A layout looks good on a board, but then old walls and site tolerances show up and everyone wants to know what's locked, what's buildable, and what happens when decisions change late. The interior design contract gives both sides one written set of terms to sign, so the work can move from survey to drawings without re-arguing the ground rules. The pages use blue‑green accents with Raleway headings over Inter body text, which keeps the document reading like a site-ready spec, not a moodboard.

The opening ties the terms back to the proposal you already accepted, so the same plan and rules apply from first survey through handover. The contract then names the deliverables the client gets, explains how the two-part payment works, and defines what counts as a revision round at each sign-off stage, including what happens when changes come after sign-off. Later sections cover who owns the finished work, how portfolio photography gets handled, what the designer is and isn't responsible for once construction starts, and how ending the project works, including what gets handed over once paid.

  • These terms cover our full-home interior Connects the contract to the accepted proposal so both documents follow the same plan and rules.
  • What we do Lists the finished work delivered at the end and notes the sign-offs that lock decisions before detailing and ordering.
  • Payment Defines the 50% upfront invoice, the final 50% on handover, 14-day terms, and when work pauses for late payment.
  • Changes Explains the included revision rounds at each stage and how extra changes get confirmed for timing and fee in writing.
  • Ending the project Covers ending in writing, what gets paid up to the end date, and what gets handed over once paid, with a signature section.

In Plutio, you change the names, dates, and rates to match your own terms, then send the contract to a client for online signing. Signed terms sit alongside the proposal the client accepted, so the paperwork stays consistent across both documents.

We went from spending hours on every proposal to creating fully customized ones in under 5 minutes. That's not an exaggeration - we timed it.

What we are responsible for

States responsibility for producing and coordinating the promised drawings and schedules, and draws the line at construction means, site safety, and trade workmanship.

Ending the project

Explains how the project ends in writing, what gets paid for up to the end date, what committed costs apply, and includes a Signature section.

Who it is for

Interior designers and interior decorators doing residential design or commercial interiors work who need written terms signed before drawings, schedules, and sign-offs start.

The contract in full

These terms cover our full-home interior design services for you, and they sit alongside the proposal you accepted. When something is described in the proposal and also covered here, we follow the same plan and the same rules, so decisions stay consistent from first survey through to handover.

What we do

We provide full-home interior design as a project service, taking you from measured survey through coordinated drawings and schedules that your builder and cabinetmaker can price and build from.

What you get is listed below. These items are the “finished work” we hand over at the end of the project. We will also ask for a few written sign-offs along the way, so we can lock decisions before we detail joinery or release anything for ordering. That is how we avoid expensive rework when old walls, thresholds, and site tolerances show up in real life.

* Existing plan set * Proposed layout plans * Finishes palette and schedules * Lighting plan and fixture schedule * Joinery drawings and detailing * FF&E schedule and purchasing list

Payment

To book the work, we invoice 50% of the total price when the proposal is signed. We start scheduling the survey and design time once that invoice is paid.

We invoice the remaining 50% when we hand over the finished work. Each invoice is payable within 14 days of its date. If a payment is late, we pause work that depends on that payment, including issuing drawings for construction, answering new site queries, or placing any orders that sit with us. As soon as the account is up to date, we pick up from the same agreed point and continue.

Changes

Your project includes two revision rounds at each sign-off stage: layouts, finishes, and lighting. A revision round means one set of changes gathered together and sent in one go, after you have reviewed what we issued. It is designed to keep decisions moving forward, not to keep options open indefinitely.

If you ask for changes after a stage is signed off, or you go beyond the included rounds, we will first confirm what needs rework, the effect on timing, and the added fee. We only do the extra work once you approve that change in writing. This is especially important when joinery has already been detailed, or positions on the lighting and electrical plan have been set.

Who owns what

Once the final 50% invoice is paid, you own the finished work we hand over, and you can use it to build and furnish this project at this address. That includes the drawings, schedules, and any specification documents we issue as part of the deliverables.

We keep ownership of our working files, templates, libraries, and internal tools, including draft sketches, test layouts, and background schedules that are not part of the deliverables. Those are how we work across projects. You are welcome to share the finished work with your builder, cabinetmaker, and trades for the purpose of pricing and building this project. Please do not sell or reuse it on another property without checking with us first.

Portfolio use

We may photograph or otherwise document the completed project and show it as part of our portfolio, including on our website, social channels, presentations, and awards submissions. We do this to show the quality of the layouts, detailing, and finished selections in real homes and spaces.

We do not share personal details. That means we do not publish your full name, your contact details, or anything you tell us is sensitive. If you want the project kept private, tell us in writing before we schedule photography or publish anything, and we will treat it as confidential. If you are fine with portfolio use but want a delay until after you move in or open, tell us and we will agree a timing that works.

What we are responsible for

We are responsible for producing the drawings and schedules we promise, and for coordinating them so the intent is consistent across layouts, finishes, lighting, and joinery detailing. We also coordinate with your builder and cabinetmaker by answering questions and issuing clarifications in writing, so the site team is working from one agreed set.

We are not responsible for construction means and methods, site safety, or the workmanship and accuracy of trades. Older buildings can be out of square, and site conditions can change once things are opened up. We measure on site and note anything that needs builder verification, and we rely on your builder and suppliers to confirm critical dimensions before ordering or cutting. We are also not responsible for supplier delays, backorders, discontinued items, or manufacturer defects.

Ending the project

If either of us needs to end the project, we will do it in writing. We will agree the notice period with you in writing based on what stage the project is at and what meetings, site visits, or deadlines are already booked.

Up to the end date, you pay for the work we have completed and any committed costs we cannot cancel. We will then hand over what is complete and paid for at that point, in a tidy package, so you can keep moving with your builder. Anything not yet started, or not yet paid for, stays with us. If you later want to restart, we can confirm what needs updating first, because site conditions and supplier availability often change.

Questions about this contract template

What should an interior design contract include?

An interior design contract usually covers the scope of work, the deliverables, payment terms, how changes and revisions work, who owns the drawings and schedules, responsibilities, and how the project ends. This template includes all of those topics as written sections, including a signature block.

How do interior designers handle revisions in a contract?

A contract can define what a revision round is and how many rounds are included at each stage, then explain what happens when changes come after sign-off. This template defines two revision rounds at each sign-off stage and requires written approval before extra work starts.

When do you pay an interior designer according to the contract?

Payment terms depend on the agreement, but the contract should say when invoices are issued, when work starts, and what happens if payment is late. This template invoices 50% when the proposal is signed, invoices the remaining 50% on handover, and uses 14-day terms with a pause on dependent work if payment is late.

Who owns interior design drawings and schedules?

A contract can separate ownership of the finished deliverables from working files and templates. This template transfers ownership of the finished work after the final payment, while the designer keeps ownership of working files, libraries, and internal tools.

Can an interior designer use my project photos in a portfolio?

A contract can allow portfolio use while keeping personal details private and giving the client a way to request confidentiality. This template allows portfolio photography and publication, excludes personal details, and lets the client require privacy or agree a delay in writing.

What happens if an interior design project ends early?

A contract should explain how termination works, what gets paid for, and what gets handed over so the build can continue. This template ends the project in writing, charges for completed work and committed costs up to the end date, and hands over what is complete and paid for.
