How to Write a Web Development Contract

Web projects are scope-creep magnets. "Can we just add a blog?" "Can it also do bookings?" Without a contract that pins down the build, you end up doing twice the work for the same fee. A clear web development contract protects your scope, your timeline, and your payment.

What makes web projects risky

Three things: scope is easy to expand ("it's just a button"), payment often comes at the end (after all the work), and ownership of code, content, and accounts gets murky. A good contract addresses all three before the project starts.

Clauses to include

1. Scope. Specific pages, features, and functionality. Reference a scope of work for the detail.
2. Milestones and payments. Tie payments to phases — deposit, design approval, development, launch.
3. Revisions. How many rounds are included per phase.
4. Client responsibilities. Content, images, access, and timely feedback — projects stall when the client doesn't deliver these.
5. Intellectual property. Who owns the code and design, and when it transfers (usually on final payment).
6. Third-party costs. Hosting, domains, plugins, stock assets — who pays.
7. Launch and acceptance. What "done" means and how it's signed off.
8. Maintenance. Whether ongoing support is included or billed separately (a good upsell — see retainers).

The key to avoiding scope creep

Define the build specifically and require new requests to go through a change process at an agreed rate. When a client asks for an extra feature, you don't say no — you say "happy to; that's an add-on, here's the cost." A milestone payment schedule also protects you: you're never more than one phase ahead of being paid.

Don't forget IP and client responsibilities

State that you own the work until final payment, then it transfers. And spell out what the client must provide and by when — most missed deadlines are caused by clients who didn't deliver content, not by developers.
