How to Start a E-commerce Business

What it takes to legally start a e-commerce business in the US — licensing, structure, EIN, taxes, insurance, and your first customers. The steps are the same everywhere; the forms and fees depend on your state, so pick yours below for the exact links.

Typical startup cost
$1,000–$20,000 (inventory is the variable)

LLC for most
First customers
referrals + local search

  1. Check the licensing for e-commerce work

    You need a seller's permit in your home state and must monitor economic nexus in other states (register once your sales there cross a threshold, often $100k or 200 transactions). Marketplace facilitator laws mean Amazon/Etsy often collect tax for you. This is the part that varies most by state — some require a state license or registration before you can advertise, others leave it to the city or county. Confirm both your state board and your local government before you take a job.

  2. Decide what the business needs to open

    Selling physical products online through your own store or marketplaces. The setup areas that usually matter for a e-commerce business: Seller's permit + economic-nexus sales tax, Resale certificate for wholesale, Store platform + payments, Fulfillment (self, 3PL, or dropship), Product liability considerations. Typical cost to get operational: $1,000–$20,000 (inventory is the variable).

  3. Pick a structure — sole proprietor or LLC

    You can start as a sole proprietor with no filing, or form an LLC (usually $50–$300 depending on your state) for liability protection. For hands-on trade work where something can go wrong on a customer's property, most owners choose the LLC.

  4. Get a free EIN from the IRS

    An Employer Identification Number is free and takes a few minutes online. You need it to open a business bank account and to hire.

  5. Register for state taxes and get insurance

    Register with your state's tax agency if you'll collect sales tax, then line up general liability insurance — most contracts and license boards require proof of coverage.

  6. Get your first e-commerce customers

    Marketplaces for initial validation, then paid social and email for a branded store. Unit economics first — know your margin after shipping, fees, and returns before scaling ad spend. Repeat purchase rate and email are the compounding assets.
