Opening a Business: 10 Steps From Idea to First Customer

A plain-English guide to opening a business in the US: validate the idea, pick a structure, get an EIN, fund it and launch, with real costs and sources.

Illustrated first sale at a small business

Opening a business in the US comes down to two jobs: proving someone will pay for your idea, then handling the legal and financial setup so you can take their money. Most people do the paperwork first and the proof never. Flip that order and you save yourself months and a fair bit of cash.

Below is the whole path, in order, with the official sources for each step. It works for a side project, a micro-business or a full-time leap.

TL;DR

  • Validate first: talk to buyers and size your costs before you file anything.
  • The legal core is short: choose a structure, register the name, get an EIN (free from the IRS), then handle state and local licenses.
  • Count monthly costs, not just one-time startup costs, and project them for at least a year.
  • Cheap funding exists: SBA microloans run up to $50,000, and bootstrapping is a legitimate plan.
  • Launch small, get your first paying customers, and let their behavior set your next move.

Why now is a good time to open a business

People are filing. The Census Bureau counted 497,046 business applications in December 2025 (seasonally adjusted), and it projected about 30,438 of those would turn into businesses with payroll within four quarters. Read that gap carefully: lots of people apply, far fewer build employers. Filing is easy. Building something customers want is the hard part, and that is where this guide spends most of its time.

The SBA’s own guide splits the process into planning, launching and managing. We follow the same arc, with more opinion about what to do first.

Step 1: Pressure-test the idea

Your idea is a hypothesis. Treat it like one.

The SBA suggests asking yourself a handful of basic questions before you start: what you offer, what makes it different, and who your ideal customer is. If you can’t answer those in two sentences each, you are not ready to register anything.

Then go find evidence:

  • Talk to 10 to 15 people who fit your ideal customer. Ask about their last time they hit the problem, not whether they’d like your solution. Everyone is polite about ideas. Nobody lies about their calendar and credit card.
  • Look for people already paying to solve it, even badly. Existing spend is the best proof of demand.
  • Try a pre-sale, a waitlist or a paid pilot. A pound of signups beats an ounce of compliments.

Step 2: Research the market and competitors

Competition is good news. It means money is already moving. Your job is to find the gap: a segment ignored, a price point missing, a workflow that is miserable.

Map three to five alternatives, including the non-obvious ones (spreadsheets, agencies, “doing nothing”). For each, note who it serves, what it charges and what customers complain about. Write down the one sentence that explains why a buyer would switch to you.

Step 3: Write a lean plan

Skip the 40-page document. A plan you’ll actually reread covers the customer, the offer, pricing, how you’ll reach buyers, and the numbers. One to three pages is plenty unless a lender asks for more. If you are applying for a loan or pitching investors, expand it then.

Step 4: Calculate startup and ongoing costs

This is where first-timers get burned. The SBA notes that most entrepreneurs only add up one-time costs. Its startup cost guidance says to also project monthly expenses for at least a year, and ideally longer, so you can run a proper break-even analysis before launch.

A simple starter list:

  • One-time: state filing fees, licenses and permits, equipment, website, initial inventory, legal review if you want one.
  • Monthly: software, insurance, marketing, contractors, payment processing fees, your own minimum living costs.
  • Break-even: monthly costs divided by your profit per sale equals the number of sales you need each month.

SBA expert Marco Carbajo’s point on bootstrapping is worth keeping in mind: the aim isn’t always zero debt, it is assessing your costs before launch so you avoid expensive reactive borrowing later. For habits that keep the numbers honest, see our guide to tracking business expenses efficiently.

So, is $1,000 enough?

For some businesses, yes: a service business, a freelance practice or a simple online offer can start lean, since the main costs are filing fees, a basic site and your time. For inventory, equipment or a storefront, no. Run the cost list above for your specific model instead of trusting a generic number, including anyone’s, ours too.

Step 5: Decide how you’ll fund it

Your realistic options, from lowest risk to highest:

  1. Savings and early revenue (bootstrapping). Slow, but you keep control. Our guides on bootstrapping strategies for first-time founders and the pros and cons of bootstrapping walk through the trade-offs.
  2. SBA microloans. Per a March 2026 SBA update, microloans run from a few hundred dollars up to $50,000, average about $13,000, and carry interest generally between 8% and 13%. Intermediary lenders also provide guidance before and after you get the money, which the SBA’s Matt Coleman calls the main advantage over a traditional bank.
  3. Outside investment. Fine for some models, a bad fit for many. Read bootstrapping vs. fundraising before you take on a partner who owns part of your future.

