How to Buy a Business: The Step by Step Process

Most guides on how to buy a business hand you a list of stages: find a target, value it, run diligence, close. That list is not wrong, and it is also not the part anyone gets wrong. What buyers get wrong is timing. They retain an attorney after the letter of intent is already drafted. They meet a CPA at closing, when the entity structure is long since fixed. They find out whether a deal is bankable after they have already committed to a price in writing. This guide sequences the process by when each professional enters, because that ordering decides how well everything downstream goes.

The sequence below is a generic template, not a diary of any particular transaction. Elapsed times are given as ranges because the second half of an acquisition runs on someone else's clock.

When each advisor enters, and what waiting costs you

Every professional in an acquisition has a moment when their input is cheap and decisive, and a later moment when the same input is expensive and mostly cosmetic.

The step by step process

Is buying an existing business actually a good idea?

For most people with capital and operating experience, yes, and the reason is narrow: you are buying proven cash flow instead of a hypothesis. An existing business has customers who have already decided to pay, employees who already know the work, and a filed earnings history a lender can underwrite. That last point is not a small advantage. Financing an acquisition is materially easier than financing a startup precisely because historical cash flow satisfies debt service coverage tests that projections cannot, a gap worth understanding in detail if you are still weighing a startup against an acquisition.

The drawbacks are real and they cluster in three places. You inherit everything, including the liabilities you did not find, the customer who is about to leave, and the employee who has been quietly running the place. You pay for goodwill, meaning you pay today for earnings the seller already produced, and you carry debt against them from day one. And you are buying at an information disadvantage that never fully closes, because the seller has run this business for years and you have read about it for weeks.

Readiness is mostly about three things: enough liquid cash for a down payment plus real working capital reserve, enough credit and personal balance sheet to survive an unlimited personal guarantee, and enough relevant operating experience that a lender believes you can run the thing. If any of those three is missing, the honest answer is that you are not ready yet, and no structure fixes it.

Building the model before the first price conversation

The model is the piece of work that separates buyers who negotiate from buyers who react. Build it before you have a specific target, using industry-typical inputs, so that when a real set of financials arrives you are populating a machine rather than starting one.

The levers that need to move independently: purchase price, equity injection, seller note amount and terms, interest rate, amortization period, normalized earnings after add-backs, and your own salary. The outputs that matter: debt service coverage ratio, cash left over after debt service and your compensation, and the price at which coverage falls below what a lender will accept.

Debt service coverage is the number that decides most deals. It is annual cash flow available for debt service divided by annual principal and interest. A DSCR calculator will give you the ratio, and the deal analyzer will model the full structure including the seller note and the injection. What you are looking for is not a single answer but a sensitivity: how much can the price rise, or earnings fall, before this stops working.

Then write your walk-away logic down, dated, before you have met a seller you like. Price ceiling. Minimum coverage. Maximum customer concentration. Minimum remaining lease term. Buyers who set these afterward invariably set them exactly where the current deal happens to sit.

Finding businesses that are genuinely for sale

Three channels, with different economics.

Listing marketplaces are the most visible. BizBuySell is the largest, and brokers list there because that is where buyers look. The trade-off is competition and presentation: a listed business has been packaged, priced with an asking multiple in mind, and shown to everyone. The financial summary in a listing is marketing.

Brokers are worth cultivating directly, especially ones who specialize in your industry or geography. A broker who knows you are real, funded, and quick will show you things before they are listed. Understand the incentive structure while you do it, because the broker is paid on close, by the seller. That makes every interaction simultaneously useful and adversarial. When a broker suggests improvements to your offer before presenting it, that advice is genuinely valuable, because they know what the seller will accept. It is also the seller's counter delivered without the seller's fingerprints on it. Both things are true at once.

Direct outreach to unlisted owners is the slowest channel and the one with the least competition. It also produces the messiest financials, because an owner who never planned to sell never prepared to be diligenced.

Whatever the channel, ask early why the business is for sale, and then test the answer against what you see. Retirement is the most common reason and the most commonly stated one, which is exactly why it needs checking. Look at the trend in the financials, the age of the equipment, the remaining lease term, and whether any large customer contract is up for renewal shortly after closing. A seller exiting ahead of a known cliff will tell you they are retiring, and they may also genuinely be retiring.

