Vendor Due Diligence (VDD) includes, but is not limited to, a comprehensive in depth analysis of financial, commercial, operational and in some instances legal reviews conducted by the shareholders of the selling party (“seller”) before entering M&A discussions with a potential acquirer or group of acquirers. VDD is usually initiated by the seller to proactively assess and disclose key business risks, financial performance, and/or operational insights.

Unlike buy-side due diligence – where the acquirer performs its own investigation after entering discussions with the seller – the VDD process typically involves third-party advisors (usually separate for each aspect of financial, commercial, operational and legal) conducting an independent evaluation, resulting in a Vendor Due Diligence Report. This VDD report provides potential buyers with a transparent and credible overview of the business supported by an independent third party, which helps streamline negotiations, reduces the time of the transactions and limits potential impacts of identified risks on the transaction value.

1. Smoother and faster M&A transactions
   VDD helps identify and resolve potential issues before buyers have a chance to look at the business in detail which helps the seller to identify and address risks and concerns, which in turn reduces delays and unknown last-minute surprises in the deal process.
2. VDD reports increases confidence
   A well-prepared vendor due diligence report enhances credibility, demonstrating transparency and reducing buyer concerns. The report provides a view from a buyer perspective, which is particularly valuable in competitive sale processes where multiple bidders are involved.
3. A stronger position for the seller
   Sellers control the narrative by addressing financial or operational weaknesses upfront, which minimises the risk for negative negotiations in comparison to buyer-led investigations.
4. Can lead to a reduction in disruption to day-to-day business operations
   A single, well-prepared vendor due diligence report addresses a lot of buyer questions that minimises disruption, allowing management to focus on running the business.
5. The VDD process helps to identify and mitigate risks in advance
   Issues that are identified can be corrected before entering negotiations. This increases the confidence of buyers and reduces the time during the negotiations. Some common risks that are common to Small and Medium Enterprises (SME):

6. Preparation is key
   Seller prepared due diligence provides assurance to buyers that the business as well as management have been well-prepared, allowing the focus to be on what matters.

Both vendor due diligence (VDD) and buy-side due diligence are critical in M&A transactions, but they serve different purposes and are conducted by different parties during the course of the transaction.

Vendor Due Diligence (VDD) is initiated and conducted by the seller (with external advisors) and the main purpose as mentioned above is to prepare the business for sale, identify risks, mitigate those risks and finally, to provide buyers with a structured, transparent report validated by a third party.

Buy-side Due Diligence is initiated by the buyer (usually with external advisors) with the main purpose being to assess the business from a financial, legal and commercial perspective. This includes identification of risks and potential opportunities to ensure the business is in alignment with the buyer’s strategic objectives.

Here are the key differences:

Vendor Due Diligence provides a structured, seller-led review to give buyers confidence, while Buy-Side Due Diligence is a buyer-driven, risk-focused investigation. Both are crucial in M&A, but for sellers, VDD can speed up transactions, reduce deal risk, and improve valuation outcomes.

A structured vendor due diligence (VDD) process helps sellers as well as advisors prepare for the M&A transaction. The process helps to identify and mitigate risks, allowing for a better narrative during the information memorandum stage whilst ensuring transparency to buyers. This naturally helps to accelerate deal timelines. Whether Buy-side Due Diligence or Seller Due Diligence (VDD), the process would generally follow the same pattern.

Key Steps in the Due Diligence Process:

1. Preparation – The seller gathers financial, legal, and operational documents in accordance with the scope of the selected service.
2. Financial Due Diligence – This entails a deep dive into the earnings of the business, cash flow, debt, working capital and key assets within the business, whilst also identifying trends that are key to the running of the business.
3. Legal & Compliance Review – Assessment of statutory legal documents, contracts, liabilities, regulatory obligations, and intellectual property.
4. Operational & Market Assessment – Evaluating supply chain strength, customer concentration and analysis, as well as competitive positioning.
5. Risk Identification & Mitigation – Addressing red flags identified during the detailed workstream for example financial inconsistencies, legal disputes, or customer dependencies.
6. Report & Buyer Access – Findings are compiled into a Vendor Due Diligence Report, which is shared with potential buyers. Once reviewed and following a questions and answers session with the third party advisor, the option for the buyer to place reliance on the report is given through a letter of reliance from the due diligence provider.

By proactively conducting vendor due diligence, sellers place themselves in the stronger position during the negotiation of a transaction and managing the timeliness of the transaction.

