Vendor due diligence: Your ultimate checklist

Vendor due diligence is essential in mitigating risks and securing your business operations. With mounting regulatory demands and shifting market conditions, understanding how to assess vendor risks and compliance is more critical than ever. 

This blog post is your starting point for integrating due diligence into your business practice, offering strategies without disclosing specific checklist items too early.

Key takeaways

  • Vendor Due Diligence (VDD) is essential for assessing the financial stability, legal status, operational integrity, regulatory compliance, and reputation of third-party vendors, which helps in risk management and informed decision-making.
  • The scope of VDD is broadening, with Environmental, Social, and Governance (ESG) considerations and data protection increasingly becoming integral to assessing vendor risks, due to stricter regulations like GDPR, HIPAA, and CCPA.
  • Effective VDD involves continuous risk management, including categorizing vendor relationships, focusing more on high-risk vendors, using technology and automation for more efficiency, and being prepared with a comprehensive due diligence checklist and consistent monitoring post-onboarding.

Understanding vendor due diligence: An overview

Vendor Due Diligence (VDD) forms the basis of a secure vendor selection process. It helps you assess third-party vendors in terms of their:

  • Financial risk and stability
  • Legal standing
  • Operational robustness
  • Regulatory compliance
  • Reputational aspects

This process provides a solid foundation for informed decision-making, effective risk management, and enhanced operational efficiency.

The due diligence process primarily includes regulatory compliance assessments and, depending on the situation, may also include:

  • Systematic background checks
  • Financial analysis
  • Legal review

Together, these steps are crucial for an unbiased analysis of a particular vendor. Conducting thorough due diligence safeguards your business from unnecessary risks and preserves your reputation. After all, your vendors’ actions could significantly impact your company’s reputation.

The expanding scope of vendor due diligence requirements

The scope of vendor due diligence process continues to evolve, adapting to the ever-changing business landscape. 

For example, one critical development is the incorporation of Environmental, Social, and Governance (ESG) considerations into vendor due diligence. ESG factors have become a significant part of vendor risk assessments, as they can impact operational, regulatory, and reputational factors. From managing natural resources to observing ethical labor practices, these factors can significantly influence a vendor’s reputation and operational efficiency.

Another crucial expansion of vendor due diligence is data protection. With regulations like GDPR, HIPAA, and CCPA becoming more stringent, businesses are emphasizing vendor due diligence to guard against breaches involving Personal Health Information (PHI) and Personally Identifiable Information (PII).

As the landscape of vendor risk management continues to evolve, it is incumbent upon organizations to similarly evolve their approach to vendor due diligence to keep pace with these changes.

Who conducts the vendor due diligence process?

Conducting vendor due diligence has a variety of approaches. Depending on your internal expertise, resources, and risk priorities, you can opt for in-house, outsourced, or hybrid strategies for vendor due diligence.

In-house vendor due diligence allows you to verify the vendor’s claims directly; identifying unethical practices and verifying regulatory compliance. On the other hand, outsourcing the process leverages external expertise, freeing up your internal resources to focus on risk mitigation.

Hybrid strategies offer the best of both worlds, combining in-house, shared, and outsourced methods for a comprehensive risk management program. This approach ensures a tailored and robust risk management plan that suits your organization’s unique needs.

Key components of a vendor due diligence checklist

Vendor due diligence is done both initially, at the start of a new vendor relationship, and continually, as an ongoing best practice:

  1. Initial due diligence — As it sounds, this is when you first meet with a vendor and verify that they’ll meet your needs prior to an engagement. This initial discussion should help identify risk and determine if the vendor would be a good partner for your organization and if they meet your strategic and financial standards.
  2. Ongoing due diligence Continuous monitoring should be top of mind when you work and build a relationship with a third-party organization. You should continuously monitor and analyze your vendors, even if they have already been contracted. One example of continuous monitoring would be to incorporate this as a key step in your annual compliance assessments. However, the frequency of analysis can be dependent on the risk level of the vendor.

The due diligence checklist

A vendor due diligence checklist should include:

  • Basic company information, such as a business certificate or license
  • Details about executives and board members
  • Location
  • Character references (if applicable)
  • Incorporation documents
  • An overview of the corporate structure

This checklist guides the sales process of conducting comprehensive and consistent evaluations of prospective vendors.

Financial due diligence forms another crucial part of the checklist. It involves reviewing the vendor’s:

  • Compensation structure
  • Major assets
  • Loans and obligations
  • Balance and accounting sheets
  • Important tax documents

This is done to assess their financial stability. Publicly traded companies should be monitored through quarterly filings, while private companies should regularly provide financial reports for ongoing financial transparency.

Lastly, the checklist should also include:

  • Data security and operational risk assessments
  • Legal and reputational risk management
  • Evaluating compliance, data security practices, and the vendor’s operational risk management
  • Routine checks for litigation or enforcement actions involving the vendor

Implementing a risk-based approach to vendor due diligence

Adopting a risk-based approach is a critical component of effective vendor due diligence. This involves assessing the types and severity of risks posed by vendors prior to selection and onboarding.

To facilitate this, effective vendor relationships can be categorized into tiers, with more resources and efforts focused on high-risk vendors. This ensures that the greatest potential harm to the business is addressed first, aided by the use of vendor risk intelligence networks.

In addition to the items listed in the previous section, robust due diligence for high-risk vendors can include:

  • Verification of anti-money laundering (AML) compliance
  • Customer due diligence processes
  • Regulatory compliance checks
  • Adopting preventive measures for identified risks

Continuous monitoring and open communication between relevant internal stakeholders, such as procurement, legal, and IT departments, are also crucial for consistency in adopting and adapting a risk-based due diligence approach.

Continuous monitoring and management of vendor risks

As already mentioned, it’s essential to extend the process of managing vendor risks beyond initial due diligence. Continuous monitoring is a strategic discipline that ensures vendors meet performance expectations and that potential risks are proactively identified and mitigated. 

Monitoring techniques may include: 

  • Establishing data breach notification protocols
  • Setting up Google Alerts for vendors
  • Adapting to changes in the security posture

Disaster recovery plans, employee training protocols, and due diligence conducted on subcontractors should also be part of operational risk assessments. 

Real-time risk intelligence plays a crucial role in risk management. For instance, a technology company that proactively monitors vendor cybersecurity may be able to avoid a data breach, illustrating the value of real-time risk intelligence in better risk management outcomes.

Leveraging technology and automation in vendor due diligence

Automated third-party risk management platforms can streamline vendor due diligence processes, as they offer:

  • Visual dashboards for efficient risk oversight
  • Automation that can speed up the due diligence process
  • Automated questionnaires powered by artificial intelligence enable faster assessments and high-quality responses, reducing the time spent on manual data entry and increasing the accuracy of risk profiling.
