a) Cancellation within the first 14 days of project commencement: 25% of the total project fee stated in this Agreement; (b) Cancellation after 14 days and before 50% project completion (as assessed by the Freelancer in good faith): 50% of the total project fee; (c) Cancellation after 50% project completion and before submission of the final deliverable: 75% of the total project fee; (d) Cancellation after submission or approval of the final deliverable: 100% of the total project fee.
Any deposit paid under this Agreement shall be credited toward the applicable cancellation fee. All amounts due under this clause are payable within 14 days of the cancellation notice.
Constructive Cancellation. If the Client fails to respond to written communications from the Freelancer for a period of 30 consecutive calendar days, the Freelancer may, by written notice, treat the Agreement as cancelled by the Client and invoice the applicable cancellation fee.
Kill Fee vs. Deposit: Using Both Together
A well-structured freelance contract uses both mechanisms in combination:
Deposit (paid before work begins):
- Typically 30–50% of the total project value
- Non-refundable in all circumstances
- Covers your time investment in kick-off, onboarding, and early discovery work
- Payable immediately upon contract signature
Kill fee (payable upon mid-project cancellation):
- Tiered as described above
- Calculated on the total project value
- Deposit credited against kill fee owed
- Payable within 14 days of cancellation
The deposit removes the possibility of the client "exploring" the project at zero cost — which happens more than any freelancer would like to admit. The kill fee protects you from the more damaging scenario: deep engagement, turned-away work, and then a last-minute pullout.
Deliverables and Kill Fee Payment: What to Hand Over
When a project is cancelled and a kill fee is due, two questions arise immediately:
- Does the client get the partial deliverables?
- What if they refuse to pay the kill fee?
Standard approach: Partial deliverables remain the property of the freelancer until the kill fee is paid in full. Include this explicitly in the contract:
"Partial or completed deliverables created under this Agreement remain the property of the Freelancer until all amounts due under the cancellation clause have been paid in full. Upon receipt of full payment, the Freelancer will transfer the partial deliverables to the Client in their then-current state, without warranty."
This is not punitive — it is the same logic as withholding a finished product until the invoice is paid. A cancelled-project deliverable is no different. In Germany, this right of retention is supported by §273 BGB (Zurückbehaltungsrecht). In France, the droit de rétention under Art. 2286 Code civil provides equivalent protection. In the Netherlands, §6:52 BW supports the same principle.
Enforceability Across EU Jurisdictions
Kill fees are enforceable across the EU, but courts in several countries retain the right to reduce disproportionate penalty clauses.
Germany: Under §§280, 249–253 BGB, you can claim damages for breach. Contractual penalty clauses are governed by §339 BGB — valid, but courts may reduce excessive penalties under §242 BGB. A tiered kill fee justified by actual opportunity cost is difficult to challenge.
France: The clause pénale is governed by Art. 1231-5 Code civil. French courts may increase or decrease the penalty clause amount if it is "manifestly excessive or derisory." Document your lost opportunity cost (declined projects, pipeline disruption) at the time of cancellation — this creates evidence that the fee is proportionate.
Netherlands: Penalty clauses (boetebeding) are governed by §§6:91–94 BW. Courts can reduce the penalty if they find it disproportionate in the circumstances. Again, proportionality and documentation are your protection.
Practical recommendation: Keep kill fees below 100% of total contract value for any cancellation prior to final delivery. 100% kill fees on mid-project cancellations are harder to defend. The tiered structure above has been designed to be both commercially protective and legally defensible.
When Clients Push Back
Clients sometimes object to kill fee clauses, framing them as aggressive or one-sided. Common objections and how to respond:
"We'd never cancel a project." That's reassuring — but the clause is like insurance. You hope you never need it, which is exactly why agreeing to it costs the client nothing.
"This is unfair — we should be able to cancel." You can absolutely cancel. The kill fee simply compensates the freelancer for the opportunity cost of having committed to the project. It is the contractual equivalent of a notice period.
"Our standard terms don't include a kill fee." That's fine — we'll use this contract instead.
A client who refuses to sign a contract with any kill fee clause is a client who is already planning to cancel.
