Due Diligence: A Critical Step Before Entering Any Business Partnership

In the business world, many companies rush into partnerships because they are tempted by market opportunities or competitive pricing.

Directors are often under pressure to quickly sign contracts so the business does not miss the opportunity. As a result, the investigation process before entering a partnership is often overlooked or carried out hastily.

In fact, on the ground, it is often found that partnerships that end in dispute originate from shallow due diligence. Hidden legal problems are only revealed after the contract has taken effect.

Discrepancies in a partner’s financial reports are sometimes discovered only during the annual audit. Reputational risks from vendors may even strike the company after the partnership is publicly announced.

During the negotiation stage, there is often an assumption that all business partners share the same standards of integrity. In reality, this assumption can be fatal if the partner turns out to have committed regulatory violations that ultimately harm the company.

For this reason, due diligence should not be regarded as merely an administrative formality, but rather as an essential step to reduce risk and ensure a secure long-term partnership.

What is Due Diligence?

Due Diligence is a process of thorough investigation, audit, and evaluation of a potential partner, acquisition target, or company with which a partnership is being considered, before a legal or financial commitment is made.

This process is conducted to ensure that all material information provided by the prospective partner, whether related to financial condition, legal status, operational capabilities, or regulatory compliance, accurately reflects the reality in practice.

In practice, due diligence is carried out in various types of business relationships. These range from venture capital investments in startup companies, corporate acquisitions by large corporations, procurement of information technology vendors, to long-term outsourcing partnerships.

Unlike a routine audit that focuses on periodic compliance, due diligence is investigative and in-depth because its results will be used as the basis for strategic decision-making.

As an illustration, when a company is considering working with an IT vendor to manage customer data, due diligence will reveal whether the vendor has adequate security certifications or has previously experienced a data breach incident.

This information will not typically be found in their sales presentations.

Types of Due Diligence

Due diligence consists of several types that are adjusted to the objectives and risks of each partnership. Each type has different examination focuses and methodologies.

1. Legal Due Diligence

Legal Due Diligence focuses on the legal aspects of the target company. The legal team will review the validity of business licenses, legal entity status, asset ownership, material contracts with third parties, and potential disputes that are ongoing or may occur.

In practice, it is often found that the target company does not have proper documentation for intellectual property ownership, or is actually facing a lawsuit that was not disclosed in the information memorandum.

Risks that often arise when legal due diligence is skipped include:

• Vendor contracts containing heavy penalty clauses
• Operational licenses that have not been renewed
• Legal disputes that have not been publicly disclosed
• Change-of-control provisions that can invalidate contracts during an acquisition

In the context of acquisitions, a single overlooked clause can result in legal liabilities worth millions of dollars after the transaction is completed.

2. Financial Due Diligence

Financial Due Diligence is conducted to verify the accuracy of financial statements. Auditors and financial analysts will trace cash flow, debt structure, problematic receivables, and the reasonableness of assumptions used in financial projections.

Risks that may be identified in financial due diligence include:

• Financial statements that do not reflect the company’s actual business condition
• Hidden debts or unresolved tax obligations
• Unstable cash flow despite high reported revenue
• Revenue dependency on one or two major customers

In startup investments, for example, adjustments to revenue recognition can drastically change the company’s valuation.

3. Operational Due Diligence

Operational Due Diligence examines core business processes, supply chains, and the company’s dependency on certain parties. This evaluation is particularly important when the partnership aims to integrate the operations of both companies.

In many cases, operational due diligence may uncover risks such as:

• Dependency on a single critical supplier without a long-term contract
• Standard operating procedures that are not documented
• High employee turnover in key positions
• Weak internal control systems

In outsourcing partnerships, failure to understand a partner’s operational capacity can lead to service disruptions and reputational losses.

4. IT / Cyber Due Diligence

IT and Cyber Due Diligence have become increasingly critical as businesses continue to digitize their operations. Technical teams will examine technology infrastructure, data security architecture, compliance with data protection regulations, and potential security vulnerabilities.

In partnerships with technology vendors, it is often discovered that the proposed system does not have the required security certifications or even uses unlicensed software components.

The risks that may arise include:

• Legacy systems that are not scalable
• Unresolved security vulnerabilities
• Non-compliance with personal data protection regulations
• Dependency on a single technology vendor

During the evaluation of digital business partners, it is often found that the target company lacks adequate access controls or has never conducted penetration testing.

5. Reputational Due Diligence

Reputational Due Diligence investigates the track record of the company and its owners in the eyes of the public, regulators, and the market.

This investigation includes negative media coverage, legal records of shareholders, and business practices that may create conflicts of interest.

