How Long Does It Take to Sell a Business?
The honest answer: longer than most sellers expect. A well-run process for a lower-middle-market business typically runs 9-12 months from launch to close — and that's before you factor in the 12-18 months of preparation that should happen first.
Key Takeaways
- ✓Total time from preparation to close is typically 18-30 months
- ✓The sale process itself (launch to close) averages 6-12 months
- ✓Due diligence and legal documentation are the most common delay points
- ✓Preparation quality directly affects process speed — clean deals close faster

1The two phases people confuse
There's a difference between sale preparation and the sale process itself. Most sellers conflate them — which is why they consistently underestimate the total timeline.
Preparation (12-18 months): Getting financials clean, fixing operational gaps, reducing key-person dependency.
Sale process (6-12 months): Active marketing to buyers, managing NDAs, distributing the CIM, running management meetings, negotiating LOIs, and closing.
Add those together: 18-30 months from decision to cash in hand. That's realistic for most lower-middle-market deals. The sellers who close fastest are the ones who started preparing long before they thought they were ready.
2Stage-by-stage process timeline
Weeks 1-4: Process launch. Advisor engaged, CIM and financial model prepared, target buyer list finalized, teasers distributed.
Weeks 4-8: First round. NDAs signed, CIM distributed to qualified buyers, initial indications of interest collected.
Weeks 8-14: Management meetings. Serious buyers meet with management. Second-round bids submitted. LOI negotiated and signed.
Weeks 14-24: Due diligence. Buyer conducts full financial, legal, and operational diligence. This phase is the most variable — clean deals can move in 6-8 weeks; messy ones drag 4-6 months.
Weeks 24-30: Legal and close. Purchase agreement negotiated, financing confirmed, final conditions satisfied, transaction closes.
The LOI-to-close phase is where most deals fall apart or get repriced. Having your diligence materials organized before the process launches significantly reduces surprises at this stage.
3What causes deals to take longer
Diligence surprises. Issues that surface in due diligence — undisclosed liabilities, financial restatements, customer concentration — slow everything down and often result in price renegotiation.
Financing delays. If the buyer is using SBA or bank financing, the lender timeline adds 60-90 days minimum.
Seller hesitation. Some sellers get cold feet mid-process. This creates uncertainty, sometimes costing the deal entirely.
Legal complexity. Multi-entity structures, earnout negotiations, rep and warranty insurance — each adds time.
Start the Readiness Assessment Early
The earlier you assess client readiness, the more time you have to address gaps before launching a process.
