A sell-side M&A process moves through a predictable sequence, even though the pace and outcome of each step vary by deal. Broadly: preparation, building marketing materials, confidential buyer outreach, screening indications of interest, management meetings, negotiating a letter of intent, due diligence, drafting a definitive agreement, and closing. Knowing what happens at each stage — and what is expected of you as the owner — lets you make faster, calmer decisions when you are actually in the middle of it rather than learning the process for the first time under time pressure.
1. Preparation
Before any buyer sees your business, preparation establishes the foundation for everything that follows. This typically includes normalizing three years of financial statements, documenting add-backs, resolving obvious legal or contract gaps, and clarifying how the business would run without you day to day. It also includes internal alignment — if there are multiple family shareholders, agreeing on price expectations, deal structure preferences, and roles going forward before a buyer is in the picture, not during negotiation.
This is also when you engage an advisor, sign an engagement letter, and agree on objectives, process and confidentiality protocols. Preparation quality is the single largest lever on both how fast the rest of the process moves and how much negotiating leverage you keep once buyers are engaged.
2. Building marketing materials
Two documents typically anchor buyer outreach: a teaser, a one- or two-page anonymized summary highlighting the opportunity without revealing your company's identity, and a confidential information memorandum (CIM), a detailed document covering financial performance, operations, market position, and growth opportunity, shared only after a buyer signs a non-disclosure agreement. A well-built CIM answers the questions a serious buyer will ask before they ask them, which shortens the screening phase that follows.
3. Confidential buyer outreach
Your advisor develops a buyer list — typically a mix of strategic acquirers, private equity firms, and, where relevant, family offices or international buyers — and reaches out under strict confidentiality. Interested parties sign a non-disclosure agreement before receiving the CIM. Maintaining confidentiality at this stage matters for reasons beyond comfort: employees, customers, and competitors learning prematurely that a business is for sale can itself affect the business's value and stability during the process.
4. Indications of interest (IOIs)
Buyers who review the CIM and remain interested typically submit a non-binding indication of interest — a preliminary letter outlining a proposed valuation range, structure, and key assumptions. IOIs let you screen for serious, well-resourced buyers before investing more time, and they give an early read on where the market is likely to land on valuation. Not every recipient of a CIM submits an IOI, and that is a normal part of narrowing the field.
5. Management meetings
Buyers who submitted a credible IOI typically move to management meetings — in-person or virtual sessions where your leadership team presents the business in more depth and buyers ask direct questions about operations, customers, and growth plans. This is often the point at which a buyer's enthusiasm (or hesitation) becomes clear, and it is also where owners get their first real read on cultural fit, which matters more than many sellers initially expect, particularly for family-owned businesses considering how a transition will affect employees and legacy.
6. Letter of intent (LOI)
After management meetings, one or more buyers submit a letter of intent — a more detailed, though still largely non-binding, document setting out proposed price, structure, exclusivity period, and key terms. Signing an LOI typically grants the buyer a period of exclusivity to complete due diligence, which is why choosing the right buyer at this stage — not just the highest headline number — matters: an LOI takes your business off the market for the buyer you selected, so terms like deal structure, financing contingency, and the buyer's track record of closing deals deserve as much scrutiny as price.
7. Due diligence
Due diligence is the most intensive phase of the process, typically running several months. The buyer's team — often including accountants, lawyers, and industry consultants — reviews financial records, contracts, legal matters, operations, and commercial relationships in detail. This is where the preparation from Step 1 pays off directly: well-organized records and previously disclosed issues move through review quickly, while surprises discovered during diligence routinely lead to price adjustments or, in the more difficult cases, a buyer walking away.
8. Definitive agreement
Once due diligence is substantially complete, the parties negotiate the definitive purchase agreement — the binding legal contract governing the transaction, including final price, representations and warranties, indemnification terms, and closing conditions. This is typically the most legally intensive stage and benefits from experienced M&A counsel working alongside your advisor, since the definitive agreement is what actually governs your post-closing obligations and risk.
9. Closing
At closing, signatures are exchanged, funds are transferred, and ownership formally passes to the buyer. Depending on deal structure, some portion of proceeds may be held in escrow against future claims, or tied to an earn-out based on post-closing performance. Closing is a milestone, not necessarily the end of your involvement — many transactions include a transition period.
10. Transition
Most sell-side deals include some form of post-closing transition — a period, often three to twelve months, during which the seller (or key managers) support a smooth handover of relationships, knowledge, and operations. Transition terms are typically negotiated as part of the LOI and formalized in the definitive agreement, and how well this period is planned in advance often shapes how the deal is remembered by employees and customers, even after the legal process is complete.

Why sequence matters
Skipping or rushing an early step usually costs more time later. A CIM built without proper financial normalization tends to generate more buyer questions during diligence, not fewer. An LOI signed without clarity on deal structure tends to reopen negotiation mid-diligence. Treating each stage as a genuine gate — not a formality to move past quickly — is what keeps a sell-side process on a realistic timeline.

The Confluence™ work is built around managing exactly this sequence on a seller's behalf — from buyer identification through closing — while The Goldsmith™ addresses Step 1 before you ever go to market. The specific pace and emphasis of each stage can vary by industry; see the sectors we serve for context on how this plays out across fintech and blockchain, food and agriculture, and other markets.
Frequently asked questions
What is the difference between an IOI and an LOI?
An indication of interest (IOI) is an early, non-binding signal of interest with a preliminary valuation range, typically submitted before management meetings. A letter of intent (LOI) comes later, after buyers have more information, and typically includes more detailed terms plus an exclusivity period during which the buyer completes due diligence.
Do I need to disclose that my business is for sale to employees during this process?
Confidentiality is maintained deliberately through most of the process specifically to avoid this. Buyers sign non-disclosure agreements before receiving detailed information, and most owners choose to inform employees only once a deal is signed or very close to closing, to protect stability during the process itself.
Can a deal fall apart after the letter of intent is signed?
Yes. An LOI is typically non-binding on price and most terms, and due diligence sometimes surfaces issues that lead a buyer to renegotiate or withdraw. This is one reason preparation before going to market matters: it reduces the odds of late-stage surprises.
How involved do I need to be in due diligence?
Meaningfully involved. Due diligence requires timely access to financial records, contracts, and staff who can answer buyer questions, and delays in providing information are one of the most common causes of a due diligence phase running longer than expected.