Ignoring reputational aspects may result in a company becoming associated with partners suspected of engaging in corruption or money laundering practices.

Risks that frequently emerge include:

• Directors previously involved in legal cases
• Unethical business practices
• Viral labor or employment issues
• Relationships with high-risk parties

In the era of information transparency, reputational risk can directly affect share value, investor trust, and customer loyalty.

Objectives of Due Diligence

The primary objective of due diligence is to identify and measure risks that are not visible in ordinary documents before a business commitment is made, ensuring that decisions are informed and strategic.

Specifically, these objectives include:

1. Identifying Hidden Risks

Hidden risks often cannot be seen in presentations or executive summaries. For example, unresolved tax obligations or unfavorable long-term contracts.

In evaluating business partners, such findings can become the basis for adjusting the transaction structure or requesting additional guarantees.

2. Measuring Realistic Valuation

Company valuation is not determined solely by revenue, but by the quality and sustainability of that revenue.

If financial due diligence reveals that 40% of revenue comes from a single major customer whose contract is close to expiration, that concentration risk must be reflected in the transaction price.

3. Avoiding Legal Burdens After the Transaction

Without legal due diligence, a company may inherit legal disputes or obligations that were previously undisclosed. The impact is not only financial but also reputational and operational.

In some acquisitions, legal liabilities discovered after the transaction resulted in litigation costs exceeding the expected synergy value.

4. Becoming the Basis for Renegotiation

Due diligence findings often change the dynamics of negotiations. Identified red flags may be used to:

• Reduce the acquisition price
• Change the payment structure into staged payments (earn-out)
• Request indemnity or additional guarantees
• Postpone the transaction until the risks are resolved

Therefore, due diligence is not merely a verification tool but also a strategic instrument in decision-making.

Stages of Conducting Due Diligence

Due diligence is carried out systematically and in stages to ensure that no material aspect is overlooked. Each stage has a specific objective and involves professionals with expertise relevant to the area being examined.

1. Determining Scope and Objectives

Before the investigation begins, the management team together with consultants or internal auditors must agree on the focus of the due diligence.

Questions include: Is the process intended to verify the accuracy of financial reports, examine legal compliance, or evaluate technological capabilities?

Determining the scope will influence what documents need to be requested and what type of experts should be involved.

For example, acquiring 100% of a company’s shares requires a far more comprehensive evaluation compared to partnering with a non-critical vendor.

2. Requesting Documents and Data

The prospective partner or acquisition target will be asked to provide data through a request list (due diligence checklist), which may include historical financial statements, legal documents, material contracts, certifications, asset ownership evidence, and internal policies.

In practice, not all documents are provided completely at the initial stage. It is often found that the target company needs time to compile the data or may even hesitate to provide certain documents due to confidentiality reasons.

3. Analysis and Verification

Once the documents are collected, the team performs analysis and verification. The provided data is not automatically accepted as fact but must be verified through third-party confirmations, supporting document tracing, or interviews with management.

In financial audits, the team may confirm receivable balances directly with the target’s customers. In legal due diligence, the team may independently check case statuses in court records.

4. Identification of Red Flags

The identification of red flags is the stage of interpreting the findings. A red flag is an early indication of a potentially serious problem.

Red flags may include data inconsistencies, undisclosed legal disputes, excessive dependency on a single customer, IT systems without a disaster recovery plan, or business practices that may violate regulations.

Not every red flag will halt a partnership. However, each red flag must be investigated further to assess its severity and determine mitigation strategies.

5. Preparation of Report and Recommendations

The final stage is preparing the report and recommendations. A due diligence report does not only contain factual findings but also analysis of the risk impact on the partnership and recommended follow-up actions.

In such reports, the team may recommend proceeding with the acquisition at an adjusted price, requiring the partner to resolve certain legal issues before signing the contract, or even canceling the partnership if the risks are too significant and cannot be mitigated.

For directors and the board, this report becomes the basis for the final decision before signing the definitive agreement.

Conclusion

Due Diligence is a comprehensive evaluation process aimed at identifying, measuring, and managing risks before a business partnership is finalized.

In practice, many failed investments and strategic partnerships are not caused by a lack of market opportunity, but by risks that were not identified from the beginning.

Hidden legal problems, inaccurate financial statements, operational weaknesses, and reputational risks can erode transaction value and business stability.

Ultimately, due diligence functions as a safeguard for business strategy. Evaluating potential partners ensures that the growth being pursued is not built upon uncontrolled risks.

Before signing a contract, the key question should not be “how big the opportunity is,” but rather “how measurable the risks are.”

This is where due diligence becomes a responsible and sustainable decision-support tool.
