The Complete Seller's Guide

How to sell your business

For most owners, selling the company you built is the biggest financial decision of your life, and you only get to do it once. This is the plain-English guide to doing it right: when to sell, what it's worth, who to hire, how the process works, and how to keep it confidential.

Is your business ready to sell?

The best time to sell is rarely the moment you decide you want out. It's earlier, while the business is still growing and doesn't lean entirely on you. Buyers pay up for momentum. The strongest sales happen from a position of strength, not exhaustion.

A few signs you're in a good window to consider selling a business:

  • Steady or growing revenue. Buyers underwrite the future, and recent growth is the clearest evidence of it.
  • The business runs without you. If you can take a two-week vacation and nothing breaks, your business is far more sellable.
  • Clean, current financials. Reviewed books and clearly documented owner add-backs survive a buyer's scrutiny.
  • Favorable conditions in your industry. When buyers are active in your sector, you have more leverage and more competing offers.
  • A personal reason that won't wait. Retirement, health, burnout, a new venture. All valid reasons, but plan around them rather than reacting to them.

On when to sell your business: the honest answer is that planning should start a year or two before you actually go to market. Most of what raises your price takes time to fix. Reducing customer concentration, cleaning up the books, building a management layer underneath you. Start early and you sell on your terms. Start late and you take whatever the market gives you.

What's your business worth?

Almost every small and lower-middle-market business is valued the same way: a measure of profit multiplied by an industry multiple. Owner-operated businesses use Seller's Discretionary Earnings (SDE). Larger ones with a management team use EBITDA. The multiple is where industry, size, growth, and risk all get priced in.

Get an indicative range in seconds with our free business valuation calculator, then see how multiples vary across sectors in our EBITDA & SDE multiples by industry report. A calculator orients you. It doesn't replace an advisor who reviews your actual numbers against what buyers are paying right now.

Who you hire: broker vs M&A advisor vs investment bank

The professional you choose depends mostly on the size of your business, and the choice affects both your final price and how smoothly the deal goes. We cover this in depth in business broker vs M&A advisor, but here's the short version.

Business broker

Brokers typically handle smaller, owner-operated businesses: main-street companies and the lower end of the market. They list, market, and help negotiate the sale. For a straightforward sale of a smaller business, a good broker is often the right fit.

M&A advisor

M&A advisors work the lower-middle-market: more complex deals, wider buyer pools that include strategic acquirers and private equity, negotiations with more moving parts. They run a structured, competitive process built to drive up price and protect your terms. That's the work most owners can't do alone.

Investment bank

Investment banks handle the largest transactions, where buyers are institutional and deal structures get sophisticated. For most owners reading this, a broker or M&A advisor is the realistic choice.

How you pay them: retainer vs success fee

Most advisors are paid a success fee, a percentage of the sale price paid only when the deal closes. The percentage generally shrinks as deal size grows. Some firms also charge an upfront retainer to cover the work of preparing and marketing the business. Others work success-only with no retainer and take on that upfront risk themselves. Neither model is automatically better, but a no-retainer arrangement ties the advisor's pay to your outcome and lowers your cost of finding out what's possible. ProCloser can match you with vetted firms that include no-retainer options.

The process & timeline

A sale runs through a recognizable sequence of stages. Knowing the map ahead of time keeps you from being surprised, and from negotiating against your own interests.

StageWhat happens
1. PrepareClean financials, document add-backs, reduce owner dependence, fix obvious risks.
2. ValueSet an indicative range from earnings multiples and current comps.
3. MarketBuild a blind, anonymous teaser to attract qualified buyers.
4. NDA + CIMBuyers sign an NDA, then receive the Confidential Information Memorandum.
5. LOIBuyers submit Letters of Intent; you negotiate price and terms and pick one.
6. Due diligenceThe buyer verifies everything. Organized records keep this phase short.
7. CloseAttorneys finalize the agreement, funds move, ownership transfers.

How long does it all take? That depends on size, industry, and how prepared you are. As a rough guide, most lower-middle-market deals take several months to about a year from going to market through close. Preparation is the biggest lever on speed. A drawn-out due diligence phase is the most common reason a timeline stretches. Treat these as qualitative expectations, not promises. For a step-by-step prep list, see our selling a business checklist.