Credit cards are the default for many new owners, and the interest can get ugly fast. Compare them against a microloan before you swipe.

Step 6: Choose a business structure

The IRS calls choosing a structure one of the most important first steps because it affects your tax filings, legal liability and regulatory obligations. Common options are sole proprietorship, partnership, LLC and corporation.

The short version: a sole proprietorship is the easiest and gives no separation between you and the business. An LLC or corporation adds a legal layer between your personal assets and the business, with more paperwork. Which one fits depends on your state, your risk and your tax picture. Before you file, our plain-language guide to choosing a business structure is a good primer, and a CPA or business attorney licensed in your state should confirm the final call, especially if you have partners or take on real liability.

Step 7: Name it and register it

Check that your name isn’t already taken in your state’s business registry, and that the matching domain and social handles are available. Then register with your state, usually through the Secretary of State’s office. States set their own fees and forms, so start on your state’s official site. The California Secretary of State, for instance, has a page walking through entity types and filings.

If you operate under a name other than your own legal name, you may also need a “doing business as” (DBA) registration, typically at the state or county level.

Step 8: Get your EIN, tax IDs and licenses

An Employer Identification Number works like a Social Security number for your business. The IRS says most businesses, including those without employees, typically need one, and you can get it free online in minutes. Never pay a third party for it.

Then work through the rest of the IRS checklist for starting a business, which stresses that it is a basic list and not all-inclusive. Add:

  • State tax registration: sales tax, if you sell taxable goods or services, and employer accounts if you hire.
  • Licenses and permits: these vary by industry, city and county. Search your city or county website for your trade.
  • Tax year: one trap from IRS Publication 583: you adopt a tax year only by filing your first return on that period. Getting an EIN or paying estimated tax doesn’t count, and changing later can need IRS approval.

Step 9: Separate your money and cover your risk

Open a business bank account so personal and business money never mingle. It makes bookkeeping bearable and, if you have an LLC or corporation, helps preserve the liability separation you filed for. Get business insurance suited to your work. Both are on the SBA’s launch list.

Keep records from day one. Publication 583 covers basic recordkeeping for new owners, and a simple spreadsheet beats a perfect system you never open.

Step 10: Launch small and chase traction

Launch is not a party. It is the start of your real market research. Sell to a handful of customers, watch what they do, and fix the biggest leak first. Pick one channel, run it for a few weeks, then measure. Our walkthrough on how to get traction for your startup lays out the first actions, and the list of startup mistakes to avoid will save you a few expensive lessons.

Our perspective: the paperwork is the easy part

Here is what we see over and over. Aspiring founders, especially the corporate employee with a good idea and a Sunday afternoon, spend weeks on the entity question and minutes on the customer question. It feels productive because forms have clear finish lines. Customer discovery doesn’t.

Our perspective: the paperwork is the easy part — overview diagram

We built siift around the opposite order. The hard, expensive mistakes come from untested assumptions, biases and blind spots, not from picking an LLC over an S corp. A generic chatbot will happily agree with your plan and hand you a confident-sounding answer. What a new founder needs is structure: the next question to ask, the next assumption to test, and a record of context so each decision builds on the last.

So our advice is boring and works: validate before you formalize, count monthly costs, keep the legal setup simple until revenue justifies more, and treat your first year as an experiment you can afford to lose. You don’t need permission, a cofounder or a pitch deck to begin. You need a clear next step.

FAQ

What is the very first step to opening a business?

Validate the idea with real potential customers. Describe the problem, ask how they handle it today and whether they’d pay to fix it. Formation paperwork can wait until you have evidence of demand.

Can I open a business with no money?

Yes, if the model is mostly your time: consulting, freelancing or a service. You still pay small costs such as state filing fees and possibly licenses, so list them first. If you need capital, the SBA microloan program offers loans from a few hundred dollars up to $50,000.

Do I need an LLC to start?

Not necessarily. You can start as a sole proprietor, but that leaves your personal assets exposed to business liabilities. Weigh your risk, state rules and taxes, and check with a CPA or attorney in your state.

Do I need an EIN?

Most likely. The IRS says most businesses typically need one, even without employees, and it is free to get online from the IRS.
