How to sell your company: a practical guide to the M&A process

Selling a company is one of the most consequential decisions a business owner will make. Whether driven by succession planning, a desire to monetise years of value creation, or a strategic decision to bring in growth capital, the process demands careful preparation, professional execution and disciplined negotiation.

Yet many business owners approach a potential sale without fully understanding how the process works, what drives value, or where the most common pitfalls lie. This guide outlines the structured M&A sell-side process that professional advisory firms follow to help business owners achieve the best possible outcome.

Why a structured process matters

Selling a company is not the same as selling a product. The stakes are higher, the timeline is longer, and the consequences of missteps are significant.

A structured sell-side process, led by an experienced M&A adviser, serves several critical functions:

Business owners who attempt to negotiate directly with a single interested buyer almost always leave value on the table. A properly run process typically engages multiple qualified buyers, whether strategic acquirers, private equity firms or family offices, and lets market dynamics determine the optimal price and terms.

The sell-side process: five key steps

A professional sell-side M&A process follows a structured framework from preparation to close. The typical timeline from start to finish is 6 to 12 months.

Step 1: Preparation and readiness assessment

Before approaching any potential buyer, the first step is to prepare the company for a transaction. This is where many sellers underinvest, and it is where the difference between a good outcome and a great outcome is often determined.

Financial preparation

Normalising the company’s EBITDA to present a clear picture of its true earning power. Owner-related expenses, one-off costs, related-party transactions at non-market rates and accounting inconsistencies should all be identified and adjusted. A well-prepared vendor due diligence package builds credibility and accelerates the process.

Operational readiness

Ensuring that the business does not depend entirely on the owner. Companies with professional management teams, documented processes and diversified customer bases command higher valuations than owner-dependent businesses.

Legal and corporate housekeeping

Resolving any outstanding disputes, ensuring all contracts and licences are current, cleaning up the cap table, and confirming that intellectual property is properly protected.

Step 2: Valuation

Understanding what your company is worth, and what drives that value, is essential before engaging with buyers. Professional valuations typically employ three complementary methodologies:

The interplay between these methodologies produces a valuation range, not a single number. Where a company falls within that range depends on its growth trajectory, market position, competitive dynamics and the level of buyer interest.

Step 3: Marketing the opportunity

Once the company is prepared and a valuation framework is established, the M&A adviser begins marketing the opportunity to potential buyers.

The breadth and quality of the buyer outreach is one of the most important value-added functions of a professional M&A adviser. A firm with strong cross-border relationships can identify and approach buyers that the business owner would never reach on their own.

Step 4: Managing the process

As buyers review the CIM and express interest, the process moves through several defined stages:

Indicative offers (IOIs) are non-binding indications of value and key terms submitted by interested buyers. The adviser evaluates these offers across multiple dimensions: price, deal structure, certainty of close, strategic fit and the buyer’s track record.

Management presentations are typically held with shortlisted buyers, giving them the opportunity to meet the leadership team and assess the business first-hand.

Due diligence is the detailed examination of the company’s financials, operations, legal affairs, tax position and commercial relationships. A well-prepared data room significantly accelerates this phase and signals professionalism to buyers.

Binding offers are submitted after due diligence, and the adviser leads negotiations on price, deal structure, representations and warranties, indemnification and closing conditions.

Step 5: Closing the transaction

The final phase involves negotiating and executing the share purchase agreement (SPA) or asset purchase agreement, coordinating with legal and tax advisers, satisfying closing conditions and completing the ownership transfer.

This phase requires careful attention to detail. Purchase price adjustments, earn-out provisions, escrow arrangements, non-compete clauses and transition service agreements all require experienced negotiation.

Common mistakes that destroy value

1. 01

   Engaging with only one buyer. Without competitive tension, the buyer controls the process and the price. Multiple qualified buyers create the negotiating dynamic that drives optimal outcomes.

2. 02

   Starting too late. Sellers who rush to market with unprepared financials, unresolved legal issues or owner-dependent operations will face discounted offers or failed processes.

3. 03

   Unrealistic valuation expectations. Expectations should be grounded in market data and comparable transactions, not emotional attachment or untested revenue projections.

4. 04

   Neglecting confidentiality. A leaked process can damage customer relationships, unsettle employees and alert competitors.

5. 05

   Losing focus on the business. If operational performance declines during the sale process, buyers will revise their offers downward.

The role of an M&A adviser

A professional sell-side M&A adviser acts as the business owner’s strategic partner throughout the transaction:

• Conducting the readiness assessment and identifying value enhancement opportunities
• Performing an independent valuation using market-standard methodologies
• Preparing professional marketing materials (teaser, CIM, management presentation)
• Identifying, approaching and qualifying potential buyers globally
• Managing the structured process from first contact through closing
• Leading negotiations on price, terms and legal documentation
• Coordinating all workstreams, including financial, legal and tax due diligence

The adviser’s mandate is to maximise the value realised by the seller while managing risk, maintaining confidentiality and ensuring the process runs on a professional timeline.

Why cross-border reach matters

For Turkish companies in particular, the buyer universe extends well beyond domestic acquirers. In 2025, foreign investors took part in about 30% of announced M&A transactions in Turkey, accounting for 55% of total disclosed deal value. European strategic buyers and North American and Gulf-based investors have all been active acquirers of Turkish businesses across a range of sectors.

An M&A adviser with strong international relationships and network access can significantly expand the buyer universe, creating more competitive tension and ultimately a better outcome for the seller.
