7/2/20269 min read
Thinking about starting an online business but not sure whether you need an LLC, a sole proprietorship, or something else? You're not alone.
One of the first questions new entrepreneurs ask is:
"Do I really need to form a business before I start selling?"
The answer depends on your goals, the type of business you're starting, and how much protection you want for yourself and your personal assets.
The good news is that choosing a business structure doesn't have to be confusing. Once you understand the basics, you'll be able to make a confident decision and move forward knowing you're building your business on a solid foundation.
In this guide, we'll walk through the most common business structures for online entrepreneurs, explain when you should consider forming an LLC, discuss whether you need an Employer Identification Number (EIN), and help you avoid the mistakes many first-time business owners make.
Whether you're planning to sell digital products, offer freelance services, start a consulting business, or launch an online store, this guide will help you choose the right path.
Why Your Business Structure Matters
Your business structure affects much more than paperwork.
It can influence:
Your personal liability
How you pay taxes
How you open business bank accounts
Whether clients see you as a professional business
How easily your business can grow in the future
Choosing the right structure from the beginning can save time, money, and frustration later.
The good news is that your first decision doesn't have to be your final decision. Many successful businesses begin as sole proprietorships before transitioning to an LLC as they grow.
Do I Even Need to Form a Business?
The short answer is:
No—not immediately.
Many entrepreneurs begin as sole proprietors.
In fact, if you start selling products or services without forming a separate legal entity, you're automatically operating as a sole proprietorship in most states.
For someone testing a business idea, this can be a practical way to get started.
For example, if you create your first digital planner, printable, or online course and make a few sales, there's generally no requirement to form an LLC before you can begin.
However, that doesn't mean remaining a sole proprietor is always the best long-term choice.
As your business grows, you'll likely want additional legal protection, a more professional business image, and a structure that separates your personal finances from your business activities.
That's when many entrepreneurs decide to form an LLC.
The important thing is this:
Don't let uncertainty about business formation stop you from getting started.
Many successful businesses started small, validated their ideas, and formed an LLC once they knew they had a profitable business worth protecting.
Sole Proprietorship vs. LLC
These are the two business structures most first-time online entrepreneurs consider.
Let's compare them.
Sole Proprietorship
A sole proprietorship is the simplest way to operate a business.
There are no organizational documents to file to create the business itself, and setup costs are generally low. If you're operating under your own legal name, the administrative requirements are often minimal, though local or state registration requirements may still apply depending on your circumstances.
Advantages
Easy to start
Low startup costs
Simple tax reporting
Complete control over business decisions
Good option for testing a new business idea
Disadvantages
No separation between personal and business assets
You are personally responsible for business debts and obligations
Can appear less established to some clients or lenders
Future growth may require changing your business structure
For many people selling their first digital products, a sole proprietorship is simply the starting point—not necessarily the final destination.
Limited Liability Company (LLC)
An LLC creates a separate legal entity under state law.
One of the primary reasons business owners choose an LLC is that, when properly maintained, it can help separate personal assets from business obligations. The extent of that protection depends on many factors, including compliance with applicable laws and how the business is operated.
LLCs have become one of the most popular choices for small businesses because they offer flexibility while remaining relatively straightforward to manage.
Advantages
Separates your business from your personal assets
Creates a more professional business image
Makes it easier to open business banking accounts
Can simplify adding partners or members later
Often provides greater credibility with vendors and customers
Disadvantages
Formation costs vary by state
Ongoing state filing requirements may apply
Additional recordkeeping is generally recommended
Some states require annual reports or renewal fees
Which One Is Right for You?
For someone who is still exploring an idea, creating a first digital product, or validating a new business concept, starting as a sole proprietor can be a practical choice.
However, if you're committed to building a long-term business, signing contracts with clients, hiring contractors, or creating valuable intellectual property, an LLC is often worth considering because it provides a more formal business structure.
The key is to choose the option that fits where your business is today, while planning for where you want it to be tomorrow.

The biggest mistakes first-time entrepreneurs make.
When Should You Form an LLC?
There isn't one perfect time to form an LLC. The right time depends on where you are in your business journey.
Many successful business owners start as sole proprietors while they validate their business idea. Once they begin earning consistent income or taking on greater responsibility, they decide to form an LLC.
You may want to consider forming an LLC if:
You are consistently making sales.
You're signing contracts with clients.
You're hiring freelancers or independent contractors.
You have valuable digital products or intellectual property to protect.
You want to separate your personal finances from your business.
You want to build a long-term business rather than simply test an idea.
