Forget the 40-page business plan. Here's the honest, minimal path from idea to your first paying customer — and the finance setup that keeps the IRS off your back.
Talk to 15–20 people in your target market before writing any code, printing any product, or building a website. You're not selling — you're listening for what they already pay for and hate about it.
Sole proprietorship is free but offers no liability protection. An LLC costs $50–$500 to file and separates your personal assets. Most new founders should form a single-member LLC in their home state.
Free, takes 10 minutes online at irs.gov. You need it to open a business bank account and hire anyone. Do this the same week you file your LLC.
Never mix personal and business money. It kills your liability protection and makes bookkeeping a nightmare. Most online banks (Mercury, Relay, Novo) open in a day with your EIN.
Track every dollar in and out. You don't need QuickBooks — a simple app like SnapBooks or even a spreadsheet works for the first year. The goal is a monthly P&L and a clean paper trail for taxes.
Warm outreach beats cold ads at this stage. Message 30 people who fit your ideal customer, ask about their problem, and offer to solve it. One paying customer teaches you more than a year of planning.
Move 25–30% of every payment to a separate savings account for taxes. Freelancers and business owners pay quarterly estimated taxes to the IRS — miss them and you get penalties.
Track income, expenses, invoices, and taxes from day one — in 15 minutes a week.
Start freeMost service businesses can start for under $500 — a domain, an LLC filing, a business bank account, and basic software. Product businesses need more for inventory. Don't confuse startup cost with runway: you also need 3–6 months of personal expenses saved before quitting a day job.
Start as a sole prop (nothing to file) or single-member LLC ($50–$500 depending on state) for liability protection. S-Corp only makes sense once net profit is consistently above ~$60k — it saves self-employment tax but adds payroll.
Depends on your city, state, and industry. Most online service businesses just need a state LLC filing and an EIN from the IRS (free). Regulated fields (food, childcare, contracting, health) need additional licenses.
Talk to 20 people in your target market before building anything. First customers almost always come from your existing network, warm outreach, or a specific niche community — not paid ads. If you can't get one person to pay, more marketing won't help.
Day one. Open a separate business bank account before your first sale, put every expense on a business card, and record income + expenses weekly. Waiting until tax season means recreating a year of memory from bank statements — painful and expensive.
