Yes, AI can draft an interior design contract in plain English, especially the design-fee, revision, deposit and procurement clauses, if you give it your own stages and rules. It cannot tell you what is enforceable where you work, so a solicitor must check fees, deposits, cancellation, liability and the way you buy for clients.
An interior design contract carries risks that a builder's contract does not. You sell judgement and time rather than materials, you often buy furniture and finishes on the client's behalf, and the client's taste is a moving target. The clauses that protect you are about fees, revisions and who owns the purchasing risk. Get those three right in plain words and most fee arguments never start. Every figure below is illustrative, and none of it is legal advice.
Decide how you charge before you draft anything
AI cannot choose your fee model, and a contract written around the wrong one fails quickly. Pick one for each project and write down the logic in plain notes:
- Fixed fee per stage: concept, developed design, procurement and installation each priced. Suits projects with clear scope.
- Hourly with a cap: a rate and an estimate, with a stop-and-discuss point at the cap. Suits uncertain scope.
- Percentage of spend: a fee based on purchases made through you. It needs clear rules on what counts as spend, and it may be restricted or require disclosure in some places.
- Mark-up on purchases: you buy at trade price and sell at a stated mark-up. Requires disclosure and a decision on whether you act as principal or agent.
- Hybrid: a fixed design fee plus a procurement fee.
The contract has to match how you actually earn money, because a clause that says "fees are fixed" will not help when your practice is to bill hourly. Write the notes in your own words first; that is the raw material the prompts use.
Design-fee clauses drafted with AI
Here is a prompt for a made-up studio that charges a fixed fee per stage with a deposit up front. Treat the figures as illustrative.
You are helping a small interior design studio write contract clauses in plain English
(short sentences, numbered, no legal Latin).
Write ONLY the "Design fees and payment" section.
Our rules:
- Three stages: Concept ($2,400), Developed design ($3,600), Procurement and
installation management ($4,000). Total $10,000 for this template; use placeholders.
- A deposit of [X]% of the total is due on signing and is credited against the final
stage.
- Each stage is invoiced when it starts, due within 7 days.
- Work on the next stage starts only when the previous stage invoice is paid.
- Expenses (travel, samples, printing) are charged at cost with receipts, over
[amount] per month only with prior approval.
- Fees do not include the cost of furniture, finishes or trades.
After the clauses, list "Questions for my solicitor" for any point where local law may
limit deposits, payment timing or my right to pause work.What the draft looks like, and what to fix
An illustrative reply begins: "3.1 Our design fee is split into three stages, shown in the table below. 3.2 You pay a deposit of [X]% when you sign. We credit it against the final stage invoice. 3.3 We invoice each stage when it starts. You pay within 7 days. 3.4 We begin the next stage once the previous invoice is paid." Three fixes are usual. First, "we credit it against the final stage" should say what happens to the deposit if the project stops after Stage 1: refundable, partly refundable or earned. Second, "7 days" should be working or calendar days, consistently. Third, the draft rarely says what happens to the fee if the client halts a project mid-stage. That is a prompt of its own, and a question for the solicitor.

Buy nowRevisions: define the round before you count it
Revision disputes happen because "a round" is never defined. A client who sends forty small comments over three days believes that is one round, while the designer thinks it is six. The clause needs three things: a definition, an allowance and a price for more.
Write a "Revisions" clause. Mechanism:
- A revision round means one consolidated set of written comments from the client on
one stage deliverable, sent within 7 days of the deliverable.
- Concept stage includes 2 rounds. Developed design includes 2 rounds.
- Comments that change the brief (new room, new budget, changed style direction after
approval) are a change of scope, not a revision, and are handled under "Changes".
- Extra rounds are charged at $[rate] per hour with an estimate given first.
- Comments sent piecemeal will be grouped into one round at the end of the 7 days.
Flag any ambiguity a client could argue about.The flag list is where AI is most useful. A typical flag: "consolidated" is undefined if a couple send separate lists. The fix is a sentence: "If more than one person sends comments, the client names one person to consolidate them." For a design practice that works with couples, that one sentence heads off a familiar argument.
