How to Buy a Small Business

How to Buy a Business: The Acquisition Entrepreneur's Complete Guide

A step-by-step framework for sourcing, evaluating, financing, and closing a small business acquisition — and structuring it to build long-term enterprise value.

‍What does it mean to buy a business?

Buying a business means acquiring an existing operating company — its assets, customer relationships, employees, systems, and cash flows — rather than building from scratch. Acquisitions are typically structured as either an asset purchase or a stock purchase, each with distinct tax and legal implications. Most small business acquisitions in the lower middle market ($500K–$10M enterprise value) are financed with a combination of SBA debt, seller financing, and buyer equity.

Why Acquisition Is the Fastest Path to Business Ownership

Building a business from zero means years of losses before profitability. Buying one means you acquire cash flow on day one. You inherit customers, staff, systems, and market position. You skip the startup mortality curve.

The lower middle market — businesses generating $1M to $10M in EBITDA, typically priced between $3M and $50M — is the most active acquisition segment in the U.S. It's also the most inefficient. Most sellers haven't prepared their financials for scrutiny. Most buyers don't know how to evaluate what they're looking at. That gap is where disciplined acquirers win.

This guide covers the complete acquisition process: how to source deals, evaluate them, structure financing, run diligence, and close — with specific attention to the tax and financial analysis decisions that determine whether you paid the right price.

Step 1: Define Your Acquisition Criteria Before You Start Looking

Most first-time buyers waste 12–18 months looking at deals that were never right for them. The fix is a written acquisition thesis before you contact a single broker or seller.

Your thesis should define:

•       Industry or vertical focus — and your specific reason for that focus

•       Revenue and EBITDA range (be realistic about your financing capacity)

•       Geography — are you buying to operate locally, or are you building a distributed holdco?

•       Business model requirements — recurring revenue, B2B vs. B2C, asset-light vs. capital-intensive

•       Owner dependency ceiling — how owner-dependent is too dependent?

•       Deal structure preferences — SBA vs. conventional, seller note tolerance, earnout appetite

The thesis isn't a filter for ruling things out — it's a compass for where to focus your energy. Buyers who can clearly articulate why they're buying what they're buying move faster, get taken more seriously by sellers and brokers, and make better decisions under the pressure of a live deal process.

The thesis as a competitive advantage

Sellers and their advisors see a lot of buyers. The buyer who says 'I'm building a regional platform in commercial HVAC because I spent 15 years in the industry and understand the service model' is a materially different counterparty than the buyer who says 'I'm looking at a wide variety of businesses.' Thesis clarity signals conviction, which signals execution certainty.

Step 2: Build Your Deal Flow Sources

The best acquisitions rarely appear on public listing sites. BizBuySell and similar platforms list mostly distressed sellers, retirement-driven exits, and businesses that couldn't sell through private channels. The deals worth buying come from relationships.

Broker Relationships

Business brokers and M&A advisors control access to most marketed deals in the lower middle market. Build a list of 15–20 brokers in your target industry and geography. Call each one. Explain your thesis. Ask to be added to their deal flow. Repeat quarterly. Brokers remember buyers who are credible, responsive, and don't waste their time.

Off-Market Sourcing

Off-market deals are acquired through direct outreach to owners who aren't actively selling. This requires a systematic approach: build a target list of businesses that match your thesis, identify the owner, and reach out with a credible, non-salesy letter or email explaining your interest. Response rates are low — expect 1–3% — but the deals you source this way are uncompeted and often priced more favorably.

Your personal brand as a buyer amplifies off-market sourcing. Owners who have seen your content, heard your thesis, or recognize your name are dramatically more likely to take a meeting. This is why building a visible presence in your target vertical before you need it is a compounding advantage.

Deal Platforms and Databases

Axial, DealStream, and Sutton Place Strategies each carry lower middle market deal flow that doesn't hit public platforms. Independent sponsor and search fund communities (ETA networks, Self-Funded Search community) are also high-signal sources. LinkedIn, targeted to owners of businesses in your criteria, is underutilized.

