How to Start a Business Overnight: The Complete Checklist

Most people think starting a business takes months of planning, thousands of dollars, and a perfect moment that never arrives. It doesn't. If you have an idea tonight, you can have a legal business by the time you go to sleep.

This is the checklist — in order — of exactly what to do.

Before You Start: Get Clear on the Idea (30 minutes)

You don't need a business plan. You need one sentence: what you're selling, to whom, and why they'd pay for it. Write it down. If you can't write it in one sentence, keep thinking.

You also don't need a unique idea. You need an idea you can execute on — something you know how to do, or can learn quickly, and that someone will pay for this month.

• Freelance services — writing, design, development, video editing, bookkeeping
• Physical products you make or resell
• Digital products — templates, courses, guides
• Local services — landscaping, cleaning, delivery, tutoring
• Online services with a defined outcome — social media, SEO, ads management

Step 1: Name Your Business (15 minutes)

Your business name doesn't need to be perfect. It needs to be available and professional. Check your state's business entity database to confirm availability, and search for a matching .com domain.

Step 2: Form Your LLC (1 hour)

Filing an LLC is how you turn an idea into a legal business entity. Your personal assets get protected, you can open a business bank account, and you look legitimate to clients. The state filing fee ranges from $50 to $300 depending on your state. Online filings are typically processed within hours.

Step 3: Get Your EIN (10 minutes)

An EIN is your business's federal tax ID. Apply at IRS.gov — it's free, takes 10 minutes, and your number is issued immediately. You need it to open a business bank account and file business taxes.

Step 4: Open a Business Bank Account (20 minutes)

Never mix personal and business money. Open a free business checking account with Mercury — no fees, no minimums, opens online in minutes. You'll need your EIN and Articles of Organization.

Step 5: Get Online (30 minutes)

You don't need a custom website tonight. You need a presence. A one-page site with your name, what you do, and how to contact you is enough to send to your first leads. Buy your domain (~$12/year) and set up a business email.

Step 6: Tell 10 People (30 minutes)

Your first customers aren't strangers on the internet — they're people who already know you. Send 10 personal messages to people who could hire you or refer someone who would. Tell them what you're doing, what problem you solve, and ask if they know anyone who needs it.