A filled-in revision log
Pair the clause with a one-page log, kept in the project folder and shared with the client. Illustrative:
| Stage | Round | Comments received | Included or extra | Hours |
|---|---|---|---|---|
| Concept | 1 | 3 March (consolidated list of 14 items) | Included | 4.0 |
| Concept | 2 | 10 March (9 items) | Included | 2.5 |
| Concept | 3 | 17 March (11 items, new sofa direction) | Extra, quote sent | 3.0 at $120/h = $360 |
A log like this turns the clause from a threat into a courtesy. The client sees what has been used and what a further round costs before it is done.
Change orders for scope, not for taste
Changes differ from revisions: a change alters what you were hired to do. Examples: adding a bedroom to the scheme, moving from a refresh to a full redesign, or taking on project management after the contract said concept only. Prompt for a change clause with the same four jobs as in a building contract (written request, price before work, effect on timeline, approval before starting). The builder's version is covered in the remodelling contract tutorial, and the mechanism carries across: ask in writing, quote, approve, then start.
A quick sum shows why the line between revision and change matters. Say a $10,000 design project is contracted for a living room and kitchen. In week four the client adds a hallway and a study. Without a change clause, the studio can either absorb perhaps 20 hours of extra work (at a $120 hourly rate, $2,400 of time) or have an awkward conversation. With the clause, the studio sends a one-page change form with the extra fee and revised timeline, and the awkward conversation never happens because the process, not the designer, asks for the money.
Procurement terms: the clauses that carry the real risk
Buying furniture and finishes on behalf of a client turns a service contract into a service-plus-sales contract, and most interior design disputes about money start here. AI can draft the wording of whichever model you choose, but only a solicitor can say what each model means for your liability. The three common models:
| Model | How it works | Risk lands with |
|---|---|---|
| Client buys direct | You specify; the client orders and pays suppliers | The client, mostly; you carry specification risk |
| Studio buys as the client's agent | You order in the client's name, invoice a fee | Supplier and client, with you responsible for care in ordering |
| Studio buys as principal | You buy, then sell on to the client with mark-up | You: delivery, damage, returns and supplier failure |
Give the AI the model you use and ask it to draft: ordering (when and on what confirmation), deposits to suppliers (who pays and when), lead times (who bears delays), delivery and inspection (who checks, how long to report damage), returns (non-returnable made-to-order items), and substitutions (when you may swap an item and who must approve). Then ask for the usual flag list. A typical sample sentence: "Made-to-order items cannot be cancelled once ordered. We will tell you the cancellation terms before you approve any such item." That sentence needs a specific rule behind it, and the rule must be one your suppliers actually give you.
A realistic mistake in procurement wording
Picture a studio whose AI-drafted clause says only that "the studio will arrange delivery of all items to site". A sofa arrives damaged in transit and the client holds the studio responsible for the whole sum. The clause never said who inspects the delivery or by when damage must be reported, and it implied a duty the studio did not intend. The rewrite says the client or their representative inspects on delivery, notes damage on the delivery note, and reports within 48 hours with photographs, after which the studio pursues the supplier. The solicitor's part is to confirm whether that reporting window can be enforced and how it interacts with the client's own rights.
If you check trade quotes against your schedule before they reach the client, checking trade quotes with an AI tool fits straight into the procurement stage, and the contract should say you do it.
Timelines, client decisions and the approval clause
Design projects stall more often on client decisions than on designer effort, so the contract needs a mechanism for approvals. Ask the AI for a clause in which each stage deliverable is sent with a decision date, silence after that date triggers a reminder, and continued silence for a further period lets you either treat the stage as approved or pause the project and re-book your time. Which of those you choose is a business decision. Whether "silence counts as approval" is enforceable is a solicitor's question, so draft the alternatives and let them advise.