Step 3: Evaluate Deals — The First Screen

When a deal crosses your desk, you need a fast first screen before committing time to deeper diligence. The goal is to answer three questions quickly: Is this business real? Is the price range plausible? Is there a structural reason to proceed?

The CIM Review

Most marketed deals come with a Confidential Information Memorandum (CIM) — a seller-prepared document summarizing the business, its financials, and the opportunity. Treat a CIM as a marketing document, not a diligence document. The financials are presented in the best possible light. Add-backs are aggressive. Growth projections are optimistic.

What you're evaluating in the CIM: business model clarity, revenue composition, customer concentration, owner role, and whether the EBITDA being sold is plausible. If the CIM raises more questions than it answers, that's normal — you're supposed to have questions.

The Seller Call

Before submitting an LOI, you need at least one substantive call with the owner. What you're listening for: why they're selling (retirement vs. distress vs. boredom — each has different implications), how involved they are in the business, how they describe their customers and competition, and whether their answers match what's in the CIM.

Sellers who are vague about why they're selling, defensive about customer concentration, or unable to explain their add-backs clearly are red flags. The best sellers are transparent, organized, and have a clear, logical reason for the transaction.

First-screen kill criteria

Revenue or EBITDA outside your thesis range. Customer concentration above 40% in a single customer. Owner who is the primary relationship holder for all major accounts with no transition plan. Business in secular decline with no credible turnaround thesis. Asking multiple that implies zero room for diligence adjustments.

Step 4: The Letter of Intent

The Letter of Intent (LOI) is a non-binding indication of your intent to acquire the business at a specified price and under specified terms. It's the document that locks the seller into exclusivity with you while you complete diligence.

Key LOI Terms

•       Purchase price — stated as a specific dollar amount or as a formula tied to a multiple of trailing EBITDA

•       Deal structure — asset purchase vs. stock purchase (more on this below)

•       Financing contingencies — SBA loan approval, third-party financing conditions

•       Seller financing — amount, term, interest rate, subordination

•       Earnout provisions — if applicable, the metric, period, and calculation methodology

•       Working capital peg — the target working capital level at close, and how adjustments are handled

•       Exclusivity period — typically 45–90 days

•       Key employee retention — conditions for employees critical to the transition

The LOI is non-binding on price in the sense that diligence findings can and should adjust it. A business that presents $2M EBITDA in the CIM but delivers $1.4M after a quality of earnings analysis gets repriced. This is expected and normal — LOI price is based on seller representations, not verified financials.

Pricing the LOI

Lower middle market businesses typically trade at 3–6x EBITDA, with variation driven by growth rate, revenue quality, owner dependency, industry, and market conditions at time of sale. Asset-heavy businesses (manufacturing, equipment-intensive services) often trade at lower multiples. Software or recurring-revenue businesses trade higher.

Price the LOI at a multiple you can defend with post-diligence financials. Aggressive LOI pricing followed by a retrade after diligence damages the relationship and sometimes kills the deal. Better to price conservatively and explain your logic.

Step 5: Quality of Earnings — The Most Important Diligence Step

The Quality of Earnings (QofE) analysis is the financial backbone of your diligence process. It answers the foundational question every buyer must answer: Is the EBITDA I'm paying a multiple on actually real?

What is a Quality of Earnings analysis?

A Quality of Earnings report is a financial analysis performed by an independent CPA that reconstructs the target company's earnings from source documents — bank statements, tax returns, invoices, payroll records — and adjusts for one-time items, owner-specific expenses, non-recurring revenue, and accounting irregularities. The output is a verified, normalized EBITDA figure that reflects the economic earnings available to a new owner.

