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

Learning how to buy a business is one of the fastest paths to financial independence. Whether you want to know how to purchase business assets, understand the process of buying and selling a business, or simply need a clear roadmap, you are in the right place. Instead of spending years building something from zero, you acquire an existing operation with customers, revenue, and cash flow on day one. But the process has many steps, and getting any of them wrong can cost you hundreds of thousands of dollars.

This guide walks you through every stage of buying a business - from deciding what to buy through closing and your first 90 days as the new owner. These steps to buying a business work whether you are a first-time buyer or an experienced operator adding to your portfolio.

Step 1: Decide What You Want to Buy

Before you look at a single listing, get clear on what you want. Skipping this step leads to months of wasted time chasing deals that are wrong for you.

Define your criteria

Start with these questions:

• Industry. What industries match your skills and interests? You do not need direct experience, but you need transferable skills. A sales background works well for service businesses. A finance background helps with anything numbers-heavy. See our guide to the best businesses to buy for a breakdown of 10 strong acquisition categories.
• Size. What SDE range fits your budget and goals? First-time buyers typically target $150K - $500K in SDE. That translates to purchase prices of roughly $400K - $2M depending on the industry multiple.
• Location. Do you want a local business you can visit daily, or are you open to remote operations? Ecommerce and SaaS are location-independent. Service businesses and restaurants require local presence.
• Your role. Do you want to be the operator running the business daily, or do you want a semi-passive investment with a manager in place?
• Budget. How much cash can you contribute? Most deals require 10-20% down. Add $10K - $25K for legal, accounting, and due diligence costs.

Write these criteria down. When you start seeing deals, it is easy to get excited and chase opportunities outside your strike zone. Your criteria keep you disciplined.

Understand your financing options early

Talk to lenders before you start searching. Getting pre-qualified for an SBA loan tells you exactly what you can afford. It also makes you a more credible buyer when you approach sellers and brokers. Sellers take you seriously when you can show proof of financing.

Step 2: Search for Businesses

Finding the right business takes time. Most buyers look at 50-100 opportunities before making an offer on one. Here is where to look:

Online marketplaces

BizBuySell is the largest marketplace for businesses for sale. Other options include BizQuest, BusinessBroker.net, and Acquire.com (for online businesses). These platforms list thousands of businesses with basic financial details and asking prices.

Business brokers

Brokers represent sellers and earn a commission (typically 8-12% of the sale price). Good brokers screen businesses before listing them, which saves you time. Build relationships with 3-5 brokers in your target industry and geography. Let them know your criteria so they send you relevant deals.

Direct outreach

The best deals are often off-market. Send letters or emails directly to business owners in your target industry. Many owners have thought about selling but have not listed their business. A well-crafted outreach letter can start a conversation that leads to a deal with no broker commission and less competition.

Your network

Tell everyone you know that you are looking to buy a business. Accountants, lawyers, bankers, and industry contacts often know of businesses that are or will be for sale. Word-of-mouth deals tend to have better terms because trust is already established.

Whether you are considering a franchise or an independent business, casting a wide net at this stage gives you the best chance of finding the right deal.

Step 3: Initial Screening

Most businesses you look at will not be worth pursuing. Your goal at this stage is to quickly filter out bad deals so you can focus your time on good ones.

Quick financial review

Ask for a summary of revenue, expenses, and SDE for the last three years. If the numbers are trending down, ask why. If the seller cannot provide basic financials, move on. You need to understand SDE and how to calculate it before you can evaluate any deal.

Key screening questions

Ask these questions early in the process:

• Why is the owner selling?
• How involved is the owner in daily operations?
• What percentage of revenue comes from the top 3 customers?
• Are there any pending lawsuits, liens, or regulatory issues?
• What does the lease situation look like?
• How long has the business been for sale?

The answers tell you whether to dig deeper or walk away. A business with a declining revenue trend, a departing key employee, and a lease expiring in 6 months is not worth your time regardless of the asking price.

Watch for red flags in business acquisitions at this stage. Catching them early saves you thousands in legal and due diligence costs.

