How to Value and Sell Your Business: The Complete Guide

You've spent decades building your business and pouring your life into it. Selling it will likely be the biggest personal and financial decision you ever make. The good news is that how to sell a business isn't a mystery. It follows nine predictable steps, and most sales close within six to 12 months once a buyer is involved.

This guide walks through the full process from start to finish: how to figure out what your business is worth, how to increase its value before you sell, and how to choose a buyer who will take care of what you've built. You can also download our Seller's Checklist to work through each step at your own pace.

Key takeaways

• Start preparing to sell one to three years before you want to sell. The best time to sell is when you don't have to, so you won’t be pressured to take the first offer you get.
• Buyers pay a multiple of EBITDA and steady results matter more than one strong year.
• The less your business depends on you and other owners, the more it's worth.
• The highest offer isn't always the best one. Weigh terms, the buyer's ability to close, and what happens after you sell.
• Ask every buyer whose capital they are using, how long they'll own the business, and who will run it after you.

What to know before you start

This guide is for owners of established service and B2B businesses who are asking "How do I sell my business?" and thinking about a sale in the next one to five years. Maybe you're planning to retire, want to take a step back, or just want to understand your options before a buyer comes calling.

At SIG Partners, we've completed more than 38 ownership transitions and paid owners more than $340 million over the last five years. This experience has taught us what separates a smooth sale from a stressful one.

A few things to know as you read:

• Timing: most sales take six to 12 months once a buyer is involved, but the best outcomes usually feature business owners who started preparing one to three years earlier.
• Structure: the nine steps below follow our Seller's Checklist, so you can track your progress as you go.
• SIG's approach: several steps end with a short note on how SIG handles that part of the process. You don't need to sell to us for this guide to be useful. It's written to help any owner sell well.

Let's get into the step-by-step process.

Step 1: Decide why, when, and what you want

Before you talk to a single buyer, get clear on three things: why you want to sell, when you want to sell, and what matters most to you during the process. Owners who skip this step often end up reacting to the first offer instead of choosing the right one.

Why you're selling: Common reasons include retirement, burnout, health, a family change, or wanting to turn years of work into financial security. Your core reason shapes all of the decisions you will make during the process. An owner ready to retire in a year needs a different plan and needs a different buyer than one who wants to stay on and help the business grow.

When to sell: The best time to sell your business is when you don't have to. When your business is strong, you aren't under any financial pressure, you have time to prepare, compare buyers, and walk away from a deal that isn't right. Owners who wait until burnout or a health scare forces a sale often accept less and have little say in who takes over.

What you want beyond price: Write down your non-negotiables now, before emotions and offers get involved:

• How important is it to you that all of your employees keep their jobs after the transition?
• Is it important that the company brand stay the same?
• Do you want to leave the business completely at closing, stay for a transition, or stay long term?
• How much do you need to walk away with after taxes? A financial planner can help you find that number.

Talk these through with your spouse, family, and any partners so everyone is aligned before your conversations turn into real negotiations.

How SIG approaches this
SIG works with founder-led businesses, typically $4 million or more in annual revenue, whose owners care about what happens after the close. Our first conversation is about your story and your goals, not a price. It's confidential, with no obligation.

Step 2: Get your financials buyer-ready

Buyers will only make a serious offer if you have years of earnings that can be verified. Clean, consistent financials are the single biggest factor in a smooth sale, and messy books are one of the most common reasons deals fall apart or prices drop late in the process.

If you're wondering how to sell my business for the best price, start here:

• Gather three years of financial statements (profit and loss, balance sheet, and cash flow) and make sure they match your tax returns.
• Move to accrual accounting if you're on a cash basis. Accrual accounting shows a truer picture of finances, as it tracks when revenue is earned and costs are incurred, not just when cash changes hands.
• Separate all personal and business expenses. List any add-backs, like a personal vehicle or one-time legal fee, with receipts to support each one.
• Break down your revenue by customer and by recurring versus one-time work. Service agreements and repeat contracts are among the most valuable things a buyer can see.
• Consider a sell-side Quality of Earnings review. An outside accountant reviews your numbers the way a buyer would, so you can find and fix problems before a buyer finds them.

This is also where you'll calculate the earnings number your price will be based on, either SDE or EBITDA. Our EBITDA vs. SDE guide walks through both with a worked example.

How SIG approaches this
SIG looks for stable year-over-year results and modest growth, not one standout year. Like most serious buyers today, we care about how durable your earnings are over several years.

Step 3: Make the business run without you

A buyer is paying for a business that will keep running after you leave. The more your business depends on you, the riskier it looks to a buyer and the less they'll pay.