Reading the financials

The hierarchy is not a matter of taste. Audited statements sit above reviewed statements, which sit above compiled statements, which sit above tax returns, in terms of the assurance a professional attached to them. But for a small business that has none of the first three, the filed tax return is the document with real consequences behind it, and a management-prepared P&L is a document with none.

So reconcile in that direction. Take the seller's P&L and tie each major line to the return. Where they disagree, the disagreement is the finding. Common and legitimate causes include book-to-tax timing differences and cash versus accrual method. Common and less legitimate causes include add-backs that were never disclosed as add-backs and revenue recognized early.

Interim statements deserve their own paragraph of suspicion. They routinely omit depreciation because nobody books it monthly, which silently inflates earnings for the trailing period a seller most wants to present well. If a trailing twelve month figure is doing heavy lifting in the asking price, ask specifically how depreciation was handled in it.

For the full item-by-item sequence, work from a due diligence checklist ordered by deal stage rather than by category, because the order in which you find problems determines how much you have spent by the time you find them.

Valuing the business

Three approaches, and only one of them usually decides the price.

The earnings multiple approach dominates small business sales. Normalize earnings to seller's discretionary earnings or EBITDA, apply a multiple drawn from comparable transactions in the industry, and you have a number. The whole argument lives in the normalization: which add-backs survive scrutiny, and whether the earnings are durable. Asset-based valuation matters when the tangible assets are worth more than the earnings stream, which is a warning sign in an operating business and the whole point in an equipment-heavy one. Cash flow analysis, in the sense of discounting projected future cash flows, is rarely what a small business transaction actually turns on, though it is what your lender is implicitly doing when they test coverage.

Two practical points that competing guides tend to skip.

First, the number you compute is an offer-stage sanity check, not the number that governs. In an SBA-financed acquisition the valuation that matters must be commissioned by and prepared for the lender, produced by an accredited qualified source, and a valuation prepared for you or for the seller cannot be used. If the price exceeds the valuation, the difference has to be covered with equity, not debt. Work through how to value a small business before you make an offer, and treat any online calculator, including ours, as a screening instrument.

Second, your add-backs get re-tested later. Anything you normalized out of the earnings will be examined again in the quality of earnings report if the deal needs one, and the lender must use the QoE's earnings figure in the coverage calculation. An aggressive add-back that gets you to an attractive multiple in week four becomes a loan reduction in week sixteen.

Financing the purchase

By the time you are having a serious price conversation you need to know how the purchase is funded, because the funding source constrains the structure.

The routes available to an acquisition buyer are a government-guaranteed loan, a conventional bank loan, seller financing, some form of bridge or asset-based lending, and equity from a partner. In practice most small business acquisitions in the United States run through the SBA 7(a) program, because conventional lenders are generally unwilling to lend against goodwill and a 7(a) loan will.

The consequences of that choice are worth knowing before you commit to a price, because SBA rules govern structure rather than merely pricing it:

• The equity injection for a first acquisition is a minimum of ten percent of total project cost and cannot be reduced or eliminated.
• Seller financing can supply at most half of that injection, and only on full standby, meaning no payments of principal or interest for the entire term of the loan.
• Loans facilitating a change of ownership must not have an amortization longer than ten years, per 13 CFR 120.212 and the SBA's operating procedures. That single constraint drives the monthly payment, and therefore the maximum supportable price, more than the interest rate does.
• Anyone owning twenty percent or more of the buyer gives an unlimited full guaranty.

This is also the reason the no money down versions of this question mostly resolve to no. A first acquisition's injection is not reducible, and the seller note covers half of it at most.

Rules in this area move. The SBA's current operating procedure, SOP 50 10 8.1, was published on August 14, 2026 and takes effect October 1, 2026, and it changes several things that matter to buyers, including a mandatory quality of earnings report at a three million dollar purchase price and a higher coverage floor for acquisitions. The details are collected in our breakdown of the SOP 50 10 8.1 changes. Check the current version at SBA.gov rather than relying on any secondary summary, including this one, once time has passed.

