What should a web development proposal include?

A plain-language summary of the problem, the features in scope and out of scope, the tech stack and hosting, milestones with acceptance criteria, a pricing model, what you need from the client, and terms covering payment, changes, bugs and code ownership.

Should I charge a fixed price or hourly for web development?

Fixed price suits small, well-defined jobs. Milestone pricing suits larger builds with a clear specification. Time and materials with a cap suits projects where requirements will change. You can offer two of these and let the client choose.

How technical should a web development proposal be?

Technical enough for a developer on the client's side to check your choices: stack, hosting, environments, testing and security basics. Keep the explanation in plain language and put deep detail in a separate specification.

How do I handle scope changes during a development project?

Use a change request process. Describe the change, estimate the time and cost, and start only after the client approves it in writing. Keep a simple log so both sides can see what was added.

What is a paid discovery phase?

A short, paid first step where you work with the client to turn a rough idea into a written specification, wireframes and a firm quote. It reduces risk for both sides on projects that aren't yet well defined.

Can I use this template for Upwork or Freelancer.com bids?

Proposal template

Web development proposal template

Updated 23 October 2026

Quick answer

A web development proposal should explain the problem the software solves, list the features in scope (and what's left for later), name the tech stack and hosting, and break the build into milestones with acceptance criteria. It should also offer a pricing model (fixed price, milestones or time and materials) and say who owns the code. Copy the template below and replace each [bracket] with the project's details.

The web development proposal template

Web development proposals tend to fail in one of two ways. Some are so vague the client can't compare them with anyone else's. Others are so technical that the person holding the budget can't follow them. The ones that win explain the build in plain language first, then add the technical detail where it matters: stack, environments, integrations and how each milestone will be tested.

Use this template for custom web apps, client portals, booking systems, integrations and API work, and feature work on an existing codebase. If the project is mainly a marketing website, the web design proposal template is a better fit.

The filled-in example further down uses a fictional client. Its names, prices and dates are illustrations, so use your own numbers.

Web development proposal: [project name]

Prepared for: [Client name], [Company]
Prepared by: [Your name], [portfolio or code samples link]
Date: [date]
Valid until: [date]

1. Summary
[Company] needs [what the software does, in one sentence] so that [who uses it] can [the outcome]. Today this is handled by [the current process: spreadsheets, an old system, manual emails], which [the cost or problem it causes].

2. Goals
- [Goal 1, e.g. customers can place and track orders without emailing the team]
- [Goal 2, e.g. staff manage every order from one dashboard]
- [Goal 3, e.g. pages load quickly on mobile connections]

3. Scope of work
Users and roles: [e.g. customer, staff, admin]
Features in this phase:
1. [As a (user), I can (action) so that (benefit)]
2. [Feature]
3. [Feature]
4. [Feature]
Integrations: [payment provider, email service, CRM, accounting software, existing API]
Data migration: [what moves from the old system, or "none"]
Not in this phase: [features deliberately left for later]

4. Technical approach
Stack: [framework and language], [database], hosted on [hosting provider].
Why: [one or two plain reasons, e.g. well supported, easy to hire for later, low hosting costs, fits your existing systems].
Environments: local development, a staging site for your reviews, and production.
Quality: code in a Git repository you own, automated tests for [critical flows], and a review before each release.
Security: HTTPS, hashed passwords, role-based access, input validation, regular dependency updates and daily backups with a tested restore.
Running costs paid by you: [hosting, domain, third-party services], estimated at [amount] per month.

5. Milestones and timeline
Milestone 1, discovery and specification: [X days]. Deliverable: written specification and wireframes.
Milestone 2, [core features]: [X weeks]. Accepted when: [criteria].
Milestone 3, [remaining features and integrations]: [X weeks]. Accepted when: [criteria].
Milestone 4, testing, data migration and launch: [X weeks]. Accepted when the application is live on your domain and the agreed test checklist passes.
Each milestone is on staging for [5] working days of testing before it counts as accepted.

6. Pricing options
Option A, fixed price for the scope above: [price], invoiced per milestone.
Option B, time and materials: [hourly or day rate], estimated at [range], with no more than [cap] spent without your written approval.
Option C, first version only: milestones 1 and 2 for [price], so you can test with real users before committing to the rest.
Maintenance after launch: [price] per month for updates, monitoring, backups and up to [X] hours of fixes or small changes.

7. What I need from you
- A product owner who can answer questions and test each milestone
- Access to existing systems, APIs, hosting and any current code
- Brand assets, copy and sample data by [date]
- Third-party service accounts set up in your company's name

8. Terms
Payment: [deposit] to start, then each milestone invoiced on acceptance, due within [X] days.
Changes: new features, or changes to accepted work, are estimated in writing and start only after you approve them.
Bugs: defects in agreed features reported within [30] days of launch are fixed at no charge.
Ownership: once paid in full, you own the custom code written for this project. Open-source libraries keep their own licences.
Confidentiality: I'll keep your data and business information confidential, and I'm happy to sign an NDA.
Handover: repository access, deployment notes, environment settings and a short technical document.

