How to Buy a Business in the U.S.: Complete 10-Step Guide for First-Time Buyers

Buying an existing company can give you revenue, customers, employees, and operating history from day one. Learning how to buy a business means knowing what to verify before your money and liability move. In the U.S., a careful purchase combines valuation, financing, legal diligence, tax planning, and a written transition plan. Elsewhere on the site: Business Site Meaning.

Quick facts for U.S. business buyers

Direct answer: To buy an existing U.S. business, first define your budget and target. Then find candidates, verify earnings, value the company, arrange financing, negotiate an LOI, and complete financial and legal due diligence. Choose the deal structure with advisers, sign the purchase agreement, close, and manage a planned ownership transition.

Key takeaways

• Decide what you can afford before reviewing listings.
• Judge price against verified earnings, not seller projections.
• Keep working capital and transaction expenses outside your purchase-price budget.
• Use due diligence to confirm revenue, liabilities, contracts, licenses, and owner dependence.
• Discuss the acquisition structure with a CPA and attorney before signing final documents.
• Plan the seller handover before closing, not after ownership changes.

What you’ll need before you start

A serious buyer needs more than enough cash for a down payment. You also need room for professional fees, working capital, lender costs, and post-closing surprises. A lender prequalification can help you avoid pursuing deals that your financing cannot support.

Your advisory team may include the following professionals.

• A CPA with business acquisition experience.
• A transaction or M&A attorney.
• An SBA or commercial lender.
• A business broker or intermediary.
• An industry specialist when technical risks require one.

The SBA recommends examining investment size, skills, infrastructure, contracts, cash flow, licenses, and valuation before purchasing an existing company. Professional legal and accounting help also becomes useful as the deal becomes more detailed.

How to Buy a Business in 10 Steps

1. Define the business you want to own. Set your preferred industry, location, revenue range, cash flow, purchase price, and daily involvement. Avoid chasing attractive listings that do not fit your skills or available capital.
2. Find businesses that match your criteria. Search business marketplaces, local brokers, industry associations, professional networks, and direct-owner opportunities. Business Strategy’s small-business coverage can also help you research common operating issues before choosing an industry.
3. Screen the company before spending heavily on diligence. Ask why the owner is selling and how involved that owner remains. Review customer concentration, employee dependence, recurring revenue, major equipment, leases, and recent financial trends.
4. Verify earnings and estimate a reasonable value. Request tax returns, profit-and-loss statements, balance sheets, bank records, and supporting documents. Compare normalized earnings with suitable market, income, and asset valuation methods instead of relying on the asking price. The SBA identifies several valuation approaches and recommends an objective investigation before purchase.
5. Build a financing plan before making a firm commitment. Buyers may combine cash, commercial financing, seller financing, and SBA-backed funding. The SBA 7(a) loan program permits complete or partial ownership changes, with eligible loans reaching $5 million.
   Under current SOP 50 10 8, a complete ownership change generally requires at least 10% equity of total project costs. A lender may still require more capital based on the borrower and transaction. SBA 50 10 8.1 becomes effective October 1, 2026, so confirm current requirements with your lender before structuring financing.
6. Negotiate the main terms in a letter of intent. An LOI commonly addresses price, financing, transaction structure, included assets, diligence time, confidentiality, and closing conditions. Have your attorney review binding provisions before you sign them.
7. Run financial, legal, and operational due diligence. Reconcile reported revenue against tax returns, bank deposits, payroll, and sales records. Review contracts, debt, liens, lawsuits, insurance, permits, equipment, employees, suppliers, and customer concentration.
   A leased location deserves separate attention because the landlord may need to approve an assignment.
8. Choose between an asset purchase and an equity purchase. This decision affects liabilities, contracts, taxes, permits, and how ownership transfers. Choose with your attorney and CPA because the consequences vary by entity and state.

