How Long Does It Take to Sell a Business?

The five phases of a business sale and their typical duration

Here is how the timeline breaks down for a typical SMB transaction:

Phase 1: Preparation (2–8 weeks)

Organizing financials, preparing the CIM, getting legal documents in order, and identifying the buyer channel. If your books are clean and organized, this is two to four weeks. If your accountant needs to reconstruct three years of P&Ls, it's eight or more.

Phase 2: Buyer outreach and qualification (4–12 weeks)

Marketing the business (confidentially or through a broker), receiving inquiries, screening buyers, signing NDAs, sharing information packages, and holding introductory calls. The range here is wide — a broker with a strong buyer database may compress this; a solo seller without a clear buyer channel may spend months in this phase.

Phase 3: LOI to due diligence (2–6 weeks after receiving LOI)

Once you receive a letter of intent, negotiating its terms typically takes one to two weeks. Moving into due diligence begins immediately after signing. The LOI stage can also include multiple rounds of IOIs and a selection process if you're running a competitive process.

Phase 4: Due diligence (30–90 days)

The buyer's team reviews financial records, legal documents, operations, customer data, and anything else material to the transaction. For clean, well-prepared businesses with organized data rooms: 30–45 days. For businesses with disorganized records, multiple entities, or complex operations: 60–90 days.

Phase 5: Purchase agreement and closing (2–6 weeks after due diligence)

Negotiating and drafting the purchase agreement, resolving open items, coordinating financing (if SBA or bank financing is involved), and closing. SBA loans in particular add time — lender approval and appraisal can extend this phase by four to six weeks.

Total: 4–18 months from first buyer contact to close.

Why some deals take much longer

The most common reasons sales extend well beyond the expected timeline:

Disorganized financials. If your P&Ls don't reconcile to your tax returns, buyers will stop and wait for clean numbers. Every week your accountant spends reconstructing records is a week the deal sits still.

Owner dependency discovered in due diligence. Buyers who realize mid-due-diligence that the business cannot function without the owner often restructure the deal — lower upfront, more earnout — or walk away. Renegotiating deal structure after LOI is time-consuming.

Customer or contract concentration. If 40% of revenue is from one customer, buyers may insist on a condition: a new multi-year contract with that customer before close. Getting a customer to sign a new long-term agreement is a separate negotiation that can take months.

SBA or bank financing delays. If the buyer is using SBA 7(a) financing, the lender's process — appraisal, approval, documentation — adds 60–90 days on its own. SBA deals take longer than all-cash or PE deals.

Lease assignment. If the business is tied to a physical location, the landlord must approve the assignment of the lease to the new owner. Landlords who use this as an opportunity to renegotiate terms can stall a deal for weeks.

Multiple stakeholders. Deals with multiple sellers (partnership situations), earnouts that require complex modeling, or equity rollovers introduce coordination overhead that extends timeline.

How buyer type affects speed

Different buyer types have very different process speeds:

PE-backed strategic buyers: Fastest. PE platforms that do multiple deals per year have established processes, deal teams, and legal templates. A PE buyer who has done their preliminary diligence on your industry can move from LOI to close in 60–90 days if you're organized.

Individual strategic buyers (owner-operators expanding): Moderate speed. Experienced operators who have bought businesses before know the process. First-time buyers move more slowly because they're learning the process at the same time.

Search funds: Moderate to fast. Searchers are motivated to close because their fund has a limited life. They typically have legal and financial advisors already selected. Good process, but lender involvement if they're using SBA financing adds time.

Individual owner-operators (first acquisition): Slowest. First-time buyers move more cautiously, often with less support from experienced advisors. They may pause at every unfamiliar step. This isn't a reason to avoid them — some are excellent buyers — but set realistic timeline expectations.

Family succession: Highly variable. Can be fast (if the family member is ready and financing is arranged) or can take years (if it's conditional on performance milestones or financing approval).

The most important factor: how prepared you are at day one

Everything above assumes you begin the process organized. The single biggest driver of deal timeline is whether you have your information ready when buyers ask for it.

A buyer asking for three years of financial statements who receives them the same day they ask will continue moving forward. A seller who says "let me get back to you on that" and takes two weeks to compile the records has introduced friction and uncertainty into the buyer's process.

What should be ready before you contact the first buyer:

• Three years of P&Ls, reviewed and reconciled
• Three years of tax returns filed
• Customer revenue list (top 20 by revenue, trailing 12 months)
• Employee roster with roles and tenure
• Current copy of all material contracts (leases, supplier agreements, top customer agreements)
• Asset list with values

If any of these require significant assembly, complete that work before buyer outreach begins. The time you spend preparing before the process is time you save in the process.

When deals fall apart (and what it means for timing)

Roughly 30–40% of business deals that reach LOI do not close. Understanding why helps you avoid the situations that lead to re-do:

Discovery of undisclosed issues: Something a buyer finds in due diligence that wasn't represented accurately — or simply wasn't disclosed. Even if not intentional, these discoveries create renegotiation or deal failure.

Buyer financing falling through: SBA loans get declined. Bank financing gets pulled in rate environment changes. All-cash buyers who turn out to need financing that they haven't secured.

Seller changing their mind: Sellers who weren't committed to selling in the first place sometimes withdraw mid-process when the reality of the transition becomes concrete.

Price expectation disconnect: The seller's mental value and the market's actual value are misaligned. This is most common when sellers price based on what they need for retirement rather than what the business's financials support.

If your deal falls apart: You're not starting over from zero. Most of the preparation work, the CIM, the financial documentation, is still valid for the next buyer process. What you've lost is time and some confidentiality. Most sellers who experience a failed deal and restart the process close successfully within 6–12 months.

What you can do to compress the timeline

If you need to sell within a specific window, here are the levers that actually help:

Prioritize organized buyers. PE platforms and search funds with established processes move faster than first-time buyers. Targeting your process toward organized, experienced acquirers reduces the time lost to process uncertainty.

Prepare a complete data room before outreach. Having all due diligence materials ready before a buyer asks is the single biggest time-saver in the process.

Set a target LOI deadline in your outreach. When inviting buyers to submit offers, giving a soft deadline ("we are inviting offers by [date]") creates urgency without being coercive. Buyers who are interested will prioritize your process.

Use a private matching platform to reduce buyer search time. Rather than spending 8–12 weeks in buyer outreach, a platform that matches your profile to active buyer mandates can compress the qualified-buyer-identification phase to 2–4 weeks.

Pre-negotiate with your landlord. If your lease assignment will require landlord approval, have that conversation early — before LOI, not after. A cooperative landlord doesn't slow down closing.
