Website Development Agreement Format
Most website disputes come down to one question: was that included in the price? This development agreement answers it in advance with clear deliverables, milestones, and payment terms.

When and how to use this letter
Use this agreement before any website build begins, whether it is a simple brochure site or a full e-commerce project. Sign it after the proposal is accepted and before design work starts.
Exchange signed PDFs by email, and attach the approved proposal or sitemap as an annexure so the agreed scope is part of the signed record. Version the annexure if the scope changes mid-project.
Describe the scope in deliverables, not adjectives. A modern, fast website means nothing enforceable; an 8-page site with contact form and online menu does. List pages, features, and integrations explicitly, and name who provides the content and images.
Include what to avoid: avoid starting without content deadlines for the client, since waiting on client content is the top cause of web project delays. Avoid unlimited revisions, which turn fixed-price projects into losses. Never hand over admin credentials or domain control before final payment is received.
What happens next: the client delivers content, the developer builds to the milestones, and each stage is approved in writing before the next payment. A practical tip: define done before you start. Write one sentence for each milestone stating what counts as complete, so approval is a quick yes rather than a new negotiation.