Ask yourself: could you take two weeks off without your phone ringing with a crisis that only you can solve? If not, here's where to focus:

• Build a second in command. A general manager, operations lead, or long-time foreman who can make day-to-day decisions is one of the most valuable assets you can have when selling.
• Document how things get done. Write down your core processes, like pricing jobs, dispatching crews, ordering supplies, and onboarding customers, so someone else can follow them.
• Hand off relationships. Introduce your team to key customers and vendors now, so those relationships aren't tied only to you.
• Reduce customer concentration. If one customer makes up a large share of revenue, buyers see risk. Aim for no single customer above roughly 10–20% of sales and your top five customers coming in under 40%.

Buyers ask “how do you sell a company that runs on one person's knowledge?” Usually at a discount. The work you do here pays off directly in your price.

How SIG approaches this
The one deliberate change SIG makes is at the top. At closing, we bring in a full-time CEO with 15+ years of operating and industry experience who relocates to lead the business. That means you don't need to hire your own replacement before selling. Your job is to document what lives in your head so it can be handed off.

Step 4: Organize legal and business documents

Every buyer will ask for the same core documents during due diligence. Having them organized before you go to market shortens the timeline and shows a buyer you run a tight ship, which builds trust before an offer is ever made.

Gather these now:

• Corporate records: formation documents, ownership records, and operating or shareholder agreements
• Contracts: customer and vendor agreements. Look for change-of-control clauses that require consent to transfer.
• Real estate: leases or deeds, and whether a lease can transfer to a new owner
• Licenses and permits: everything required to operate, plus any certifications
• Insurance: current policies and claims history
• Employees: handbook, benefits plans, key employee agreements, and any open HR issues
• Disputes: any pending litigation, liens, or open claims

If something is missing or messy, like an expired license or an unsigned contract, fix it now. Surprises in diligence are one of the fastest ways to lose leverage when you sell a business.

Step 5: Understand what your business is worth

Most owners have a number in mind. Buyers arrive at theirs with a simpler formula:

Earnings × multiple = estimated value

The earnings number is usually adjusted EBITDA, which is standard for more mature businesses with a solid foundation. The multiple reflects how much risk a buyer sees and how much growth they expect. Two businesses with the same earnings can sell for very different prices because of it:

The market matters too. Multiples rise and fall with interest rates, buyer demand, and the economy. Small business EBITDA multiples have fallen from roughly 6.7× at a 2017 peak to around 4.3× in 2025 as buyers have become more choosy when making deals.

Price isn't the whole story, though. How you're paid the closing price changes what you take home. An offer might include cash at closing, seller financing (part of the price paid to you over time), or an earnout (part of the price tied to future results). A slightly lower offer that's mostly cash at closing can be worth more than a higher one with strings attached.

Before you go to market, get a professional valuation. It sets realistic expectations, shows you where you can raise your value, and helps you recognize a fair offer when you see one. Understanding value is one of the most important parts of learning how to sell a business well.

Step 6: Choose your advisors and the right type of buyer

Build your team first. Selling a company involves legal, tax, and financial decisions that most owners only face once. At minimum, you'll want:

• An M&A attorney who handles business sales regularly (not just a general attorney)
• A CPA who can provide tax implications of different types of sales before you go too far down any road
• A wealth manager or financial planner to plan for life after the sale

Many owners also work with a business broker or investment banker. A good one can market your business widely, create competition among buyers, and manage everything so you can keep running the company during the sales process. Others sell directly to a buyer they already know or who approaches them. Both paths can work. The right choice depends on your size, your timeline, and how much of the process you want to manage yourself.

Then think about who you want to sell to. When conversations start, you'll likely hear from several types of buyers:

• Competitors or strategic buyers who want to combine your business with theirs
• Private equity firms that invest from a fund and typically plan to sell within several years
• Search funds and first-time buyers looking to buy and run a business themselves
• Long-term holding companies that buy businesses to own indefinitely
• Family members or your management team

Each can be the right fit for a different owner. What matters is knowing what each one plans to do after closing. These questions are very important to get answered and work with any buyer:

1. Whose money is it, and is there a fund with a deadline?
2. How long do you plan to own the business?
3. Who will run it after I leave?
4. What happens to my employees and our company name?
5. What support will the business get after closing?
6. Can you show a record of closing deals on the terms you offered?

Here's how SIG answers them, compared with a typical fund-backed buyer:

Step 7: Evaluate offers and sign an LOI

When buyers get serious, offers usually come in two stages:

• An IOI (indication of interest) is an early, non-binding offer, often a price range, that shows who's serious.
• An LOI (letter of intent) is a more detailed, mostly non-binding agreement on price and key terms. Signing one usually gives the buyer an exclusive period to complete due diligence.

Before sharing detailed financials with anyone, require a signed NDA (non-disclosure agreement) to keep your sale confidential.

When you compare offers, look past the headline number:

• Structure: How much is cash at closing, and how much is deferred through seller financing or an earnout?
• Timeline: How quickly can the buyer close, and what could delay it?
• Conditions: What would allow the buyer to walk away or lower the price?
• Certainty of closing: Does the buyer have committed capital, and have they closed similar deals on the terms they offered?

