Timeline for Selling a Business: What to Expect

One of the most common surprises for first-time business sellers: how long the process actually takes. Most business owners assume they’ll list the business, find a buyer in a few weeks, and close in a couple of months. The reality is different — and understanding the real timeline helps you plan your exit without financial or personal stress.

The Realistic Timeline: 12–24 Months from Start to Close

For most businesses in the $1M–$20M revenue range, the full process from “I want to sell” to “the deal is closed” takes 12–24 months. Here’s how that breaks down.

Phase 1: Preparation (3–12 Months Before Going to Market)

This is the most important phase and the one most sellers skip or rush. Preparation includes: getting 2–3 years of clean, well-documented financials; building a Confidential Information Memorandum (CIM) that tells your business’s story; reducing owner dependency; identifying and addressing any legal, operational, or financial issues that would surface in due diligence; and working with an advisor to determine your valuation and target buyer profile.

Sellers who rush to market without preparation consistently get lower prices and more failed deals.

Phase 2: Going to Market and Finding a Buyer (3–9 Months)

Once you’re prepared, your advisor (broker or M&A advisor) will confidentially market the business to qualified buyers. This involves reaching out to strategic buyers, posting to business-for-sale marketplaces under a blind profile, and leveraging the advisor’s buyer network. Qualified buyers sign NDAs, receive the CIM, and begin their initial evaluation.

Receiving a serious offer typically takes 2–6 months from going to market. Some businesses sell in weeks; others take a year. The quality of the preparation and the advisor’s network are the biggest variables.

Phase 3: Letter of Intent and Exclusivity (2–4 Weeks)

When you find the right buyer at the right price, you sign a Letter of Intent (LOI). This is a non-binding agreement on the key deal terms — price, structure, earnout provisions, transition period, and exclusivity. During the exclusivity period (typically 30–90 days), you agree to negotiate only with that buyer while they complete due diligence.

Phase 4: Due Diligence (30–90 Days)

Due diligence is the buyer’s deep dive into everything about your business. Financial, legal, operational, customer, employee — nothing is off limits. This is where deals fall apart if the preparation wasn’t done. Expect to spend significant time answering questions, providing documents, and facilitating meetings between the buyer and your key employees and customers.

Phase 5: Negotiation, Closing Documents and Close (2–6 Weeks)

After due diligence, the purchase agreement is drafted and negotiated. This involves attorneys on both sides and can take 2–6 weeks. Once signed, funds are transferred, ownership changes, and you begin the transition period (typically 3–12 months of involvement to hand off relationships and knowledge).

The Bottom Line on Timing

If you want to be done in 18 months, start preparing now. The preparation phase is the variable you control. Everything after you go to market depends on market conditions, buyer availability, and deal complexity.
