Key Takeaways
- There are six main ways to hire an offshore executive assistant: freelance marketplaces, managed offshore agencies, direct hiring through job boards, referral networks, nearshore hiring, and hybrid trial approaches.
- Freelance platforms like Upwork provide flexibility and quick access to talent but require you to handle vetting, onboarding, and management.
- Managed offshore agencies cost more but reduce hiring effort by handling screening, training, and ongoing quality oversight.
- Direct hiring through job boards offers the lowest long-term cost but requires significant time investment for recruiting, training, and management.
- Nearshore hiring in regions like Latin America allows real-time collaboration with US time zones but typically costs more than traditional offshore options.
- The best hiring method depends on your available time, risk tolerance, budget, and how much management capacity you have for vetting and onboarding assistants.
CPA firm owners typically bill $200-$500 per hour, but industry data shows they spend 8-12 hours per week on administrative work that does not require their expertise. At $229 per hour (the industry average for CPA firm owners per practice management surveys), 10 admin hours per week adds up to roughly $2,290 in foregone billing every week. This article shows you how to calculate that number for your specific rate and what it changes.
Why CPA firm owners do more admin than they realize
Most CPA owners think they spend 2-3 hours a week on admin. Time tracking studies suggest the real number is 8-12. The gap exists because admin hides inside otherwise billable time.
The invisible admin categories that hide inside a CPA week
Administrative work is not one block on your calendar. It is scattered across dozens of micro-interruptions that individually feel fast but collectively consume hours you never record. Scheduling a client follow-up takes three minutes. Chasing a missing document takes five. Formatting a report takes twenty. None of these show up on a timesheet as “admin.”
Arvori’s CPA pricing and utilization research indicates that CPA professionals bill only 55-70% of their working time in most small firm settings, meaning 30-45% is absorbed by admin, coordination, and overhead that never appears as revenue. The invisible categories eating your week include:
- Inbox triage and client email responses that require coordination but not professional judgment.
- Calendar management, including rescheduling, timezone coordination, and meeting prep logistics.
- Document chasing, status follow-ups, and reminder sequences for outstanding client deliverables.
- Report formatting and template population that requires data entry, not analysis.
- Client onboarding coordination, intake form management, and portal access setup.
Why the first hour of every day is often non-billable
The first hour of a CPA owner’s day is structurally administrative. Inbox review, voicemail follow-up, and calendar confirmation do not generate billable output. They generate readiness. Five hours per week of morning coordination, applied against a $229 billing rate, represents over $1,100 in foregone revenue before a single advisory task starts.
How tax season amplifies the admin problem
Tax season does not change the type of admin that falls on a CPA owner. It changes the volume and the cost of delay. Document follow-up that takes ten minutes in September takes forty in March, and every admin hour during Q1 and Q2 carries a higher opportunity cost because the billable queue behind it is longer.
How to calculate your true admin cost in 15 minutes
Take your billing rate and multiply it by the number of admin hours you spend each week. That number is not a productivity metric. It is a direct revenue loss.
Step 1: Track admin time for one week using six specific categories
Do not estimate. Track. Use a simple time log, a notes app, or a sticky note by your monitor. Every time you switch to a task that does not require your credential to complete, log it. The six categories to track:
- Scheduling and calendar management: Any time spent booking, moving, or confirming meetings.
- Inbox processing: Emails that required reading and responding but not professional advice.
- Document follow-up: Any time spent requesting, reminding, or chasing client documents.
- Report and template formatting: Time spent populating documents you did not analyze.
- Client onboarding logistics: Portal setup, intake coordination, access provisioning.
- Internal coordination: Staff check-ins and workflow follow-up not involving direct client work.
Step 2: Apply your billing rate to get the weekly cost
TaxDome’s data on what CPAs charge per hour by service type confirms billing rates typically run $200-$500 depending on service type, complexity, and geography. Once you have your weekly admin hours, the formula is straightforward:
Weekly admin cost = Billing rate x Admin hours per week
| Billing Rate | 8 hrs/week | 10 hrs/week | 12 hrs/week |
| $175/hr | $1,400 | $1,750 | $2,100 |
| $200/hr | $1,600 | $2,000 | $2,400 |
| $229/hr (avg) | $1,832 | $2,290 | $2,748 |
| $250/hr | $2,000 | $2,500 | $3,000 |
These are not projections. They are what those hours are worth at your current billing rate when redirected to client work.
