Someone who decides they want to buy a business, rather than start one from scratch, usually expects the process to move faster than it actually does. The logic makes sense on paper: the business already exists, it already has customers, revenue, and employees, so what’s left to figure out? In practice, buying an established business is closer to buying a house with a mortgage and a business partner attached to it than it is to a simple purchase, and the timeline reflects that.

What the Data Actually Shows
According to BizBuySell’s 2025 Year in Review, the median time to close a small business sale held at 170 days in 2025, or roughly five and a half months, measured from when a business goes to market to when the deal actually closes. That number varies significantly by industry and deal size. The IBBA and M&A Source’s Q4 2025 Market Pulse survey found that businesses priced under $500,000 tend to close in around six months, while deals in the $2 million to $5 million range often take ten months or more.
Neither of those figures includes the time a buyer typically spends searching before they even find a business worth pursuing seriously, which can add several additional months for buyers who are casually browsing rather than actively hunting.
Where the Time Actually Goes
The 170-day median isn’t one continuous negotiation. It breaks down into a handful of distinct stages, each with its own pace:
Search and initial evaluation (variable, often the longest unpredictable stretch). This is the phase where a buyer is reviewing listings, requesting information on businesses that look promising, and filtering out the ones that don’t hold up once real numbers are shared. Most buyers look at far more businesses than they ultimately pursue.
Letter of intent and preliminary agreement (roughly 2 to 4 weeks). Once a buyer identifies a business they’re serious about, this stage covers agreeing on a general price and structure before diving into detailed financial verification.
Due diligence (30 to 90 days). This is where a buyer’s accountant and attorney verify everything the seller has claimed, reviewing financial statements, contracts, leases, employee agreements, and any pending liabilities. Due diligence is consistently the stage that takes longest to predict, since the length depends heavily on how clean and complete the seller’s records are.
Financing (runs parallel to due diligence, but can extend it). A large share of small business buyers use SBA-backed loans, and lender timelines don’t always move at the same pace as the deal itself. If financing falls through partway through, it can add weeks or months to the process, or end the deal entirely.
Purchase agreement and closing (roughly 3 to 6 weeks). Once diligence is complete and financing is secured, attorneys finalize the purchase agreement and the parties move toward a closing date.
Why the Search Phase Deserves More Attention Than It Gets
Most timelines for buying a business start the clock once a buyer has already identified a specific business and made an offer. But for a first-time buyer, the search phase itself, actually finding a business worth pursuing, often takes as long as everything that follows it combined.
Buyers who go in without a clear sense of what they’re looking for (industry, size, location, price range, and how hands-on they want to be) tend to spend months evaluating businesses that were never a realistic fit. Narrowing that search early, by industry and by what a buyer can realistically finance and operate, tends to compress the timeline more than almost any other factor a buyer controls directly.
For buyers exploring what’s actually on the market in a specific region before deciding what to pursue, browsing current listings of small business for sale in Illinois gives a realistic sense of the price ranges, industries, and deal sizes available locally, which is a useful starting point before narrowing in on any one opportunity.
What Speeds the Process Up
A few factors consistently correlate with faster closings, based on industry data and how deals typically unfold:
- Clean, well-organized financial records on the seller’s side reduce how long due diligence takes, since buyers and lenders aren’t stuck reconstructing incomplete books.
- Realistic pricing from the start avoids the drawn-out back-and-forth that happens when a business is priced above what the market will support.
- Pre-qualification for financing before a buyer makes an offer, rather than starting the loan process only after a deal is agreed to.
- A narrow, well-defined search criteria on the buyer’s side, which prevents months of evaluating businesses that were never going to be a serious fit.
The Bottom Line
Buying a small business is rarely a matter of weeks. Even in a best-case scenario with a well-prepared seller and a pre-qualified buyer, six months from serious search to closing is a reasonable expectation, and it’s not unusual for the full process, including the search itself, to stretch to a year. Buyers who go in expecting that timeline tend to make better decisions along the way than those trying to rush a deal to meet an arbitrary date.
