Buying a Business, Start to Finish

Buying an existing business means acquiring something that already works: proven cash flow, a customer base, trained employees, established vendors, and systems that generate revenue on day one. Compared with starting from scratch, you are buying down risk — roughly four out of five acquired businesses are still operating years later, while most startups fail.

The process, however, is unforgiving of shortcuts. Buyers who succeed treat it as a disciplined sequence: define what you are looking for, get your financing lined up, source real deals, value them correctly, make a smart offer, verify everything in due diligence, fund the purchase, and transition ownership carefully. This guide walks through each step the way I walk buyers through it in practice.

Why Buy Instead of Start?

The case for acquisition over a startup comes down to existing cash flow. A startup burns money for months or years before it turns a profit, if it ever does. An established business pays you from the first month — and, critically, that cash flow is what lets a bank lend against the purchase. You cannot get an SBA acquisition loan to fund a business plan on a napkin, but you can borrow the majority of the purchase price of a profitable business with a track record.

Acquisition also comes with people and process already in place: employees who know the work, customers who already buy, and a brand that already has a reputation. Your job shifts from inventing a business to running and improving one — a very different and generally more reliable path to ownership. This is the core idea behind Entrepreneurship Through Acquisition (ETA), the strategy of building wealth by buying rather than building.

Step 1: Define Your Acquisition Criteria

Serious buyers start with a written "buy box" — the specific profile of business they are looking for. Vague buyers ("I'll know it when I see it") waste months and lose out to prepared ones. Your criteria should cover:

• Industry and business type — what you understand, can manage, or genuinely want to operate
• Size — a target range for revenue and, more importantly, Seller's Discretionary Earnings (SDE) or EBITDA
• Price range — anchored to how much you can actually finance (see Step 2)
• Location — how far you are willing to operate from, and whether you will run it yourself or semi-absentee
• Deal characteristics — owner willing to train and transition, real estate available, recurring revenue, low customer concentration

Clear criteria do two things: they let brokers and sellers take you seriously, and they let you say "no" quickly to the 90% of listings that are not a fit, so you can focus on the ones that are.

Step 2: Get Your Financing in Order

Before you fall in love with a listing, know what you can buy. Most acquisitions of small and lower-middle-market businesses are financed with an SBA 7(a) loan, which can fund the majority of the purchase price, with the buyer typically bringing a down payment of around 10% (sometimes with a portion covered by a seller note on standby). The rest is amortized over up to ten years.

Getting pre-qualified with an SBA lender before you shop tells you your realistic price ceiling and signals to sellers that you can actually close. Beyond the down payment, budget for working capital, closing costs, and a personal cash reserve — running out of cash right after closing is a classic, avoidable mistake. See how much money you need to buy a business for the full breakdown, and understanding seller financing for how a seller note can reduce your cash outlay.

Step 3: Find Businesses for Sale

Deal flow comes from several channels, and good buyers work more than one:

• Business brokers — the primary source of vetted, on-market listings with prepared financials; building relationships with brokers in your target market puts you first in line
• Online marketplaces — BizBuySell and similar sites aggregate listings, though the best deals often move before they gain traction
• Off-market / direct outreach — approaching owners directly, or through your network, accountants, and attorneys, to find sellers before they list
• Industry and personal networks — many deals happen quietly through word of mouth

Expect to review many businesses for every one you pursue. Volume is normal — the discipline is in quickly screening against your criteria and spending real time only on the genuine fits.

Step 4: Evaluate and Value the Business

When a business clears your initial screen, you evaluate it seriously. Most small businesses are valued on a multiple of SDE; larger ones on EBITDA. A typical small business trades for roughly 2x to 4x SDE, with the multiple driven by recurring revenue, owner dependency, customer concentration, growth trend, and the cleanliness of the financials. (Our industry valuation guides show how these multiples vary by business type.)

At this stage you review the seller's financials — profit and loss statements, tax returns, and the add-backs that build SDE — and you ask the questions that reveal how the business really runs: How dependent is it on the owner? Why are they selling? How concentrated are the customers? What is the trend? The goal is to form a supportable view of what the business is worth to you, and whether the asking price leaves room for a fair deal.