9. Next steps
1. Choose an option, or send me your questions.
2. I'll send the agreement and the first invoice.
3. We hold a kick-off call, and I set up the repository and staging site within [X] working days.

What to include in a web development proposal

Write for two readers: the person who signs off the budget and the person who will check your technical choices. Put a plain-language summary first and the technical detail second.

The problem and the users: who will use the software and what they need to get done.
Features in scope, written as user stories or a numbered list, plus a clear "not in this phase" list.
The tech stack and why you chose it: framework, database, hosting and any third-party services such as payments, email sending or maps.
Running costs the client will pay directly, such as hosting and third-party subscriptions, so nothing surprises them later.
Environments: local development, a staging site for reviews and production.
Milestones, each with acceptance criteria the client can test.
Testing, security basics, how bugs are handled after launch, and who owns the code and the repository.

Fixed price, milestones or time and materials?

Fixed price works when the scope is small and well defined. Clients like the certainty, but you carry the risk if your estimate is wrong, so build in a buffer and a clear change request process.

Milestone pricing splits a larger build into paid stages, each with its own deliverable and acceptance criteria. The client pays for working software, and you get paid as you go rather than at the end.

Time and materials (an hourly or daily rate with an estimate and an agreed cap) suits projects where requirements will change, such as a first version of a product, or work on an unfamiliar older codebase. Monthly maintenance retainers cover updates, monitoring and small fixes after launch.

Number of user roles and permission levels.
Integrations with third-party APIs, payment providers or the client's existing systems.
Data migration from an old system.
Admin dashboards, reporting and exports.
Security, compliance or performance requirements.
The state of the existing codebase, if you're not starting fresh.
Ongoing hosting, monitoring and maintenance.

When to sell a paid discovery phase first

If the brief is a paragraph and a wish list, don't guess a fixed price for the whole build. Offer a short, paid discovery phase instead: a workshop or two, a written specification, wireframes or a clickable prototype, an outline of the architecture, and a firm quote for the build.

The client gets a document they own even if they don't continue with you, and you avoid quoting blind. If you want to make the decision easier, credit part of the discovery fee against the build.

Acceptance criteria and change requests

Acceptance criteria turn "it doesn't feel finished" into a checklist. For each milestone, list what the client will test, for example: "A customer can reset their password from the login page and receives the reset email."

Give the client a fixed testing window for each milestone, such as five working days, after which it counts as accepted. Anything new goes through a change request: you describe it, estimate it and start only after written approval.

Name the security basics you'll cover: HTTPS everywhere, hashed passwords, input validation, role-based access, regular dependency updates and backups with a tested restore.
Say you'll check the build against common web application risks, such as those listed in the OWASP Top 10.
Define what counts as a bug (an agreed feature not working as specified) versus a change (anything new or different).

Code ownership, hosting and handover

Clients worry about being locked in. Answer it in the proposal: the code lives in a Git repository the client owns or can access, hosting and third-party accounts are in the client's company name, and you hand over documentation at the end.

Ownership of code depends on your agreement and local law, so write it down. A common arrangement is that the client owns the custom code once paid in full, while open-source libraries keep their own licences. For high-value projects, ask a lawyer to check the wording.

Short web development bid for Freelancer.com or Upwork

Marketplace clients read short bids, not documents. Send this first, and the full proposal once they reply.

Hi [client name],

You need [the system or feature] built so that [users] can [action] without [the current manual workaround], and it has to work with [their existing tool or API].

Here's how I'd approach it:
1. Confirm the user flows and edge cases with you, then share a short written specification
2. Build in milestones on a staging site you can test, starting with [the most important feature]
3. Test, migrate your existing data and launch, with the code in a repository you own

[proof: a similar build, with a link or a one-line description of what it does]

Quick question: do you already have API access to [integration or existing system], or will we need to set that up?

I can deliver the first working milestone in [timeline], and the full scope for [price].

Mistakes that lose web development clients

Quoting a fixed price from a two-line brief instead of offering a paid discovery phase first.
Leaving out acceptance criteria, so "done" becomes a matter of opinion.
Choosing a stack because it's your favourite rather than because it suits the client's budget, hosting and future hiring.
Forgetting third-party running costs such as hosting, email sending, maps and payment fees, which then surprise the client after launch.
Not saying where the code lives or when the client gets repository access.
Having no change request process, so every new idea quietly lands inside the fixed price.
