What Should a Web Developer Contract Include?

A web development contract should cover the parties, the scope and deliverables, explicit exclusions, the timeline with both sides' dependencies, the payment schedule, IP and ownership transfer on final payment, revisions, change requests, confidentiality, a warranty period, termination, support after launch, and how disputes get handled. Most disputes in web projects trace back to one of those being absent rather than badly worded.

One thing up front: I'm a developer, not a lawyer. What follows describes what these clauses do and why they matter in practice, based on how web projects actually go wrong. It isn't legal advice, and it isn't a substitute for it. For anything significant — a large budget, sensitive data, or a client who worries you — pay a lawyer to look at the contract. That's a small cost against the thing it protects.

You've compared the quotes and picked someone. This is the last checkpoint before work starts. If you want the earlier stage, how to compare web developer quotes is the pillar.

The clauses, and what each one is for

1. Parties

The legal entities, not the trading names. If you're contracting with a company, the company's registered name and number; if with an individual, their name. This sounds like paperwork until you need to know who you actually have an agreement with.

2. Scope and deliverables

What's being built, described specifically enough that a third party could tell whether it was delivered. This is the clause everything else hangs off — a warranty on undefined work means nothing, and neither does a termination clause that can't establish what was completed.

3. Exclusions

What's explicitly not included. The most-skipped clause and one of the most valuable, because it converts the assumptions in your head into a written statement you can check now rather than discover later.

4. Timeline and dependencies

Milestones with dates, and what you have to supply by when. A contract that only binds the developer's dates will be missed on your content, and then there's an argument about it. Naming both sides' obligations is the single cheapest way to prevent that.

5. Payment schedule

Amounts tied to milestones or dates, when invoices are issued, and payment terms. Roughly a third up front with the remainder against milestones is standard. Check specifically whether final payment falls due before or after you've seen the finished work, because that ordering is where leverage lives.

6. IP and ownership transfer

The clause that costs the most when it's missing. It should state that on final payment you own the code, the domain registered in your name, the hosting account and the design files.

Worth understanding why this needs saying explicitly: in many jurisdictions, where a contract is silent, copyright in commissioned work stays with the person who created it even though the client paid for it. That surprises people, and it's the mechanism behind a lot of "but I paid for this" disputes. Whether it applies to you depends on where each party sits and what the contract says — which is precisely the kind of question to put to a lawyer rather than to a developer's blog.

Also specify any third-party components: licensed themes, stock images, paid plugins. You need to know what transfers and what's licensed to whom. Taking over a website from another developer is what this clause exists to prevent.

7. Revisions

How many rounds, at which stages, and what constitutes one round. "Unlimited" belongs in marketing copy, not in a contract, because it can't be enforced by either side.

8. Change requests

The process and the rate. Written request, written quote, written approval, then work. This clause is what stops a good idea in a phone call becoming an invoice nobody expected.

9. Confidentiality

Mutual, ideally. They'll see your business data, your customer information, and possibly your financials. You may see their methods. If the project involves personal data, this clause needs to sit alongside your actual data-protection obligations rather than substitute for them.

10. Warranty period

How long after launch defects in their own work get fixed at no charge, and what counts as a defect rather than a change. Thirty days is common and reasonable. The distinction that matters: fixing what's broken versus changing what works as specified.

11. Termination

How either side ends the agreement, what notice is required, what's owed for work completed, and — critically — what you receive on termination. Does partial work transfer, and in what form? This is the clause you'll want when the relationship is going badly, which is exactly when it's too late to negotiate.

12. Support after launch

Whether there's an ongoing arrangement, what it covers, what it costs and how it's terminated. Often a separate agreement, and that's fine — but it should exist before you need it. NZ maintenance retainers run $50–$200/month for a site; applications considerably more.

13. Dispute handling and governing law

Which country's law applies and how disagreements are resolved — negotiation, then mediation, before anything formal. This matters more in cross-border work, where the practical answer is usually that litigation isn't worth it for either party, which makes the earlier clauses your real protection. Hiring a remote developer covers the rest of that setup.

What a missing clause actually costs

Do you need a lawyer?

For a small, straightforward website with a developer who has a clear standard agreement, most small businesses reasonably proceed on a well-written contract without paying for review. That's a risk judgement, not a recommendation.

Get a lawyer when the budget is significant relative to your business, when the project handles personal, health or financial data, when you're contracting across borders on something substantial, or when anything in the contract seems designed to be difficult to understand. A couple of hours of legal time is cheap next to the cases above.

What I'd avoid is downloading a template and treating it as done. A contract you haven't read and don't understand protects you roughly as well as no contract, and it can be worse, because it creates the belief that the question is settled.

Frequently asked questions

What should a web development contract include?

The parties as legal entities, scope and deliverables, explicit exclusions, a timeline naming both sides' dependencies, the payment schedule, IP and ownership transferring on final payment, revision rounds, a change-request process and rate, confidentiality, a warranty period on defects, termination terms including what you receive, post-launch support, and governing law. This describes what the clauses do in practice; it isn't legal advice.

Do I need a contract for a small website project?

Yes, though it can be short. Even a single page covering scope, price, timeline, ownership and payment protects both sides and prevents the most common disputes. The size of the project changes how much detail is warranted, not whether an agreement should exist — and a developer who resists writing one is telling you something useful.

Who owns the website after the contract ends?

Whatever the contract says — which is why it must say something. A well-drafted clause transfers the code, the domain registered in your name, the hosting account and the design files to you on final payment, and names any third-party licensed components separately. Where a contract is silent, ownership can default in ways that surprise clients, and the specifics depend on jurisdiction. Worth a lawyer's eye if the project is significant.

What is a reasonable warranty period for a website?

Thirty days of free fixes on defects in the developer's own work is common and reasonable, with some providers offering longer. The important part isn't the length but the definition: the contract should distinguish fixing something broken from changing something that works as specified, because that boundary is where warranty disputes actually happen.

Can I use a web development contract template?

You can, but read every clause and make sure it matches your project and your jurisdiction — a template you haven't understood offers little real protection and can create false confidence. For a small straightforward site that's often an acceptable risk. For significant budgets, personal or financial data, or cross-border work, pay for a lawyer to review it.

Where to start

Take the contract you've been sent and check it against the thirteen clauses above. Anything missing is a question to ask before signing, and asking it costs nothing — a good developer will answer it in a sentence and probably add the clause.
