20 Steps to Start an Interior Design Business

20 Steps to Start an Interior Design Business

If you want to turn a talent for space, color, and furniture into a paying career, starting an interior design business puts that skill to work on your own terms. This guide walks you through every practical step—from validating your concept to landing repeat clients—so you can build a sustainable interior design business with clear footing from day one.

Whether you shoot photographs, design interiors, build software systems, or lay out graphics, this guide walks you from a first idea to a working business. You already have a skill people want. What follows turns that skill into a creative professional business that can be paid, insured, and grown. Read it on your phone, do one thing a week, and you will get there.

Have you sold this to anyone, ever?Have you registered a legal entity?
No + NoStart at step 1 — you have an idea
Yes + NoStart at step 6 — you're earning, informally
No + YesStart at step 9 — registered, no revenue yet
Yes + YesStart at step 12 — operating, formalising

Most people who read this arrive already earning. You may have shot a wedding, designed a friend's logo, or built a small database for cash, with no paperwork behind it. That is a real business. The work came first, and the paperwork catches up to the work — not the other way round. Find the row above that fits you, and start there. You are not behind.

1. Decide you're doing this

Before anything else, decide that this is a business and not a favour you keep doing for free. That decision changes how you talk about your work and what you ask for it. This week, write one sentence: "I am building a business doing ___." Say it out loud. Tell one person who is not a client. The point is not paperwork or a plan — it is committing to treat your skill as something people pay for, on terms you set. Everything after this step gets easier once you have made this call. You can still keep a day job. You can still start small. But from now on, you are running something, not just helping out.

2. Define the one thing you sell

You may be able to do many things — shoot portraits, retouch, design, code, style a room. Pick one thing to lead with. Not because the others don't matter, but because a clear offer is easier to sell and easier to price. This week, write down the single service you want most people to hire you for, in one plain line: "I make ___ for ___." Resist listing everything. A photographer who says "brand photos for small shops" gets remembered; one who says "all kinds of photography" does not. You can add services later. Right now, name the one thing that is the front door to your work.

3. Name who buys it

An interior design business sells direct to its clients rather than through intermediaries, so understanding who those clients are is essential. Finance and insurance operations—banks, investment firms, and insurance companies—routinely hire designers to fit out branch offices, headquarters, and client-facing spaces where environment signals credibility. Public administration clients, including government agencies and municipal bodies, commission interior design work for civic buildings, courthouses, and public facilities, often through a formal procurement process. Data hosting and technology companies are another consistent source of commercial work, as server-facility support offices and corporate campuses require designed interiors. Residential homeowners, property developers, and hospitality operators round out the broader client picture for an interior design business, and the mix you pursue will shape your portfolio, your contracts, and your marketing from the beginning.

4. Make one sale

Nothing tells you the business is real like one person paying you for the thing in step 2. If you have already sold work, you have done this — good. If not, your job this week is to make one sale, however small. Message three people who fit the buyer you named and offer the one thingyou defined. Name a price. Do the work. Get paid. A single real sale teaches you more than weeks of planning: what people actually want, what they'll pay, what parts of the job you enjoy or dread. Keep a note of how it went. That note becomes the raw material for pricing, your process, and everything in the phases ahead.

5. Choose how you'll be organised

If you are already earning, you are likely operating as a sole proprietor without knowing it — that is the default, and it is legitimate. Now choose deliberately. The common options for a creative professional are a sole proprietorship, a partnership if you work with someone, or a limited liability company that separates your personal money from the business. The main questions are how much personal risk you want to carry and whether you plan to bring in help. This week, read a plain-language comparison of these structures from your state's business office or the U.S. Small Business Administration. Don't file anything yet. Just decide which shape fits the work you're doing and the risk you're taking on.

6. Register the entity

If you picked something other than a plain sole proprietorship, this is where you make it official with your state, usually through the Secretary of State or an equivalent business registration office. You are not fixing a mistake by doing this now — you are formalising work that already exists. This week, find your state's business filing website and read what registering your chosen structure involves, then file if you're ready. If you're staying a sole proprietor but working under a name other than your own, you may need to register that name locally. Keep whatever confirmation you receive; you'll need it to open a bank account and set up tax accounts in the steps ahead.

