A sell-side M&A advisor manages the entire process of selling your company. That sentence is technically correct and completely useless. What does “manage the process” actually mean? According to Axial’s 2025 research, business owners who self-represent spend an extra 25 to 30 hours per week managing their exit on top of running the business. The advisor absorbs that workload. Here is exactly what that looks like, week by week, from engagement letter to closing wire.
I have run this process hundreds of times. The timeline below reflects a typical lower middle market SaaS transaction. Your deal will vary, but the phases and deliverables stay consistent.
Weeks 1-4: Preparation and Valuation
The work that happens before any buyer knows you exist.
This is where the advisor earns the retainer. Most founders underestimate how much preparation goes into a successful exit.
- Week 1: Deep dive and data gathering — The advisor collects three years of financials, customer data, contracts, organizational charts, and product documentation. This is an intensive information request. Expect 50 to 100 items on the list.
- Week 2: Financial normalization and valuation — The advisor builds an adjusted EBITDA or ARR analysis, normalizing for owner compensation, one-time expenses, and non-recurring revenue. This becomes the basis for your valuation range.
- Week 3: Positioning strategy — What is the story? Not marketing spin. The genuine investment thesis: why this company, why now, why the growth trajectory is defensible. The advisor identifies which buyer types will pay the most and tailors the pitch accordingly.
- Week 4: CIM drafting — The Confidential Information Memorandum is your company’s pitch book. It covers financials, operations, market opportunity, growth levers, and team. A strong CIM runs 30 to 50 pages. Learn more about how a CIM is built.
That is how much time self-represented owners spend managing their own exit process, according to Axial research. An advisor absorbs this so you can keep running the business.
Weeks 5-8: Buyer Outreach and Initial Interest
The advisor builds a buyer universe. This is not sending your CIM to a mailing list. It is a targeted, confidential outreach to 50 to 200 qualified buyers.
- Week 5: Buyer list development — The advisor identifies strategic acquirers, private equity firms, family offices, and search funds with a thesis that matches your company. At Livmo, we use platforms like Axial alongside proprietary relationships. The buyer list is reviewed with you. You have veto power over who sees your information.
- Week 6: Teaser distribution and NDA management — A one-page anonymous teaser goes out. Interested buyers sign NDAs. The advisor manages this entire flow. In a typical process, 30 to 60% of contacted buyers request the NDA.
- Weeks 7-8: CIM distribution and Q&A — Qualified, NDA-signed buyers receive the CIM. The advisor fields questions, schedules calls, and manages information flow. This is where the funnel narrows. Out of 100 outreaches, 30 sign NDAs, 15 review the CIM, and 5 to 8 express serious interest. Expect a two-week review window per Capstone Partners’ process guide.
The advisor’s job during outreach is creating competitive tension. Multiple interested buyers means leverage. A single buyer means their terms.
Weeks 9-14: Indications of Interest and LOI
This is where the deal starts to feel real.
Serious buyers submit Indications of Interest (IOIs). These are non-binding offers that outline valuation range, deal structure, and key terms.
- Weeks 9-10: IOI collection and analysis — The advisor collects IOIs and builds a comparison matrix. Price is not everything. Structure matters: cash at close vs. earnouts, rollover equity, working capital assumptions, transition requirements. The advisor helps you compare apples to apples.
- Weeks 11-12: Management presentations — You meet the top 2 to 4 buyers. The advisor prepares you, coaches on tough questions, and sits in every meeting. This is where buyers evaluate you as much as the business.
- Weeks 13-14: LOI negotiation — The advisor negotiates the Letter of Intent with the preferred buyer. Key terms include purchase price, exclusivity period, working capital targets, and deal structure. This stage typically takes 4 to 6 weeks from first management presentation to signed LOI, per Sampford Advisors.
Weeks 15-22: Due Diligence and Closing
You have a signed LOI. Now the buyer’s team examines everything. This is where deals die or get repriced if you are unprepared. Read our guide on due diligence red flags that kill deals.
- Weeks 15-18: Due diligence management — The buyer’s team (legal, financial, technical) submits hundreds of requests. The advisor manages the data room, tracks responses, and shields you from unnecessary distraction. A typical SaaS due diligence process involves 200 to 500 document requests.
- Weeks 19-20: Purchase agreement negotiation — Lawyers draft the definitive agreement. The advisor negotiates business terms: representations and warranties, indemnification caps, escrow amounts, and working capital adjustments. This is where detailed, experienced guidance saves real money.
- Weeks 21-22: Closing mechanics — Final approvals, funds flow, signing. The advisor coordinates between legal, financial, and operational teams to get to the wire transfer. For a complete guide on this phase, see our LOI to closing guide.
The full sell-side M&A process typically takes 6 to 9 months from engagement to close. Auxo Capital Advisors and other middle market firms cite 9 to 12 months for complex transactions. For more detail on each phase, explore the M&A Process Roadmap on our learning hub.
What the Advisor Does That You Cannot See
The timeline above covers the visible work. The invisible work is equally important.
- Emotional buffer — Selling your company is one of the most stressful financial decisions you will make. The advisor absorbs buyer frustrations, pushback on price, and late-night demands so you do not have to.
- Deal preservation — When issues arise (and they always do), the advisor finds creative solutions. A working capital dispute. A last-minute rep and warranty request. A competing offer. The advisor’s job is to keep the deal moving.
- Market intelligence — The advisor knows what similar companies sold for last quarter. What terms buyers are offering in your sector. Which PE firms are actively deploying capital. You cannot negotiate effectively without this context.
An M&A advisor’s value compounds at each phase. The CIM quality drives buyer interest. Buyer competition drives price. Deal management protects that price through closing.
Frequently Asked Questions
What does an M&A advisor do?
An M&A advisor manages the entire sale process: valuation, CIM creation, buyer identification and outreach, offer negotiation, due diligence management, and closing coordination. The typical engagement runs 6 to 9 months for a lower middle market transaction.
Is an M&A advisor worth the fee?
For most lower middle market transactions, yes. Advisors create competitive tension among buyers that typically results in higher valuations than direct negotiations. They also prevent value leakage during due diligence and closing. The success fee (typically 3-6% of transaction value) is usually offset by the valuation premium the advisor creates. Read more about why advisors charge retainers.
How long does the M&A process take?
A typical lower middle market sell-side process takes 6 to 9 months from engagement to close. Complex transactions or those requiring significant preparation can take 9 to 12 months. The preparation phase (weeks 1-4) and due diligence (weeks 15-22) are the phases most likely to extend.
What is the difference between an M&A advisor and a business broker?
M&A advisors typically handle larger, more complex transactions (usually above $1M in enterprise value) with a structured, competitive process. Business brokers often work with smaller deals and may list businesses more passively. See our detailed comparison of M&A advisors vs. brokers vs. intermediaries.
What should I look for when hiring an M&A advisor?
Look for relevant transaction experience in your industry and deal size range, a clear process they can walk you through, references from past clients, and alignment on timeline and expectations. Avoid advisors who guarantee a sale price or who cannot explain their buyer outreach strategy in detail.