Step 3: Project it over a quarter and compare it to EA cost
Multiply your weekly admin cost by 13. A CPA billing $200/hr who spends 10 hours a week on admin loses $26,000 in billable capacity per quarter, not from lack of clients, but because those hours are occupied by tasks that do not require a credential.
What an offshore executive assistant costs by comparison
A full-time offshore EA through a managed provider typically costs $1,200-$2,000 per month. At $229/hr billing, reclaiming just six admin hours per week pays for the EA in full.
Monthly cost of an offshore EA vs. monthly cost of doing it yourself
Multiply your weekly admin cost by 4.3 to get your monthly number. A CPA billing $200/hr who spends 10 hours per week on admin absorbs $8,600 per month in foregone billable capacity. Against a $1,200-$2,000/month EA, that spread is not close. The full breakdown of what an offshore EA costs for CPA firms covers the variables worth understanding before you commit, and how much a virtual EA costs in 2026 maps the full range from freelance to managed offshore.
The breakeven point for CPA firm owners at $175, $200, and $250/hr
At a $1,500/month EA cost, breakeven arrives in under two hours of reclaimed admin per week at any common CPA billing rate:
| Billing Rate | Monthly EA Cost | Hours/week to break even |
| $175/hr | $1,500 | 2.0 hrs/week |
| $200/hr | $1,500 | 1.7 hrs/week |
| $250/hr | $1,500 | 1.4 hrs/week |
The offshore vs US-based EA cost comparison shows why the offshore option changes the math: a US-based EA at $3,500-$5,000/month moves breakeven considerably higher, while offshore sits well inside it at most CPA billing rates.
What reclaiming time actually means in dollars at different rates
Reclaiming admin hours only generates revenue if those hours move to billable work. For most CPA firm owners with a client queue, that condition is already met. If your schedule has open capacity, recovered hours go toward business development or new client onboarding. Either way, the hours have value. The admin version of those same hours does not.

Which admin tasks a CPA firm owner can actually delegate
Not everything on your plate can move to an EA. The delegate list is longer than most CPA owners expect.
Tasks that transfer immediately: scheduling, inbox, document follow-up
These transfer on day one because they require access to your tools and an understanding of your preferences, not your credential. The full inventory of tasks to delegate to an EA covers the complete transfer list across scheduling, communications, and operations. The immediate-transfer category includes calendar management, inbox triage, document follow-up sequences, CRM updates, and portal access provisioning.
Tasks that transfer with a documented process: report formatting, client onboarding prep
New client intake follows the same sequence every time: send the engagement letter, request the prior-year return, provision portal access, schedule the kickoff call. An EA can own all four steps within the first month, returning several hours per new client that currently land on you. Report formatting transfers the same way: one documentation session produces a repeatable process your EA runs without your involvement going forward.
Tasks that stay with you: client-facing advice, compliance decisions, sign-offs
The advisory function, compliance judgment, and final sign-off authority stay with the CPA. The guide on tasks CPAs should never delegate draws that line clearly and is worth reviewing before you build your delegation protocol. Deciding whether hiring an EA is worth it comes down to how many hours per week fall into the delegatable categories. Above five hours at a billing rate above $150/hr, the math closes before the first month ends.
Frequently asked questions
How many hours per week do CPA firm owners spend on admin?
Industry research suggests 8-12 hours per week, though most owners underestimate this because admin time is fragmented across a day rather than appearing as a blocked calendar slot.
What is the average billing rate for a CPA firm owner?
Practice management surveys put the average at approximately $229 per hour, with rates ranging from $150 for small regional firms to $500 or more for senior specialists.
How much does an offshore executive assistant cost per month?
Full-time offshore EA support through a managed provider typically costs $1,200-$2,000 per month; direct offshore hires run lower but add management overhead that narrows the savings.
Can a CPA firm owner delegate client communication to an EA?
Yes, for the coordination layer. Scheduling, follow-up emails, and document chasing all transfer cleanly, while advisory communication stays with the CPA.
What is the ROI of hiring an EA for a CPA firm?
For a CPA billing at $200/hr who reclaims 6 admin hours per week, the recovered time is worth roughly $1,200 weekly; against a $1,500/month EA cost, the math resolves before the end of month one.
If you bill $150/hr or more and spend more than 5 hours a week on admin, the math already works. The only question is when. Book a 20-minute conversation. Bring your average admin hours and we will run the numbers with you.
