How Two Sisters Built a Cleaning Business in South Carolina

Starting a cleaning business with a family partner

Two sisters cleaning together can mean anything from a side hustle that pays for groceries to a full-time business with employees and a service area across multiple counties. The difference lies in how you structure the work, what you charge, whether you carry insurance, and how you handle taxes. Many successful cleaning operations in South Carolina started exactly this way—two people who knew how to work together, understood their local market, and built systems that let them scale without burning out.

The sister-partner model has real advantages. You already know how the other person works, you can cover for each other when life happens, and you can split the physical labor on larger jobs. But it also requires clear agreements about money, decision-making, and what happens if one person wants out. Starting without those conversations is how family businesses end up damaging relationships.

Key Takeaways

• Decide upfront whether you are operating as sole proprietors splitting jobs, a partnership, or an LLC, because each structure has different tax and liability consequences.
• Set a written agreement about how you split income, who handles scheduling and customer service, and what happens if one partner leaves.
• You will need general liability insurance before most commercial clients will hire you, and workers' compensation insurance if you hire employees.
• South Carolina does not require a business license for cleaning services, but you do need an EIN from the IRS and must report income on your taxes.
• Start by pricing based on square footage and job type, then adjust after your first month when you know how fast you actually work.

Choosing a business structure that protects both of you

The simplest structure is two sole proprietors who work together but file separate tax returns and keep separate business accounts. This works if you are splitting residential jobs 50-50 and want minimal paperwork. Each of you reports your half of the income on Schedule C of your personal tax return, and you each pay self-employment tax on your share.

A partnership is more formal. You file a partnership tax return (Form 1065), and the partnership itself does not pay income tax—instead, profits flow through to each partner's personal return. A partnership requires a written agreement that spells out how you split profits, who makes decisions, what happens if one partner wants to leave, and how disputes get resolved. Many sister teams use this structure because it clarifies who owns what and protects both people if the business gets sued.

An LLC (limited liability company) is a separate legal entity that protects your personal assets if someone sues the business. If you form an LLC in South Carolina, you file Articles of Organization with the Secretary of State and pay a filing fee. An LLC can be taxed as a sole proprietorship, partnership, or corporation depending on how many owners you have and what you elect. Most two-person cleaning businesses that form an LLC choose partnership taxation, which means filing Form 1065 and splitting profits on your personal returns.

Talk to a tax professional or small-business accountant before you decide. The cost of setting up an LLC or partnership is usually worth it if you are taking on commercial clients or hiring employees, because the liability protection matters. If you are only doing residential work and staying small, sole proprietorship may be simpler.

Getting the legal and tax foundation in place

South Carolina does not require a business license specifically for cleaning services, but you do need an Employer Identification Number (EIN) from the IRS. You can get an EIN for free at irs.gov, and it takes about 15 minutes online. You will need this number to open a business bank account, hire employees, and file business tax returns.

Open a separate business bank account in your business name. This keeps your personal and business money separate, makes tax time much simpler, and shows the IRS that you are running an actual business. Most banks in South Carolina will open a business account for a small monthly fee or no fee if you keep a minimum balance.

Register for South Carolina sales tax if you charge for services. Cleaning services are generally not taxable in South Carolina, but if you sell cleaning supplies or products as part of your service, those sales may be taxable. Check with the South Carolina Department of Revenue to confirm what applies to your specific services. If you do owe sales tax, you will need a sales tax permit and will file returns monthly or quarterly depending on your volume.

Set up a simple bookkeeping system from day one. Use a spreadsheet or accounting software like Wave (free) or QuickBooks to track every dollar in and out. Record what you charged, what the job was, when you did it, and what you spent on supplies. This makes tax time straightforward and shows you which jobs are actually profitable.

Insurance you need before taking on clients

General liability insurance protects you if you damage a client's property or someone gets hurt at a job site. Most commercial clients and property management companies will not hire you without proof of insurance. A general liability policy for a small cleaning business in South Carolina typically costs between $300 and $600 per year, depending on your coverage limits and claims history.

If you hire employees—even one person—you are required by South Carolina law to carry workers' compensation insurance. This covers medical bills and lost wages if an employee gets injured on the job. The cost depends on your payroll and the insurer's assessment of risk. You can get a quote from your insurance agent or from the South Carolina Workers' Compensation Commission.

Consider commercial auto insurance if you use a vehicle for the business. Your personal auto policy may not cover you if you are using the car for commercial purposes. Talk to your insurance agent about adding commercial coverage or switching to a commercial policy.

Get quotes from at least three insurance agents. Many insurers offer discounts if you bundle general liability with other policies, or if you have safety certifications or a clean claims history.

