Fill in a standard freelance service contract or mutual NDA and print or copy the text.
Contract Details
What is a contract builder?
A contract builder is a tool that fills a standard freelance service agreement or mutual NDA from the names, dates, scope, and pay you type, then lets you copy or print the text. This is a template, not a law-firm draft — have a lawyer review it before a high-value engagement.
How to Use the Contract Builder
- Select Document Type: Choose between a standard "Service Agreement" or a "Mutual NDA" using the toggle tabs at the top.
- Input Details: Fill out the required fields including your name, cell, client info, and effective dates.
- Define the Scope: Be specific in the "Services" and "Compensation" fields to avoid future scope creep.
- Export and Sign: Use the "Copy Text" button to paste into an email or e-signature software, or click "Print / PDF" to generate a clean document to send as an attachment.
How It Works: The Logic & Math
The tool uses a reactive template engine built with React. When you type your information into the input forms, it instantly maps those variables into the predefined legal text template on the right side of your screen.
Like all utilities in The Simple Toolbox, the Contract Builder is client-side. Tool inputs stay in the browser.
Real-Life Use Cases & Examples
- Onboarding New Clients: A social media manager generates a standard service agreement outlining their $1,500/month retainer, clearly defining the exact number of posts included to prevent out-of-scope requests.
- Pitching Enterprise Clients: A UI/UX designer is asked to review a confidential app design for a large corporation. They quickly generate a Mutual NDA to protect both parties' proprietary information before the discovery call.
- Securing Deposits: A freelance developer uses the contract to clearly state in writing that a 50% non-refundable deposit is required before any code is written, giving them legal backing if a dispute arises.
Who Is This For?
- Freelancers starting their first client engagement who need a professional-looking contract immediately but can't afford to hire a lawyer for a standard agreement — and don't want to start work without anything in writing.
- Experienced contractors who regularly onboard new clients and want to send a contract within minutes of a verbal agreement, before the scope creeps or the client changes their mind about the terms.
- Consultants and agencies who need an NDA before sharing proprietary information during a discovery call or proposal, but don't want to wait for their attorney to respond before a meeting that's already scheduled.
Key Benefits
- Privacy. Tool inputs stay in the browser.
- Free, no account required: Open it, fill it out, export it. No sign-up, no subscription, no per-document fee.
- Two document types in one tool: Service agreement and mutual NDA cover the two most common freelance documents without needing separate templates or tools for each.
- Print-to-PDF ready: The layout is optimized for browser printing — one click produces a clean, professionally formatted document ready to send as an attachment or for physical signature.
Common Contract Mistakes Freelancers Make
- No kill fee or cancellation clause. If a client cancels mid-project, you lose all unbilled time. Industry standard is 25–50% of the remaining contract value as a kill fee — make it explicit.
- Vague scope descriptions that enable scope creep. "Website redesign" is not a scope. "5-page redesign of the marketing site with one revision round" is. Specificity is your only protection.
- Not specifying IP ownership. Without a written clause, IP ownership can be disputed. Clarify whether IP transfers to the client upon final payment or you retain rights until then.
- No late payment penalty. The industry standard is 1.5% per month on overdue invoices. Including it in writing changes client payment behavior — most clients will pay on time when there is a stated consequence.
Once your contract is signed, use the Invoice Generator to produce a professional PDF invoice that matches your payment terms — and the Freelance Rate Calculator to confirm your quoted rate actually covers your costs before you sign anything.
