Short answer: yes, but only the parts that protect you
A web design proposal should include contract terms, not a separate 10-page legal document glued to the back. For solo designers and small studios, the proposal is the contract in practice — the client reads the scope, sees the price, sees the terms underneath, and signs once. Splitting the proposal and the contract into two separate documents usually means the client reads one and skims the other, which is exactly the gap where disputes start.
This only works if the terms section is short, written in plain English, and covers the five things that actually cause arguments: payment, scope boundaries, timeline dependencies, ownership, and cancellation. Everything else — insurance clauses, indemnification language, jurisdiction boilerplate — belongs in a standalone agreement your lawyer reviews once and you reuse for every client, not in the proposal itself.
Why bundling terms into the proposal works better for freelancers
Separate contracts have a real cost: a second document means a second round of "let me look this over," a second place for the client to stall, and a second thing you have to chase before work starts. Every extra step between "they like the proposal" and "they pay the deposit" is a point where a client cools off or a competitor gets a call back.
When the terms live inside the proposal, signing the proposal is signing the agreement. You lose nothing in protection as long as the terms section actually says something — most proposal templates either skip it entirely or bury one vague line like "standard terms apply," which protects no one.
What the terms section needs to say
Keep it to five short blocks. Each one should answer a question a client would actually ask if a project went sideways.
1. Payment schedule and what happens if it slips. State the deposit, the milestone payments, and what happens if an invoice goes unpaid — work pauses, a late fee applies, whichever is true for you.
2. What is and isn't included. Point back to the scope section above it. State plainly that anything not listed is a change request, priced separately.
3. What you need from the client, and by when. Content, images, logins, feedback turnaround. If the client doesn't deliver, the timeline moves — say so here, not just in an email later.
4. Who owns what, and when. Final files and IP transfer to the client on final payment, not on project start. Say this directly; it's the single most common point of confusion in design contracts.
5. How either side exits. A kill fee or a simple rule like "deposit is non-refundable once design work begins" protects the hours you've already spent if a client disappears mid-project.
A sample terms section you can adapt
This is the kind of language that fits directly under the price block of a proposal, written for a $6,500 small-business redesign:
Terms
A 50% deposit ($3,250) is due before work begins; the remaining 50% is due at launch. Work pauses if an invoice is unpaid for more than 7 days.
This proposal covers the pages and features listed under "Scope" above. Additional pages, revisions beyond the two rounds included, or new features are quoted separately and added by written change order.
The client will supply final copy, images, and any existing brand assets within 5 business days of signing. Timeline estimates above assume this deadline is met; late delivery of content shifts the launch date accordingly.
Source files and full ownership of the completed site transfer to the client upon receipt of final payment. Until then, all design work remains the property of [Your Studio Name].
Either party may cancel with written notice. The deposit is non-refundable once design work has started; the client is billed for any completed milestones not yet invoiced.
Signed and dated below, this proposal becomes the working agreement for the project.
Five short paragraphs, no legal jargon, and a client can read the whole thing in under a minute. That's the bar: if your terms section takes longer to read than the scope section above it, cut it down.
When you still need a separate contract
Bundle terms into the proposal for most web design work. Reach for a standalone, lawyer-reviewed agreement instead when:
- The project is large enough that a client's legal or procurement team is involved (common past roughly $15–20k).
- You're working with a client in a regulated industry (healthcare, finance, legal) where their own compliance team requires specific language.
- You're taking on ongoing retainer work rather than a single project — recurring engagements need renewal and termination terms a one-off proposal doesn't.
- A client specifically asks for a separate signed agreement. Give it to them; it costs you nothing and removes their objection.
In every other case — brochure sites, redesigns, landing pages, small e-commerce builds — a clear terms section inside the proposal is enough, and it's what most solo designers and small studios already use without realizing it has a name.
Checklist: does your proposal's terms section hold up?
- Payment schedule is specific (amounts and dates, not "payment due upon completion")
- Scope boundaries are restated, with a clear path for anything outside them
- Client responsibilities and deadlines are named, with the effect on timeline spelled out
- Ownership transfer is tied to final payment, stated in one direct sentence
- Cancellation terms protect your deposit and already-completed milestones
- The whole section reads in under a minute
- You've asked a past client (or a friend) to read it cold and tell you what's unclear
If more than one of these is missing, the gap isn't your scope or your price — it's the quiet assumption that "we'll sort it out if something goes wrong." Terms exist so you don't have to sort it out in the middle of a project.
Where this fits in the proposal itself
Order matters. Put the terms section after the price block and before the signature line — not buried in an appendix, not as a separate attached PDF the client has to open. The sequence a client should see is: what you're building, what it costs, what happens on each side if something changes, then a place to sign. That order mirrors how the decision actually gets made.
If you're rebuilding your proposal template from scratch, The Web Design Proposal Kit includes a terms section written exactly this way, along with the scope, pricing, and timeline sections it needs to sit next to — built so you can send a complete, signable proposal without assembling it from five different documents.
