Your client approved the living room concept. Now they want you to redesign the adjacent dining room, at no extra cost. Or they expect you to manage contractor bidding, even though you only quoted design services. Or they're upset the custom sofa took 16 weeks, even though you never promised furniture procurement.
A scope of work stops these conversations before they start.
A scope of work defines the design services you're providing, what you'll deliver, and when the client will pay.
It separates design work (space planning, color schemes, furniture specs) from procurement (ordering furniture, managing deliveries) and project management (contractor coordination, installation oversight). It shows exactly how many revision rounds you'll provide on floor plans, renderings, and material selections.
Interior designers need this because projects involve multiple vendors, long lead times, and subjective client preferences. Without defined boundaries, "just one more tweak" becomes 15 unpaid hours of rework.
Interior design projects collapse in three predictable ways:
Your client texts: "Can you just pick a rug for the bedroom too?"
That "quick addition" means you’d need to source vendors, review dimensions, coordinate delivery timing, and manage returns if they don't like it. Three hours of unpaid work because you never specified which rooms you're designing.
Or they ask you to "swing by the site" during installation for a project management task that you didn't even quote. Now you're spending billable hours solving contractor problems.
A scope of work lists exactly which spaces you're designing and which services you're providing. When clients request additions, you reference this document and discuss additional fees before doing the work.
Pro Tip: Structure your services in tiers.
Tier 1: Design only (plans, specs, shopping lists).
Tier 2: Design + procurement coordination.
Tier 3: Full-service (design, procurement, installation management).
Price each tier accordingly, so clients know exactly what they're paying for.
If you use a project management tool like ManyRequests, you can use our Service Catalog feature to sell each tier of services you offer to look like this:

Some clients can be this way:
They review your furniture selections. They love the sofa but hate the chairs. You source new chairs. They want a different fabric. You provide samples. They circle back to the original chairs, but in a different finish.
Design projects may not come to an end if you don't add revision limits. The client will refine their preferences while you work for free.
Your scope of work specifies: "Two revision rounds on furniture selections. Additional rounds are billed at $150/hour”, and this prompts your clients to make decisions faster when they know revisions cost money.
You should also define revision timelines that won't drag the project out for too long. Let the client know if you need feedback within 5 business days, and how many days you’re willing to give revisions after you receive feedback. This way, you don't have to delay the project completion just because the clients didn't send in their input.
Client expects 3D photorealistic renderings. You quoted for hand-drawn elevations. The client thought you'd handle furniture delivery, when you specified design services only.
These miscommunications destroy client relationships and profit margins.
Your scope of work lists every deliverable:
It also shows realistic timelines: "Initial concepts: 2 weeks. Client review: 1 week. Revisions: 1 week. Final deliverables: 3 weeks after project start."
Clients know what they're getting and when they're getting it.
Build your scope of work with these seven components:
Specify exactly which design services you're providing and what clients receive.
Space Planning:
Design Development:
Documentation:
If you're offering procurement or project management, list those as separate services with their own deliverables and fees.
Break the project into clear phases with completion dates.
Phase 1: Discovery (Week 1-2)
Phase 2: Concept Development (Week 3-4)
Phase 3: Design Refinement (Week 5-6)
Phase 4: Documentation (Week 7)
You should also set realistic timelines. Write that custom furniture takes 12-16 weeks. Tile orders need 6 weeks. Factor in client response time—if they take two weeks to review concepts, the project timeline extends.
State what's not included in the project. Interior design projects can blur into procurement, project management, and construction supervision, so it's important to define your boundaries.
Add that this project does NOT include:
When clients ask for these services mid-project, you can reference the document to show them that it's not included in the project, and you charge them separately for the additional service.
Design is subjective. State how many rounds of design you're willing to go through, before you bill them for extra work.
Add that:
Revision Rounds:
Revision Timeline:
What Counts as a Revision:
This prevents the endless "can we try one more option" cycle that kills profitability.
Clarify who's responsible for what financially.
Design Fees (Your Responsibility):
Furniture and Materials (Client Responsibility):
Client Provides:
With interior design, you know the approval process can drag the project out longer than intended. To avoid this, define who reviews what and how decisions get made, and you don’t have to chase them around with follow-ups.
For example:
Primary Contact:
Review and Approval Process:
Response Times:
Specify when you get paid and what happens at project end, depending on the agreement you made at the beginning of the project.
Payment Schedule:
Project Completion:
Post-Project Support:
Here's how to customize our free Graphic design scope statement template to fit your agency's needs:
Interior design projects have so many blurred lines that may cause you to do more than agreed if you don't set your boundaries early. We designed this scope of work to help you avoid scope creep that could drag the project on for a long time without pay.
And if you experience this with many clients, ManyRequests can help you track all client requests, give you add-on features to bill extra requests they may have. We also provide a white-label client portal that lets you have full control over every client request, your team, and client relationship.