Keeping the sale confidential

One of the biggest fears owners have is that employees, customers, or competitors will find out the business is for sale before it's done. They shouldn't have to. Confidentiality is standard practice in a well-run M&A process, and it works on three layers:

  • The blind teaser. Buyers first see a one-page anonymous summary: industry, size, and a few highlights, with nothing that identifies you.
  • NDA first. A buyer signs a non-disclosure agreement before they ever learn the company's name or see detailed financials.
  • No public listing. A serious lower-middle-market sale isn't posted on a public marketplace with your logo on it. Information flows through a controlled, advisor-managed process.

Done right, the people who need to know find out on your schedule, not from a rumor.

Documents you'll need

A handful of documents do most of the work in a sale. You don't have to draft them yourself. Your advisor and attorney handle that. But you should recognize them:

  • NDA (Non-Disclosure Agreement). Signed by buyers before they receive confidential details.
  • CIM (Confidential Information Memorandum). The in-depth document that tells your business's full story to qualified, NDA-signed buyers.
  • LOI (Letter of Intent). The buyer's non-binding outline of price and key terms, and the starting point for serious negotiation.
  • APA (Asset Purchase Agreement). The binding contract that actually transfers the business at close (or a stock purchase agreement, depending on structure).
  • Earnout. A provision where part of the price is paid later, tied to the business hitting agreed targets. It's common when buyer and seller disagree on future performance.

Taxes, at a high level

How a deal is structured has a large effect on your after-tax proceeds: an asset sale versus a stock sale, how the price is allocated, whether there's an earnout. Two offers with the same headline number can leave very different amounts in your pocket once taxes are accounted for.

That's exactly why this guide won't give you specific tax advice. The right answer depends on your entity type, your basis, your state, and your personal situation. Bring a CPA or tax advisor in early, before you sign an LOI rather than after, so deal structure is planned with the tax outcome in mind. Good tax planning at the structuring stage routinely changes net proceeds more than another round of price haggling would.

Common mistakes to avoid

  • Going to market unprepared. Messy books and an owner-dependent operation invite low offers and failed diligence.
  • Pricing on emotion. What the business is worth to you isn't what a buyer will pay. Anchor on the market, not your memories.
  • Breaching confidentiality too early. A leak can cost you employees, customers, and leverage.
  • Negotiating alone. Buyers do this for a living; without an advisor running a competitive process, you're outmatched.
  • Taking your eye off the business. A sale takes months. If performance dips during due diligence, the buyer will renegotiate down, or walk.

Frequently asked questions

How long does it take to sell a business?

It varies with size, industry, and how ready your business is. Most lower-middle-market deals take several months to about a year from going to market through close. Preparing your financials and reducing owner dependence ahead of time is the biggest lever on speed, and a slow due diligence phase is the most common reason timelines stretch.

Do I need a broker or an M&A advisor?

It depends on size. Brokers typically handle smaller, owner-operated businesses. M&A advisors and investment banks handle larger, lower-middle-market deals with wider buyer pools and more complex negotiations. The right professional has closed deals at your size, in your industry, recently. See business broker vs M&A advisor for the full comparison.

How much does it cost to sell a business?

Most advisors charge a success fee, a percentage of the sale paid only when the deal closes, and that percentage usually shrinks as deal size grows. Some add an upfront retainer. Others work success-only with no retainer. Budget separately for legal counsel and a CPA. ProCloser is free to sellers and can match you with no-retainer firms.

How do I keep the sale confidential?

Confidentiality is standard in M&A. Your advisor markets with a blind, anonymous teaser, requires buyers to sign an NDA before they learn your identity, and releases detailed information only through a controlled process. There's no public listing with your name on it.

What's my business worth?

Most businesses are valued on an earnings multiple: your annual profit (SDE for smaller, owner-operated businesses or EBITDA for larger ones) times a multiple reflecting industry, size, growth, and risk. Start with our free valuation calculator for an indicative range, then get it reviewed.
