A Letter of Intent is more than a preliminary agreement. It sets the foundation for the entire acquisition process. Before signing, buyers should assess financial performance, operational risks, legal obligations, customer concentration, management dependency, and growth assumptions. Thorough buy-side due diligence uncovers risks that financial statements alone cannot reveal.
What Is a Letter of Intent in a Business Acquisition?
A Letter of Intent (LOI) outlines the key commercial terms of a proposed acquisition before the definitive purchase agreement is drafted. While many provisions are non-binding, clauses such as exclusivity, confidentiality, and governing law are often legally enforceable.
For buyers, signing an LOI typically initiates formal due diligence. It also commits time, advisory costs, and resources. Entering this stage without preparation can weaken your negotiating position if significant issues emerge later. An LOI should be based on informed assumptions, not optimistic expectations.
Why Is Buy-Side Due Diligence So Important Before Signing?
Many acquisitions fail to deliver expected value because buyers discover operational, financial, or commercial issues after signing. Buy-side due diligence answers one critical question: is this business worth buying at the agreed valuation?
More importantly, it identifies risks that may justify renegotiating the purchase price, changing deal terms, requesting seller warranties or indemnities, structuring an earn-out, or walking away entirely. Our transaction advisory team runs this work alongside buyers and investors.
What Doesn't Financial Data Tell You?
Financial statements explain what has happened historically. They rarely explain why it happened or whether those results are sustainable.
| Financial Reports Show | Due Diligence Reveals |
|---|---|
| Revenue growth | Whether growth is sustainable |
| Profit margins | Hidden operational inefficiencies |
| EBITDA | Quality and recurring nature of earnings |
| Cash balance | Actual working capital requirements |
| Customer revenue | Customer concentration risk |
| Expenses | One-off or unusual costs |
| Assets | Condition, ownership, and maintenance needs |
| Historical performance | Future scalability and operational capacity |
What Are the Biggest Risks Buyers Overlook?
Customer concentration
If a significant percentage of revenue depends on one or two customers, losing them after acquisition can materially reduce value. Ask what percentage of revenue comes from the top five customers, whether contracts are long-term or informal, and what retention history looks like.
Owner dependency
Many businesses rely heavily on the founder for sales, operations, supplier relationships, or decision making. Can the business operate without the owner? Are key processes documented? Is there a capable management team? If not, transition risk increases substantially.
Working capital requirements
Businesses may appear profitable while requiring significant cash to operate. Understand seasonal fluctuations, inventory requirements, receivable quality, and supplier payment obligations, because they directly determine how much capital is needed after closing.
Quality of earnings
Reported EBITDA may include personal expenses, one-time revenue, temporary cost reductions, non-recurring support, or aggressive accounting adjustments. A Quality of Earnings analysis determines true sustainable earnings. The same discipline applies on the sell side, as covered in our guide to preparing for a private equity exit.
Operational inefficiencies
Review technology infrastructure, ERP systems, cybersecurity, internal controls, inventory management, reporting processes, staff capability, and compliance procedures. Operational improvements often create more acquisition value than cost cutting alone, and system weaknesses are a frequent post-close surprise.
What Should Buyers Review Before Signing an LOI?
| Area | Questions to Ask |
|---|---|
| Financial | Are earnings sustainable? |
| Tax | Are there outstanding liabilities? |
| Legal | Are contracts enforceable? |
| Commercial | Is market demand growing? |
| Operations | Can the business scale efficiently? |
| Human Resources | Are key employees likely to stay? |
| Technology | Are systems secure and modern? |
| Compliance | Are there regulatory risks? |
| Supply Chain | Are suppliers diversified? |
| Customers | Is revenue recurring and diversified? |

How Does Due Diligence Influence Deal Structure?
Due diligence does more than identify problems. Findings shape purchase price adjustments, earn-out structures, holdbacks or escrow arrangements, working capital targets, seller warranties, indemnification clauses, financing strategy, and post-acquisition integration planning. Strong diligence provides objective evidence for negotiating better terms rather than relying on assumptions.
Integration planning should start before closing. Our guide to the 90-day cliff after an acquisition covers how quickly value can erode without it.
Expert Insight: The Most Valuable Findings Are Often Non-Financial
Experienced transaction advisors frequently identify greater risks in operational processes, customer relationships, leadership dependency, technology, and governance than in the financial statements themselves. Businesses with clean records can still become difficult acquisitions if they rely on undocumented processes, outdated systems, or a founder whose knowledge has never been transferred.

Frequently Asked Questions
What is the purpose of a Letter of Intent?
A Letter of Intent establishes the proposed commercial terms of an acquisition and provides a framework for conducting detailed due diligence before entering a definitive purchase agreement. Certain provisions, such as confidentiality and exclusivity, may be legally binding.
Is an LOI legally binding?
Most commercial terms are non-binding. However, clauses relating to confidentiality, exclusivity, governing law, and expenses are often enforceable. Buyers should obtain legal advice before signing.
Why is buy-side due diligence important?
It validates financial information, identifies operational and commercial risks, confirms valuation assumptions, and helps buyers negotiate stronger terms while reducing acquisition risk.
What is a Quality of Earnings report?
A Quality of Earnings report evaluates whether reported profits accurately reflect sustainable business performance. It identifies unusual, non-recurring, or adjusted items that may affect valuation.
Can due diligence reduce the purchase price?
Yes. Material findings such as customer concentration, declining margins, tax liabilities, or operational weaknesses often support price adjustments or changes to transaction structure.
When should due diligence begin?
Initial commercial, financial, and strategic assessments should begin before signing the LOI. Detailed diligence typically accelerates immediately after execution during the exclusivity period.
Should smaller acquisitions still involve due diligence?
Absolutely. Smaller businesses often have greater owner dependency, weaker internal controls, and limited documentation, making comprehensive due diligence even more valuable.
How can professional advisors help buyers?
Transaction advisors coordinate financial, operational, tax, legal, and commercial reviews, helping buyers identify risks early, validate valuation assumptions, and negotiate terms that protect long-term value.
