Supply Chain Audits

Our supply chain audit services go beyond simple questionnaires, providing evidence-based assurance that your suppliers meet their contractual and regulatory requirements.

What is supply chain auditing?

A supply chain audit refers to a thorough evaluation of the working practices of an organisation’s suppliers. These audits review processes, systems, documentation to identify whether suppliers comply with internal policies, contractual obligations and regulatory requirements.

Supply chain audits are essential part of third-party risk management and the procurement process. They help organisations anticipate problems that could result in disruptions, reputational damage and legal consequences. Thorough audits therefore provide assurances in your suppliers’ practices and ensure operational resilience.

FAQs

A vendor questionnaire is self-reported. They complete a series of Yes/No questions regarding their operations. An audit is a formal examination of an organisation’s practices – and verified by a third party (i.e. GRC Solutions) with evidence and observations.

A questionnaire can give you an idea of how robust a supplier’s practices are. It can filter out high-risk vendors and is often part of due diligence during the onboarding process.

The duration varies based on the size of the organisation, the complexity of its supply chain, and the specific scope of the audit. We tailor every engagement to meet your specific timelines.

It is usually helpful to give suppliers advance notice of an upcoming audit, and this is something we will manage as part of the engagement process.

By notifying suppliers in advance, we ensure that the relevant personnel are available and can provide the necessary information to the auditor, preventing delays and ensuring the audit is comprehensive and effective.

Although you will need to allocate some time to help prepare for the supply chain audit, it should not result in significant disruptions. Using a third party like GRC Solutions limits internal delays; once we understand your requirements, our experts progress with the assessment while your team focuses on its core business.

Similarly, your suppliers will need to set aside time to provide the necessary information or access to the auditor, but the disruption will be minimal.

Our supply chain audits are based on the best-practice information security standards ISO 27001 and ISO 27701, giving you the confidence that risks that arise through your supply chain will be identified and minimised.

We can design an audit programme around your risks and controls and seek answers from your suppliers and processors about their practices. You will receive a report that identifies areas of good practice and highlights deficiencies, supported by recommendations to resolve or mitigate them.