U.S. tax rules treat a lump-sum sale of business assets as a transfer of each asset for tax purposes. Buyer and seller generally use the residual method when the applicable rules apply. Both parties may also need to report the allocation on IRS Form 8594.

9. Turn diligence findings into the purchase agreement. The final contract should identify the purchase price, payment terms, assets, liabilities, and closing conditions. It may also address representations, warranties, indemnification, working capital, employee matters, and seller transition duties.
10. Close the transaction and protect the handover. Confirm financing, signatures, licenses, lease matters, insurance, accounts, and approved funds before ownership transfers. Then follow a written transition schedule covering employees, customers, suppliers, passwords, systems, and seller training.

A stable handover can protect the value you paid for. Avoid changing every process during your first week unless a serious problem demands action. Business Strategy’s guide to software and services businesses use for daily operations can help when reviewing inherited systems after closing.

A simple walk-away test before closing

A purchase can look attractive while one unresolved problem changes its economics. Write your deal breakers before you become emotionally committed to the transaction. Then apply those rules consistently after diligence produces new information.

Consider stopping or renegotiating when:

• Revenue cannot be reconciled with reliable records.
• Major customers may leave after ownership changes.
• Important permits or contracts cannot transfer.
• The seller cannot support claimed financial add-backs.
• Undisclosed debts, liens, disputes, or tax issues appear.
• The company depends heavily on knowledge the seller cannot transfer.
• Required working capital makes the transaction unaffordable.

Walking away from one unsuitable acquisition preserves your capital for another opportunity. A lower price does not automatically cure legal or operational problems. The underlying business must still work after the seller leaves.

How much money do you need to buy an existing business?

The required cash depends on the price, lender, transaction structure, and operating needs. Budget for equity, legal and accounting fees, lender costs, working capital, and personal reserves. Under current SBA rules, complete ownership changes using 7(a) financing generally start with a 10% equity requirement on total project costs.

Do not assume a 10% equity figure means you only need 10% of the advertised purchase price. Total project costs can include expenses beyond the seller’s headline number. Ask a lender to model the full cash requirement before submitting an offer.

How long does buying a business take?

The timeline varies with your search, financing, licensing, diligence, and transaction complexity. Current buyer guides commonly describe a process lasting several months, with many estimating roughly six to twelve months. Due diligence and financing can consume several weeks after an LOI is signed.

You can shorten delays by preparing financial documents and contacting lenders early. Clear acquisition criteria also reduce time spent evaluating unsuitable listings. Rushing diligence to meet an artificial deadline can create much larger problems later.

Frequently Asked Questions

What documents should I review before buying a company?

Start with several years of tax returns, financial statements, bank records, payroll, and accounts receivable information. Review customer contracts, vendor agreements, leases, insurance, licenses, debts, liens, employee obligations, and litigation. Your attorney and CPA can adjust the request list for the industry and transaction.

How do you buy a business with an SBA loan?

Start by speaking with an SBA-participating lender before committing to a purchase. The 7(a) program can finance eligible ownership changes, and its current maximum loan amount is $5 million. Eligibility, equity, collateral, repayment ability, and transaction rules still apply to each deal.

Is buying an existing company safer than starting from scratch?

An acquisition gives you operating history that a new venture cannot provide. You can examine existing revenue, customers, expenses, staff, and systems before purchasing. Those advantages do not remove the risk of hidden liabilities, customer losses, or paying too much.

Should I buy the assets or the company itself?

There is no single structure that fits every buyer. Asset and equity purchases create different legal, contractual, and tax effects. Have a transaction attorney and CPA review both structures before final terms become difficult to change.

Your next step

Start by writing a one-page acquisition profile with your industry, location, budget, income target, and operating role. Then speak with a lender before investing heavily in listings or negotiations. A clear buy box and funding range make every later decision easier.

Treat every seller claim as information that still needs verification. Use professional advice for tax, financing, and legal questions that depend on your transaction. The goal is not merely to close a deal but to understand what you will own on the morning after closing.
