FAQs

Frequently asked questions about M&A Advisor costs and pricing.

How much does an M&A advisor cost?

+
M&A advisory fees include a retainer ($5,000–$30,000 depending on scope) plus a success fee (typically 2–5% of transaction value for deals under $10M, scaling down for larger deals under the Lehman formula). For a $5M sale, total fees often run $150,000–$300,000.

Do I need an M&A advisor to sell my company?

+
For deals under $1M, you may not. For deals above $2M, an experienced M&A advisor typically generates significantly more in purchase price and better terms than they cost — through competitive bidding, deal structure expertise, and keeping you from negotiating against yourself.

What is the difference between an M&A advisor and an investment banker?

+
Investment bankers at bulge bracket or mid-market firms focus on larger transactions ($50M+) and bring deep institutional buyer/seller networks. M&A advisors are often boutique or independent and are better suited for founder exits and transactions in the $1M–$50M range.

How long does an M&A process take?

+
A typical startup acquisition takes 4–9 months from initial process launch to close. Auctions and competitive processes at the higher end; proprietary outreach and single-buyer deals can move faster in 2–4 months.