The letter of intent

The LOI is the most consequential document most buyers treat casually. It is mostly non-binding: typically only the confidentiality and exclusivity provisions actually bind. That is exactly why its assumptions matter. They are not promises, they are tripwires, and each one you write down is a condition you can later point to when diligence contradicts it.

Things worth making specific: minimum earnings measured on the seller's own workpaper methodology so no definitional argument is possible later, debt-free and lien-free delivery, adequate working capital at closing, lease terms including square footage and rate, non-compete scope and duration, and the expiration date. Things worth leaving deliberately vague: the working capital peg pending a quality of earnings report, and retained inventory. Our full treatment of what to make specific and what to leave vague in an LOI goes clause by clause.

Timing language should read as targeting a number of days subject to lender underwriting, because you do not control underwriting and should not promise as though you do.

Confirmatory diligence, the QoE, and underwriting

Once the LOI is signed, exclusivity starts running and so does real spending. This is the phase where you order the reports, your attorney drafts or reviews the purchase agreement, and the lender begins underwriting.

The quality of earnings report deserves specific attention because buyers misunderstand who it is for. It is financial due diligence performed for the lender's benefit, and it may not be prepared by or for the borrower or the seller. It reconciles accountant-prepared statements, tax returns, internal statements, and IRS transcript data into a normalized earnings figure, and it includes a cash proof that reconstructs cash receipts and disbursements from bank statements against the income statement and tax return. Under the current rules a QoE is mandatory when the business purchase price is three million dollars or more, measured before any buyer equity or seller debt is applied. Pick the firm with your banker.

The consequence buyers do not expect: if the coverage calculated from the QoE's earnings does not support the valuation and the proposed debt structure, the loan amount has to come down. Additional equity can bridge that, or the price does. This is the single most common late-stage renegotiation trigger in an SBA-financed acquisition.

Underwriting itself is largely outside your control. Your job in it is responsiveness. Every document request answered the same day is a day you did not add to the timeline, and the difference between an organized borrower and a disorganized one is measured in months. If you are still selecting a lender, acquisition experience matters more than rate, and you can compare lenders by actual acquisition funding volume rather than by marketing.

Closing and the first ninety days

Closing is mechanical if diligence was thorough: conditions precedent satisfied, the purchase agreement signed, funds wired, keys and passwords transferred. The purchase price allocation across asset classes gets reported to the IRS on Form 8594 by both parties, and it affects both sides' taxes, which is one more reason the CPA needed to be in the room months earlier.

The transition is where value actually gets preserved or lost. Have customer and vendor introductions scheduled before closing rather than after. Know which employees are critical and what you are offering them to stay, and remember that the site visit was supposed to have told you who else was leaving besides the owner. Watch working capital in the first sixty days, because acquisition buyers routinely close with enough cash for the purchase and not enough for the two months afterward, and if your lender eliminated the equity requirement there are rules restricting permanent working capital in a term loan for a period after closing.

If a transitional consulting arrangement with the seller is part of the plan, note that under SBA rules the seller may not remain an officer, director, stockholder, or employee of the business, and a consulting contract is capped at twenty four months in aggregate including extensions.

How long the whole thing takes

Two halves, with very different characteristics.

The first half is yours. An organized buyer who has the model built, the walk-away rules written, and the advisors lined up can go from first broker contact to a signed letter of intent in a matter of weeks. The variables are how fast the seller produces documents and how much reconciliation the financials need. Buyers who have not built the model in advance routinely spend twice as long here, because every new number restarts the analysis.

The second half is not yours. From signed LOI through confirmatory diligence, the quality of earnings, the lender's valuation, underwriting, and closing typically runs considerably longer than the first half, and most of the elapsed time is spent waiting on third parties: the appraiser's queue, the QoE firm's fieldwork, the credit committee's calendar, the landlord's consent to a lease assignment. Weeks will pass where nothing visible happens.

That is why a single total is not a useful number and this guide does not give one. What is useful is knowing which delays you can prevent, which is nearly all of the ones in the first half and almost none of the ones in the second.

The short version

The stages are not the hard part; every guide lists them. The advantage is the sequence of people: bring each advisor in while their input is still cheap and decisive, before the letter of intent rather than after.
