Confirming Vendor Readiness Before Commitment

April 2025  |  Reading time: 2 minutes

Even after thorough evaluations, proposals, and testing, one critical step remains before finalizing a vendor: the Vendor Audit. This phase provides assurance that the selected supplier can consistently maintain GxP compliance and support regulatory expectations.

A system may look great in a demonstration, but if the vendor lacks proper quality management, validation processes, or security controls, long-term compliance risks could arise. A well-executed vendor audit helps identify these risks and ensures they are addressed before moving forward.

Phase 6: Vendor Audit

Planning & Performing the Vendor Audit

The first step in this phase is conducting a structured on-site or remote audit of the vendor’s Quality Management System (QMS), Software Development Life Cycle (SDLC), and validation documentation. The goal is to verify that the vendor follows robust quality processes and adheres to industry best practices. This includes assessing their change management procedures, issue resolution processes, and how they handle deviations. A vendor with well-documented, repeatable processes is far more likely to maintain compliance in the long run.

Reviewing SOPs, Validation Documentation & Infrastructure Controls

A deeper look into the vendor’s Standard Operating Procedures (SOPs), validation documentation, and security measures provides further insights into a vendor’s compliance readiness. You should review critical documents such as Installation Qualification (IQ), Operational Qualification (OQ), and Performance Qualification (PQ) protocols to ensure the system is properly validated. Additionally, infrastructure security controls (such as: data encryption, access management, and backup procedures) must be assessed to confirm that the vendor can safeguard sensitive GxP data.

Identifying Risks & Defining Mitigation Actions

Every audit reveals findings, whether minor observations or significant compliance gaps. The key is to document these risks, classify their severity, and work with the vendor to implement corrective actions. If issues arise, organizations must determine whether they are deal-breakers or manageable risks that can be mitigated through contractual agreements, process changes, or additional validation efforts. Engaging in open discussions with the vendor helps clarify expectations and ensures alignment before the final selection.

Wrapping Up Phase 6

A vendor audit is more than just a regulatory checkpoint. It’s a critical risk management tool. Ensuring that a vendor has strong quality controls, secure infrastructure, and validated processes minimizes long-term compliance risks and operational disruptions.

With the audit complete and necessary mitigations in place, you are now ready to move to the next step: Final Selection and Contracting.