• Financial Records: Ensure audited financial statements, management accounts, and tax filings are up to date. The preference for most M&A transactions are monthly available management accounts which include a Profit and Loss, Balance Sheet and Cash Flow statement. If this is not available, your advisor should be able to assist you with the best way forward.
• Legal Documentation: Gathering or categorisation of contracts (this includes for example, employees, key customers or clients, key suppliers and any hire purchase contracts), intellectual property (IP) records, property documentation and shareholder agreements etc.
• Operational Data: This includes documentation and policies which is in alignment of governance within the sector in which the business operates, risk management, compliance frameworks etc.
• Vendor Due Diligence Checklist: For each VDD workstream, you will be provided with an Information Request List (IRL) which enables you to systematically work through the requirements and answer the questions that relate to the due diligence undertaken. This provides the 3rd party

By addressing gaps early, sellers can proactively manage risks and avoid delays during buyer scrutiny.

In general terms, buyers tend to focus more heavily on financial due diligence to assess profitability and cash flow sustainability. The financial due diligence report is usually a requirement for funding purposes and also provides clarity and certainty to the buyer that they are buying a business underpinned by a certain level of financial performance. Within the narrative of the financial due diligence, focus is particularly given to:

• Quality of Earnings (QoE): Identify one-off, non-recurring revenues or expenses that could distort sustainable profits. A buyer wants to know what the normal course of business profits are.
• Cash Flow Analysis: By assessing working capital trends and cycles, the cash flow sustainability, and debt obligations, a buyer can determine how much of the profits are convertible to cash and what the cash requirements together with the working capital requirements are.
• Revenue & Margin Trends: Depending on the type of business, these trends provide clear insights into customer concentration, pricing models, the nature of revenue (whether it is recurring or not) and the seasonality of the business.
• Debt & Liabilities: The buyer as well as the funding party (if any) will be interested in clarifying what the outstanding debt, contingent liabilities, and potential off-balance-sheet items are to which it will become the owner of. Debt is usually paid off as part of the consideration offered, however some items will naturally be transferred to the new owners where liabilities are key to the business operation.

From a seller point of view, a robust vendor financial due diligence report ensures financial clarity, reducing the risk of price renegotiations during the transaction.

Vendor Legal Due Diligence usually forms part of the Legal scope of the transaction process and is usually performed by the legal advisor selected by the seller. This VDD helps identify contractual risks, regulatory exposures and any shortcomings within the requirements of a share sale or divestment of assets. The focus of Legal Due Diligence is mainly driven by:

• Key Contracts: Review of supplier agreements (including property, IP and various other key contracts), customer contracts, and employment terms.
• Litigation & Disputes: This review helps to identify and disclose any ongoing or past legal claims that may impact valuation.
• Regulatory Compliance: Ensures the business meets industry-specific laws, including GDPR, ESG, and employment regulations.
• Intellectual Property (IP): Verify trademarks, patents, and licenses are correctly documented.

Addressing legal gaps proactively addresses the risks which a buyer might be on the lookout for and also helps to drive the legal documentation to mitigate risks after the transaction has been completed.

Beyond financials and legal risks, buyers assess a company’s market position, customer base, and operational resilience. This is usually referred to as Commercial Due Diligence (CDD) and although there are 3rd parties that provide this service, it is in some deals done internally by the buyer’s M&A team. CDD is usually undertaken where a buyer is entering a new market segment or industry. Key focus areas of CDD includes:

• Customer Base Analysis: Evaluate customer retention rates, revenue concentration, and churn risk. This could also at times include customer or client surveys which provides a perspective on client satisfaction and likelihood of retention.
• Supply Chain Resilience: Assess supplier dependencies and potential vulnerabilities. Buyers could use this assessment to determine whether there are synergies to gain from the current supply chain across their group companies.
• Competitive Positioning: The CDD report investigates the unique value propositions and market differentiation as well as the market positioning against competitors and peers in the industry.
• Management & Workforce Stability: Having access to the leadership team allows the CDD provider to assess the leadership team experience and determine who the key employees are to focus on retention strategies for the buyer.

A complete CDD report enhances buyer confidence in long-term sustainability and also provides insights into potential growth opportunities.

As the Due Diligence process concludes and the third-party reports are finalised, certain risks are identified which are classified as red flags. Depending on the scale or severity thereof, red flags can have a significant impact on the M&A process leading to further due diligence or potential price adjustments. It is therefore in the Sellers’ best interest to focus on the risks and the mitigation thereof by addressing these issues.

Some of the regular red flags are as follows:

• Unexplained Financial Discrepancies: Inconsistencies in revenue recognition, incorrect accounting methodologies or expense classifications.
• Legal & Regulatory Violations: Compliance breaches that could result in fines or reputational damage.
• Environmental risks: Companies that are involved in hazardous manufacturing or disposal of waste should assess these risks and ensure compliance within the necessary regulatory frameworks.
• Overreliance on a single customer or supplier.
• Employment issues or regular churn of employees and or key personnel.
• Unresolved Liabilities: Undisclosed debts, tax exposures, or pension obligations (especially Defined Benefit Pension schemes).

By addressing and implementing mitigation against these risks before buyer due diligence commences, allows sellers to improve their chances of securing a favourable valuation and smoother transaction.
