15 kinds of contracts you'll actually run into

Most lists like this cover the contracts a law firm handles. Here are the ones an actual freelancer or small business sends.

"Types of contracts" lists tend to read like a law school syllabus. This one is filtered down to what shows up in an actual inbox if you run a small business or freelance.

  • Mutual NDA - both sides share confidential information and both are bound not to disclose it.
  • One-way NDA - only one side is disclosing anything; only that side's information is protected.
  • Consulting agreement - ongoing advisory work, usually billed by time rather than by deliverable.
  • Freelance / services contract - a defined scope of work for a fee, the most common document a freelancer sends.
  • Statement of work - a specific project attached to a broader master agreement, common when the same client returns repeatedly.
  • Independent contractor agreement - establishes that the relationship is a contractor one, not employment, which matters for tax and liability.
  • Employment offer letter - the terms of a job before the full employment contract, often the only document a small company sends.
  • Employment contract - the fuller version, covering role, compensation, benefits, and termination.
  • Licensing agreement - permission to use something you own - software, a design, a brand - under specific conditions.
  • Purchase agreement - a one-time sale of goods, equipment, or a business itself.
  • Lease or rental agreement - use of property or equipment for a period, in exchange for payment.
  • Partnership agreement - how two or more people share ownership, profit, and decisions in a joint venture.
  • Non-compete - restricts someone from working with competitors for a period after the relationship ends, and is unenforceable in some places entirely.
  • Vendor or supplier agreement - ongoing terms with someone who supplies goods or services into your business.
  • Amendment or addendum - a change to a contract already signed, rather than a new one from scratch.

The one thing they all share

Different subject matter, different clauses, same underlying requirement: an offer, an acceptance, something of value moving both ways, and evidence of who agreed to it. The contract type changes what is being promised. It does not change what makes the promise stick.

What actually makes a document legally bindingNot the signature itself, and not the font size of the fine print. Here is what a court is actually checking for once a contract already exists.Does an electronic signature work outside your own country?Sending a contract abroad does not usually change whether the signature holds up - but there are real exceptions worth knowing before assuming it is fine.Do you need a signing platform, or just a PDF and an email?Sometimes the honest answer is no. Here is how to tell which situation you are actually in.What is actually in a sealed PDFA walk through the finished file: the stamped fields, the certificate page, the detached PKCS#7 signature, and how to verify it yourself with openssl.Addendum or amendment: what's the differenceBoth change a contract after it has been signed. They are not interchangeable, and using the wrong one can create a document that contradicts itself.What to put in a freelance contractThe clauses that actually prevent a dispute later, not a wall of boilerplate nobody reads.Are electronic signatures admissible in court?Yes - and they usually hold up better than paper. But admissibility depends on the evidence behind the signature, not the signature itself.The six things a contract actually needsA contract is not defined by having a signature line at the bottom. It is defined by six things being true, and a document can fail every one of them while still looking exactly like a contract.Radio button or checkbox: how to pick the right fieldOne is for choosing exactly one option. The other is for anything else. Getting it backwards on a contract quietly creates a document that can be filled in two contradictory ways.What DocuSign actually costs, and why we stopped paying itWe worked out what it costs to send one document for signature. It is a fraction of a cent. Here is what we were paying instead.Digital signature vs electronic signature: what's actually differentThe two terms get used as if they mean the same thing. They don't, and the gap between them is where a lot of vendors make their money.Is an electronic signature legally binding?Short answer: almost always, and it has been for twenty years. The longer answer is about evidence, not about the signature itself.