Why QofE Is Non-Negotiable for Serious Buyers

Sellers present add-backs — expenses they claim are non-recurring or owner-specific — that inflate the reported EBITDA. Some add-backs are legitimate: above-market owner compensation, personal vehicle expenses, discretionary travel, one-time professional fees. Others are not legitimate: revenue recognition pulled forward, expenses deferred to manage the trailing twelve months, related-party transactions priced below market.

Without a QofE, you're buying a multiple of a number you haven't verified. In a $3M purchase, a $300K EBITDA overstatement at a 5x multiple means you overpaid by $1.5M — more than enough to impair returns on the entire deal.

What a QofE Covers

•       Revenue quality — concentration, contract vs. transactional, one-time vs. recurring

•       Add-back verification — are owner's claimed adjustments legitimate and documentable?

•       Expense normalization — what does the cost structure look like under new ownership?

•       Working capital analysis — what is the normal working capital requirement, and is the peg appropriate?

•       Customer and contract review — what revenue is at risk post-close?

•       Accounting methodology review — is the business on accrual or cash basis, and what does the conversion look like?

When to Engage a QofE Provider

The QofE should be initiated immediately after LOI execution, during the exclusivity period. A full QofE typically takes 3–5 weeks for a lower middle market business. Budget $15,000–$40,000 depending on complexity and business size.

The QofE findings directly inform your final purchase price. If diligence surfaces a material EBITDA restatement, you renegotiate. If it confirms the seller's representations, you close with confidence. Either outcome is valuable.

Step 6: Financing the Acquisition

Most lower middle market acquisitions are financed with a combination of sources rather than a single instrument. Understanding the capital stack before you write an LOI determines what purchase price range is realistic for you.

SBA 7(a) Loans

The SBA 7(a) loan program is the dominant financing vehicle for acquisitions below $5M enterprise value. Key parameters: up to $5M in loan proceeds, 10-year term for business acquisition, current rates at prime plus 2.25–2.75% (variable). The SBA requires a 10% equity injection from the buyer — meaning a $3M acquisition requires $300K of buyer equity at minimum.

SBA loans require the business to demonstrate sufficient cash flow to service the debt. The debt service coverage ratio (DSCR) must typically exceed 1.25x — meaning every dollar of debt service requires $1.25 of EBITDA to cover it. Model this before you submit an LOI. A business with $500K EBITDA can support roughly $400K in annual debt service, which approximates $3.5–3.8M in SBA financing at current rates.

Seller Financing

Seller notes are a standard component of lower middle market deals. The seller lends a portion of the purchase price back to the buyer at a negotiated interest rate and term. Seller notes typically constitute 10–20% of the purchase price, are subordinated to senior debt, and may have a 2-year deferral on principal payments during the transition period.

Seller financing serves two functions: it closes the gap between what the SBA will lend and the purchase price, and it aligns seller incentives with a successful transition. A seller who holds a note on the business they just sold has an interest in making sure the buyer succeeds.

Conventional and Private Credit

For deals above $5M, or for buyers with existing cash flow who don't want SBA constraints, conventional bank debt and private credit are options. Conventional lending typically requires 20–30% equity, stronger personal financials, and often real estate collateral. Private credit funds operate in the $5M–$50M range and can move faster than banks with more flexible structures.

Building the Capital Stack

A well-structured acquisition capital stack for a $4M purchase price at current rates might look like: $3.2M SBA 7(a) loan, $400K seller note (10% of purchase price), $400K buyer equity. The SBA loan services at approximately $400K annually. The seller note defers for 24 months, then services at approximately $55K annually. The business needs to generate at least $575K in EBITDA to cover combined debt service at 1.25x DSCR.

Step 7: Tax Structuring — Asset Purchase vs. Stock Purchase

The tax structure of a business acquisition is one of the highest-leverage decisions in the entire process. Done correctly, it can create $500K–$2M+ in present value tax savings on a single transaction. Done incorrectly, it creates a tax liability that impairs returns for years.

