Website Design and Development Proposal

Who this template is for

Web designers, developers and small studios quoting a new marketing website or a rebuild of an existing one. The sample uses Webflow with five core page types and a reusable case-study template, but the structure works for any CMS. It is not built for online shops, member portals or custom integrations, which the template lists as out of scope.

What each section covers

Introduction and Priorities

Names the site’s primary action, the platform and the target launch, then frames the work around what visitors need: understanding the offer, evaluating the work and starting a conversation.

Design Direction

One visual language across pages, mobile designed alongside desktop, two consolidated review rounds, and approval of key layouts before development begins.

Sitemap and Services

The page types in scope, what the client supplies (approved copy, brand assets, permissions), an included delivery checklist with 30 days of in-scope defect support, and a clear out-of-scope list.

Your Team and Client Reference

Project, design and development leads plus the client reviewer, and one approved testimonial. Use only a reference you have permission to share.

Timeline, Pricing and Next Steps

Four milestones from brief to launch, each with a gate and a feedback turnaround dependency, then a one-time project fee, a milestone billing schedule and kickoff preparation.

How to price a website project

The template uses a fixed project fee split into three line items: content planning and responsive design, development and CMS setup, and launch checks and handover. Payment is staged across project booking, design approval and launch handover, so you are paid as each gate is passed rather than all at the end.

Keep running costs out of the project fee. Hosting, domains, platform subscriptions, paid fonts and asset licences are listed as paid separately, and ongoing maintenance is quoted as its own service. If the client wants copywriting or more pages, add them as priced items rather than absorbing them.

Before you send it

Confirm who writes the copy

Full copywriting is out of scope. If the client is supplying copy, set a date for it, because missing content holds up the build stage.

Fix the page count

List every page type in the sitemap. Additional pages are out of scope, so the client should see exactly what the fee covers.

Check the feedback dependency

The timeline assumes client feedback within three business days. If that is unrealistic for their team, adjust the timeline now rather than after a missed launch date.

Line up the dates

Make sure the offer expiry comes before the proposed start date and that the target launch matches the milestone plan.
