CPA Firms Are Understaffed by Design—And It's Getting Worse
The AICPA PCPS 2026 CPA Firm Management Survey reports that 74% of firms with fewer than 20 professionals cite staff capacity as their top growth constraint. With accounting pipeline talent declining—CPA exam candidates dropped 17% between 2021 and 2025 according to NASBA—firms are unlikely to solve this challenge by simply hiring more accountants.
The practical response is workflow reengineering: moving non-CPE administrative tasks off the plates of licensed professionals and onto lower-cost support roles. Virtual assistants are increasingly filling that support layer, handling the process management work that keeps a firm running without requiring an accounting credential.
Four High-Volume Administrative Workflows for CPA Firm VAs
Client onboarding at an accounting firm involves more steps than most clients realize. New engagement setup includes conflict check coordination, entity documentation collection (formation documents, EIN letters, prior-year returns), software access provisioning (QBO, Xero, client portal setup), and introductory meeting scheduling. Without a defined owner, these steps get distributed across multiple team members—inconsistently and slowly.
A virtual assistant runs the onboarding checklist from start to finish: sends welcome sequences, collects required documents via secure portal, confirms software access, and hands off to the engagement manager with a complete intake package. AICPA data shows firms with structured onboarding processes retain 31% more clients through year two than those without.
Engagement letter tracking is one of the most overlooked administrative gaps in accounting firms. Engagement letters must be executed before work begins—but tracking who has signed, who hasn't, and following up on overdue signatures falls through the cracks when no one owns the process. A VA sends engagement letters via DocuSign, monitors execution status, sends follow-up sequences at defined intervals, and escalates to the partner when a letter remains unsigned past the deadline.
Payroll deadline reminders are critical for firms with payroll clients. Missing a 941 deposit deadline or a state payroll tax filing date creates penalties that damage the client relationship and expose the firm to liability claims. A VA maintains the payroll deadline calendar, sends automated reminders to clients 5 and 2 days before each deadline, and confirms receipt of payroll data—giving payroll staff the lead time they need to process without last-minute scrambles.
Audit document collection is one of the most document-intensive workflows in public accounting. PBC (Prepared by Client) lists for an audit engagement can include 50–150 line items collected from multiple departments. A VA manages the PBC tracker, sends requests to client contacts, follows up on outstanding items, confirms receipt, and updates the audit team's document management system—keeping the audit timeline on track without the senior auditor spending hours on client follow-up.
The Staffing Math
The AICPA PCPS survey benchmarks average administrative staff salaries at $48,000–$62,000 for full-time firm administrators. Virtual assistants from specialized providers typically cost $12,000–$20,000 annually for equivalent full-time coverage—a savings of $28,000–$42,000 per role before benefits.
For a 10-person CPA firm running 3–4 concurrent audit engagements plus 200+ tax and bookkeeping clients, even one full-time VA dedicated to onboarding, letter tracking, and document coordination can recapture 400–600 billable hours annually that would otherwise be absorbed by professional staff.
