How to Buy a Business: Step-by-Step Guide (2026)

Buying an existing business is the fastest route into ownership — you skip the startup years and step into a company with customers, revenue, and cash flow from day one. It's also one of the largest financial commitments most people ever make, and the deals that go wrong almost always go wrong in the same places: weak due diligence, the wrong financing structure, or a purchase price the cash flow can't support.

This guide walks through the whole process, step by step, the way an advisor would walk a first-time buyer through it — from deciding what to buy, to financing the purchase, to what happens after you get the keys.

Step 1: Decide what kind of business to buy

Start with what you can actually run. Lenders will ask, and so should you: do you have experience in this industry, or something close to it? A buyer with ten years in restaurants buying a restaurant is a strong file. The same buyer purchasing a machine shop is a harder conversation.

Beyond fit, look for three things:

Consistent revenue. You want a business that earns money in ordinary years, not one that had one great year.
Verifiable cash flow. The numbers need to show up on tax returns and bank statements — not just in the seller's spreadsheet.
A reason the seller is leaving that makes sense. Retirement and burnout are normal. "The numbers are about to take off, trust me" is not.

Step 2: Understand how businesses are priced

Most small businesses sell for a multiple of their annual cash flow — usually SDE (seller's discretionary earnings) for owner-operated businesses, or EBITDA for larger ones. A common range is roughly 2–4x SDE for main-street businesses, though the multiple moves with industry, growth, and how dependent the business is on the current owner. We break down what drives that range in Small Business Valuation Multiples: What Drives the 2–4x SDE Price.

The question that matters most isn't the sticker price — it's whether the business's cash flow can cover the loan payments and still pay you. Lenders call this debt service coverage, and most want to see the business earning at least 1.25x its annual loan payments. If a deal only works when you assume revenue jumps 30% after you take over, it doesn't work.

Step 3: Line up your financing before you make an offer

Sellers take buyers with financing in place far more seriously. The three structures that fund most small business acquisitions:

SBA 7(a) loans. The most common way to finance an acquisition. Standard terms run up to 10 years for a business purchase (25 if real estate is included), with down payments typically around 10–20% and the SBA guaranteeing 75% of the loan for the bank. Rates are capped by the SBA and usually price at Prime plus a margin.
Seller financing. The seller carries part of the price as a note — often 10–30% of the deal. This lowers the bank loan, signals the seller believes in the business, and in many SBA deals can count toward your down payment if the note stands by (no payments) for 24 months.
Conventional acquisition loans. Faster and less paperwork than SBA, but usually shorter terms and higher down payments. Best for strong buyers or deals that don't fit SBA rules.

Most real deals blend two of these. A typical structure: 10–15% buyer cash, 10% seller note, and an SBA 7(a) loan for the rest. Run your own numbers with our SBA acquisition loan calculator — it models the bank loan, the SBA guarantee fee, and a seller note together so you can see the real monthly payment before you make an offer.

Step 4: Do real due diligence

Once you have a signed letter of intent, you typically get 30–60 days to verify everything — including that the cash flow supports the multiple you agreed to (see our valuation multiples guide). At minimum, review:

Three years of business tax returns and profit-and-loss statements
Twelve months of business bank statements — do deposits match the reported revenue?
Customer concentration — if one customer is 40% of revenue, that's a risk priced into the deal or a reason to walk
Leases, contracts, licenses, and any liens or pending lawsuits
Why employees stay or leave — key-person risk hides here

Have a CPA review the financials and an attorney review the purchase agreement. The cost of both is trivial next to the cost of buying a business with hidden problems.

Step 5: Close and plan the first 90 days

A standard SBA-funded acquisition closes in roughly 30–60 days from a complete application. Build a transition plan into the deal itself: most purchases include the seller staying on for a few weeks to a few months to introduce you to customers, vendors, and staff.

Then do the boring things well: keep the team stable, don't change pricing or branding in month one, and protect cash. The businesses that fail under new ownership usually weren't broken when they were bought — they were "improved" too fast.

Common mistakes to avoid

Paying for potential. Buy the business as it performs today. If the seller's growth story were certain, they'd stay.
Draining your reserves for the down payment. You need working capital after closing. A deal that leaves you with zero cash is undercapitalized from day one.
Skipping the seller note when it's offered. Seller financing is often the cheapest capital in the deal — and the strongest signal the seller trusts the numbers.
Rushing due diligence to "win" the deal. There is always another business for sale.

Getting started

If you've found a business — or you're still looking and want to know what you could qualify for — the fastest next step is a pre-qualification. It takes a few minutes, there's no hard credit pull, and you'll know your real budget before you make an offer.
