What business brokers charge
Main Street business brokers usually charge a success fee - a percentage of the sale price paid at closing - with a minimum fee; lower-middle-market M&A advisers often use tiered percentages and may charge an upfront retainer credited against the success fee. Few brokers publish their rates. Two that do: Empire Flippers (online businesses) charges 15% of the price up to $700,000, then 8% up to $5M and 2.5% above; Flippa charges a 10% success fee plus a listing fee. Use published schedules as a benchmark when you negotiate, and compare total cost if the deal does not close. See broker vs DIY for the fee math and our broker reviews.
How to vet a business broker in Washington
- Check the license
If your deal includes a lease assignment or real estate (most do), ask for their Washington real estate license and verify it.
- Ask for closed deals like yours
How many businesses in your industry and size range did they close in the last two years, and at what share of asking price?
- Get every fee in writing
Success-fee percentage, minimum fee, any upfront, valuation or marketing fee, and whether buyers you bring trigger the fee.
- Limit exclusivity and the tail
Listing term (6-12 months is common) and the tail period after it ends during which a sale still owes a fee.
- Know who does the work
The person who pitches you should be the person who runs your deal.
- Know your number first
Run the valuation calculator so you can judge whether a broker’s suggested price is a listing tactic.
