Buy-side advisor

A buy-side advisor is a professional engaged by a buyer to help find, evaluate, negotiate and close an acquisition. Unlike a listing broker, who is paid by and represents the seller, a buy-side advisor’s duty runs to the buyer throughout the search and the deal.

Reviewed

Most business brokers work for the seller — their fee comes from the sale proceeds, and their job is to get the seller the best price and terms. A buyer with no representation is negotiating against a professional with none of their own, which is the gap a buy-side advisor is engaged to close.

What a buy-side advisor typically does

  • Helps define and refine the buyer’s buy box and sources opportunities that match it
  • Reviews financials and prepares the buyer’s questions ahead of formal due diligence
  • Advises on offer structure, valuation range and negotiating strategy
  • Coordinates with the buyer’s lawyer and accountant through to closing

How they are typically paid

Fee structures vary — a flat retainer, an hourly rate, a fee tied to the size of the deal that closes, or some combination. The terms should be agreed and put in writing before the search begins, the same way a seller would agree a listing agreement with their own broker.
