If you own a roofing company and a private equity platform or regional consolidator has reached out, you already know the question underneath the call: what is this business actually worth, and am I about to leave money on the table? A sell-side M&A advisor exists to answer that question and then run the process that protects the answer. This guide explains, in plain terms, what does a sell-side M&A advisor do — from the first valuation conversation through the day the wire clears.
The short version: a sell-side advisor represents you, the seller, and only you. Not the buyer. Not both sides. Their job is to establish what your company is genuinely worth, create real competition for it, and defend that value through diligence and documentation so the number in the letter of intent is close to the number that actually lands in your account.
Sell-side advisor vs. business broker vs. doing it yourself
These terms get used loosely, so it helps to separate them. A business broker typically lists smaller businesses and waits for buyers to come to them — useful at the low end, but a single inbound offer is not a market. An M&A advisor for contractors (sometimes described as an investment banker for home services) runs a controlled, confidential process: they take your company to a curated set of qualified buyers at once, so the offers compete. And doing it yourself — negotiating directly with the one platform that called you — usually means negotiating against yourself with no benchmark for what fair value looks like.
Where most owners take the first offer and hope, a sell-side advisor builds a process where multiple buyers are evaluating the company at the same time. That difference is where most of the value gap lives.
What a sell-side M&A advisor actually does, step by step
Brentwood Growth runs roofing sales through a six-step sell-side process. Here is what each step means for you as the owner.
1. Readiness and value protection
Before anything goes to market, the advisor looks at your business the way a buyer will. That means a clear-eyed view of owner dependency, recurring versus project revenue, crew and subcontractor reliability, margin consistency, and how clean your financials are. The goal is to find what is quietly holding your number back — and fix what is fixable — before a buyer uses it against you. This is also where business valuation for roofing contractors happens: establishing your true free cash flow, identifying the market multiple range, and determining where your specific company sits inside that range.
2. Value framing and buyer strategy
The advisor builds the story buyers will see: how the revenue holds up, where the growth comes from, why the business transfers cleanly without you. Then they identify which buyers are the right fit — strategic acquirers, PE platforms, or regional consolidators — rather than blasting the company to anyone.
3. Controlled buyer process
This is the part owners rarely see when they go it alone. The advisor approaches qualified buyers confidentially — blind teasers that do not name your company, NDAs before any specifics are shared, and a curated buyer list. Brentwood maintains active relationships with over 3,000 private equity, institutional, and strategic buyers, so the right ones can be brought to the table at the same time. Multiple buyers evaluating at once is what turns a single offer into a real market.
4. Protecting value during diligence
After a buyer signals interest, diligence begins — and this is where deals get retraded. The headline multiple in the LOI only matters if it survives the buyer’s review. The advisor manages the data room, controls the flow of information, and gets ahead of the issues buyers typically use to chip the price down, so the deal that closes resembles the deal that was agreed.
5. Defending economics in documentation
Working alongside your attorney, the advisor defends the economics of the deal as it moves into the purchase agreement — earnouts, working capital adjustments, escrows, and the terms that quietly determine how much cash you actually walk away with. Price is only one number; the structure around it is where value is won or lost.
6. Execution and closing discipline
Through to close, the advisor keeps the process moving, manages the parties, and holds the line on what was negotiated. The job is not done at the LOI — it is done when the transaction closes on the terms you agreed to.
How an advisor fits with your CPA, attorney, and wealth advisor
A sell-side advisor does not replace your existing team. Your CPA knows your books, your attorney handles the legal documents, and your wealth advisor manages what happens to the proceeds. The M&A advisor is the business-side specialist who sits alongside them — translating your company’s performance into enterprise value, running the buyer process, and defending the economics. Owner exit planning works best when those roles are coordinated rather than improvised at the last minute.
When to bring in a sell-side advisor
You do not have to be ready to sell tomorrow to have the conversation. A readiness discussion often makes sense 12 to 36 months before you expect to go to market — enough time to find and fix what is holding your value back. And if a buyer has already approached you, that is precisely the moment to get a benchmark, because an inbound offer with no competition is the most common source of a disappointing outcome.
Whether you sell now, later, or not at all, the clarity is worth having. A complimentary business valuation is a low-commitment way to see what a buyer would actually pay — and what would need to change before they did.
Frequently asked questions
What does a sell-side M&A advisor do?
A sell-side M&A advisor represents the seller in a business sale. They establish what the company is worth, run a confidential and competitive process to qualified buyers, manage due diligence, and negotiate deal structure — with the goal of maximizing value and making sure the price agreed in the LOI is the price that survives to close.
How is a sell-side advisor different from a business broker?
A broker typically lists a business and waits for inbound interest, which often produces a single offer. A sell-side M&A advisor runs a controlled process that puts multiple qualified buyers in competition at the same time — which is what creates leverage on price and terms.
Do I need an advisor if a buyer already made me an offer?
Especially then. A single inbound offer is not a market. An advisor can run a competitive process around that buyer or test comparable acquirers to confirm whether the offer reflects fair value before you commit.
What does it cost to work with a sell-side advisor?
For sell-side representation, compensation is typically success-based — the primary fee is earned when the transaction closes, so the advisor’s incentive is aligned with getting you the best outcome.
