The M&A Timeline: What Founders Should Expect

One of the most common questions we hear from founders considering a sale: "How long will this actually take?"

The honest answer: longer than you think, but there are ways to accelerate the process. This guide breaks down the typical M&A timeline and what happens at each stage.

The Short Answer

6-12
Months (Typical)
3-6
Months (Fast Track)
12-18
Months (Complex)

Most transactions take 6-12 months from initial engagement to close. However, this varies significantly based on preparation, deal complexity, and buyer type.

Phase 1: Preparation (4-12 Weeks)

Before going to market, you'll need to:

Financial Preparation

  • Compile 3-5 years of historical financials
  • Normalize for owner adjustments
  • Build a forward-looking financial model
  • Consider a sell-side Quality of Earnings

Legal Preparation

  • Clean up cap table issues
  • Review and organize key contracts
  • Address any known legal matters
  • Ensure IP assignments are complete

Operational Preparation

  • Document key processes
  • Identify key person dependencies
  • Prepare customer concentration analysis
  • Gather market and competitive data

Accelerator

The single biggest factor in timeline acceleration is preparation quality. A well-prepared data room can cut weeks off the process.

Phase 2: Marketing & Outreach (4-8 Weeks)

Confidential Information Memorandum

Your advisor will prepare a CIM that tells your story:

  • Executive summary and investment highlights
  • Company overview and history
  • Market analysis and competitive positioning
  • Financial performance and projections
  • Growth opportunities

Buyer Outreach

  • Develop target buyer list (strategic + financial)
  • Sign NDAs with qualified buyers
  • Distribute CIM and gauge interest
  • Schedule initial calls and meetings

The CIM is your first impression. Make sure it answers the questions buyers will ask and presents your company's story compellingly.

Phase 3: Management Presentations (3-6 Weeks)

Interested buyers will want to meet you and your team:

What to Expect

  • 2-3 hour in-person or video meetings
  • Deep dive into business model and financials
  • Q&A on strategy, team, and growth plans
  • Site visits for location-based businesses

How to Prepare

  • Practice your presentation multiple times
  • Anticipate tough questions
  • Prepare your management team
  • Have backup materials ready

Phase 4: Letter of Intent (2-4 Weeks)

What's in an LOI

  • Purchase price and structure
  • Key terms and conditions
  • Exclusivity period
  • Due diligence timeline
  • Expected closing date

Critical Decision Point

The LOI stage is where many founders make mistakes. Don't just focus on price — structure, terms, and buyer quality matter enormously.

Negotiating the LOI

Key terms to negotiate:

  • Earnout structures and triggers
  • Working capital targets
  • Rep & warranty insurance
  • Escrow and holdback amounts
  • Employment terms

Phase 5: Due Diligence (6-10 Weeks)

This is where most of your time goes:

Financial Due Diligence

  • Quality of Earnings analysis
  • Working capital normalization
  • Revenue quality review
  • Cost structure analysis

Legal Due Diligence

  • Contract review
  • IP verification
  • Employment matters
  • Regulatory compliance

Operational Due Diligence

  • Customer interviews (carefully managed)
  • Technology assessment
  • Facility reviews
  • Integration planning

Key Takeaway

Due diligence is where deals die. Thorough preparation and a well-organized data room dramatically reduce the risk of issues derailing your transaction.

Phase 6: Definitive Agreement & Close (4-8 Weeks)

Documentation

  • Purchase agreement negotiation
  • Disclosure schedules
  • Ancillary documents (employment, non-compete, transition services)
  • Third-party consents

Closing Conditions

  • Regulatory approvals (if needed)
  • Third-party consents
  • Financing confirmation
  • Rep & warranty insurance binding
