Sigma Mergers & Acquisitions
At a Glance
The rare firm that answers the fee question with a number, which makes it a yardstick as well as a broker.
- Pricing
- Success Fee, The rate is on its own FAQ: 'Our success fee based commission ranges from 4% to 10%', with the trigger beside it: 'We only charge at closing so Sigma only gets paid when you get paid. There is no money paid to Sigma prior closing of your business to a buyer.' Its about page gives a second range, typically 8 to 10 percent and lower above $25 million of value.
- Best For
- Texas buyers, and anyone who wants a published percentage to measure another broker's quote against
- Kind
- One firm, one bench of brokers, one process.
- Footprint
- Names Texas. It works beyond the states it names, so one it does not name is worth asking about rather than ruling out.
- Sells
- Dallas-area businesses averaging $500,000 to $50M of annual revenue across a wide spread of industries, with over 600 sold on its FAQ and more than 700 on its home and offices pages. The site gives three founding years, two industry counts and, since the September 2026 re-read, two of its own fee ranges.
- Publishes a size band you can check yourself against.
- Seller Fee
- Publishes a schedule. The actual percentages are on its own site, so a seller's quote can be checked against them.
- Buyer Fee
- Publishes what a buyer pays. The retainers and percentages a buyer would owe are on its own site, so an engagement can be priced before a conversation.
- Publishes three buyer-representation plans with retainer bands and a success fee of two to six percent of the purchase price, plus an hourly rate for custom work.
- Works For
- Represents buyers. Names a buy-side service a buyer engages, so somebody on this list can be working for you. None of them publishes what it costs, so ask that first.
- Before It Shows You Anything
- Wants proof of funds before it shows you a business. Proof of funds or a personal financial statement, alongside the NDA. Expect to show what you can actually spend before you see a single set of books.
- An NDA with a personal financial statement, consistent with the buyer-representation plans and retainer bands the firm prices elsewhere.

Pros and Cons
Pros
- Publishes an actual commission range on its own FAQ, which almost no brokerage does
- States the payment trigger in the same breath as the rate, so both halves of the fee question are answered together
- Publishes a price band, $500,000 to $50M, a buyer can test themselves against
- Publishes what a buyer pays it as well: three representation plans with retainer bands and a success fee, which is rare on either side of the table
Cons
- Its own pages disagree on volume: the FAQ says over 600 businesses sold, the homepage says 700-plus closings
- The homepage claims its fees are significantly lower than most, with nothing behind it, beside a real published range
- Its buy-side representation is priced on a retainer you pay whether or not a deal closes, plus a success fee of 2% to 6% of the purchase price, so the firm earns more the more you pay
- Its own two pages give two rates, 4 to 10 percent on the FAQ and typically 8 to 10 percent on the about page, so ask which applies
- Its locations page carries a block copied from another brokerage's site, naming Southeastern offices that are not its own
What Searchers Say
Rate, trigger and price band read from Sigma's own FAQ. A secondhand report of an Oklahoma and New Mexico footprint did not survive a read of that page, which names Texas and Texas cities only, so this row claims Texas and nothing more.
How to Approach
Sigma Mergers & Acquisitions is a brokerage, and it works for the seller rather than for you, so this is how that side of the table comes in and what it is deciding about you.
The Typical Arc
- A teaser and an NDA, before you see the name of the business.
- A call with the listing broker, who is screening you as much as answering you.
- The CIM, then a seller meeting the broker schedules and usually sits in on.
- Your offer, carried by the broker to the seller they represent.
What It Weighs
- Whether your money is real: how much is cash, and where the rest is coming from.
- Whether your criteria are specific enough to match against a listing.
- How fast you move, because the fee arrives on a close rather than on a conversation.