Step 4: Letter of Intent (LOI)

When you find a business worth pursuing, the next step is submitting a Letter of Intent. The LOI is a non-binding document that outlines the proposed deal terms. It gets both parties aligned before you spend money on due diligence.

Read our full guide on letters of intent for business purchases for templates and details. Here is what to include:

Key LOI terms

• Purchase price. Your proposed price based on your initial financial review. This may change after due diligence.
• Deal structure. Asset purchase vs. stock purchase. Most small business acquisitions are asset purchases because they limit your liability exposure.
• Financing. How you plan to pay - SBA loan, seller financing, cash, or a combination.
• Due diligence period. Typically 45-90 days. This is your window to verify everything.
• Exclusivity. You want the seller to stop marketing the business while you conduct due diligence. This is standard and reasonable.
• Seller transition. How long the seller will stay to help with the transition. Typically 30-90 days post-closing.
• Contingencies. Conditions that must be met for the deal to close - financing approval, lease assignment, key employee retention.

The LOI is your chance to anchor the negotiation. Start with a fair but favorable price. The seller will counter. You negotiate from there.

Step 5: Due Diligence

Due diligence is the most critical phase of how to buy a business. This is where you verify every claim the seller has made and uncover risks that were not disclosed. Cutting corners here is the number one reason acquisitions fail.

Use our due diligence checklist tool and our comprehensive due diligence checklist guide to make sure you do not miss anything.

Financial due diligence

• Review 3 years of tax returns and compare them to the P&L statements
• Verify revenue by matching invoices to bank deposits
• Analyze expense categories for anything unusual or non-recurring
• Calculate normalized SDE using the SDE vs EBITDA framework that fits the business
• Review accounts receivable aging - old receivables may be uncollectible
• Check for any off-balance-sheet liabilities
• Verify inventory counts and condition if applicable

Legal due diligence

• Review all contracts: customer agreements, vendor agreements, leases, employment contracts
• Check for pending or threatened litigation
• Verify all licenses and permits are current and transferable
• Review intellectual property ownership
• Check for any environmental issues (especially for businesses with physical locations)
• Confirm the business has proper insurance coverage

Operational due diligence

• Assess owner dependency - what happens when the seller leaves?
• Evaluate key employees and their likelihood of staying post-acquisition
• Review standard operating procedures and systems
• Analyze customer concentration - is revenue diversified?
• Visit the business during operating hours, unannounced if possible
• Talk to customers, suppliers, and employees (with seller permission)

Market due diligence

• Assess the competitive landscape
• Research industry trends - is the market growing or shrinking?
• Evaluate the business's market position and reputation
• Review online reviews and social media presence

Due diligence typically costs $5,000 - $15,000 in professional fees (accountant, attorney, possibly an industry consultant). It is the best money you will spend in the entire process. Skipping it to save a few thousand dollars is how buyers end up with businesses that have hidden tax liabilities, expiring leases, or departing key customers.

Step 6: Valuation

Valuation is both art and science. The goal is to determine a fair price - what the business is worth to you as the buyer, not just what the seller wants.

The SDE method

For most small businesses (under $5M in revenue), SDE is the standard valuation metric. Calculate SDE by starting with net income and adding back:

• Owner's salary and benefits
• One-time or non-recurring expenses
• Personal expenses run through the business
• Depreciation and amortization
• Interest expense

Then apply the appropriate industry valuation multiple. A business with $200K in SDE in an industry that trades at 3.0x is worth approximately $600K.

Factors that affect the multiple

Not every business deserves the average multiple. These factors push the multiple up or down:

• Revenue trends. Growing businesses command higher multiples. Declining businesses get discounted.
• Owner involvement. Less owner dependency means a higher multiple.
• Customer concentration. Diversified revenue justifies a premium.
• Recurring revenue. Contracts and subscriptions increase predictability and value.
• Age and condition of assets. New equipment and good facilities add value.
• Growth potential. Clear, unfunded growth levers justify paying more.

Use our valuation calculator to run scenarios with different SDE figures and multiples. This helps you determine your maximum price before entering negotiations.

