How to Buy a Business: A Step-by-Step Guide [2026]

Why Buying an Existing Business Beats Starting From Scratch

Buying an existing business means acquiring revenue, customers, trained employees, supplier relationships, and proven systems on day one. A startup has to build every one of those assets from nothing, and most of the risk in a new company sits in that unproven first stretch: finding customers, setting prices, hiring the right people, and learning whether the market wants the product at all. An acquisition skips that phase entirely. You take over a machine that already works and your job becomes running and improving it, not inventing it.

The second advantage is financing. Banks rarely lend against an idea, but they routinely lend against historical cash flow. Because an established business has tax returns and financial statements that document its earnings, a buyer can borrow most of the purchase price through an SBA-guaranteed loan and repay it out of the profits the business already generates. This leverage is what makes acquisition accessible: a buyer with $100,000 to $200,000 in savings can realistically purchase a company worth $1 million.

The trade-off is price and complexity. You pay for the de-risked cash flow (a multiple of earnings rather than the cost of equipment and a lease deposit), and you inherit whatever problems the seller leaves behind. That is why the rest of this guide focuses on screening, valuation, and due diligence: the process exists to make sure the machine you are buying actually works the way the listing claims.

Define Your Acquisition Criteria First

Buyers who browse listings without criteria waste months chasing deals they were never going to close. Before you search, write down four constraints. First, your budget: the cash you can commit as a down payment plus reserves, which at typical SBA leverage of 10 to 20 percent down defines your realistic purchase price ceiling. Second, your skills: a business you understand operationally is worth more in your hands and far easier to diligence. Third, geography: owner-operated businesses generally require you to be physically present, especially in the first year. Fourth, your income requirement: the business's earnings must cover the loan payments and still pay you a living wage.

A useful screening formula: take the asking price, estimate the annual debt service on the financed portion, and subtract it from the seller's discretionary earnings. What remains is your pre-tax income as the new owner-operator. If that number does not comfortably exceed what you could earn as an employee, the deal needs a lower price, better terms, or a pass.

Where to Find Businesses for Sale

Online marketplaces are the widest funnel. BizBuySell, BizQuest, and similar platforms list thousands of small businesses across every industry and price range, searchable by location, sector, and cash flow. Marketplaces are ideal for calibrating: even before you are ready to make offers, reviewing listings teaches you what businesses in your target sector earn and what sellers ask for them.

Business brokers represent sellers, but serious buyers benefit from broker relationships too. Brokers see deals before they hit the public marketplaces and will call qualified buyers first when a fitting listing arrives. Introduce yourself to brokers active in your target industry and region, share your criteria and proof of funds, and stay in touch. If you want help identifying credible intermediaries, you can connect with a business broker through our matching service.

Off-market outreach is the highest-effort, highest-reward channel. Many owners would sell to the right buyer but have never listed. Direct letters or calls to owners in your target industry, and conversations with accountants, attorneys, and industry association contacts who know which owners are approaching retirement, can surface businesses with no competing bidders. Off-market deals often price more reasonably precisely because there is no auction.

How to Screen Listings and Spot a Real Opportunity

Expect to review dozens of listings for every one that deserves a meeting. Screen fast using three filters. Earnings quality: does the listing state SDE or cash flow clearly, and is the asking price a sane multiple of it? Listings priced far above the normal range for the sector are usually anchored to the seller's retirement needs, not the market. Trend: flat or growing revenue over three years is workable; a steep decline means you are buying a turnaround, which deserves a much lower price. Transferability: if the business is the owner (a consultant with personal relationships, a contractor whose license holds the company together), the earnings may walk out the door at closing.

Watch for inflated add-backs. Sellers normalize their earnings by adding back personal expenses and one-time costs to produce the SDE figure, and aggressive brokers stretch this. An add-back schedule that doubles the reported profit deserves line-by-line scrutiny during due diligence. Also note the lease: a great business with two years left on a below-market lease in a location-dependent industry carries hidden risk the listing will not mention.

