Most owners price their sale timeline the way they’d price a home sale: list it, field a few offers, close in 60 days.
That’s not what happens.
According to BizBuySell’s 2025 Year in Review, the median time from listing a small business to closing the sale was 170 days — about 5.6 months. That’s the middle of the range. Plenty of deals run longer, especially once a buyer’s financing enters the picture.
If you’re planning your exit, or even just curious what selling would actually involve, the timeline matters as much as the price. An owner who thinks they’re 90 days from a check is going to make different hiring and spending decisions than one who knows it’s closer to 8 months.
Here’s what actually eats the time.
The Four Stages That Make Up the Timeline
Take a hypothetical $1.1M commercial cleaning company doing $290K in SDE (seller’s discretionary earnings — basically the total financial benefit to an owner-operator, salary plus profit plus perks, before a buyer’s overhead is layered on).
Prep (4-12 weeks, sometimes longer). Clean financials, a defensible add-back schedule, a confidential information memo. Owners who’ve kept tight books can move through this in a month. Owners with cash-basis accounting, commingled personal expenses, or no formal financials often need two to three months here alone — and rushing it usually shows up later as a lower offer or a diligence fight.
Marketing to signed LOI (60-120 days). This is the stretch most owners underestimate. It’s not one buyer saying yes. It’s dozens of inquiries, a handful of serious conversations, several rounds of information requests, and usually more than one offer that falls apart before you get to a signed letter of intent. A clean, well-priced deal can move faster. A business with concentration risk, thin margins, or an inflated asking price can sit for six months or more before the right buyer shows up.
Due diligence (30-60 days). Once the LOI is signed, the buyer’s team goes through financials, contracts, employee records, and operations line by line. This is where surprises — an unrecorded liability, an inconsistent add-back, a customer contract that doesn’t transfer — either get resolved quickly or blow up the deal entirely.
Financing and closing (variable, and this is the part that surprises people). If the buyer is paying cash, this can wrap in a couple of weeks. If they’re using SBA financing — and most individual buyers of businesses this size are — the standard SBA acquisition timeline runs 60-90 days from LOI to close, even after price and terms are agreed. That’s underwriting, SBA review, and closing conditions, stacked on top of diligence, not instead of it.
Add it up and a smooth deal on our hypothetical cleaning company runs 5-6 months from listing to wire transfer. A deal with financing hiccups, a diligence surprise, or a slow buyer search can stretch past 9.
Why Your Industry Changes the Number
The timeline isn’t the same for every business, and pretending otherwise leads owners to badly miscalibrate their expectations.
BizBuySell’s Q2 2026 data put the median time on market at 155 days for service businesses — the category most local cleaning, landscaping, and home-service companies fall into — versus 247 days for manufacturing.
The gap makes sense once you think about the buyer pool. Service businesses attract a wider range of buyers, including individual operators and first-time acquirers who can move relatively fast. Manufacturing deals draw a narrower, more specialized buyer pool, often involve real estate and equipment valuations that take longer to underwrite, and tend to need more financing structure to get done.
If you’re selling a service business, that’s good news on speed. It’s not a reason to skip the prep work — a faster average market doesn’t mean a fast sale for an unprepared seller.
What This Actually Means for When You Should Start
Here’s the part that trips owners up: the 5-8 month window starts once you’re actually ready to go to market, not from the day you decide you’d like to sell.
If your books need cleanup, if your add-backs need to be defensible instead of aggressive, if a chunk of your revenue lives with one customer relationship you personally hold — none of that gets fixed in a week. It gets fixed over months, ideally a year or more before you list.
An owner who wants to be out by next summer and starts prepping now is on a reasonable timeline. An owner who wants to be out by next summer and starts prepping in March is compressing four separate multi-week stages into a window that doesn’t fit them, and usually pays for it in valuation, terms, or both.
The Takeaway
Selling a business is not a 60-day process, and treating it like one is the fastest way to get frustrated with your broker, your buyer, or the market.
Plan on 5-8 months from a ready listing to a closed deal, longer if your industry, deal size, or buyer’s financing needs push it out. Build your prep timeline backward from your target exit date, not forward from the day you list.
The owners who get the best outcomes aren’t the ones who move fastest. They’re the ones who start early enough that the real timeline doesn’t catch them off guard.
If you’re thinking about an exit and curious what your business is worth — and what a realistic timeline looks like for your specific situation — that’s a conversation worth having well before you’re ready to list.