Step 7: Financing the Acquisition

Most buyers do not pay all cash. Here are the primary financing methods and how they work together:

SBA loans

The SBA 7(a) loan program is the most common financing method for small business acquisitions. Key features:

• Up to 90% financing (you put 10% down)
• 10-year terms for business acquisitions
• Interest rates typically Prime + 2-3%
• Requires personal guarantee and sometimes collateral
• Processing takes 45-90 days

Our full guide on SBA loans for buying a business covers qualifications, the application process, and how to improve your chances of approval.

Seller financing

Seller financing means the seller acts as your lender for a portion of the purchase price. This is common and often expected. Typical terms: 10-30% of the purchase price, 5-7 year term, 5-8% interest rate. Seller financing is powerful because it keeps the seller invested in your success during the transition.

Cash

If you have the capital, paying cash gives you maximum leverage in negotiations. Sellers prefer cash deals because they close faster and carry less risk. Cash buyers can often negotiate 10-20% discounts on the purchase price.

ROBS (Rollover for Business Startups)

ROBS allows you to use retirement funds (401k, IRA) to buy a business without paying early withdrawal penalties or taxes. It is complex and requires a specialized provider to set up. Not every situation qualifies. But for buyers with significant retirement savings and limited cash, it can be a viable option.

Combining financing sources

The strongest deal structures combine multiple sources. A typical structure: 10% buyer cash down payment, 70-80% SBA loan, 10-20% seller note. This reduces your cash outlay while giving the seller most of their money at closing.

Step 8: Negotiation

Negotiation is where your due diligence work pays off. Every risk, every discrepancy, every issue you uncovered is a tool for adjusting the deal in your favor.

Using DD findings

Present your findings factually. "The financials show SDE of $180K, not the $220K represented. Based on that, the valuation at 3x is $540K, not $660K." Sellers respect data-driven negotiation. They do not respect lowball offers with no justification.

Read our detailed guide on how to negotiate the purchase price for specific tactics and frameworks.

Deal structure levers

Price is only one variable. These structural elements can make a deal work even when the price gap seems too wide:

• Earnouts. A portion of the price is paid based on future performance. This bridges valuation gaps and protects you if the business underperforms.
• Seller notes. A seller note with a standby provision (no payments for 6-12 months) gives you cash flow breathing room early on.
• Holdbacks. Withholding 5-10% of the purchase price in escrow for 6-12 months protects you against undisclosed liabilities that surface post-closing.
• Working capital adjustments. Define a target working capital level. If the actual working capital at closing is below target, the price adjusts down.
• Non-compete agreements. Ensure the seller cannot open a competing business or solicit customers. Standard terms are 3-5 years within a defined geography.

The walkaway price

Before you start negotiating, determine your maximum price - the number where the deal no longer makes financial sense. Factor in your cost of capital, required return, and risk tolerance. Never exceed your walkaway price. There will always be another deal.

Step 9: Purchase Agreement and Legal

Once you agree on terms, your attorney drafts the purchase agreement. This is the binding legal document that governs the transaction. Do not use templates from the internet. Hire a business acquisition attorney.

Asset purchase vs. stock purchase

Most small business acquisitions are structured as asset purchases. You buy the assets of the business (equipment, inventory, customer lists, intellectual property, goodwill) rather than the legal entity. This protects you from unknown liabilities that existed before your ownership.

Stock purchases transfer the entire legal entity to you, including all liabilities. These are less common for small businesses but sometimes necessary when the business holds non-transferable contracts or licenses.

Key purchase agreement provisions

• Representations and warranties. The seller's written statements about the business - financial accuracy, legal compliance, disclosed liabilities. These are your legal protection if the seller misrepresented something.
• Indemnification. The seller agrees to compensate you for losses caused by breaches of reps and warranties. Negotiate a meaningful indemnification cap (typically 10-25% of purchase price) and survival period (12-24 months).
• Closing conditions. What must happen before closing - financing approval, lease assignment, key employee agreements, regulatory approvals.
• Purchase price allocation. How the price is divided among asset categories (equipment, goodwill, inventory, non-compete). This has significant tax implications for both buyer and seller.