When a listing passes the screen, sign the non-disclosure agreement, request the confidential information memorandum and three years of financials, and schedule a call with the broker or owner. Your goal at this stage is not to negotiate; it is to disqualify quickly so you can spend real attention on the few businesses that merit it.

How to Value a Business Before You Buy

The asking price is the seller's opinion. Your offer should rest on your own valuation, built the same way brokers and appraisers build theirs: a normalized earnings figure multiplied by an industry-calibrated multiple. For owner-operated businesses, the standard metric is seller's discretionary earnings, and small businesses typically sell for 1.5x to 4x SDE. Larger companies with professional management are valued on earnings before interest, taxes, depreciation, and amortization (EBITDA) instead, at higher multiples applied to a smaller earnings base. Our guide to how valuation multiples work explains what pushes a specific business toward the top or bottom of its range.

Recalculate the earnings yourself. Start from the tax returns (not the profit-and-loss statement the seller prepared for the sale), verify each add-back with documentation, and rebuild the SDE from the bottom up. Then apply the multiple range for the industry, adjusting downward for customer concentration, owner dependency, declining revenue, or thin records, and upward for recurring revenue, a strong team, and multi-year growth. Run the target's numbers through our free business valuation calculator to get a three-method estimate you can hold against the asking price.

Valuation also protects your financing. If you agree to pay more than an independent valuation supports, the SBA lender's required third-party valuation can come in below your contract price and force a renegotiation late in the process. Anchoring your offer to defensible math from the start avoids that collision. For the underlying methodology, see our explanation of how business valuation works.

Financing the Purchase: SBA 7(a) Loans and Seller Notes

The Small Business Administration (SBA) 7(a) program is the workhorse of small business acquisition financing. Loans run up to $5 million, terms of 10 years are typical for business purchases, and buyers usually put down 10 to 20 percent of the total project cost. The government guarantee lets banks lend against the business's cash flow rather than hard collateral, which is what makes leveraged purchases of service businesses possible at all. Model your payment and total interest with our SBA loan calculator, or compare conventional terms with the business loan calculator.

Seller financing is the second pillar. In many small business sales the seller carries a note for part of the price, commonly anywhere from 10 to 60 percent, repaid over 5 to 10 years at interest rates that typically run 6 to 10 percent. A seller note aligns incentives (the seller only gets fully paid if the business keeps performing), fills the gap between your down payment and the bank loan, and signals the seller's own confidence in the earnings. Use the seller financing calculator to model the note alongside your bank debt.

Whatever the stack, the lender's test is the debt service coverage ratio (DSCR): the business's annual cash flow divided by the annual loan payments. Lenders want 1.25x or better, meaning at least 25 percent more cash flow than debt service. Check any deal you are considering with the debt service coverage ratio calculator before you write the offer; if the deal cannot clear 1.25x at the asking price, the price is the problem.

The Letter of Intent to Buy a Business

Once you and the seller agree on the outline of a deal, you formalize it in a letter of intent (LOI): a short, mostly non-binding document stating the proposed price, deal structure (asset or stock purchase), financing contingencies, what is included in the sale (inventory, equipment, working capital), the due diligence period, and the target closing date. The LOI is not the final contract; its job is to lock the key economics before both sides spend serious money on lawyers, accountants, and loan applications.

Two provisions of the letter of intent are typically binding and matter greatly. Exclusivity gives you 30 to 90 days during which the seller cannot negotiate with other buyers, protecting the money you are about to spend on due diligence. Confidentiality binds both sides on the deal terms. Negotiate exclusivity long enough to complete diligence and financing; running out of exclusivity mid-process hands leverage back to the seller.

Keep the LOI specific on economics and light on legalese. Price, structure, seller note terms, what happens to key employees, and the seller's post-closing training commitment belong in it. Vague LOIs cause renegotiation later, and renegotiation after weeks of diligence is where deals die.

