What Happens When You Sell a Business? A Step-by-Step Guide to the M&A Process

Selling a business can feel unfamiliar, even for experienced owners.

You may have spent years building the company, managing employees, serving customers, and solving operational problems—but selling the business is a very different process.

A successful transaction typically involves valuation, preparation, buyer outreach, negotiation, due diligence, and closing.

Understanding the process early can help you make better decisions and avoid surprises.

1. Start with your goals

Before going to market, clarify what you want from the transaction.

That may include:

• A target timeline
• A minimum financial outcome
• A clean exit
• A transition period
• Continued involvement after the sale
• A strategic buyer
• A financial buyer
• A succession option

Your personal goals can affect how the business is positioned and what type of buyer may be the best fit.

2. Understand the value of the business

Before talking to buyers, establish a realistic view of what the company may be worth.

A valuation may consider:

• Revenue
• Profitability
• SDE or EBITDA
• Growth trends
• Customer concentration
• Recurring revenue
• Owner dependency
• Management depth
• Industry conditions
• Comparable transactions

The goal is not simply to arrive at a number.

It is to understand what drives value and what risks may affect buyer interest.

3. Evaluate exit readiness

A business can be profitable and still be difficult to sell.

Before launching a formal sale process, review whether the company is truly ready for buyer scrutiny.

That may include assessing:

• Financial reporting
• Customer concentration
• Owner dependency
• Key employees
• Contracts
• Systems and processes
• Operational risks
• Legal issues
• Growth consistency

Addressing these areas before buyer outreach can help reduce friction later.

4. Prepare the business for market

Once the business is ready, the next step is preparing materials that explain the opportunity clearly.

This may include:

• Historical financials
• Adjusted earnings
• Business overview
• Industry information
• Customer mix
• Growth opportunities
• Team structure
• Operations
• Competitive advantages

Buyers need enough information to understand the business while sensitive details remain protected.

5. Identify potential buyers

Different businesses attract different types of buyers.

Potential buyers may include:

• Individual entrepreneurs
• Strategic buyers
• Competitors
• Private equity firms
• Search funds
• Family offices
• Existing management
• Industry consolidators

The right buyer is not always the buyer offering the highest initial number.

Transaction structure, financing, cultural fit, certainty of closing, and transition expectations may all matter.

6. Begin confidential buyer outreach

Confidentiality is an important part of the sale process.

Owners typically do not want employees, customers, vendors, or competitors learning about a potential sale too early.

Initial outreach should usually provide enough information to generate interest without immediately identifying the company.

Interested buyers may then sign a confidentiality agreement before receiving more detailed information.

7. Review buyer interest

Once potential buyers receive information, some may request additional details or submit an initial indication of interest.

At this stage, the owner and advisor can compare factors such as:

• Proposed valuation
• Deal structure
• Financing
• Buyer experience
• Transition requirements
• Timing
• Contingencies

A higher headline price does not always result in a better transaction.

The details matter.

8. Negotiate a letter of intent

A serious buyer may submit a Letter of Intent, often called an LOI.

The LOI typically outlines the major proposed terms of the transaction.

That can include:

• Purchase price
• Cash at closing
• Seller financing
• Earnouts
• Working capital expectations
• Transition period
• Exclusivity
• Due diligence timeline

The LOI is an important milestone, but it is not usually the final purchase agreement.

9. Enter due diligence

Due diligence is where the buyer verifies the information provided about the company.

This stage can be extensive.

Buyers and their advisors may review:

Financial information

• Financial statements
• Tax returns
• Bank records
• Accounts receivable
• Debt
• Adjustments to earnings

Legal information

• Contracts
• Leases
• Corporate records
• Licenses
• Litigation
• Insurance

Operational information

• Employees
• Vendors
• Customers
• Equipment
• Systems
• Processes

Commercial information

• Market position
• Competition
• Sales pipeline
• Customer concentration
• Growth opportunities

Strong preparation before going to market can make this stage significantly easier.

10. Negotiate the final purchase agreement

If due diligence is successful, attorneys and advisors work toward a final purchase agreement.

This document outlines the legal and financial terms of the transaction.

Final negotiations may address:

• Purchase price adjustments
• Representations and warranties
• Indemnification
• Working capital
• Seller obligations
• Non-compete terms
• Transition support
• Closing conditions

This is where having experienced legal and transaction advisors becomes especially important.

11. Prepare for closing

Before closing, both sides work through any remaining conditions.

This may include:

• Financing approval
• Legal documentation
• Third-party consents
• Lease transfers
• Licensing requirements
• Employee arrangements
• Funds transfer
• Final financial adjustments

Once the required conditions are satisfied, the transaction can close.

12. Plan the transition after the sale

Closing does not always mean the owner's involvement ends immediately.

Some transactions include a transition period.

Depending on the deal, the seller may remain involved for several weeks, months, or longer.

The transition may include:

• Introducing customers
• Transferring vendor relationships
• Training the buyer
• Supporting employees
• Documenting processes
• Handing over operational responsibilities

A thoughtful transition can help protect the value of the business after closing.

How long does it take to sell a business?

There is no single timeline that applies to every transaction.

The process depends on factors such as:

• Business size
• Industry
• Financial quality
• Buyer demand
• Financing
• Due diligence complexity
• Deal structure
• Owner readiness

The sale itself may take months, but preparation should often begin much earlier.

Owners who start preparing one to three years in advance may have more time to strengthen the business before buyer discussions begin.

Should you use a business broker or M&A advisor?

The right type of advisor depends on the business and the complexity of the transaction.

Some owners need a straightforward brokerage process.

Others may benefit from a more strategic approach that includes valuation, exit readiness, buyer positioning, transaction management, and negotiation support.

NorthStar's approach is designed around helping owners understand the business first, prepare for the transaction, and then move into the sale process when the timing is right.

Preparation can influence the outcome

The best time to fix a problem is usually before a buyer discovers it.

Issues such as unclear financials, heavy owner dependency, customer concentration, or weak systems can become more difficult to address once the sale process is underway.

That is why strong M&A preparation begins before the business is formally marketed.

Thinking about selling your business?

You do not need to be ready to go to market today.

Starting with a clear understanding of your business value and exit readiness can help you determine whether the next step is to prepare, improve, or begin exploring a transaction.

NorthStar Business Advisory helps business owners evaluate their position, prepare for market, and navigate the M&A process with greater clarity.