Other legal documents

• Bill of sale
• Assignment and assumption of contracts
• Non-compete and non-solicitation agreements
• Seller transition services agreement
• Escrow agreement (if applicable)
• Promissory note (if seller financing)

Plan for $5,000 - $15,000 in legal fees for a straightforward deal. Complex transactions with multiple entities or real estate components cost more.

Step 10: Closing

Closing day is when ownership officially transfers. Here is what happens:

Pre-closing checklist

• Final walk-through of the business premises
• Verification that all closing conditions have been met
• Confirmation of financing and wire transfer instructions
• Review all closing documents with your attorney
• Ensure all required licenses and permits are transferred or applied for

At the closing table

• Both parties sign the purchase agreement and all ancillary documents
• Buyer wires the purchase price to escrow or directly to the seller
• Seller delivers keys, passwords, access credentials, and proprietary information
• Escrow agent disburses funds according to the closing statement
• Title to assets formally transfers to the buyer

Immediately after closing

• Change all bank accounts and signatory authority
• Update insurance policies
• File UCC statements if applicable
• Notify customers, vendors, and employees (per your communication plan)
• Update business registrations and licenses

Most closings take 2-4 hours. The preparation leading up to closing takes weeks. Your attorney and accountant should handle the details while you focus on your transition plan.

Step 11: Post-Closing Transition

Buying the business is only half the battle. The first 90 days of ownership determine whether the acquisition succeeds. This is where many buyers stumble.

First 30 days: listen and learn

• Do not change anything. Resist the urge to "improve" the business immediately. Your job in month one is to understand how it works.
• Meet every employee individually. Understand their role, concerns, and what they need from you. Employee retention is critical during ownership transitions.
• Meet key customers. Introduce yourself and reassure them that service quality will continue. If the previous owner had personal relationships with major clients, this is especially important.
• Shadow the seller. Spend as much time as possible with the outgoing owner. Learn the unwritten rules, the institutional knowledge, and the relationships that do not appear in any document.

Days 30-60: identify quick wins

• Review all expenses and eliminate obvious waste
• Identify the 2-3 highest-impact improvements you can make without disrupting operations
• Start documenting processes that exist only in the seller's head
• Begin building relationships with suppliers and negotiate better terms where possible

Days 60-90: implement and grow

• Roll out your first operational improvements
• Start executing on the growth plan you developed during due diligence
• Evaluate staffing needs - do you need to hire, restructure, or upgrade?
• Set up your financial reporting and KPI dashboards
• Reduce seller involvement as you become self-sufficient

Customer retention is everything

The biggest post-acquisition risk is losing customers during the transition. Proactive communication solves this. Contact your top 20% of customers (who likely represent 80% of revenue) personally within the first two weeks. Reinforce continuity. Ask what they need. Deliver on every promise the previous owner made.

How Long Does It Take to Buy a Business?

The full process from search to closing typically takes 6-12 months:

• Search: 1-6 months depending on your criteria and market
• Initial screening and LOI: 2-4 weeks
• Due diligence: 45-90 days
• Financing: 30-60 days (often runs parallel with due diligence)
• Negotiation and legal: 2-4 weeks
• Closing: 1-2 weeks

Rushing the process leads to mistakes. Taking too long loses deals. Aim for steady, consistent progress at each stage.

Common Mistakes When Buying a Business

After helping hundreds of buyers analyze acquisitions, these are the mistakes we see most often:

• Falling in love with the business. Emotional attachment clouds judgment. Stay objective and let the data guide your decisions.
• Skipping due diligence. "The seller seems honest" is not a substitute for verifying the financials. Trust but verify everything.
• Overpaying. Paying a premium for "potential" is risky. Value the business based on current performance, not what you hope to achieve.
• Underfunding working capital. Buyers focus on the purchase price and forget they need cash to operate the business. Budget for 3-6 months of working capital beyond the acquisition cost.
• Ignoring culture. If you plan to make radical changes immediately, you will lose employees and customers. Respect what made the business successful before you try to change it.
• Not getting professional help. An experienced acquisition attorney and a CPA who understands business acquisitions are worth every dollar. They catch issues you will miss.