Due Diligence When Buying a Business

Due diligence is your organized verification of everything the seller has claimed, and it typically runs 30 to 60 days after the LOI is signed. Financial diligence comes first: reconcile the profit-and-loss statements against federal tax returns and bank deposits, verify every add-back in the SDE calculation, review accounts receivable aging, and confirm revenue is not concentrated in a handful of customers.

Legal and operational diligence covers the rest of the checklist: the lease and its assignability, customer and supplier contracts, employee agreements and any key-person risk, licenses and permits and whether they transfer, pending or threatened litigation, liens against the assets, equipment condition and maintenance records, and the state of any software or intellectual property the business depends on. Hire an accountant for the financial work and an attorney for the legal work; their fees are trivial next to the cost of a missed liability.

Diligence findings feed back into the deal. Small issues become closing conditions or price adjustments. Large discrepancies between the claimed and verified earnings justify retrading the price or walking away, and a buyer who has done disciplined diligence can do either with confidence. The worst outcome is discovering the problem after closing, when it is fully yours.

Questions to Ask When Buying a Business

The seller's answers in early conversations shape everything that follows, and evasive answers are themselves data. Ask these directly, ideally before the LOI:

• Why are you selling, and why now?
• How much of the revenue comes from your top five customers?
• What do you personally do each week that no employee can do?
• Which employees are critical, and do they know the business is for sale?
• Walk me through your add-back schedule. What documentation supports each item?
• What happened in any year where revenue dipped?
• Are there contracts, licenses, or permits that cannot be transferred to a new owner?
• What would you invest in first if you were keeping the business?
• Has the business ever been through a lawsuit, audit, or regulatory action?
• What does the competitive landscape look like, and who is gaining ground?
• Will you stay through a transition period, and for how long?
• Would you consider financing part of the purchase price?

The last question doubles as a test: a seller who refuses any seller financing on a business they claim is healthy is telling you something about their own confidence in its future.

Closing the Deal

Closing converts the LOI into binding contracts. The core document is the definitive purchase agreement, which sets the final price, the assets or shares being transferred, the representations and warranties the seller makes about the business, and the indemnification terms if those representations turn out to be false. Supporting documents include the bill of sale, assignments of the lease and contracts, the seller's non-compete agreement, the promissory note for any seller financing, and a transition services agreement covering the seller's post-closing involvement.

Most small business purchases are structured as asset sales, in which you buy the assets and goodwill through a new entity and leave the seller's legal entity (and its unknown liabilities) behind. Stock sales appear when the business holds non-assignable contracts or licenses that must stay with the entity. The structure has significant tax consequences for both sides, so settle it in the LOI, not at the closing table.

Funds typically flow through an escrow agent who confirms lien releases, prorations, and payoffs before releasing money to the seller. Coordinate the closing date with your lender, landlord consent, license transfers, and insurance so that you legally control everything the business needs on the morning of day one.

The Transition: Your First 90 Days as Owner

Most deals include a transition period of 30 to 90 days in which the seller trains you, introduces you to key customers and suppliers, and transfers the operational knowledge that never made it into a manual. Use it deliberately: shadow the seller through a full billing cycle, sit in on customer conversations, and document every process you see. Some buyers extend the arrangement with a consulting agreement for 6 to 12 months, which is especially valuable in relationship-driven businesses.

Your first priority is retention, not improvement. Employees and customers are watching to see whether the new owner will destabilize what they rely on. Meet every employee individually in the first week, reassure key customers personally, and keep compensation, service, and quality unchanged while you learn. The improvements you have planned will land better in month four than in week one.

Finally, keep score. Track revenue, margins, and cash weekly against the diligence numbers so you spot any post-closing slippage early, and revisit your valuation annually. The playbook that made you a disciplined buyer (verified earnings, honest multiples, clean records) is the same playbook that will one day make this business easy to sell.
