You find a business to buy through four channels: online marketplaces, business brokers, direct outreach to owners who haven't listed, and your own network. The first two are where everybody else is already looking. The last two are where the good deals usually are — because the best businesses get sold before they ever show up on a site.
That's the whole answer. The rest of this is me walking through all four honestly — what each one actually gets you, what it costs you, and why the channel that feels the hardest is the one that's worth your time.
Quick scale check before we start, so you know how big the pond is. There are about 34.8 million small businesses in the U.S. And nearly half of small-business owners are 55 or older, with roughly 12 million boomer-owned businesses headed toward some kind of exit. Now compare that to what actually shows up for sale: BizBuySell, one of the biggest marketplaces, logged about 9,546 closed deals in all of 2024. Millions of owners who'll eventually sell. A few thousand listings. Most of the businesses you'd actually want to buy are not on a listing site. Keep that gap in your head — everything below comes back to it.
Channel 1 — online marketplaces and listing sites
This is where everyone starts, cause it's the easiest door. BizBuySell, BizQuest, Flippa, Acquire, the marketplace tabs on broker sites. You type in an industry and a price range and you get a wall of listings with an asking price and a blurry photo of a strip-mall storefront.
What's good about it: it's free to browse, it's instant, and it teaches you the market fast. After a weekend of scrolling you'll know what a $400k HVAC company looks like versus a $400k laundromat. The median business that actually sold in 2024 went for about $345,000 at roughly 2.6x its cash flow, and listing sites are the fastest way to calibrate your eye to numbers like that.
What's bad about it: everyone else is looking at the exact same screen. A listing that hits BizBuySell on Monday has 50 people in the inbox by Friday. The genuinely good ones get picked off fast — businesses sold in 2024 at a median of 168 days on market, but that's an average that hides the truth: the clean, well-priced, owner-not-essential ones move in weeks, and the stuff sitting at day 300 is sitting there for a reason. So you end up sorting through a lot of overpriced, hair-on-it, why-hasn't-this-sold inventory.
The other mess: the same business gets listed across 5 sites by 3 brokers at 2 different prices, and a good chunk of what you're looking at already sold and nobody took the post down. On-market is real, it's just crowded and picked-over and full of ghosts.
Channel 2 — business brokers
A business broker is the real-estate-agent equivalent for selling a company. They list it, market it, screen buyers, and run the process for a commission — usually paid by the seller. Building a relationship with brokers in your industry and geography is a legit sourcing strategy, and a lot of first-time buyers get their first deal this way.
The upside: a good broker has packaged the business for you. There's a CIM (the confidential pitch deck on the company), financials are organized, the seller is at least somewhat serious. You're not starting from a cold owner who's never thought about selling. And brokers see deals before they go fully public — if you're the buyer they trust for a certain kind of business, you sometimes get the call first.
The downside: the broker works for the seller, not you. Their job is to get the highest price and create competition. So you're back in an auction, just a more organized one. And here's the part that reframes the whole channel — most businesses that go to market with a broker don't actually sell. The often-cited number is that only 20-30% of listed businesses close. Brokers are a real channel, but they're a filtered, competitive, seller-aligned one.
Channel 3 — direct off-market outreach to owners
This is the one most people skip, and it's the one that actually moves the needle. Off-market means you go find an owner who fits your buy box and reach out — before they list, before there's a broker, before there are 50 other buyers in the inbox.
This isn't some hack. It's literally how private equity sources its best deals. Proprietary, proactive outreach — reaching owners before a process starts, before competitive pressure sets the price — is the core deal-sourcing strategy PE firms build entire teams around. They do it because the math is obvious: no auction means a fairer price and a real conversation instead of a bidding war.
And the supply is sitting right there. Remember the boomer wave — roughly 12 million businesses owned by people near retirement, and most of them have no succession plan. A huge number of those owners would sell to the right person tomorrow. They just haven't picked up the phone to a broker yet. You picking up the phone first is the entire edge.
Now the honest cost. Off-market is slow, it's a numbers game, and most owners will say no or just not answer. You have to build a target list, find the owner, send a message that doesn't sound like spam, and have the same conversation a hundred times to get a few real ones. It's grindy. But the deals you find this way are quieter, less competed, and often better priced than anything on a public listing. The trade is effort for edge.
This is also the core point of the companion piece on where the best small-business deals actually come from — the on-market pile is crowded and picked-over, and the quiet off-market lane is where the real ones live.
Channel 4 — your network, a proprietary search, and roll-ups
This is the long game, and it overlaps with off-market but it's worth its own bucket. Your network is the warmest version of channel 3 — accountants, lawyers, wealth managers, and other business owners all know companies that are quietly for sale before anyone else does. Tell 20 of them exactly what you're looking for and you've turned them into a sourcing team that works for free.
A proprietary search is the structured version: you pick one industry, go deep, and systematically contact every owner in it until you find your deal. This is the playbook self-funded searchers and search funds run on purpose, and it's the most reliable way to find something genuinely off-market — because you become the most informed buyer in a niche nobody else is grinding.
A roll-up is when you don't stop at one. You buy a business, then buy its competitors and bolt them together — same industry, more locations, one back office. It's more advanced and it's not where you start, but it's where channel 4 leads if you're building something bigger than a single owner-operator job.
The honest cost here is time. Network deals and proprietary searches don't happen on a weekend — they're months of relationship-building and outreach. But this channel produces the least-competed, best-aligned deals of all four, cause by the time something surfaces, you're often the only buyer in the room.
So what do you actually do
Don't pick one channel. Run them in parallel, but weight them right. Here's the order of operations:
- Write a buy box first. A buy box is a written set of criteria — industry, size, location, how dependent the business is on the current owner, what you'd pay. Without it, every channel just floods you with noise you can't filter.
- Use marketplaces to learn the market, not to win. Browse them daily to calibrate your eye, but assume the trophy deals are gone. They're your training data, not your main hunting ground.
- Build broker relationships for organized deal flow, knowing you're one of many.
- Spend your real effort off-market and on your network — that's where the un-auctioned, fairly-priced deals are. It's slower, but it's the part with the edge.
One more thing on the money, so the "how do I even afford this" question doesn't stop you before you start. With an SBA 7(a) loan, business acquisitions typically require around a 10% equity injection, and a chunk of that can sometimes come from a seller note rather than all cash. The capital problem is more solvable than most people assume — finding the right business is the hard part.
That finding problem is the actual reason I'm building DealStratum. It pulls the on-market listings from across the sources we track into one deduped feed you can filter down to your buy box (or browse businesses for sale by state) — so channel 1 stops being a 5-tabs-open, same-listing-three-times shit show. And it helps you reach the off-market owners — channels 3 and 4 — the people who'd sell to the right buyer but never put up a listing. It doesn't value the business for you, it doesn't lend you money, and it won't do your diligence — that part is on you and your advisors. It just makes the finding a lot less painful.
Most people see the wall of listings, figure that's the whole market, and grind the same picked-over feed everyone else is grinding. The actual market is millions of owners who haven't listed yet. The channel that feels hardest — going and finding them — is the one that's worth your time. And once you've found it, the step-by-step guide to buying a business walks you through everything that comes after.
DealStratum helps you find and source a business to buy — on-market and off. It's not a broker, a lender, or a financial advisor. Nothing here is investment or financial advice.
