Where to Find Businesses for Sale
The best deals often don’t come from the places you’d expect. Here’s where to look, ranked roughly by quality:
M&A advisors and brokers.
The highest-quality deal flow comes through advisors who represent sellers. These businesses have been vetted, valued, and prepared for sale. The CIM (Confidential Information Memorandum) gives you the information you need to evaluate before you invest significant time.
Your professional network.
CPAs, attorneys, wealth advisors, and industry contacts often know of businesses that are quietly exploring a sale before they go to market. The best acquisitions often happen before a formal process begins.
Online marketplaces.
BizBuySell, BusinessesForSale.com, and similar platforms list thousands of businesses. The quality varies enormously — many listings are overpriced, poorly prepared, or stale. But for volume and early-stage browsing, they’re a reasonable starting point.
Direct outreach.
Some buyers — particularly search funders and acquisition entrepreneurs — identify target industries and geographies, then contact business owners directly. This is a numbers game, but it can surface opportunities that aren’t on the market.
3. Evaluating a Business: What to Look For Before You Offer
Not every business for sale is worth buying. Before you spend weeks on due diligence, you need a quick evaluation framework to separate real opportunities from time wasters.
The Five-Minute Filter
Does it make money?
This sounds obvious, but many listed businesses are unprofitable or barely breaking even. Look for businesses with clear, documented SDE or EBITDA.
Can it run without the current owner?
If the owner IS the business — they hold every customer relationship, make every decision, perform the core service — you’re buying a job, and a risky one at that. The best acquisitions have some management infrastructure in place.
Is the asking price defensible?
A business asking 6x SDE with flat growth and no recurring revenue isn’t a deal — it’s a wish. Compare the asking price to market multiples for the industry and size. Our EBITDA multiples by industry guide is a good reference.
Why is the owner selling?
Retirement and burnout are legitimate. “I want to pursue other opportunities” with a business that’s declining is a red flag. The seller’s motivation tells you a lot about the timeline and negotiation dynamics.
Does it fit your skills and resources?
The best acquisition is one where you can add value. If you have no experience in the industry and no operational expertise, the learning curve may be steeper than the opportunity justifies.
Going Deeper: The CIM Review
Financial trends.
Is revenue growing, flat, or declining? Are margins improving or compressing? Look at three years minimum. One great year surrounded by mediocre ones is not a growth story.
Customer concentration.
If one customer represents more than 20% of revenue, that’s a risk. If they represent more than 40%, it’s a deal-breaker for many buyers and lenders.
Revenue quality.
Recurring and contractual revenue is worth more than project-based or one-time revenue. Ask what percentage is recurring and what the churn rate is.
The team.
Who stays and who goes? What does the org chart look like? Are key employees likely to leave after a transition?
The competitive landscape.
Is the business differentiated, or is it competing on price in a commoditized market?
4. Financing the Deal: How Buyers Pay
SBA Loans: The Most Common Path
Seller Financing
In many lower middle market deals, the seller finances a portion of the purchase price — typically 10–30%. This means you pay the seller over time, usually at a negotiated interest rate over 3–5 years. Seller financing is common, expected, and actually works in the buyer’s favor: if the seller is willing to carry a note, it signals confidence that the business will continue to perform. For a deeper dive, see our guide on how seller financing works.

Cons
Due diligence is where you verify that what the seller told you — and what the CIM presented — is actually true. It's the most critical phase of the acquisition process. Skip it or do it poorly, and you're buying blind.
Financial Due Diligence
The most common structure in SBA deals: 10% buyer equity, 80% SBA loan, 10% seller note. The seller note shows commitment and often satisfies the bank’s requirement that the seller has skin in the game post-close.
Tax returns (3 years). Compare to the P&L the seller provided. Discrepancies aren’t always sinister, but they need explanation.
Bank statements. Verify revenue deposits match reported revenue. Look for unusual patterns.
Accounts receivable and payable aging. Old AR may be uncollectible. Large AP may signal cash flow problems.
Normalized earnings. Re-calculate SDE or EBITDA yourself. Verify every add-back the seller claimed.
Working capital. Understand the seasonal cash needs and what level of working capital transfers with the deal.
Legal Due Diligence
Contracts and agreements. Customer contracts, vendor agreements, leases, employment agreements. Are they assignable? Do any have change-of-control provisions?
Litigation history. Any pending or threatened lawsuits? Any past settlements that could signal ongoing risk?
IP and licensing. Trademarks, patents, trade secrets, software licenses. Make sure the business actually owns what it claims to own.
Regulatory compliance. Industry-specific licenses, permits, environmental compliance. Ensure everything is current and transferable.
Operational Due Diligence
Employee interviews. Meet key employees (with the seller’s permission). Understand the team’s capabilities and flight risk.
Customer conversations. Talk to major customers about their relationship, satisfaction, and likelihood of continuing after a transition.
Systems and technology. Evaluate the tech stack, software, equipment condition, and any upcoming capital expenditure needs.
Facility review. Visit the location(s). Evaluate the lease terms, condition of the space, and any deferred maintenance.

6. From LOI to Close: The Final Stretch
The Letter of Intent (LOI)
The LOI is where the deal gets real. It’s a non-binding agreement (with a few binding provisions, like exclusivity and confidentiality) that outlines the key terms: purchase price, deal structure, timeline, and conditions. Think of it as the blueprint for the deal. For a detailed breakdown of what goes into an LOI and how it differs from an IOI, see our guide on what an LOI is and what it covers.
Negotiating the Deal Structure
Asset sale vs. stock sale. Most small business deals are structured as asset sales, where you’re buying the assets of the business (equipment, inventory, customer lists, goodwill) rather than the legal entity. Asset sales are generally better for buyers from a tax perspective. Stock sales are more common in larger deals or when the business has non-transferable contracts or licenses. We cover the difference in detail in asset sale vs. stock sale.
Earnouts. An earnout ties a portion of the purchase price to the future performance of the business. They’re a tool for bridging a valuation gap — the seller thinks the business is worth $3M, you think $2.5M, so you structure $2.5M at close plus $500K contingent on hitting revenue targets. Earnouts can work, but they need to be structured carefully. See our guide on when earnouts work and when they don’t.
Reps and warranties. These are the promises the seller makes about the business — that the financials are accurate, that there are no pending lawsuits, that all contracts are valid. They’re your protection if something turns out to be untrue after closing. Your attorney will negotiate these carefully. For more, see reps and warranties in M&A.