7. EIN, state and local registration

An EIN is a federal tax number for your business, issued free by the IRS. You can get one even as a sole proprietor, and it lets you keep your Social Security number off invoices and forms. Beyond the EIN, most places require you to register with your state's tax authority if you'll collect sales tax, and many cities require a general business registration to operate within their limits. This week, apply for your EIN through the IRS website — it takes minutes — and search "[your city] business registration" to see what your locality asks for. These are routine registrations, not judgments. They simply put your working business into the systems that already assume it exists.

8. The permission this work requires

An interior design business typically requires a state-issued interior design or interior designer licence, granted by your state's licensing board for design or architecture-related professions. In many states, using the title "interior designer" or "registered interior designer" is a protected designation that requires documented education, examination, and supervised experience before the board will issue a credential. Some states fold this review under a broader design or construction licensing authority. The specific requirements vary meaningfully by state, so confirm every condition directly with your state's licensing board before accepting a paying client for your interior design business. Beyond the state licence, standard business registrations—entity formation, a local business licence, and a sales tax permit if you resell furnishings—also apply.

9. Business bank account

Open a bank account for the business and run all its money through that account. This is the single move that turns tangled personal-and-business finances into something you can actually read. Mixing the two makes taxes harder and, if you formed an LLC, can weaken the separation that protects your personal money. Most banks will ask for your EIN and your registration confirmation from steps 6 and 7, so have those ready. This week, compare two or three banks or credit unions on monthly costs and whether they handle the card payments you take, then open one. From now on, clients pay into this account and business costs come out of it. Nothing personal.

10. Price the work

The first money spent launching an interior design business goes in a predictable order. Entity formation and licensing fees come first, because you cannot legally operate without them. Next is professional liability (errors and omissions) insurance, which most residential and commercial clients will require before signing a contract. After that, software costs arrive quickly: project management platforms, floor-plan and rendering tools, and accounting software are all near-daily necessities. A professional portfolio—whether a polished website, printed lookbook, or both—follows, because your ability to win clients depends entirely on showing past work. Finally, early operating overhead includes a dedicated phone line, basic office supplies, and any co-working or studio space you need to meet clients. The range for all of this varies considerably depending on your state's licence fees, the software tier you choose, and whether you work from home or lease space.

11. Insurance

Creative work carries real risks: a client claims your design cost them money, gear gets stolen, someone trips over a light stand at a shoot. Insurance is how you keep one bad event from ending the business. The common types for a creative professional are general liability, professional liability (sometimes called errors and omissions), and coverage for your equipment. If you work in clients' homes or spaces, or handle expensive gear, these matter more. This week, ask two insurers or an independent broker for quotes on general and professional liability, and describe your actual work honestly so the coverage fits. Some clients and venues will require proof of insurance before they hire you, so having it also opens doors.

12. Find your suppliers

Running an interior design business means coordinating a wider supply chain than most clients realize; what follows names only a portion of it. Office equipment wholesalers Office Equipment Wholesalers supply the workstations, monitors, and presentation hardware a designer depends on daily. Architectural, engineering, and related services firms Architectural, engineering, and related services become critical partners when a project involves structural changes, permit drawings, or MEP coordination that falls outside the designer's own scope—subcontracting to these professionals is common on commercial and renovation work. Data processing and hosting services Data processing, hosting, and related services underpin the cloud-based rendering, project-management, and file-sharing tools that have become standard practice. The full set of supplier relationships for an interior design business is larger than these examples and shifts depending on whether you focus on residential, commercial, or specialized hospitality work.

13. Write down how you do it

Write down how you deliver your work, step by step, from first enquiry to final handover. For a creative professional this usually covers: how a client contacts you, what you agree in writing, how you take a deposit, how you do the work, how you deliver files or the finished space, and how you get the balance paid. Writing it down does three things: it makes your work consistent, it lets you spot where money or time leaks out, and it means you can hand parts of it to someone else later. This week, open a note and list every step of your last job in order. That list is the first draft of your process. Refine it each time you work.