A filled-in example, illustrative: "We send the Stage 2 drawings on 14 April. Please reply with your approval or one consolidated set of comments by 21 April. If we have not heard from you by then, we will send a reminder. If we have not heard by 28 April, we will pause the project. Restarting may mean a new start date, depending on our other work." It is short, dated and explains the consequence, which is what a client can accept.
Site visits, measuring and what the fee includes
Scope lists are where small studios lose hours. Prompt the AI with your standard inclusions and exclusions: number of site visits per stage, a measured survey (or not), meetings by video or in person, supplier showroom visits, tender or quote comparison, snagging visits after installation. An AI-drafted list is usually tidy, but it tends to leave out the exclusion that matters most, which is anything not listed. Add a sentence: "Anything not listed here is not included, and we will quote for it separately."
A sample before-and-after: "Site visits as required" becomes "Two site visits in Stage 1 (survey and brief), one per month in Stage 3, and one snagging visit within 14 days of completion. Extra visits are charged at $[rate] with travel at cost." A client reading the second can see what they have bought, and you can see when a third visit means a quote, not a favour. Test the list against your last three projects: how many extra visits happened, and would each have been billable under the clause? If the answer is "none", the clause is too soft for how you actually work.
Using AI to review the finished contract against your own rules
Once drafted, ask a second question in a fresh chat so the model does not defend its own text: paste the contract and your fee notes and ask it to list every place the contract disagrees with the notes, every undefined term, and every clause with no deadline. Then a different pass: "Which clauses would a client most likely object to, and why?" The second list often predicts the questions a client will ask at signing, which you can pre-empt in your cover note. As AI clauses for agency contracts explains for creative agencies, a disclosure and approvals section that is clear on day one saves difficult conversations in month three.
Cancellation and termination
Prompt for two separate cancellation scenarios: the client ends the project before a stage starts, and the client ends it part-way through. For each, tell the AI what you would like to keep: fees for work completed, a share of the current stage, the deposit, and costs already committed to suppliers. A good output lists the amounts as formulas ("work done to date at the agreed rates, plus costs committed that cannot be cancelled") and promises a final account within a stated number of days. A solicitor then checks whether the right to keep a deposit or charge for committed costs holds up, and whether consumers have a cooling-off period that overrides your timeline.
Also draft your own right to end the contract: non-payment, abusive behaviour or an unreasonable delay in client decisions. Make the steps clear: notice, a short period to fix, then stop. The AI will draft this readily; the solicitor decides whether the notice periods are fair.
Ownership, credit and AI use
Designs, drawings and mood boards are intellectual property, and a contract should say who owns them, what the client may do with them, and whether you may photograph the finished project. Ask AI for short clauses on each: the client may use the design for the project but not pass the drawings to another designer without payment, you keep copyright in the drawings, and you may use photographs for your portfolio unless the client says no in writing. The reasoning is explained in AI for freelance designers without rights issues, including why a concept generated with AI needs care over ownership.
If your studio uses AI for mood boards or room visualisations, say so in a sentence and confirm that the final designs are yours and checked by you. The question of how much to say is covered in mentioning AI use in client contracts; draft the sentence with AI and let the solicitor confirm it.
Design-contract terms a solicitor should test
Take this table, the AI's flag lists and your main suppliers' terms to a fixed-fee review. Expect the purchasing rows to need the longest discussion, because they decide who carries the risk when a supplier fails or a delivery arrives damaged.
