Freelancer Contract Checklist: What to Have Signed Before You Start

Why freelancers need contracts

A verbal agreement is legally enforceable in most countries, but nearly impossible to prove. Without written contracts, disputes about what was agreed are resolved based on whoever has better recall or more leverage - usually the client. Written contracts create a shared record of what was agreed, protect your intellectual property, ensure you get paid, and limit your liability if something goes wrong. They also make you look more professional, which tends to attract better clients and command higher rates.

Document 1: The NDA (Non-Disclosure Agreement)

Sign an NDA before any substantive conversation about the project begins. Clients will often share confidential information - unreleased products, internal financials, customer data, or proprietary systems - during the briefing process. An NDA ensures you are legally bound to keep that information confidential, which protects the client and demonstrates that you take confidentiality seriously.

• When to use it: Before the first detailed project briefing, before receiving any confidential files, and before any discussion that involves the client's unpublished products, systems, or strategies.
• What it should include: Both parties' names, a definition of what is confidential, your obligation not to disclose or misuse it, exclusions (publicly available information), the duration of confidentiality, and governing law.
• Mutual or one-way: For most freelance engagements, a one-way NDA is appropriate (the client discloses to you). A mutual NDA is better if you are also sharing your own methodologies or proprietary tools with the client.
• Common mistake: Waiting until the project is underway. An NDA only covers information disclosed after it is signed.

Document 2: The Proposal or Statement of Work

A proposal sets out what you will deliver, when, and for how much. A statement of work (SOW) is more detailed and typically used for longer or more complex engagements. For most freelance projects, a detailed proposal that doubles as an SOW is sufficient. This is the document that prevents scope creep - the single most common source of freelance disputes.

• Project scope: A precise description of what is included - and what is not. 'Three rounds of revisions' is specific. 'Revisions as needed' is a blank cheque.
• Deliverables: Each output you will produce, with format and acceptance criteria where relevant.
• Timeline: Key milestones and the final delivery date. Include what happens if the client delays providing materials or feedback.
• Payment terms: Total fee, payment schedule (deposit, milestone payments, final payment), accepted payment methods, and what constitutes late payment.
• Intellectual property: Who owns the work. The default in most countries is that the creator retains copyright until explicitly assigned. If the client wants to own the work outright, this must be stated and is typically priced higher.
• Revision policy: How many rounds of revisions are included, what constitutes a revision versus new work, and the rate for additional work.
• Termination clause: What happens if the project is cancelled mid-way, including who keeps any deposit paid.

Document 3: The Invoice

An invoice is not just a payment request - it is a legal document. A properly structured invoice creates a written record of the debt, specifies the payment due date, and is the document you would use in any payment dispute or legal action. Issue invoices promptly: research consistently shows that invoices sent within 24 hours of project completion are paid faster than those sent days later.

• Invoice number: Use sequential numbers (INV-001, INV-002). Required for tax and accounting purposes in most countries.
• Issue date and due date: State both. 'Net 30' means payment is due 30 days after the invoice date.
• Your details: Your full name or business name, address, and email.
• Client details: Client's business name and address.
• Line items: A description of each service delivered, quantity, unit price, and line total.
• Tax: If you are registered for VAT, GST, or sales tax, include the tax registration number and the tax amount separately.
• Payment instructions: Your bank details, PayPal address, or payment link. Without this, even willing clients cannot pay you.
• Late payment clause: State the interest rate that applies to overdue invoices. This is enforceable in most jurisdictions and acts as a deterrent to slow payment.

What order to send documents

1. NDA - before any detailed briefing or sharing of confidential client materials.
2. Proposal / Statement of Work - after the briefing, once you understand the project scope. Get this signed before any work begins.
3. Deposit invoice - issue before starting work. A 25-50% deposit is standard for most freelance projects and filters out clients who are not serious.
4. Progress invoices - for longer projects, issue at agreed milestones.
5. Final invoice - on delivery of the final deliverable. Do not deliver the final files until the final invoice is paid, unless your contract specifically allows for it.

Common freelance contract mistakes

• Starting work before a contract is signed - once you have started, your negotiating position is weaker and it is harder to walk away if terms are not agreed.
• Not specifying who owns the intellectual property - without an explicit clause, ownership depends on jurisdiction. In the UK, copyright generally stays with the creator; in the US the work-for-hire doctrine can sometimes assign it to the client. Be explicit.
• Vague revision policies - 'unlimited revisions' or 'until you are happy' gives clients no incentive to make decisions and removes any boundary on your time.
• Forgetting to invoice for out-of-pocket expenses - travel, software licences, stock imagery, and third-party services should be billed separately unless your proposal explicitly includes them in the fixed fee.
• Not following up on overdue invoices - sending one reminder and then giving up is common. A structured follow-up process (reminder at due date, 7 days over, 14 days over, formal notice at 30 days over) significantly improves collection rates.
