There’s no single best tool — the winning approach combines them. Marketplaces put you in a crowded auction for what’s already listed; a spreadsheet only tracks what you’ve already found by hand. A deal-aggregator platform beats both: it pulls those same marketplaces and broker sites into one feed, adds off-market outreach, and reminds you to follow up.
How each one actually performs once you’re in market — not in theory.
| Approach | Coverage | Off-market reach | Manual effort | Cost |
|---|---|---|---|---|
| Marketplaces only | On-market listings only, spread across whichever sites you check by hand — often the same business cross-posted at different prices | None — by definition, only what’s already listed | High — browse multiple sites daily and sort out stale or duplicate listings yourself | Free to browse |
| Spreadsheet | Whatever you’ve already found and typed in yourself — it stores deals, it doesn’t find them | None on its own — only whatever outreach you do separately and remember to log | High — you sort, de-dupe, and remind yourself to follow up | Cheap — the spreadsheet tool you already have |
| Brokers only | Whatever is in that broker’s book — packaged listings with financials and a CIM already organized | Some — a trusted broker occasionally calls before a listing goes public, but it’s relationship-dependent | Medium — real work to build the relationships, but the broker packages each deal for you | Commission-based, usually paid by the seller |
| Deal-aggregator platform | Marketplaces and broker sites aggregated into one deduped feed, filtered to your buy box | Built in — direct outreach to owners who haven’t listed, alongside the on-market feed | Lower — new deals are de-duped and screened automatically, with reminders on overdue follow-ups | Paid subscription — starts with a 14-day free trial |
The table above is qualitative. Here’s what it means run through one worked number.
Our own guide to buying a business puts a figure on the search itself: the rough rule of thumb is you look at around 100 deals to close 1. The question worth asking before you settle on a channel is how much of a real 100 each approach above can actually put in front of you.
Start with the size of the pool. By the off-market playbook’s own estimate, roughly nine in ten small businesses that change hands never hit a marketplace at all — they sell through a broker’s private list, a direct approach to the owner, or they don’t sell at all. That means the marketplace listings everyone’s refreshing are drawing from something closer to the remaining tenth. And even inside that tenth, some of what you’d count toward your 100 isn’t a distinct opportunity — the same listing routinely gets cross-posted at different prices across sites, so part of the review pile is duplicates wearing different price tags.
Reaching the other nine-tenths is what off-market outreach is for — but it isn’t free. Cold outreach to owners who haven’t listed commonly gets reply rates in the low single digits. Contact around 1,000 owners at that rate and you land a few dozen real conversations; only a fraction of those are open to selling, and only a fraction of that fraction survive a first look at the numbers — a handful of genuine opportunities out of a thousand contacts. That’s exactly the kind of volume a spreadsheet and a browser tab were never built to run.
| Approach | Share of the market it puts in front of you | What that means for your 100 |
|---|---|---|
| Marketplaces only | Roughly the on-market tenth — inflated further by duplicate cross-listings | Your 100 draws from a pool that’s smaller than it looks, and slow to refresh — median 168 days on market |
| Spreadsheet | Zero on its own — only what you separately source and remember to log | Your 100 is capped by however much manual outreach you can personally run |
| Brokers only | Whatever’s in that broker’s book, occasionally with a pre-list look | Real, packaged deals — but only an estimated 20–30% of listed businesses with a broker actually close |
| Deal-aggregator platform | Both slices — the on-market tenth deduped into one feed, plus outreach into the nine-tenths that never lists | Your 100 draws from the whole pool instead of a tenth of it — though the off-market slice still takes real volume to fill |
Browse BizBuySell, BizQuest, and similar sites for a few weekends and you’ll calibrate your eye fast — what a $400K HVAC company looks like next to a $400K laundromat. Just don’t expect to win there. The clean, well-priced listings move in weeks, and a lot of what’s left after the median 168 days on market is sitting there for a reason.
They’re the right primary channel for exactly one buyer: someone still pre-buy-box, mostly calibrating, not yet ready to run a real search. Go in knowing the ceiling, though — on their own, marketplaces only reach that on-market tenth from the math above, and every other buyer with a browser is looking at the same feed you are.