| Clause | Why a solicitor looks at it | Bring |
|---|---|---|
| Deposit amount, timing and refundability | Local rules may cap or regulate deposits and what happens on cancellation | Your typical fees and deposit percentage |
| Cooling-off and cancellation | Consumers may have statutory rights to cancel with required wording | How contracts are normally signed |
| Principal or agent in purchasing | Changes your liability for supplier failures and damaged goods | Your supplier terms and ordering process |
| Mark-up and fee disclosure | Buying as the client's agent can make an undisclosed mark-up or supplier commission a breach of duty; disclosure rules vary | Examples of how you charge |
| Limits on liability | Consumer law can override exclusions | Your professional insurance schedule |
| Late payment and pausing work | Notice and interest may be regulated | The wording you want |
| Intellectual property and licence of designs | Ownership and permitted use interact with local law | How clients use your drawings |
| Use of AI and data | Disclosure and data-handling wording may be needed | The tools you use |
| Dispute resolution | Mediation or arbitration clauses may be limited for consumers | Preferred process |
A solo designer builds a contract in an afternoon
Consider a solo designer who wants one contract for residential projects between $6,000 and $25,000, written in a single afternoon. Her steps, with illustrative times:
| Step | Time | What she ends up with |
|---|---|---|
| Plain notes: fee model, stages, revision rules, purchasing model, and every fee argument she has had before | 40 min | One page of rules in her own words |
| Prompting section by section, placeholders for client names and addresses, a flag list requested each time | 50 min | Draft sections, each with its own flag list |
| Consistency pass: "the Studio", "the Client" and "Stage" used the same way, working days throughout, every fee a placeholder or a figure she can defend | 20 min | One coherent draft |
| Merging the flag lists with the table above | 15 min | A single question list for the solicitor |
| Fixed-fee solicitor review | The solicitor's time | Deposit clause rewritten for local rules, a cooling-off notice added, purchasing changed from principal to agent |
The last change was her own choice once the solicitor explained it: buying as principal would have left her carrying the loss if a supplier failed mid-order. The result is a contract in her own voice with a solicitor-checked core, for a little over two hours of her time plus the review fee.
How AI misreads a design studio's contract
It assumes you are a builder
Drafts borrow warranty and defect language from construction contracts. A designer does not warrant workmanship by trades, and the clause can make you responsible for others' work. Tell the AI you design and manage, and do not build.
It treats every client comment as a revision
Unless the prompt defines a round, the draft says "unlimited revisions" or "reasonable revisions", both of which are invitations to argue. Define the round and cap it.
It hides the purchasing model
If you do not name principal or agent, the model picks one by accident, usually wording that makes you sound like both. Name the model in the prompt and check the output uses only that one.
It copies a fee percentage from nowhere
Models sometimes suggest "customary" deposits or mark-ups. Replace any figure you did not supply with a placeholder and a number you chose.
Keeping it working
Put a version date in the footer, keep a short log of changes, and revisit the contract when a project goes wrong: ask AI to draft a clause fix from a plain account of what happened, then take it to your solicitor at the next review. Keep the client-facing summary short, a one-page cover note in everyday words that sits in front of the contract, and make sure the contract text governs. For the wider routine of proposals, quotes and client updates around the contract, see AI for interior design studio admin. The tool writes drafts; the decisions inside the contract stay with you and your solicitor.
Questions designers ask about AI-drafted contracts
Can AI write my whole interior design contract?
It can write a readable first draft of each section if you supply your own fees, stages and rules. It cannot tell you which clauses are enforceable where you work. Use it for structure and plain wording, then have a solicitor review fees, deposits, liability, cancellation and procurement terms before first use.
How should a design contract charge for revisions?
State how many rounds are included at each stage, what counts as a round, and the hourly or fixed rate for extra ones. Ambiguity is the cause of most fee disputes, so define a revision as a change to an approved element rather than any client comment.
Is a deposit refundable if the client cancels?
That depends on your wording and on local consumer rules, which may limit what you can keep or require a cooling-off period. Draft the logic with AI, but ask your solicitor to confirm what is allowed and how the notice must read.
Who is responsible when ordered furniture arrives damaged?
Your contract should say whether you buy as principal or as the client's agent, who inspects deliveries, and how claims against suppliers are handled. These choices change your liability, so they are a solicitor's question, not a prompt's.
Should I tell clients I use AI?
Many designers state in the contract how AI is used, for example for drafting text or visualisation, and that final designs are theirs. The wording is a legal and trust choice, so draft it with AI and have your solicitor confirm it.
