In the U.S., business brokers are not required to secure a small business or SBA loan from a lender. However, when a broker is involved in a transaction, a specialized escrow attorney—often called a settlement attorney—helps ensure that all parties are paid correctly, functioning similarly to a real estate closing. In the U.K., this role is handled by a commercial solicitor experienced in business transactions.

Business brokers typically operate in the lower-market segment, also known as the Main Street market, where most business sales are straightforward purchases. In contrast, investment banks, corporate finance firms, and M&A advisors handle larger, more complex transactions for mid-market companies. These deals often involve mergers and acquisitions, recapitalizations, management buyouts, or public offerings, requiring specialized skills and regulatory licensing. While business brokers and M&A firms sometimes overlap in the lower end of the market, their focus and expertise usually differ based on the size and complexity of the business transaction.
