The short answer: Businesses for sale come from three channels, online marketplaces (BizBuySell, BizQuest, BizScout, Baton), business brokers who list Main Street deals, and off-market outreach where you contact owners directly. BizBuySell is the largest, with tens of thousands of active listings, but the best deals often trade before they're ever posted. Serious buyers run all three channels at once with a clear buy-box and a repeatable system so they review more deals and compete for fewer of them.
The three ways to find a business
Every acquisition starts the same way: you have to see the deal before you can buy it. There are only three doors deals come through, and each has a different trade-off between volume, competition, and effort.
| Channel | What it is | Competition | Effort |
|---|---|---|---|
| Marketplaces | Public listing sites you browse and set alerts on | High | Low |
| Brokers | Intermediaries who represent sellers and send you deals | Medium | Medium |
| Off-market | You contact owners directly, before they list | Low | High |
Beginners tend to live on marketplaces because they're easy. The problem is everyone else is there too, a good listing can draw dozens of buyers in a week. The buyers who win consistently add off-market sourcing and strong broker relationships so they aren't fighting the crowd for the same handful of deals.
The deal you win is rarely the one everybody saw. It's the one you found first.
When I bought my first business, I stopped refreshing marketplace tabs and started emailing owners directly. My reply rate was ugly at first, but the deals I did get had almost no other buyers at the table, and that's where the leverage is.
Start with a buy-box, not a marketplace
The biggest mistake new buyers make is searching before they've decided what they're searching for. A buy-box is your written filter: the industry, size, location, and cash-flow profile of a business you'd actually buy. Without it, every listing looks interesting and none of them get pursued.
A simple buy-box template
Industry: home services (HVAC, plumbing, electrical). Location: within 90 minutes of me. Price: $500k, $1.5M. Cash flow (SDE): $200k, $400k. Owner: willing to stay 60 to 90 days for transition. Anything outside the box gets a fast no.
A tight buy-box is what turns sourcing into a system. It tells you which marketplaces to watch, what to tell brokers, and exactly who to reach out to off-market. Then you can score every deal against the same standard instead of falling for the first shiny listing.

Frequently asked questions
Three places: online marketplaces (BizBuySell, BizQuest, BizScout, Baton), business brokers who list Main Street deals, and off-market outreach where you contact owners directly. Most serious buyers work all three at once.
BizBuySell has the most listings and traffic, so it's the default starting point. BizQuest, BizScout, and Baton each add something different. No single site has every deal, see the full comparison.
Direct outreach: pick an industry and area, build a list of owners nearing retirement, and contact them with a short, respectful message. It's slower than a marketplace but far less competitive. See off-market sourcing.
For most self-funded buyers, 6 to 12 months from serious search to signed letter of intent. It depends on how tight your buy-box is and whether you build steady deal flow.
