How Long Does It Take to Sell a Business? A Realistic Timeline

I've handled 75+ transactions. The question I get more than almost any other is some version of this: "How long is this going to take?"

The honest answer is eight to nine months from engagement to wire, for a well-prepared business running a proper process. Some deals move faster. Some take longer. The variables that determine which category you land in are almost entirely within your control.

Here is what I have seen across hundreds of deal months, and what you need to know before you start.

The Full Timeline: What to Expect From Start to Close

Here is the realistic picture across 75+ deals:

| Phase | Typical Duration | |---|---| | Preparation (pre-market) | 1–3 months | | Going to market through first LOI | ~5 months | | LOI through close | 3–4 months | | Total (prep to wire) | 9–12 months |

The guarantee I make to every client: 40 serious buyers and an LOI in less than four months after going to market. That is the benchmark I hold myself to. The full timeline from wire to wire depends heavily on what you bring to the table at the start.

For a week-by-week interactive breakdown of the full deal process, I built the deal timeline tool at /deal-timeline. It is worth walking through before you engage an advisor so you know what each phase requires.

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

This phase happens before you formally engage an advisor or have any buyer conversations. Most founders skip it. That is a mistake.

What happens in preparation:

Financials are the foundation. Three years of reconciled income statements, tax returns, and bank statements. Every addback documented. SDE calculated clearly, with paper trails for every owner benefit and one-time expense. If your books are messy, this takes longer. But it is better to fix them now than to have a buyer's accountant find inconsistencies in diligence.

For larger deals (above $2M SDE), I recommend a pre-sale quality of earnings review from a third-party accounting firm. On a deal I managed in the supplement and ecommerce space, that QoE review prevented $300,000 in retrades during buyer negotiations. The buyer found an issue and came in with a price reduction demand. We handed them the third-party report. The conversation ended. The QoE paid for itself many times over.

Why this phase matters for timing: Sellers who go to market with clean, organized financials and documented processes move through buyer qualification, diligence, and close significantly faster than sellers who are reconstructing records on the fly. Every week you spend in preparation is weeks you save later when buyer attention is at its highest.

Phase 2: Going to Market and Finding Buyers (Months 1–3)

Once your financials and CIM are ready, the business goes to market. This is where process quality determines your timeline.

What happens in this phase:

The CIM (Confidential Information Memorandum) is completed and a teaser (a brief overview that does not name the business) is distributed to qualified buyers. Buyers who express interest sign an NDA before receiving the full CIM.

In my process, I reach 8,000+ direct buyer relationships and a 150,000-person buyer database. My average listing attracts around 97 buyers who sign NDAs. The volume of qualified buyer attention is what creates competition, and competition creates leverage.

During this phase, the seller's primary job is to be responsive. Buyer questions need answers within 24 hours. Preliminary meetings need to happen quickly. Momentum in this phase directly compresses the timeline to LOI.

What slows this phase down:

A weak teaser that fails to attract buyer interest. An unrealistic asking price that filters out serious buyers. A seller who is slow to respond to buyer inquiries. Each of these adds weeks, and in some cases months, to reaching a signed LOI.

Phase 3: LOI (Month 3–5)

The Letter of Intent is the buyer's written offer setting out the key terms: price, structure (cash at close vs. earnout vs. seller note), exclusivity period, and conditions.

The LOI phase is where I spend the most time in active negotiation on behalf of sellers. Multiple competing offers is the goal. Not just for price, but because it gives the seller real leverage on structure, timing, and terms.

A few things sellers need to understand about LOIs:

LOIs are typically non-binding on price but binding on exclusivity. Once you sign an LOI, you agree not to market the business to other buyers during the diligence period: usually 60 to 90 days. Choose the LOI you accept carefully.

The "best offer" is not always the highest headline number. Deal structure matters. A $5M all-cash LOI is often better than a $6M LOI with 40% in an earnout contingent on post-sale performance targets you may not control.

This is also where I set seller expectations on retrades. Nearly every deal I've managed has faced a price adjustment attempt after the LOI. On the $11.5M deal I managed, profits dipped seasonally after LOI signing. The buyer came in demanding a price reduction. My clients had multiple competing offers in reserve. I told the buyer they were prepared to walk and proceed with the next offer. The buyer backed down. "Whoever understands the deal structure best, and is willing to walk, controls the outcome." That principle requires multiple offers. Sellers who sign the only LOI they have cannot walk.