Pricing your services and managing the money

Most cleaning businesses in South Carolina charge by the hour, by the square foot, or by the job. Hourly rates for residential cleaning typically range from $25 to $50 per hour depending on your experience and the area, but this varies widely. Commercial cleaning often pays more because jobs are larger and more predictable. Start by researching what other cleaners in your area charge, then price based on how fast you actually work.

Square-footage pricing works well for residential jobs. Measure the home, estimate how long it will take you to clean, and divide your desired hourly rate by the square footage. For example, if you want to earn $40 per hour and you clean 1,000 square feet in 2.5 hours, you would charge $0.10 per square foot, or $100 for that job. Adjust this formula after your first month when you have real data on your actual speed.

For commercial clients, get the job specifications in writing: square footage, frequency (weekly, bi-weekly, monthly), what areas are included, and what supplies you provide versus what the client provides. Quote a monthly price so the client knows what to expect and you know what to budget.

Decide how you will split income between the two of you. Some sister teams split 50-50 regardless of who books the job. Others split based on hours worked, or one person handles admin and scheduling while the other does most of the cleaning work, and they adjust the split accordingly. Write this down and revisit it every six months or whenever the work balance changes.

Building systems so you can grow without chaos

Create a simple scheduling system so both of you know who is working when and where. Use a shared calendar (Google Calendar works fine) or a scheduling app like Acuity Scheduling or Housecall Pro. Include the client's address, phone number, job notes (pet allergies, areas to avoid, special requests), and which sister is assigned to the job.

Write down your cleaning process for each type of job—residential, commercial, move-out, deep clean. List the steps in order, note how long each step should take, and specify which supplies you use. This keeps the quality consistent whether one sister or both are doing the work, and it makes training easier if you hire a third person later.

Set up a simple contract or service agreement that clients sign before the first job. It should cover what is included in the service, your cancellation policy, how you handle payment, and what happens if the client is not satisfied. You do not need a lawyer to write this—many cleaning businesses use templates from SCORE (a free mentoring organization) or adapt language from other small-business contracts.

Handle payment upfront or immediately after the job. Many successful cleaning teams require payment by the end of the day or within 24 hours. This keeps cash flow steady and avoids the headache of chasing unpaid invoices. Offer multiple payment methods: cash, check, Venmo, PayPal, or Square.

Managing the sister dynamic and avoiding conflict

The biggest risk in a sister cleaning business is that work stress bleeds into the family relationship. Set clear boundaries: decide which sister handles customer complaints, which one manages scheduling, who decides whether to hire help, and how you will handle disagreements about money or work quality.

Have a monthly money conversation. Sit down together, review the income and expenses, confirm that the split feels fair, and talk about whether anything needs to change. Do this even if everything feels fine—it prevents resentment from building quietly.

Agree on what happens if one sister wants to leave the business. Does she sell her share to the other? Do you dissolve the business and split the assets? Can one person buy out the other's client list? Having this conversation before it becomes urgent saves a lot of pain.

If you form a partnership or LLC, put these agreements in writing. A partnership agreement or operating agreement does not have to be fancy or expensive—it just has to be clear and signed by both of you. This protects both sisters if there is ever a dispute.

Frequently Asked Questions

Do I need a business license to clean houses in South Carolina?

South Carolina does not require a business license specifically for cleaning services. You do need an EIN from the IRS and a separate business bank account. If you charge sales tax on any products you sell, you need a sales tax permit from the South Carolina Department of Revenue.

What if we want to hire a third person to help?

Once you hire an employee, you must carry workers' compensation insurance and withhold payroll taxes. You will also need to file quarterly payroll tax returns with the IRS and the South Carolina Department of Revenue. Many cleaning businesses start hiring when they have more work than the two of you can handle, which is usually a sign you can raise your prices or be more selective about jobs.

How do we split income if one sister does more work than the other?

You can split by hours worked, by jobs booked, by a percentage you both agree on, or by a salary-plus-profit model where one person gets paid for admin work and you split profits. Write down whatever you decide and review it monthly. If the split stops feeling fair, adjust it—this is a business decision, not a personal one.

What happens to the business if one sister moves away or wants to do something else?

This is why a written partnership agreement or operating agreement matters. Decide in advance whether the other sister can buy out the departing partner, whether you will sell the business as a whole, or whether you will dissolve it. Having this in writing before conflict happens protects both people.

Can we deduct cleaning supplies and equipment as business expenses?

Yes. Keep receipts for all supplies, equipment, and tools you buy for the business. You can deduct the cost of cleaning products, mops, vacuums, uniforms, vehicle expenses, insurance, and any software or apps you use to run the business. Talk to a tax professional about what counts as a deductible expense versus a capital asset.
