In short
Selling a small or mid-sized business usually takes six to twelve months from the day you start talking to buyers to the day the money moves, and the preparation before that can add a year or more. While the timeline ranges, the stages do not range, they are fixed. The stages are: preparing, finding a buyer, agreeing a letter of intent, due diligence, and closing. What stretches them is almost always the same short list: a price the market will not pay, numbers that are not ready, a seller who cannot step away from the business, and a buyer whose financing is not real. This guide walks through each stage and what moves it.
Most owners who ask how long it takes to sell a business are really asking two questions: how long until I can stop, and how long until I know whether this is going to work. The answer to both is longer than you hope and shorter than you fear.
This guide gives the typical ranges stage by stage, explains what the time is actually spent on, lists what stretches a sale and what shortens one, and ends with a plain view of the question from the buyer's side of the table, since the buyer's clock and yours run on different things.
Every figure here is a typical range drawn from how sales of businesses of this size tend to go. Your sale will differ. Treat the ranges as a planning tool, not a forecast.
The short answer: six to twelve months, plus preparation
From the first serious conversation with a buyer to the close, a sale of a small or mid-sized business typically takes six to twelve months. Sales to a buyer you already know can be quicker. Sales that go through a full marketed process, with several bidders and a long diligence period, often run toward the top of that range or beyond it.
Preparation is the part most owners leave out of the estimate. Getting the financials clean, reducing the business's dependence on you, and settling what you want can take a year or two if you start from scratch, and a few months if the company has always been run with a sale in mind. The owners who sell fastest are usually the ones who started preparing before they decided to sell.
| Stage | Typical time | What stretches it |
|---|---|---|
| Preparing the business and the numbers | A few months to two years | Messy books, owner dependence, undecided goals |
| Finding a buyer and first conversations | One to four months | An unrealistic price, a buyer list that is too long or too short |
| Letter of intent | Two to six weeks | Negotiating structure rather than price, slow attorneys |
| Due diligence | Six to twelve weeks | Unanswered requests, surprises in the numbers, bank approval |
| Purchase agreement and closing | Three to eight weeks | Landlord consents, licenses, working capital disputes |
| Transition after close | Three months to two years | Set by the deal, not a delay |
Stage one: preparing the business and the numbers
This is the stage you control, and the one that decides how long everything after it takes. A buyer will want three years of financial statements and tax returns, a current year to date, and a clear explanation of every adjustment: your salary, personal expenses run through the business, one-time costs. If those exist, this stage is weeks. If a CPA has to reconstruct them, then more time may be added to the process.
The second piece of preparation is you. A business that cannot run for a week without its owner is harder to sell and takes longer, because every buyer must work out how to replace you before they can commit (either the buyer will replace you with themselves, or they will hire a new general manager, or a mix of both). Handing authority to a manager or a small team a year before you sell shortens every later stage, and makes the business more desirable.
The third is deciding what you want. Price, timing, your role afterward, what happens to your people, what the company will stand for when it is not yours. Owners who have not settled these tend to stall at the letter of intent, because the first real offer forces the questions they had put off.
Stage two: finding a buyer and the first conversations
How long this takes depends on how you look. If you already know the buyer, a manager, a competitor, a company that has written to you, the stage can be a few weeks. If a broker or advisor runs a marketed process, expect one to four months from preparing the materials to receiving indications of interest, and longer in a slow market.
The first conversations are short and mostly about fit: what the business does, why you are selling, what you want, and how the buyer would pay for it. A serious buyer will sign a nondisclosure agreement and answer the financing question plainly. A buyer who will do neither is a buyer who will cost you time later. Our guide to who buys businesses describes what each kind of buyer will ask at this stage.
The single thing that most often stretches this stage is price. A business marketed above what buyers of its kind will pay can sit for a year while the owner waits for someone to agree. A realistic range, set with a CPA or an independent valuation, is the fastest thing you can do.
Stage three: the letter of intent (LOI)
A letter of intent sets out price, structure, timing, what happens to you and your team, and usually a period of exclusivity during which you agree not to talk to other buyers. Reaching one typically takes two to six weeks once a buyer has seen the financials and met you.
What stretches it is structure, not price. Whether part of the price is paid over time through a seller note, whether some of it depends on future results through an earnout (which may have SBA constraints), how working capital will be set at close, and what your role will be afterward are the terms that take the time. Have your attorney read the letter before you sign it; it is short, but it frames everything that follows.
Stage four: due diligence
Due diligence is the buyer's detailed check of everything the summary claimed: financials, contracts, customers, employees, equipment, leases, licenses, legal matters. It typically takes six to twelve weeks and is the stage where most sales that fail, fail.