Remember, forming an LLC doesn't make your business successful—it simply provides a business structure that may better support future growth.
Can I Start as a Sole Proprietor and Change Later?
Absolutely.
Many entrepreneurs begin as sole proprietors because it's inexpensive and allows them to start quickly.
As the business grows, they later form an LLC.
This is a common progression for small businesses.
For example:
Sarah creates printable planners and sells them online. During her first six months she earns a few hundred dollars while learning what customers want. Once sales become consistent and she begins expanding her product line, she forms an LLC to support her growing business.
There is nothing wrong with starting small.
The important thing is to keep good business records from the beginning so that the transition is easier later.
Do I Need an EIN?
An Employer Identification Number (EIN) is a federal tax identification number issued by the IRS.
Many first-time business owners assume they only need an EIN if they have employees.
That's not always the case.
An EIN can be useful because it may allow you to:
Open a business bank account.
Apply for certain business licenses.
Work with vendors who request a business tax ID.
Keep your Social Security Number more private when completing business paperwork.
If you form an LLC, obtaining an EIN is often one of the next steps in setting up your business.
Many sole proprietors also choose to obtain one.
The IRS currently provides EINs online at no cost.
Do I Need an Operating Agreement?
If you're forming an LLC, I strongly recommend having an Operating Agreement—even if you're the only owner.
An Operating Agreement explains how your business is organized and how it will operate.
It can include information such as:
Who owns the business.
How important decisions are made.
How profits are handled.
What happens if another owner joins later.
Procedures for dissolving the business.
Even when your state doesn't require one, having an Operating Agreement demonstrates that you're treating your business as a separate entity and helps keep important decisions documented in writing.
If you're operating as a sole proprietor, an Operating Agreement generally isn't applicable because there isn't a separate LLC entity.
How Much Does It Cost to Start an LLC?
The cost of forming an LLC varies by state.
Typical expenses may include:
State filing fees.
Name reservation fees (if applicable).
Registered agent fees (if you hire one).
Annual reports or renewal fees in states that require them.
Some entrepreneurs also choose to hire an attorney or business formation service, while others complete the filing themselves.
Before filing, always check the current filing requirements and fees with your state's business filing office.
Common Mistakes First-Time Business Owners Make
Starting a business is exciting, but many new entrepreneurs make the same avoidable mistakes.
Here are some of the most common:
Waiting for Everything to Be Perfect
Many people spend months researching instead of taking action.
Perfection isn't required to start.
Progress is.
Mixing Personal and Business Finances
Using one bank account for everything makes bookkeeping much more difficult.
Keeping business finances separate from the beginning will save time and reduce confusion later.
Skipping Written Agreements
Many people rely on verbal agreements with freelancers, contractors, or business partners.
Having simple written agreements can help clarify expectations and reduce misunderstandings.
Forgetting Website Legal Documents
If you have a website, visitors expect to find documents such as:
Privacy Policy
Terms & Conditions
Disclaimer
These documents help explain how your website operates and what visitors can expect.
Not Protecting Confidential Information
If you're sharing business ideas, customer information, pricing, or proprietary processes, a Non-Disclosure Agreement (NDA) can help establish expectations about confidentiality before information is shared.
Trying to Do Everything at Once
Many entrepreneurs feel they need to build a website, create products, launch social media accounts, start a blog, and learn marketing—all at the same time.
A better approach is to focus on one step at a time.
Build a solid foundation first.
Then continue adding to your business as it grows.
Build Your Business One Step at a Time
One of the biggest misconceptions about starting a business is that everything must be completed before you can begin.
In reality, successful businesses are built in stages.
Start with a clear idea.
Choose the business structure that makes sense for your current situation.
Keep good records.
Protect your business with the appropriate documents.
Continue learning as your business grows.
Small, consistent progress often produces better long-term results than trying to do everything perfectly on day one.
Recommendation for Most Digital Product Businesses
One of the questions I hear most often is:
"What would you do if you were starting an online business today?"
While every situation is different, here's the approach I generally recommend for new entrepreneurs who are selling digital products, offering freelance services, or building an online business.
Step 1: Start
Don't wait until everything is perfect.
Create your first product, launch your website, and begin learning what your customers actually want.
The sooner you start, the sooner you'll gain valuable experience.
Step 2: Stay Organized
Keep good records from the beginning.
Separate your business activities from your personal life as much as possible.
Develop systems that will grow with your business.
Step 3: Protect Your Business
As your business begins to grow, consider whether it's time to form an LLC and implement basic legal documents that help protect your business.
Building a solid foundation today can help prevent costly problems later.