That last point matters more than many owners expect. A high offer from a buyer who can't close isn't a better offer. It's a lost few months and a business that's been off the market. Knowing how to judge the close is one of the most important parts of selling a business. And as with every step, review any LOI with your attorney before you sign.

How SIG approaches this
SIG's promise is certainty of closing on the terms we agree to. We've completed 35+ ownership transitions and paid owners $315 million over the last five years.

Step 8: Get through due diligence and closing

Due diligence is the buyer verifying everything you've told them. It typically takes 60 to 120 days after the LOI is signed. Being organized is the best way to sell a business quickly without cutting corners.

What buyers will review: your financials (often through a Quality of Earnings review), contracts, licenses, equipment, employees, customers, and any legal issues. The documents you gathered in Steps 2 and 4 become your data room, a secure online folder the buyer can access.

How to keep things on track:

• Assign one point person to respond to buyer requests quickly.
• Keep running the business at full speed. Results during diligence matter, and a dip can reopen price discussions.
• Negotiate the purchase agreement carefully. This is the final, binding contract. It covers representations and warranties (what you promise is true about the business), indemnification (who pays if something turns out to be wrong), and working capital (how much cash and inventory stays with the business at closing).
• Plan your announcement. Decide when and how to tell employees, customers, and vendors. Usually that's close to or at closing, with the buyer's input.
• Finalize your tax plan with your CPA before closing, not after.

How SIG approaches this
SIG runs a clear process and timeline, stays involved through diligence, and works closely with sellers' brokers and attorneys. As one former owner put it: "We trusted them to do what they said they would do."

Step 9: Plan the transition and life after the sale

Closing isn't the finish line. How you hand off the business protects your employees, your customers, and your legacy, and it makes the change easier on you.

• Put your role in writing. Agree on how long you'll stay, how many hours, and what you'll be responsible for. Some owners leave at closing. Others stay for a few months to introduce the new owner and pass along what they know.
• Hand off relationships. Personally introduce the new leadership to key employees, customers, and vendors.
• Transfer what lives in your head. Pricing history, supplier quirks, customer preferences. The more you pass along, the smoother the first year goes.
• Plan for yourself, too. Many owners underestimate how much of their identity is tied to the business. Think about how you'll spend your time, and who you'll spend it with, before your last day.

When you sell your business to the right buyer, this step should feel like passing the keys to someone you trust, not walking away from something you built.

How SIG approaches this
With SIG, you transition out over 90 days on your terms. The brand stays, the team stays, and day-to-day operations don't change. Each company gets an Operating Partner and a three-person board: the CEO, a founding partner, and an operator from the same industry. We invest in growth through sales, marketing, and pricing, not cost-cutting.

How long does it take to sell a business?

Most sales take six to 12 months once a buyer is involved, plus the preparation time before that:

Timelines vary by business size, industry, and buyer.

If you're wondering how to sell your business fast, the biggest levers are preparation and buyer choice. Clean financials and organized documents shorten diligence. Buyers with committed capital and a clear process can move faster than those still arranging financing.

Frequently asked questions

How do I sell my business?
Start by getting clear on your goals, then prepare your financials, reduce how much the business depends on you, and organize your documents. From there, understand your value, choose your advisors and buyer, compare offers, get through due diligence, and plan your transition. Our Seller's Checklist walks through all nine steps.

How much can I sell my business for?
Most businesses sell for their EBITDA multiplied by a number that reflects risk and growth. Size, industry, recurring revenue, and how much the business depends on you all move that multiple. A professional valuation gives you a realistic range.

How long does it take to sell a business?
Most sales take six to 12 months once a buyer is involved: a few months to find buyers and receive offers, a few weeks to sign an LOI, and 60 to 120 days of due diligence. The best outcomes usually start with one to three years of preparation.

Should I use a business broker?
It depends on your size, timeline, and goals. A good broker can market your business widely, create competition among buyers, and manage the process. Some owners sell directly to a buyer they already know. Either way, you'll want an M&A attorney and a CPA involved early.

How is the sale of a business taxed?
It depends on how the deal is structured, especially whether it's an asset sale or a stock sale, and how you're paid over time. The difference can be significant, so involve a CPA before you sign an LOI. This guide isn't tax advice.

Can I sell my small business online?
Yes. Online marketplaces can put your business in front of many buyers quickly. But more buyers doesn't always mean better ones. Screen every buyer for committed financing, a record of closing deals, and a clear plan for running the business after you leave.

Plan early, and choose your buyer carefully

Selling your business doesn't have to be overwhelming. Start early, get your financials and documents in order, and make the business less dependent on you. Understand what it's worth before you go to market. Most importantly, choose your buyer as carefully as you negotiate your price. The right buyer can close on the terms they offer and will take care of what you've built.