Three things stretch it. The first is unanswered requests: a seller who is still running the company alone and answering questions at night will add weeks without meaning to. Set up a shared folder, answer in batches, and keep a log. The second is surprises: a customer concentration that was not mentioned, a revenue figure that does not reconcile, a lease that expires sooner than the buyer thought. Surprises do not usually kill a sale, but they reopen price, and reopening price adds time. The third is the buyer's financing: if a bank is lending part of the purchase price, the bank's own diligence and approval run alongside the buyer's and often set the pace. A buyer using its own capital removes that dependency, which is one reason to ask about financing on the first call.
Stage five: the purchase agreement and closing
Once diligence is substantially complete, the attorneys draft and negotiate the purchase agreement, and the parties work through the closing checklist: landlord consents, license transfers, lender payoffs, employment agreements, the working capital target. Three to eight weeks is typical.
What stretches it is usually third parties. A landlord who is slow to consent to assigning a lease, a licensing body with its own timeline, a lender who needs a payoff letter. Start those conversations as soon as the letter of intent is signed rather than when the agreement is ready.
After the close comes the transition, which is part of the deal rather than a delay: a few months to a couple of years in which you help the new owner take over. The length is agreed in the purchase agreement and depends on how much of the business was you.
What stretches a sale, and what shortens one
Across every stage the same causes recur. If you want the sale to go faster, these are the levers.
- Price: An asking range the market will not pay is the most common cause of a sale that takes two years instead of one. Set it with outside help and listen to the first three serious buyers.
- Numbers: Clean, reconciled, explained financials shorten every stage. Reconstructed ones lengthen every stage.
- Owner dependence: The more the business can run without you, the faster a buyer can commit and the shorter the transition.
- Buyer financing: A buyer paying with its own capital has fewer approvals to wait for than one relying on a bank or on raising money after terms are agreed. Ask on the first call.
- Deal structure: Flexibility on structure, within what you can afford, shortens negotiation. Rigid positions on every term lengthen it.
- Responsiveness: A seller and a buyer who each answer within a day or two close months before ones who answer within a week.
- Fit: A buyer who is the right kind of owner for the company asks fewer questions designed to find a reason to say no. That is not a stage, but it shows up in every one.
How the timeline looks from the buyer's side
We are a private holding company that buys businesses to hold, with our own permanent capital, no fund clock, and no plan to sell. From our side of the table, the slow sales are the ones where the owner has not decided what they want, and the fast ones are the ones where they have. We can move at the owner's pace, because nothing in our structure requires us to close by a date, and we can answer the financing question in one sentence, because the money is ours.
The firm is named for Colossians 3:23, "In all things, work as for the Lord and not for man", and we state that standard publicly so that the owners who sell to us can hold us to it. In practice it means we do not use the clock against a seller. A business is stewarded for the people it employs and the customers it serves, and that stewardship starts in the first conversation, not after the close. Our article on why the firm is named 323 says more.
Our record is one company long. On New Year's Eve 2024, 323 Capital acquired Midwest Information Systems, a Schaumburg, Illinois company founded in 1988 that makes PAXIT imaging software and PAXcam cameras for laboratories. The team stayed. The name stayed. We do not buy with months or quarters in mind. We buy with decades in mind.
If you are trying to work out how long your own sale might take, we are glad to give an honest view of where it would be quick and where it would be slow, with no obligation. Write to General@323cap.com, and we will reply within two business days. We are happy to sign a nondisclosure agreement first.
Questions owners ask
- How long does it take to sell a small business?
- Typically six to twelve months from the first serious buyer conversation to the close, with preparation before that adding anywhere from a few months to two years. Sales to a buyer you already know can be quicker; marketed processes with several bidders often run longer.
- What is the longest stage of selling a business?
- Usually preparation, if the numbers and the management team are not ready. Among the stages after a buyer is found, due diligence is typically the longest at six to twelve weeks and the one where most failed sales fail.
- Can a business sale close in three months?
- Occasionally, when the buyer is known, the financials are clean, the buyer is paying with its own capital, and both sides respond quickly. It is the exception. Plan for six months or more and be pleased if it is shorter.
- Why do business sales fall through?
- Most often in due diligence: surprises in the numbers, a buyer's financing that was never certain, or a seller and buyer who discover they wanted different things. Clean numbers, a plain answer about financing, and settled goals prevent most of it.
- Does selling to a holding company take less time?
- It can, mainly because a holding company buying with its own permanent capital has no bank or investor approval to wait for and no date by which it must close. The diligence is just as thorough; the dependencies are fewer.