Step 5: Make an Offer (the Letter of Intent)

Once you are confident enough to move forward, you submit a Letter of Intent (LOI) — a mostly non-binding document that lays out the proposed price, structure (asset vs. stock sale), deal terms, financing contingency, training and transition period, and an exclusivity window during which the seller stops shopping the business while you complete due diligence.

A well-crafted LOI protects both sides: it aligns expectations before either party spends serious money on diligence and legal work, and it sets the framework for the definitive purchase agreement. Price matters, but so does structure — how the purchase price is allocated, what the seller finances, the non-compete, and the transition all shape the real value of the deal.

Step 6: Perform Due Diligence

Due diligence is where you verify that the business is what the seller represented. This is the most important protection a buyer has, and it is exhaustive by design. You and your advisors examine:

• Financial — do the tax returns, bank statements, and P&Ls reconcile? Are the add-backs legitimate? Is the revenue real and collectible?
• Legal — entity standing, contracts, leases, licenses, litigation, and liabilities
• Operational — customer concentration, supplier relationships, employees, and how much runs through the owner personally
• The lease and any real estate — can it be assigned, and on what terms?

Problems found in diligence do not automatically end a deal — often they lead to a renegotiated price, an escrow holdback, or specific protections in the purchase agreement. But diligence is also when you should be willing to walk away if something material does not hold up. A disciplined buyer treats "no" as an acceptable and sometimes necessary answer.

Step 7: Secure Financing

With diligence underway, your financing moves from pre-qualification to formal approval. For an SBA-financed acquisition, the lender orders a third-party business valuation, reviews the financials and your background, and underwrites the deal. This is a real gate: the loan must make sense to the bank, which means the business has to support the debt service out of its cash flow.

Financing is frequently a stack: an SBA loan for the bulk of the price, a seller note for a portion (which also keeps the seller invested in a smooth transition), and your down payment. Structuring this well — and keeping the lender, seller, escrow, and attorneys moving in sync — is a large part of what determines whether a deal closes on time.

Step 8: Close the Deal

Closing is the coordinated finish: the definitive purchase agreement is signed, financing funds, the lease and key contracts are assigned, licenses are transferred, funds move through escrow, and ownership legally changes hands. In an asset sale — the most common structure for small-business acquisitions — you typically buy the assets and goodwill while the seller retains the legal entity and pre-closing liabilities.

A well-run closing is anticlimactic precisely because the hard work happened earlier. The documents, allocations, prorations, and approvals were all lined up during diligence and financing, so closing day is mostly signatures and wires. Wire-fraud precautions matter here: confirm all wiring instructions verbally through known contacts before sending funds.

Step 9: Transition and Take Over

The deal is not truly successful until the business survives the handoff. A defined transition period — often 2 to 12 weeks of the seller's active involvement, sometimes followed by a consulting arrangement — is where you learn the operation, get introduced to key customers and employees, and absorb the undocumented knowledge that makes the business run.

The first 90 days set the tone. Reassure employees, hold key relationships steady, and resist the urge to change everything at once. You bought the business because it worked; understand why it works before you start improving it. The buyers who build real wealth are the ones who stabilize first and optimize second.

What It Costs and How Long It Takes

Cash required: for an SBA-financed deal, plan on roughly a 10% down payment plus closing costs, working capital, and a personal reserve. On a $1,000,000 business, that often means $100,000+ down and additional cash on hand — see how much money you need to buy a business for a full breakdown.

Timeline: from serious search to closing typically runs six months to a year or more — often months of searching, then roughly 60 to 120 days from accepted LOI to close once you find the right business, driven largely by SBA underwriting and diligence. Patience is a competitive advantage; rushing is how buyers overpay or miss red flags.

Common Mistakes to Avoid

• Shopping without financing lined up — you lose good deals to prepared buyers
• Falling in love with a business and talking yourself past red flags
• Underestimating owner dependency — if the business is the seller, you are buying a job with debt attached
• Skimping on due diligence or on experienced advisors (broker, CPA, attorney)
• Running out of cash after closing by leaving no working-capital cushion
• Changing everything on day one and destabilizing the business you just paid for
