Internal Audit Teams Are Stretched Thin
Internal audit functions are under increasing pressure to expand audit coverage across growing organizational complexity — more business units, more regulatory requirements, and more technology risks — while headcount budgets remain flat. A 2024 Institute of Internal Auditors (IIA) Global Internal Audit Common Body of Knowledge (CBOK) study found that 61% of internal audit departments reported their audit coverage was insufficient relative to their risk universe, with staffing constraints cited as the primary limiting factor.
The gap between the audit work that needs to be done and the auditor capacity available to do it is real — and virtual assistant support is emerging as one practical way to close it.
Where VAs Fit Into the Internal Audit Workflow
Internal auditors are finding that the administrative and documentation-intensive phases of the audit cycle can be effectively delegated without compromising the independence and judgment that define audit quality. Tasks commonly handled by VAs in internal audit environments include:
- Evidence request and collection: Sending preliminary client information request (PBC) lists, following up on outstanding items, organizing received documents, and tracking completion status in the audit management system.
- Workpaper formatting and file assembly: Formatting workpapers according to department templates, cross-referencing supporting documents, and maintaining organized electronic audit files.
- Audit tracking and status reporting: Updating audit status dashboards, populating audit-in-progress trackers, and preparing status summary slides for audit management meetings.
- Finding and recommendation documentation: Converting auditor field notes into first-draft formatted observation write-ups for senior auditor review and editing.
- Follow-up and remediation tracking: Sending management action plan follow-up reminders, tracking commitment status, and maintaining remediation logs ahead of closing meetings.
Audit Coverage and Output Improve Measurably
A 2025 Protiviti Internal Audit Capabilities and Needs Survey found that internal audit functions using outsourced support for documentation and administrative tasks completed an average of 18% more audits per year compared to fully in-house teams of equivalent size. The same survey noted that average workpaper quality scores — measured in external peer review — were higher at teams where administrative work was handled by dedicated support staff.
"We were spending 40% of our fieldwork time on PBC chasing and workpaper formatting," said a director of internal audit at a publicly traded manufacturing company, speaking with the Virtual Assistant Industry Report. "After bringing in VA support for those tasks, we completed three additional audits last year with the same audit team."
Skills That Make a Strong Internal Audit VA
Internal audit environments require VAs with exceptional attention to detail, comfort with document management, and a clear understanding of confidentiality obligations. Experience in legal administration, compliance support, or finance operations provides a strong foundation.
Familiarity with audit management platforms such as TeamMate, AuditBoard, or Workiva is a significant advantage. VAs who understand the structure of audit documentation — what belongs in a workpaper, what the tick-mark system represents, how evidence links to audit objectives — can produce higher-quality output from day one.
The Economics of Audit Support
A staff internal auditor in the U.S. earns $65,000 to $90,000 annually plus benefits, per the 2025 IIA Compensation Study. A qualified VA providing audit support services typically costs $12,000 to $25,000 per year through a managed provider. For audit departments trying to close the gap between their risk universe and their coverage capacity, the cost differential makes VA support one of the most efficient headcount-equivalent investments available.
Protecting Audit Independence and Confidentiality
Audit documentation is sensitive, and audit independence is a professional obligation. VA integrations in internal audit must ensure that VAs are not making any audit judgment calls — their role is strictly administrative and documentation-based. All VA work product must be reviewed and approved by a licensed auditor before it becomes part of the official audit file.
Data access should be limited to the specific audit project files the VA is supporting, with no access to unrelated organizational information. NDAs and confidentiality agreements are standard requirements.
Building the Case for VA Support in Audit
Many internal audit directors find that the easiest way to demonstrate VA value is to run a pilot on a single audit — delegating PBC management and workpaper formatting — and track the time savings against the VA cost. The ROI case becomes self-evident within a single audit cycle.
Internal auditors and audit directors looking to expand coverage without adding permanent headcount can explore pre-vetted VA support at Stealth Agents, with remote professionals experienced in financial services and compliance documentation and onboarding designed for the audit environment.