Asset Purchase

In an asset purchase, the buyer acquires specific assets of the business — equipment, intellectual property, customer contracts, inventory, goodwill — rather than the legal entity. The buyer receives a stepped-up tax basis in all acquired assets equal to the purchase price allocation. This is the buyer-preferred structure because it generates depreciation and amortization deductions against future earnings.

Under Section 1060 of the Internal Revenue Code, purchase price is allocated across asset classes in a specific sequence. Tangible assets (equipment, vehicles, inventory) are allocated first at fair market value. The residual — typically the largest component — is allocated to intangibles and goodwill, which amortize over 15 years under Section 197.

Stock Purchase

In a stock purchase, the buyer acquires ownership of the legal entity itself — all its assets and liabilities, known and unknown. The buyer inherits the seller's historical tax basis in the assets, which is typically much lower than the purchase price. This means no step-up, no fresh depreciation schedule, and significantly higher effective tax cost over the hold period.

Sellers prefer stock sales because they recognize gain at capital gains rates rather than ordinary income rates, and they transfer all known and unknown liabilities to the buyer. Buyers typically require a price discount to accept a stock structure, or negotiate a Section 338(h)(10) election.

Section 338(h)(10) Elections

For S-corporation acquisitions, the parties can jointly elect under Section 338(h)(10) to treat a stock purchase as an asset purchase for tax purposes. The buyer gets the step-up in basis they want; the seller recognizes a single level of gain taxed at capital gains rates. It's a negotiated structure that often bridges the buyer-seller preference gap on deal structure.

The tax structuring decision should happen before the LOI

Experienced M&A advisors structure the deal before they price it. The asset vs. stock decision, the purchase price allocation across asset classes, the treatment of goodwill and customer intangibles — these choices have direct cash flow implications for the first 5 years of ownership. Engage a qualified M&A tax advisor at the LOI stage, not at closing.

Step 8: Closing and the First 90 Days

Closing is the execution of the purchase agreement and transfer of ownership. Key closing mechanics include: final working capital true-up against the agreed peg, confirmation that all representations and warranties are accurate as of close, escrow arrangements, and transition services agreements.

Working Capital True-Up

The working capital peg is one of the most contested elements of lower middle market deals at closing. The peg defines the level of working capital (current assets minus current liabilities) that should be in the business at close. If actual working capital is below the peg, the seller owes the buyer a dollar-for-dollar adjustment. If above, the buyer pays the seller.

Sellers have incentive to drain working capital before close — collecting receivables aggressively, deferring payables, reducing inventory. Buyers need to monitor working capital during the exclusivity period and include a working capital lockbox or monitoring covenant in the purchase agreement.

The First 90 Days

The 90 days post-close are the highest-risk period of any acquisition. Key priorities: retain key employees, maintain customer relationships, understand cash cycle, and avoid making major operational changes before you understand the business.

The financial operations priority in the first 90 days is establishing clean reporting. If you acquired a business running on cash-basis QuickBooks maintained by the owner's spouse, the first order of business is converting to accrual accounting, establishing a proper chart of accounts, and building visibility into the actual P&L and cash position.

Buy-and-Build: Acquiring Multiple Businesses to Build Platform Value

A single acquisition is a business. Multiple acquisitions of complementary businesses — a platform with add-ons — is an enterprise. The distinction matters because enterprise value compounds differently than individual business value.

The buy-and-build model works on multiple arbitrage: you acquire businesses at 3–5x EBITDA, consolidate them onto a shared infrastructure, and exit the platform at 7–12x. The EBITDA growth from add-ons, combined with the multiple expansion from platform size, is the return driver.

For the buy-and-build to work, the platform acquisition needs to be financially clean from day one. That means proper management accounting, normalized EBITDA tracking across entities, and a capital structure that can support additional acquisitions without over-leveraging the platform. This is where having embedded financial infrastructure — not just a bookkeeper, but controller-level oversight of the consolidated financials — is the difference between a platform that can raise capital for the next acquisition and one that can't.

