How to Buy a Small Business: Step by Step

How to buy a small business: the process at a glance

Most small business acquisitions follow the same broad sequence, even though every deal is different:

1. Decide whether buying is right for you, and what you are looking for.
2. Set a budget based on your cash and realistic financing.
3. Source deals.
4. Screen and value opportunities.
5. Make an offer with a letter of intent (LOI).
6. Arrange financing.
7. Run due diligence.
8. Negotiate the purchase agreement and close.
9. Manage the transition and the first 100 days.

The whole process often takes many months from starting the search to closing. Plan for it to take longer than you expect, and expect most deals you look at to fall away.

Step 1: Decide what you're really buying

Before you look at listings, write down your acquisition criteria. A clear thesis saves months of wasted analysis.

• Your role: do you want to run the business day to day, or own it with a manager in place? Owner-operator businesses are cheaper relative to earnings but you are buying a job as well as an asset.
• Industry and skills: where do your experience, network and interests give you an edge?
• Size: a range of earnings or price that fits your budget.
• Business model: recurring revenue, low customer concentration, reasonable capital needs.
• Location: local, regional or remote-run (for many online businesses).
• Deal-breakers: licences you cannot obtain, heavy regulatory risk, or industries you do not want to be in.

Step 2: Set your budget

Your budget depends on the cash you can commit, the lender's equity requirements, whether the seller will finance part of the price, and a cash buffer for closing costs and working capital.

Keep a reserve outside the deal. Many first-time buyers underestimate the cash needed after closing for working capital, unexpected repairs and transition costs.

Step 3: Find businesses for sale

Deals come from several channels, and the best opportunities are often not widely advertised:

• Online listing marketplaces for main street and online businesses.
• Business brokers and M&A advisors who represent sellers. Build relationships so you hear about deals early; see business brokers explained.
• Direct outreach to owners who are not actively selling, especially owners nearing retirement.
• Professional networks: accountants, attorneys, bankers and industry associations often know owners who are planning to exit.
• Your industry: suppliers, customers and competitors.

Direct outreach takes longer but can surface businesses with less competition from other buyers.

Step 4: Screen and value opportunities

You will look at far more businesses than you pursue. Screen quickly and consistently:

• Is the business consistently profitable on a normalized basis?
• How concentrated are customers and suppliers?
• How dependent is the business on the current owner?
• Is revenue recurring, repeat or one-off?
• Is the industry stable or declining?
• Why is the owner selling?

Score each target with the Acquisition Quality Score, then build a value range using our business valuation guide and calculator.

Ask for the confidential information memorandum (CIM) or listing package, and expect to sign a non-disclosure agreement (NDA) before receiving detailed financials.

Step 5: Make an offer with a letter of intent

When a business passes your screen and initial conversations, you make a written, mostly non-binding offer in a letter of intent (LOI). It covers the price, structure (asset vs stock purchase), financing, seller note, working capital, transition support, exclusivity and key conditions. Our letter of intent guide and template walks through each clause.

Tip: a well-structured LOI that shows you can actually close is often more persuasive to a seller than a slightly higher but vaguer offer.

Step 6: Arrange financing

Most buyers combine their own equity with lender debt and seller financing. Start lender conversations early so you know what is achievable, then run the numbers on the actual deal:

Read business acquisition financing and seller financing for details on SBA loans, conventional debt, seller notes and earnouts.

Step 7: Run due diligence

Due diligence is where you verify that the business is what the seller says it is. It covers financial, tax, legal, operational, commercial, HR and technology matters. It is usually done with an accountant (often a quality of earnings review for larger deals) and an attorney. Use our business due diligence checklist.

Typical diligence findings lead to one of three outcomes: proceed as agreed, renegotiate price or terms, or walk away. Walking away from a bad deal is a success, not a failure.

Step 8: Purchase agreement and closing

The definitive agreement (an asset purchase agreement or stock purchase agreement) turns the LOI into binding terms. Key areas include representations and warranties, indemnification, escrows or holdbacks, non-compete and non-solicit provisions (subject to local law), working capital adjustments, and transition services.

Asset purchases and stock purchases have different legal and tax consequences for buyers and sellers. Get advice from an attorney and tax adviser.

At closing, funds are transferred, ownership passes, and loan documents, seller notes and any lease assignments are signed.

Step 9: The transition and first 100 days

The transition is where many acquisitions succeed or fail.

• Agree a transition plan with the seller in the purchase agreement: how long they stay and what they do.
• Communicate carefully with employees, customers and suppliers. Uncertainty creates turnover.
• Change little at first. Learn how the business really works before making big changes.
• Track cash weekly. Debt payments start immediately.
• Document processes that lived in the seller's head.

Common mistakes first-time buyers make

• Searching without clear criteria.
• Falling in love with a deal and skipping diligence.
• Over-leveraging and leaving no buffer for a bad quarter.
• Underestimating owner dependence.
• Ignoring working capital needs.
• Not budgeting for professional fees.
• Changing too much too fast after closing.

The right structure depends on taxes, contracts, licences and liability considerations. Get advice from an attorney and tax adviser before you commit in an LOI.

• Value: Business Valuation Calculator
• Finance: Acquisition Financing Calculator and Seller Financing Calculator
• Operate: Break-Even Calculator

Revisit them as new information comes in. The numbers you use at the screening stage will change once you see verified financials.

A realistic timeline

Buying a business takes longer than most first-time buyers expect. The stages below are a typical sequence, but the time each one takes varies widely with the deal, the seller and the financing.

Plan your personal finances around the slow case, not the fast one, especially if you are leaving a job to search full time.

Your buy box: write it before you search

A buy box is a short written description of the business you are looking for. It saves time because it lets you reject most listings in minutes and explain to brokers exactly what you want. A useful buy box includes:

• Size: a range of annual earnings (SDE or EBITDA) that fits your budget and financing.
• Industry and model: sectors you understand or can learn, and preferred revenue models such as recurring service contracts.
• Location: where you can realistically operate, or whether you need a remote-friendly business.
• Owner role: what you are willing to do day to day.
• Deal breakers: heavy customer concentration, regulatory exposure, declining revenue or anything else you will not accept.

Revisit the buy box after your first few serious conversations. Real deals teach you what you actually value.

Working with advisors

Most buyers need an accountant, a lawyer experienced in business acquisitions and a lender. Some also use a broker on the buy side or an industry advisor. Hire advisors who do acquisitions regularly; general practitioners may miss deal-specific issues such as working capital targets, indemnity caps or lease assignment. Ask for fee estimates in writing and agree what is in and out of scope.

Decision checkpoints

Build three explicit checkpoints into your process, and be willing to stop at each one:

1. Before the LOI: do the numbers work at the price you are offering, using the deal analyzer?
2. Before spending on third-party diligence: has anything in the first document review contradicted what you were told?
3. Before signing the purchase agreement: if you knew everything you now know at the start, would you still have made this offer?

Where to go next