Keep it as long as it’s working. If you’re tracking a handful of deals you remember without looking, a spreadsheet is cheap and completely fine. Switch the moment you’re sourcing daily, juggling several brokers, or you catch yourself reviewing the same relisted business twice — that’s when the manual upkeep starts costing you actual deals.
It’s the right tool for someone still dipping into a handful of marketplace listings, not for someone running real outreach. The off-market playbook’s own follow-up cadence — a letter, a short email a few days later, another touch around day 4, a final nudge around day 9 — is exactly the kind of scheduled, multi-touch sequence a spreadsheet can store notes about but can’t actually run for you.
A good broker packages a business for you and sometimes calls trusted buyers before a listing goes public — worth having in your corner. But they’re paid by the seller to create competition, and only an estimated 20–30% of listed businesses actually close. Build the relationships; don’t make them your only channel.
They’re the strongest fit for a buyer who wants closing velocity over price tension — self-funded searchers in particular tend to lean broker-heavy, since a book with organized financials fits solo bandwidth and SBA underwriting better than a proprietary campaign does. Once a broker sends real numbers, they usually arrive as a CIM — worth remembering going in that the document is written to make the business look attractive, not audited, so screening it carefully is still on you.
When you’re sourcing daily, running conversations with brokers and owners in parallel, and need to know the moment a follow-up is overdue, a platform that pulls the marketplaces and broker sites into one feed and adds off-market outreach is doing work a spreadsheet and a browser tab were never built to do.
It’s built for the buyer who’s accepted that on-market listings are a tenth of the picture and wants the other nine-tenths without hand-building the machinery — tracing owners through public business registries and licensing boards, then running the letter-and-follow-up cadence that gets cold outreach actually answered. That work is real either way; a platform just runs it in the background instead of on your weekends.
Don’t rely on one channel. The strongest searches run marketplaces, broker relationships, and direct off-market outreach in parallel, weighted toward off-market since that’s where the least-competed deals are — and track all of it in one place so a promising conversation doesn’t quietly go cold while you’re focused elsewhere.
They’re a good place to start and a bad place to stop. Marketplaces are free, instant, and the fastest way to learn what businesses in your price range actually look like. But everyone else is looking at the same listings, the good ones get picked off within weeks, and a lot of what’s left is overpriced, stale, or already sold with nobody taking the post down.
Early on, yes. If you’re tracking a handful of deals you can hold in your head, a spreadsheet is cheap and completely workable. It breaks down once you’re sourcing daily and juggling multiple brokers, because it can’t find deals on its own, can’t tell you when the same business has been relisted by a different broker, and won’t remind you when a follow-up is overdue.
Broker relationships are worth building, but not as your only channel. A good broker packages the business for you — organized financials, a real CIM — and occasionally calls trusted buyers before a listing goes public. The catch is the broker works for the seller, not you, and is paid to create competition. It’s also worth knowing that most listed businesses with a broker don’t actually close — the often-cited number is 20–30%.
Sourcing plus tracking in the same place. A platform pulls live listings from the marketplaces and broker sites it tracks into one deduped feed filtered to your buy box, adds direct outreach to owners who haven’t listed, and reminds you when a broker or owner reply is overdue — three things a browser tab and a spreadsheet were never built to do.
Less than most buyers assume. The off-market playbook’s own estimate is that roughly nine in ten small businesses that change hands never appear on a marketplace at all — they sell through a broker’s private list, a direct approach to the owner, or they don’t sell at all. Marketplaces show you the remaining tenth. That’s not a reason to skip them — they’re free, real-time market education — but it’s a reason not to stop there if reach is what you actually need.
Screen it fast, before you fall for it. If a broker’s involved, the first real document you’ll get — after signing an NDA — is a confidential information memorandum, or CIM. It’s worth knowing going in that a CIM is a marketing document written to make the business look attractive, not an audited financial, and the projections inside are the seller’s case for the business, not a guarantee. Pull the actual cash flow, check the add-backs, and treat everything else as the pitch it is.
For the deeper version of any of this: how to find a business to buy past the listing sites, where the best small-business deals actually come from, or deal platform vs. spreadsheet, dimension by dimension.