Frequently Asked Questions

How much money do I need to buy a business?

For an SBA-financed acquisition, the minimum equity injection is 10% of the purchase price. A $3M acquisition requires $300K of buyer equity. Additionally, budget $25,000–$60,000 for professional fees (legal, QofE, accounting, lender fees). Effective all-in capital required for a $3M acquisition is typically $350,000–$400,000.

How long does it take to buy a business?

From first contact with a target to closing typically takes 4–9 months. The LOI phase (negotiation through execution) is 2–4 weeks. Exclusivity and diligence is 60–90 days. SBA loan approval runs 60–90 days concurrently. Legal documentation and closing takes 2–4 weeks. Deals with complex structures, real estate, or SBA complications take longer.

What is a quality of earnings report and do I need one?

A quality of earnings report is an independent CPA's analysis of the target company's financial statements, verifying that reported EBITDA accurately reflects the economics of the business. For any acquisition above $500,000 in purchase price, a QofE is not optional — it is the primary protection against overpaying for misrepresented earnings. Cost ranges from $12,000 to $40,000 depending on complexity.

Is it better to do an asset purchase or stock purchase?

Asset purchases are generally preferred by buyers because they provide a stepped-up tax basis, generate depreciation deductions, and exclude unknown liabilities. Stock purchases are preferred by sellers because they convert all gain to capital gains rates. The right structure depends on the specific deal, entity type, and negotiation. For S-corporation acquisitions, a Section 338(h)(10) election can provide both parties with their preferred tax treatment.

What is seller financing and should I ask for it?

Seller financing is a loan from the seller to the buyer representing a portion of the purchase price, typically 10–20% of deal value. It is standard in lower middle market acquisitions and serves as a gap-filler between SBA proceeds and purchase price. Asking for seller financing is not a sign of weakness — it aligns seller incentives and signals to the seller that you expect the business to perform post-close.

What industries are best for first-time acquisition buyers?

Service businesses with recurring or repeat-purchase revenue, low capital expenditure requirements, and multiple employees (not owner-dependent) make the best targets for first-time buyers. Commercial HVAC, landscaping, specialty trucking, accounting practices, physical therapy practices, and specialty distribution are commonly cited. The best industry is the one you understand well enough to evaluate the business accurately and add operational value post-close.

How do I find businesses for sale that aren't on public listing sites?

Off-market deals are sourced through business broker relationships, direct outreach to business owners, accountant and attorney referrals, industry association networks, and targeted LinkedIn prospecting. Building a visible personal brand in your target vertical is the highest-leverage long-term source — sellers call buyers they already know and trust before engaging a broker.

What is a working capital peg?

The working capital peg is the agreed-upon level of working capital (current assets minus current liabilities) that should be in the business at closing. It protects the buyer from sellers who drain cash or receivables before close. If actual working capital at close is below the peg, the seller pays the buyer the difference. If above, the buyer pays the seller. Peg levels are established during LOI negotiation based on the business's historical average working capital.

Do I need an M&A attorney to buy a business?

Yes. The purchase agreement for even a simple lower middle market acquisition runs 40–80 pages and contains representations, warranties, indemnification provisions, and post-close adjustment mechanisms that have material economic value. An experienced M&A attorney (not a general business attorney) who has closed comparable transactions is non-negotiable. Budget $15,000–$40,000 for buyer-side legal fees.

What is the role of a CPA in a business acquisition?

A qualified CPA with M&A experience fills multiple roles in an acquisition: performing or reviewing the quality of earnings analysis, advising on deal structure (asset vs. stock, purchase price allocation, earnout mechanics), modeling the tax implications of the transaction and the first 3–5 years of ownership, and establishing the financial infrastructure needed post-close. Buyers who engage an M&A-focused CPA at the LOI stage — not at closing — consistently structure better deals and avoid the tax inefficiencies that impair returns.