What you just wrote down is your Standard Operating Procedure (SOP). BLKB2B keeps a free starter SOP library for your exact business type — see your SOPs →

14. Records and bookkeeping

Keep track of what comes in and what goes out, from day one. You don't need anything fancy — a simple bookkeeping tool like QuickBooks, or even a clean spreadsheet, will do to start. The goal is that at any moment you can answer: how much did the business earn, what did it spend, and what's left. Save every receipt for gear, software, travel, and supplies, because these lower what you owe at tax time. This week, set up your chosen tool and enter every transaction from the last month, using your business bank account as the source. Do this weekly from now on. Fifteen minutes a week beats a panicked weekend before taxes are due.

15. Tax setup

As a business, you're responsible for setting aside and paying your own taxes, which no employer is doing for you. Depending on where you are and how you're structured, this can include income tax, self-employment tax, and sales tax on certain services or goods. The reliable habit is to move a portion of every payment into a separate savings account the moment it lands, so the money is there when taxes are due. This week, open that savings account and pick a percentage to set aside — a tax professional can tell you the right figure for your situation and structure. Consider a short paid session with an accountant now; it usually saves more than it costs by catching things early.

16. First help — contractor or employee

The moment you can't take on more work alone, you have a choice: hire a contractor for specific jobs, or take on an employee. A contractor — a second shooter, a retoucher, a developer for one project — is simpler, handles their own taxes, and works job to job. An employee costs more in payroll and obligations but gives you steady, controllable help. Misclassifying an employee as a contractor causes real problems, so learn the difference before you commit; the IRS and your state labour office publish plain guidance on where the line sits. This week, if you're turning work away, write down which parts of your process you'd hand off first. That tells you exactly who to look for.

17. Find buyers

The first three sales for a new interior design business almost always come from within your existing network before any marketing takes effect. Start with friends, family, or former colleagues who are renovating, relocating, or outfitting a new home or office—these clients accept portfolio-building rates in exchange for documented, photographed results you can show everyone else. Second, introduce yourself to residential real estate agents in your area; they stage and sell homes constantly, refer clients who just bought a property and want to personalize it, and a single agent relationship can generate referrals for years. Third, reach out directly to small commercial tenants—a new restaurant, a boutique, a professional services firm moving into a new office—who need a designed space but lack a procurement department. These three channels require no advertising budget, only direct outreach and a clear explanation of what your interior design business delivers.

18. Get listed and get verified

Make it easy for people to find you and trust you before they ever speak to you. That means claiming your business on the places clients look: a Google Business Profile, the main directories for your field, and any review platforms where past clients can vouch for you. Verification — the checkmarks and confirmed listings — signals to a stranger that you're a real, established business. This week, claim or update your Google Business Profile and one industry directory, and ask two past clients to leave an honest review. Fill every field: your one clear offer from step 2, your area, photos of real work. A complete, verified listing beats a half-empty one every time, and it works for you while you sleep.

19. Check yourself against industry figures

Once you've been running a while, step back and compare your business to others in your field. How does your pricing sit against typical rates? How much of your revenue goes to costs, and is that normal for your kind of work? Are you charging enough to make a living, not just to stay busy? Industry associations and public data sources publish benchmarks for creative fields — typical margins, common rates, seasonal patterns. This week, find one such figure that matters to you and honestly measure yourself against it. The point isn't to copy others; it's to see where you're an outlier, so you can decide on purpose whether that's a strength to keep or a gap to close.

20. Write the plan

Now that you know your offer, your buyers, your prices, and your numbers, write the plan you skipped at the start — and it will actually mean something, because it's built on real experience instead of guesses. Keep it short: what you sell, who buys it, how you reach them, what it costs to run, and what you want the next year to look like. A tool like LivePlan can give you a structure to fill in, or a single page in a document works fine. This week, draft one page covering those five things. Revisit it every few months. The plan is not a formality; it's how you decide where the business goes next instead of just reacting to whatever comes in.
