Your First 90 Days in Business: A Pre-Launch Checklist

Summary

24 items · 1–2 hours to review; ongoing execution over 90 days

Why the First 90 Days Define Your Business Foundation

Most new businesses don't fail because the idea was bad — they fail because the foundation wasn't solid before the doors opened. The first 90 days aren't just about selling; they're about building the structures that let your business survive and grow. If you're new to the entrepreneurial journey, the core concepts every aspiring entrepreneur needs are worth reviewing before you dive into this checklist.

This checklist covers the essential tasks across four categories: legal and structural setup, financial readiness, operations, and marketing. Work through each section systematically — don't skip steps because they feel administrative. Those "boring" tasks are exactly what protects your investment.

Business Structure Decisions Are Hard to Reverse

Your choice of legal structure — sole proprietorship, LLC, corporation — affects your personal liability, how profits are taxed, and your ability to bring in investors. Changing your structure after launch is possible but can be costly and complicated. Before registering, consult a licensed attorney or CPA who can assess your specific situation.

The Pre-Launch Checklist

The items below are organized by category. Each task is labeled by priority: must items are non-negotiable before launch, should items are strongly recommended, and nice-to-have items add meaningful value when resources allow.

Legal & Structural Setup

Choose a business structure (sole proprietorship, LLC, S-corp, etc.) based on your liability needs and tax situation — consult an attorney or CPA before deciding. Must

Obtain an Employer Identification Number (EIN) from the IRS, even if you have no employees — it's free and required for most banking and tax filings. Must

Apply for all required business licenses and permits at the local, state, and federal levels relevant to your industry. Must

Review your insurance needs with a licensed broker, including general liability, professional liability, and property coverage. Should

Draft or review any partner, contractor, or vendor agreements with a qualified attorney before signing. Should

Financial Readiness

Open a dedicated business checking account to keep all business transactions completely separate from personal finances. Must

Build a startup budget that projects your first six months of expenses, including fixed costs, variable costs, and a contingency reserve. Must

Set up basic accounting software or a bookkeeping system before your first transaction, not after. Must

Establish your pricing model and confirm it covers costs plus a sustainable margin — revisit it with actual data after 30 days. Must

Identify how you will accept payments from customers (invoicing, point-of-sale, online checkout) and test the system before launch. Should

Research whether you are required to collect and remit sales tax in your state and set up the process before your first sale. Should

Operations & Infrastructure

Secure your primary operating location — whether a lease, home office setup, or virtual address — and confirm it meets zoning requirements. Must

Document your core operating procedures, even informally, so key tasks can be performed consistently from day one. Should

Identify your supply chain or service delivery workflow and confirm you have at least one reliable backup supplier or partner. Should

Set up a professional business email address and basic communication tools separate from personal accounts. Should

Create a simple onboarding checklist for your first hire or contractor, even if you don't plan to hire immediately. Nice to have

Marketing & Customer Acquisition

Claim your Google Business Profile and verify your listing before launch so customers can find you from day one. Must

Publish a functional website that clearly communicates what you offer, who it's for, and how to buy or contact you. Must

Define your target customer clearly — demographics, problems they're solving, and where they spend time online. Must

Choose one or two social media platforms where your audience is most active and establish a consistent posting schedule. Should

Identify three to five ways you will generate your first customers and create a simple 30-day outreach plan. Should

Set up a basic email list and a method to collect subscriber addresses from your first website visitors. Nice to have

Don't Skip Permits and Licenses

Operating without required licenses or permits — even temporarily — can result in fines, forced closure, or personal liability. Requirements vary widely by industry, city, and state, so what applies to another business in your area may not apply to yours. Always verify requirements with your local government and a qualified professional before opening.

Once your business is up and running, your next major milestone is scaling responsibly. Use the operational readiness checklist for small business owners to assess whether your foundation can support growth before you expand.

Building Smart Financial Habits From Day One

The financial tasks in this checklist aren't one-time events — they set habits you'll rely on for years. Keeping business and personal finances completely separate is arguably the single most important early discipline. It simplifies taxes, makes your records audit-proof, and gives you a clear picture of actual business performance.

Tracking every expense and revenue source from the very first transaction is far easier than trying to reconstruct records months later. The essential financial concepts every small business owner needs hub is a useful ongoing reference as your financial complexity grows. If budgeting feels overwhelming at first, starting with practical strategies for tracking spending and building a workable budget can build your confidence before tackling business-specific finance.
