Audit and assurance engagements run on documents, deadlines, and careful coordination. An audit team arriving at a client site — or beginning a remote audit — must have access to a defined set of financial records, reconciliations, and supporting documentation before substantive testing can begin. The process of identifying, requesting, tracking, and confirming the receipt of that documentation is a significant operational function that, when handled poorly, leads to extended fieldwork timelines and scope creep.
In 2026, audit and assurance firms are deploying virtual assistants to manage the pre-engagement and concurrent administrative functions that enable efficient fieldwork — without pulling audit seniors and managers into logistics they should not be handling.
Client Intake and Engagement Planning Support
Before an audit engagement begins, the firm must execute engagement letters, confirm independence, identify key contacts at the client organization, and establish the communication protocols that will govern the engagement. This intake process has both technical and administrative components.
Virtual assistants handle the administrative components: sending engagement letters, tracking e-signature completion, confirming billing and contact information, and scheduling the planning meeting between the audit manager and the client's finance team. For recurring audit clients, VAs manage the annual re-engagement cycle — sending the updated engagement letter, confirming any scope changes, and updating contact records with personnel changes at the client.
The Center for Audit Quality's 2025 practice efficiency report found that audit teams at firms with dedicated engagement coordinators or VAs completed pre-engagement setup 30% faster than teams without that support.
Prepared-by-Client Document Collection
The prepared-by-client (PBC) request list is the lifeblood of an audit engagement. Audit teams request dozens to hundreds of documents from client finance departments, and tracking which items have been received, which are still outstanding, and which require clarification is a constant operational challenge.
Virtual assistants can own the PBC tracking process. They distribute the initial PBC list at engagement start, create and maintain a tracking log in the firm's engagement management system, send follow-up reminders on a defined schedule, and flag overdue items to the audit manager. When documents arrive, VAs log receipt, confirm they match the request specifications, and notify the audit team that materials are ready for review.
For large audit engagements with PBC lists of 100 or more items, this tracking function alone represents significant work. One regional firm profiled in a 2026 Accounting Today feature estimated that VA-managed PBC tracking saved their audit teams 12 to 15 hours per engagement, across a portfolio of 60 annual audits.
Audit Scheduling and Team Coordination
Audit scheduling involves coordinating between the audit firm's team calendar and the client's availability — particularly for field visits, walkthrough meetings, inventory observations, and closing conferences. Getting these logistics right prevents the costly scenario of an audit team arriving at a client site with key personnel unavailable.
Virtual assistants manage audit scheduling logistics. They coordinate field visit dates with client controllers and CFOs, confirm availability for walkthrough interviews with process owners, schedule inventory observations with warehouse management, and distribute meeting agendas and preparation requests to all parties in advance.
For firms managing multiple simultaneous engagements, VAs maintain a master scheduling dashboard that gives audit managers visibility into team deployment across all active engagements — a planning tool that reduces scheduling conflicts and improves resource utilization.
Communication with External Parties
Audit engagements require communication with third parties: legal counsel (for representation letters and contingency disclosures), financial institutions (for bank confirmations), accounts receivable confirmations, and investment custodians. Managing this correspondence requires systematic follow-up.
Virtual assistants prepare and distribute third-party confirmation requests, track response status, follow up on non-responses, and maintain a confirmation log for the audit workpaper file. For firms using electronic confirmation platforms like Confirmation.com, VAs handle the platform setup and monitoring functions. This systematic approach to third-party communication reduces confirmation response time and ensures that confirmation exceptions are identified and communicated to the audit team promptly.
Protecting Audit Senior and Manager Time
Audit senior and manager time is among the most expensive resources in a public accounting firm. Billing rates for these professionals typically range from $150 to $300 per hour at regional firms and higher at national firms. Administrative coordination tasks billed at these rates represent a significant cost to clients that could be handled at a fraction of the cost by a skilled VA.
For audit and assurance firms committed to protecting high-value staff time while maintaining engagement quality, Stealth Agents provides virtual assistants trained in audit engagement workflows, PBC tracking, and engagement scheduling coordination.
