Should I hire an investment banker to sell my business?

Short answer: For businesses with $10M or more in enterprise value, yes. A sell-side banker runs a competitive process that almost always recovers their fee through higher price, better deal structure, or both. Owners who self-represent negotiate against professional buyers who do this daily.

What a banker actually does for you

A sell-side investment banker is not just a finder. They prepare your company for buyer scrutiny, build a competitive buyer list, manage a structured process with simultaneous offers, and negotiate every dimension of the deal simultaneously. That last part matters: price, earnout mechanics, representations and warranties, working capital peg, rollover equity terms, and indemnification caps all have economic value. A banker optimizes across all of them at once.

The core economic argument is simple: one buyer has no reason to stretch. Three or four simultaneous offers create competitive tension, and that tension is where the price premium lives. Most owners who go to market alone receive one unsolicited offer from a buyer who found them. That buyer knows they are the only one at the table.

When does the math favor hiring a banker?

The fee scale for middle-market deals typically works as follows:

• Deals under $25M: fees often run 5 to 7 percent of transaction value
• Deals between $25M and $100M: 3 to 5 percent, sometimes with a modified Lehman structure
• Deals above $100M: 1 to 3 percent, with a meaningful retainer to offset work risk

For a $30M deal, a 4 percent fee is $1.2M. If competitive tension drives bids 10 to 15 percent higher than a single-buyer negotiation would have produced, the fee is recovered on the first 5 to 6 percent of price improvement. Most bankers in structured processes drive more than that.

There is also a time argument. Running a sale process is a full-time job for six to nine months. Owners who manage it themselves typically see business performance deteriorate during the process because their attention is split. A banker insulates the business from that distraction.

When can you reasonably skip a banker?

• Your business is under $5M in enterprise value (boutique M&A brokers serve this market more cost-effectively)
• You have a single well-qualified strategic buyer who approached you, has already submitted a serious offer, and you have an independent advisor reviewing deal structure and terms
• The sale is an internal succession to family members or existing management (an MBO structure), where the process is relationship-driven rather than auction-driven
• You have a controlling private equity sponsor who has their own sale-process infrastructure

Choosing the right banker for your deal size

Fit matters more than brand. A bulge-bracket investment bank running $1B transactions has little incentive to allocate senior attention to a $40M deal. Look for boutique or regional M&A advisory firms with verifiable closed transactions in your revenue range and industry. Ask for a client reference list and call three of them. Ask specifically: did the banker stay personally engaged through closing, or did junior staff run the process after the pitch?
