The five contracts every freelancer should have

Contracts & e-sign · 4 min read

You don't need a filing cabinet of legal documents. These five contracts — service agreement, NDA, IP transfer, retainer, and SOW — cover almost every freelance situation.

Plenty of freelancers either over-engineer their paperwork — chasing a bespoke contract for every conceivable situation — or skip it entirely and work on a handshake and a hopeful email. Both are mistakes. The truth sits in the middle: there's a small, fixed set of contracts that, between them, cover almost everything you'll encounter as an independent professional. Master these five, keep them ready as templates, and you'll always have the right document on hand without drafting from scratch or leaving yourself exposed. Here's what each one is for and what it should protect.

1. The service agreement

This is your workhorse — the default contract for project-based work, and the one you'll use most. A good service agreement spells out the scope of what you'll deliver, the fee and payment schedule, the timeline, and the terms that govern the relationship: revisions, what counts as out-of-scope, how either side can end the engagement, and who's liable for what. It exists to make sure you and the client share the same picture of the deal before any work begins, and to give you something concrete to point to if that picture later blurs. If you only ever set up one template properly, make it this one.

2. The NDA

A non-disclosure agreement comes into play when a client needs to share confidential information with you — product plans, customer data, unreleased designs — before or during a project. It commits both sides to keeping defined information private. Clients in sensitive industries will often ask you to sign theirs, but having your own ready signals professionalism and lets you propose one when you're the party sharing something confidential. Keep it short and mutual where you can; a bloated NDA is harder to get signed and rarely more protective.

3. The IP transfer (assignment)

Here's a trap that catches new freelancers: by default, in many places, the creator of a work owns it — which means without an explicit transfer, your client may not legally own the logo, code, or copy you delivered, even after paying for it. An IP transfer (or assignment) clause fixes this by formally handing ownership of the deliverables to the client. The key detail:

Tie the transfer of intellectual property to full payment. Until the invoice is paid, the work stays yours — which gives you real leverage if a client goes quiet.

That single condition — ownership transfers on payment, not on delivery — protects you more than almost any other clause in your contracts.

4. The retainer

When work shifts from one-off projects to an ongoing relationship, a retainer is the contract you want. It covers recurring engagements — a set number of hours or a defined scope of work each month for a fixed fee — and it's the closest a freelancer gets to predictable income. A solid retainer defines what's included each period, what happens to unused hours, how either side gives notice, and how rates may change over time. Retainers pair naturally with recurring invoicing: once the contract sets the cadence, your invoicing can send on the same schedule automatically.

5. The statement of work (SOW)

A statement of work is the specialist of the group. Rather than standing alone, it usually sits underneath a master service agreement and pins down the specifics of one particular engagement: precise deliverables, milestones, dates, and the price for that body of work. The pattern is powerful for repeat clients — you sign the master agreement once, then issue a fresh, lightweight SOW for each new project without renegotiating the whole relationship every time. It keeps scope crisp and disputes rare.

Keep them ready, not theoretical

Knowing these five exist isn't enough — the value is in having them ready to send in minutes. That's why Kliently's contracts & e-sign module ships with exactly these five as starter templates: service agreement, NDA, IP transfer, retainer, and SOW. Variables auto-fill the client and project details so you're reviewing a finished draft, not building one. From there, our guide to building a contract template library shows how to turn these into a system you'll genuinely use.

Five contracts. Each with a clear job. Together they cover the proposal-won project, the confidential brief, the handover of ownership, the ongoing relationship, and the repeat engagement — which is to say, almost everything a freelance career throws at you. Set them up once and you'll never again stare at a blank page wondering how to paper a deal.