Phase 4: Due Diligence (Months 5–8)

Due diligence is the most time-variable phase of the entire process. For a well-prepared seller, it runs 45 to 90 days. For an unprepared seller, it can stretch to six months or kill the deal entirely.

What buyers are looking for in diligence:

Financial verification: the buyer's accountants are reconciling every financial statement against the underlying documentation. Bank statements, merchant processor reports, tax returns: all checked against the CIM financials. Any inconsistency triggers questions, and questions take time.

Legal review: contracts with customers, vendors, employees, and landlords. Any unresolved litigation. IP ownership documentation. The cleaner your legal file, the faster this moves.

Operational verification: the buyer is confirming that the business runs the way the CIM describes. Supplier relationships, customer concentration, team capabilities, documented processes: all reviewed in detail.

Technical diligence (for SaaS and software): codebase review, infrastructure documentation, third-party API dependencies, technical debt assessment.

The most important thing you can do in diligence:

Respond fast. Every day of delay in answering a buyer's diligence question is a day the deal stalls and external events have more time to reach in. The risk of external events killing a deal is real. I managed a deal in the ecommerce space that collapsed over a weekend. LOI signed. Financing approved. Lawyers aligned. The seller pushed for a retrade and delayed closing by one business day. Over that weekend, a tariff announcement spooked the lender. Financing pulled. Deal dead.

"Momentum protects deals. Time is risk. The longer a deal stays open, the more external risk it absorbs." Every unnecessary delay in diligence is a risk you are taking with your own outcome.

Phase 5: Purchase Agreement and Close (Months 7–9)

Once diligence is substantially complete and the buyer's financing is confirmed, lawyers move to drafting the purchase agreement. This phase typically runs four to six weeks.

What happens here:

The purchase agreement formalizes every deal term: final price, payment structure, representations and warranties, indemnification, transition obligations, non-compete, working capital target. This is where attorneys earn their fees.

Working capital is one of the most negotiated items at close that founders do not anticipate. Buyers want the business delivered with enough cash and current assets to operate day-to-day. How that target is calculated and what is included affects the net proceeds to the seller. Know this term before you get here.

Once the purchase agreement is signed, the closing mechanics are coordinated: wire transfer instructions, escrow accounts, entity documentation, final tax filings. When the wire hits, the deal is done.

"Never say a deal is done until the wire hits." I mean that literally. I have seen deals collapse in the final 48 hours. Stay disciplined and keep moving.

What Causes Deals to Take Longer

These are the most common timeline killers, in order of frequency:

1. Unprepared financials. Missing records, inconsistent revenue recognition, undocumented addbacks. Each gap requires reconstruction and explanation. That takes weeks, not days.

2. Owner dependency discovered in diligence. If buyers find that key client relationships or critical operational knowledge sits entirely with the founder, they slow down, reprice, or walk. This is a structural issue that takes months to fix and cannot be papered over in a CIM.

3. Client or customer concentration. A single client or customer above 25% to 30% of revenue creates lender concerns that slow or prevent financing approval. Lenders decide whether deals close, not just buyers.

4. Legal issues. Unresolved litigation, unclear IP ownership, contract disputes. Each one freezes a portion of diligence until resolved.

5. Retrade attempts. When buyers try to renegotiate after LOI, deals stall while both sides re-anchor expectations. The defense is multiple competing offers and a willingness to walk.

6. Seller fatigue. I've seen sellers who are so relieved to have an LOI that they become passive in diligence, slow to respond, and emotionally disengaged. The deal reads as fragile. Buyers and lenders sense it. The most dangerous emotion in an exit isn't fear. It's relief. "Relief replaced leverage without me even realizing it."

What Keeps Deals on Track

In my experience, deals that close on time share these characteristics:

Clean, pre-organized data rooms. The seller has every requested document ready before diligence begins. Buyers move faster when they are not waiting on records.

Responsive sellers. Twenty-four-hour turnarounds on diligence questions are the standard in well-run processes. Sellers who treat diligence response as urgent keep buyers engaged and prevent drift.

Realistic valuations from day one. Sellers who price correctly attract serious buyers. Serious buyers move faster and waste less time in negotiation theater.

Multiple competing offers. Competition compresses timelines because each buyer knows there is another buyer ready. No one drags their feet when they risk losing the deal.

An advisor who manages the timeline actively. This is not a passive process. I push buyers on diligence timelines, push lawyers on purchase agreement drafts, and push every party in the chain to move. Momentum is my job to protect.
