Contract Clause Generator for Freelancers is a startup idea for freelancers. The kill fee is the most underused freelance clause: without it, a project canceled three weeks out with only the deposit returned doesn't cover the work you turned down. A thread in r/freelance drew 49 upvotes and 15 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Bonsai, HoneyBook, and Template packs, and that still leaves this job open. Hotness is 3.00, Warm. Real but moderate pain. Some willingness to pay. The thread drew 49 upvotes and 15 comments. Gaps in existing tools. Buildable in days. A first version is weekend-easy, about 1 week, priced under $10 a month and charged as a free tier and a paid upgrade. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

How big this could get
A bottom-up estimate for Contract Clause Generator for Freelancers: real customer counts × a realistic price. Not a forecast.
$576M a year
9.6M freelancers · 15% of Americans who freelanced in the past year
$114M a year
1.9M freelancers · US, English
$1.1M a year
19,000 freelancers · 1% of the reachable segment in three years
What that means
19,000 freelancers at $5/mo = $1.1M ARR
Medium confidenceHow we estimated this
- Base: 64,000,000 Americans who freelanced in the past year.
- Has the problem: 15% (assume 15% send contracts).
- Revenue per freelancer: $60 per year ($5/mo).
- Reachable: 20% (US, English).
- Three-year capture: 1% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use Bonsai, HoneyBook, Template packs. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Weekend-easy. A tight MVP is about 1 weeks (1 week), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is freelancers. Charge a free tier and a paid upgrade, and test a price under $10 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
