Are you an interior designer or decorator looking to create a comprehensive and professional design contract for your clients? In this article, we will guide you through the essential elements of a successful interior design contract and provide valuable insights to ensure a smooth and effective collaboration with your clients.

Crafting a Solid Interior Design Contract

A well-prepared interior design contract is crucial for establishing clear expectations, protecting your rights, and ensuring a mutually beneficial working relationship with your clients. Here are the key components to consider when drafting your contract:

Statement of Work

Clearly define the scope of work and outline the design services you will provide. Specify the client's requirements and expectations, as well as the agreed-upon compensation for your services. This section will serve as a foundation for the entire contract.

Changes to Project Scope

Account for the possibility of changes in the project scope after work has commenced. Set guidelines for how to address such situations to avoid misunderstandings or disputes with your clients.

Project Timeline

Establish a realistic timeline for project completion. If necessary, break it down into stages to ensure efficient progress and effective communication with your clients.

Approval Process

Define the approval process for each stage of the design development, from initial plans to the finished product. Clearly outline the steps involved and ensure that both you and your client are satisfied with the progress at each stage.


Set a budget early on and allow for potential budget changes. Communicate transparently with your clients about any cost fluctuations and obtain their consent before proceeding with additional expenses.

Failure to Pay

Anticipate potential scenarios where mistakes occur or the client fails to make payments. Clearly articulate the consequences and actions to be taken in such situations to protect your interests.


Establish how the contract can be terminated. Define the conditions under which either party can end the agreement and outline any relevant termination procedures.

Standard Clauses

When drafting your interior design contract, consider including standard clauses that address potential scenarios affecting the progress of the project. By clearly setting out your responsibilities as a designer and emphasizing your commitment to professionalism, you can prevent conflicts and ensure a smooth collaboration with your clients.

Scope of Interior Design Services

The scope of interior design services forms the core of your agreement. It outlines the specific tasks and expectations for the project. Consider dividing the scope into phases or stages to facilitate effective communication with clients.

First Stage: Conceptual Phase/Initial Stage

During the conceptual phase, meet with the client to define their needs and expectations. This is where you lay the groundwork for the project. Key considerations during this phase include consultation, space allocation, meetings, and sketch development.

Practical Considerations

During the initial meeting with your client, discuss their proposed design needs and assess the space where the services will be performed. Consider factors such as lighting, fixtures, existing furnishings, and the client's preferences. If necessary, work with other consultants to ensure a comprehensive and cohesive design.

Second Stage: Design Development/Intermediate Stage

In this phase, you begin developing concrete plans and drawings based on the client's feedback. Specify details such as payment for plans, revisions, ownership of the designs, and the client's involvement. Additionally, consider whether subcontractors or consultants will be involved and if the client needs to approve their use.

Third Stage: Contract Administration/Final Stage

During the final stage, the project moves from concept to reality. Your role is to coordinate various aspects, including delivery, installation, and supervision. Outline your responsibilities in terms of assisting with competitive bids, coordinating schedules, and supervising installations. Provide your client with a checklist of completed and pending items and ensure their satisfaction with the final results.

Contractual Questions to Ask

To ensure a comprehensive and successful design contract, ask yourself important questions such as:

  • Is the workload reasonable and within the scope of your expertise?
  • Do any contract requirements go beyond the usual services you provide?
  • Should there be cost estimates at each stage, considering potential fluctuations?
  • How do you handle payments and late payments?

By addressing these questions, you can avoid misunderstandings and create a contract that meets both your and your clients' expectations.

Getting Paid

Clearly communicate your billing terms to avoid miscommunication and ensure prompt payment from your clients. Consider different payment options, such as fixed-price, hourly, or project-based billing. Specify when payment is due and establish measures for late payments.

Out of Scope Charges

Specify that any services or expenses outside the agreed-upon scope of work will be invoiced separately. Address scenarios where additional revisions or unforeseen expenses arise and determine the rates for such situations.

The "What If's"

Account for potential issues and changes that might arise during the project. Consider scenarios such as extended project timelines, budget modifications, changes to the program, or defective furniture. By addressing these contingencies in your contract, you can protect yourself and ensure that you are compensated for your work.


Establish conditions for terminating the contract to safeguard both parties' interests. Consider allowing for a "cure" period to address any defaults before terminating the agreement. Additionally, document any work completed or pending at the time of termination.

Miscellaneous Considerations

Include a miscellaneous section to address any other important considerations that may arise during the course of the project. Clarify your responsibilities regarding product appearance, quality, or workmanship, and establish who is responsible for obtaining permits or licenses. Additionally, outline your rights to use project photos for your portfolio and account for any interruptions or delays beyond your control.

It's important to note that this article serves as friendly advice and reflects personal viewpoints. For legally-binding contracts, we recommend consulting an attorney or using legal document services to ensure compliance with local laws and regulations.

Creating a well-crafted interior design contract not only protects your rights but also sets clear expectations and fosters positive client relationships. Prioritize effective communication, transparency, and professionalism throughout your design projects to ensure long-lasting success.
