In this competitive market and a rising interior design industry, you will need a step-by-step guide for starting and growing your interior design venture. If you’ve ever envisioned turning your passion for design into a flourishing business, you’re in the right place.

From laying the foundation with a solid business plan to attracting clients, we’re here to guide you through each step required to build a successful interior design business.

So, let’s dive in.

Why Should You Start an Interior Design Business?

The demand for interior designers is currently sky-high. Interior design is a creative skill required in both residential and commercial spaces. It involves an artistic vision that can turn a boring place into a “WOW!”

Interior design offers flexibility—you can work independently, collaborate with firms, or specialize in niche markets like sustainable or luxury design. The financial growth potential is significant, especially as you build a strong portfolio and network. If managed well, interior design can be a promising business idea.

Benefits of starting an interior design business:

  • High demand in residential and commercial sectors
  • Potential for financial growth with experience
  • Flexibility to work independently or expand into a full-scale firm
  • Makes a real impact by enhancing people’s living and workspaces

Now that we have determined why you should start an interior design business, let’s discuss how to do so step-by-step!

How to Start an Interior Design Business Successfully?

1. Make a Business Plan

To create a business strategy, first investigate and analyze your competitors to identify your unique selling features. Outline the services you intend to offer, whether residential design, commercial spaces, or a specific niche.

You may examine and revise your strategy regularly to meet the changing demands of your business and the dynamic interior design market. A successful business interior design plan will help you create a growing firm.

For example, suppose you are initially planning on providing interior design services for commercial firms or restaurants, but, you say “YES” to a Kitchen interior design without any planning or knowledge. In this case, your business could collapse even before you start.

When your resources are available for commercial interior design work, it can’t go with Kitchen interior design.

This is the reason why proper planning and correct decision-making is essential when you start a business.

2. Choose Your Business Name and Structure

Selecting an appropriate business name and structure are pivotal decisions. It will be instrumental in the development of your interior design company strategy.

Once you’ve settled on a name, it’s time to determine the business structure that aligns with your goals and preferences. Combining a compelling business name and a suitable structure lays the foundation for a strong and recognizable interior design enterprise.

Your business structure determines how you pay taxes, your liability, and how you operate. The most common structures for an interior design business are:

types of interior design business structure

    a) Sole Proprietorship

    • Simplest and most cost-effective structure.
    • You operate as an individual, and all profits/losses are yours.
    • Personal liability: If your business incurs debt or legal issues, your assets are at risk.
    • Best for freelancers or solo designers starting with minimal risk.

    b) Limited Liability Company (LLC)

    • Offers personal liability protection, meaning your assets (home, savings) are separate from business debts.
    • More credibility with clients and vendors.
    • Flexible tax structure: You can choose to be taxed as a sole proprietor, partnership, or corporation.
    • Ideal for small to medium-sized interior design firms.

    c) Corporation (C-Corp or S-Corp)

    • Separate legal entity from its owners, providing strong liability protection.
    • C-Corp: Profits are taxed at both corporate and personal levels (double taxation).
    • S-Corp: Avoids double taxation but has ownership restrictions.
    • More paperwork and higher setup costs but beneficial for large-scale firms with multiple stakeholders.

    d) Partnership (for businesses with multiple owners)

    • General Partnership (GP): All partners share profits and liabilities.
    • Limited Partnership (LP): One partner has unlimited liability, while others have limited liability.
    • Limited Liability Partnership (LLP): All partners have limited liability, similar to an LLC.

3. Register Your Interior Design Business and Get an EIN

After settling on a business name and structure, formally registering your interior design firm is the next crucial step.

This is your company’s unique identification, which is used for tax, banking, and other official documents.

With your business officially registered and equipped with an EIN, you are well on your way to operating your interior design business legitimately and organized.
