Outsourced and Co-sourced Internal Audit
Efficient – Objective – Compliant
Service and product description
Our Outsourced and Co-sourced Internal Audit services support businesses by either fully performing internal audit functions or partnering with your existing internal audit team to ensure effective risk control and compliance. This service helps businesses save costs, enhance audit quality, and focus on core activities.
At Crowe Vietnam, we apply a globally unified internal audit methodology:
- Outsourced Internal Audit: Crowe Vietnam performs the entire internal audit function, including evaluating processes, risk management, internal controls, and regulatory compliance, without requiring an in-house internal audit team. We coordinate and report directly to the Head of Internal Audit and/or the Audit Committee/Board of Directors.
- Co-sourced Internal Audit: Under this model, Crowe Vietnam collaborates with, supports, and supplements the client’s internal audit team with additional resources, expertise, and experience. The goal is to ensure an efficient, objective, and compliant audit process.
Our methodology focuses on risk-based auditing, addressing client objectives and the challenges in achieving them. Internal audit delivery can take various forms, each offering different levels of ownership and combinations of fixed and variable costs.
Context for utilizing our services
Outsourced Internal Audit: Typically for businesses seeking to fully outsource their internal audit plan to gain advantages such as (1) meeting work deadlines, (2) saving time and effort for leadership, (3) reducing costs, (4) ensuring higher work quality, (5) enhancing objectivity and independence, and (6) leveraging the reputation and credibility of an established audit service provider.
Co-sourced Internal Audit: Typically for businesses that have an internal audit department but lack sufficient staff or specialized expertise. They may need support due to (1) limited expertise in IT, data analytics, regulatory knowledge, or (2) difficulty and high costs associated with recruiting, developing, and retaining qualified audit personnel.

Service process
Step 1: Risk Assessment
Conduct a risk assessment to understand the key risks facing the business. This step identifies critical areas to audit, optimizing resources and time during the internal audit process.
Step 2: Planning
Based on the risk assessment, we develop a detailed audit plan, including scope, timeline, and required resources. The plan is discussed and agreed upon with the client to ensure it meets expectations.
Step 3: Execution
Our auditors carry out the planned audit activities, from data collection and analysis to reviewing processes and compliance with applicable regulations and standards. We work closely with the client’s internal audit team to ensure a smooth and efficient process.
Step 4: Reporting & Deliverables
After completing the audit activities, we discuss findings, results, and recommendations with the client. A detailed audit report is issued to provide clear insights into the company’s risk management and internal control systems, along with improvement suggestions.
Timeline for service delivery
The service timeline depends heavily on the project scope, client feedback, and the level of collaboration (including involvement of suppliers, customers, lenders, or investors).
Typically, we complete this service within 4 – 6 weeks for most cases. For urgent requests, we apply special measures such as mobilizing additional resources, flexibly adjusting processes, and requiring active cooperation from the client to ensure timely and successful delivery.
