Is it worth hiring an M&A advisor or can you sell your business on your own? We compare both options with real data so you can make the best decision.
The big decision: do you really need an advisor?
You've built your business over years. You know it better than anyone. And now that you're considering selling, the inevitable question arises: can I do this alone?
The short answer is yes, you can. The more useful question is: should you?
Selling a business is not like selling a property. There is no published market price, no portal where you can post a listing and wait for offers. It is a complex financial transaction where information is asymmetric, confidentiality is critical, and every decision can mean hundreds of thousands of euros difference in the final price.
In this article we won't tell you what to do. We'll put the data on the table so you can decide with proper criteria.
Head-to-head comparison: selling alone vs. with an M&A advisor
Before getting into nuances, let's look at the fundamental differences between both options:
| Aspect | Selling alone | With an M&A advisor |
|---|---|---|
| Confidentiality | Hard to maintain. Everyone you contact knows you're selling. | Shielded process with blind profiles and NDAs from first contact. |
| Buyer access | Your personal network and industry contacts. | Database of qualified investors, private equity funds and family offices. |
| Valuation | Self-estimate or book value. Risk of undervaluing or setting an unrealistic price. | Professional valuation using multiple methods (DCF, comparable multiples, assets). |
| Negotiation | You face the buyer directly. High emotional component. | A professional negotiates for you, without emotional attachment and with closing experience. |
| Owner's time | 6-18 months of partial dedication. Your business may suffer. | You keep running your company while the advisor manages the transaction. |
| Due diligence | You must prepare all documentation and answer technical questions alone. | The advisor prepares the data room and guides you throughout the process. |
| Average closing time | 12-24 months (if it closes). | 6-12 months on average. |
| Direct cost | Zero (or occasional lawyer fees). | Between 1% and 6% of transaction value, depending on size. |
| Success rate | Many deals fall through due to lack of structured process. | Significantly higher thanks to a professionalised process. |
What the business owner doesn't see: the risks of selling without an advisor
When a business owner decides to sell alone, they usually think about what they save. They rarely think about what they can lose. These are the most frequent risks we observe in transactions where the seller acts without advice:
1. Undervaluation of the business
Without a professional market analysis, comparable sector multiples and intangible asset assessment, selling below real value is common. The average EBITDA multiple in Southern Europe stands at 5.3x based on 2025 data, but varies enormously by sector: from 3.8x in construction to 7.4x in software and healthcare. If you don't know your multiple, you don't know your price.
2. Confidentiality breach
Every person you tell you're selling is a risk. If the news reaches employees, suppliers or clients prematurely, the impact on the business can be devastating. An advisor works with blind profiles: the buyer sees the numbers and sector, but doesn't know which company it is until signing a confidentiality agreement.
3. Emotional and operational burnout
Selling a business is a process that lasts months. Meetings, documentation, negotiations, counteroffers, due diligence. All while still running the business. The pattern is clear: businesses whose owners get distracted by the sale lose performance, which in turn reduces the final price. It's a vicious circle.
4. Negotiating against professionals
If the buyer is an investment fund or corporate group, they'll come with a team of lawyers, financiers and consultants. You, alone. It's not a fair fight. An M&A advisor levels the playing field and knows the common negotiation tactics in these transactions.
The real cost of an M&A advisor (and why it's not an expense)
The most common objection is the price. M&A advisory fees for an SME range between 1% and 6% of the transaction value, depending on the deal size. For a business selling for 5 million euros, we're talking between €50,000 and €300,000.
It seems like a lot. But it needs context:
An advisor is not a cost, it's an investment with measurable returns. If a professionalised process achieves a 0.5x higher multiple in negotiations, for a company with €800,000 EBITDA that's €400,000 more in the sale price. The fees pay for themselves.
Moreover, most M&A advisors work with a success fee structure: they charge a percentage only if the deal closes. This completely aligns their interests with yours.
When it makes sense to sell without an advisor
We'd be dishonest if we said you always need an advisor. There are situations where selling directly can work:
- You already have an identified buyer: A partner, a competitor who has made an offer, or an employee who wants to buy the business. If the relationship already exists and there's mutual trust, you may only need a lawyer to formalise.
- Very small operations: If your company has revenue below 1 million euros, an advisor's commission may not be economically justified.
- Family succession: A transfer within the family has different dynamics that don't always require an M&A intermediary (though they do need tax and legal advice).
Outside these cases, the risk of going alone far outweighs the cost of a professional advisor.
The right question isn't "how much does it cost" but "how much are you leaving on the table"
Every business sale transaction is unique. There are no magic formulas or absolute guarantees. But there is a pattern that repeats: business owners who sell with professional advice close faster, with better terms and at a better price.
An advisor's cost is visible and quantifiable. The cost of not having one is invisible: the offer that never came because you didn't have access to that investor, the €200,000 you left on the table for not knowing your real multiple, the extra months it took to close while your business lost momentum.
If you're thinking about selling your business and your revenue exceeds 3 million euros, the question isn't whether you can afford an advisor. The question is whether you can afford not to have one.
