What Does an M&A Advisor Cost — And When Is It Really Worth It?

What Does an M&A Advisor Cost — And When Is It Really Worth It?

Selling a company is a multifaceted process — legally demanding, financially complex and often emotionally charged. To structure this transaction process in an organised, efficient and legally sound manner, many business owners engage professional M&A advisory.

But many ask themselves: what does an M&A advisor cost in a business sale? And when does this investment really pay off?

Fee Models at a Glance: What Does an M&A Advisor Charge?

In practice, M&A advisors typically work with a tiered fee model consisting of three components: the so-called retainer (a monthly advance payment), the success fee (a performance-based commission) and, where applicable, additional fees for specific services such as Due Diligence support or international buyer searches.

The retainer is generally between EUR 5,000 and EUR 100,000 per month, depending on the scope of the project and the advisor's profile. However, not every M&A advisor charges a retainer — particularly at highly specialised M&A firms or advisory houses. In such cases, the fee model is often structured solely around the success fee, which reduces the risk for the client.

The success fee is based on the achieved purchase price and often amounts to between 2% and up to 17%, particularly for smaller-volume transactions. For large-volume transactions of approximately EUR 100 million and above, the success commission is proportionally lower, but remains high in absolute terms.

Cost and Benefit in Proportion: Is an M&A Advisor Worth It?

The costs of M&A advisory appear considerable at first glance. In practice, however, the investment frequently pays for itself multiple times over. A competent M&A advisor brings additional buyers to the table, positions the company strategically, improves the deal structure and maximises the net sale proceeds.

Tax optimisation, liability limitation or a clever earn-out structure can be financially decisive. M&A advisors who have accompanied many transactions recognise optimisation opportunities early and provide impetus regarding the choice of legal structure, holding periods or the design of disposal proceeds — always in coordination with tax advisors and lawyers.

Why Retainers Are Common in Early Phases

Particularly in the early phase — during company analysis, document preparation, market positioning and buyer outreach — the retainer is prevalent. In the mid- to large-cap segment from approximately EUR 50 million in company value, it also serves to offset the high resource expenditure in the first months.

In this phase, the advisor develops individual marketing strategies, engages specialist personnel and lays the foundation for a successful bidding process.

Large Investment Banks vs. Specialised M&A Boutiques

Depending on the size and complexity of the transaction, the right contact partner varies:

Investment Banks

For cross-border transactions with volumes above EUR 100 million, large investment banks offer global buyer reach and high transaction frequency.

Specialised M&A Boutiques

For company values between EUR 5 million and EUR 100 million, specialised M&A boutiques are often more suitable. They work in close proximity to their clients, with an industry focus and flexibly. Often owner-managed, they offer direct points of contact and quick decision-making. Many focus on sectors such as industry, healthcare, IT or consumer goods.

When an M&A Advisor Is Not Worth It: Examples from Practice

In certain cases, an M&A advisor can be dispensed with — for example in the case of:

• very small companies (revenue below EUR 200,000)
• time-critical distressed sales
• intra-family succession solutions
• sales to known business partners
• liquidation processes or sole traders with little intangible value

Caution is also advised in such cases: a lack of expertise can lead to strategic errors that cost more than the advisory fees saved.
