Hire Part-Time Executive Assistant for Consulting Firm

Part-time executive assistant arrangements are a strong fit for many consulting firms: established enough to need professional support but not yet requiring full-time EA coverage. Getting the part-time model right requires understanding what “part-time” means in different service structures, how to define the scope, and how to make a limited-hours arrangement genuinely effective.

What “Part-Time” Means in Different EA Models

The concept of part-time EA support is structured differently depending on the service model.

Part-Time Through a Managed Virtual Platform

In this model, you subscribe to a defined number of hours per week, typically 10 to 25 hours, through a managed EA service. The EA is dedicated to your firm during those hours and operates as a professional partner within the defined capacity.

This is the most common part-time model for consulting firms. The EA works part-time for you specifically, with full access to your systems and a genuine professional relationship.

Part-Time Direct Employment

Hiring a part-time EA as a W-2 employee of the consulting firm, typically at 20 to 30 hours per week. The EA is exclusively yours during their working hours, benefits are provided on a prorated basis (depending on hours and applicable law), and the employment relationship carries all the standard obligations of direct employment.

This model produces the deepest institutional integration but carries the most employment overhead.

Part-Time Independent Contractor

Engaging a part-time EA as a 1099 independent contractor. The EA works part-time for your firm under a contract arrangement, without the employment obligations of a W-2 hire.

Important: The appropriateness of contractor classification depends on the facts of the arrangement. An EA who works exclusively for one firm, follows the firm’s direction and schedule, and functions as an employee in all but title is likely misclassified as a contractor. Consult legal counsel before structuring a part-time exclusive arrangement as a contractor engagement.

Shared or Pool-Based Services

Some EA services offer lower-cost shared arrangements where the EA serves multiple clients simultaneously. These are sometimes described as “part-time” because the EA works part-time for each client.

For consulting firms, shared arrangements are typically not adequate for CEO-level support. The lack of dedicated context and relationship depth makes shared arrangements appropriate only for task-based, low-complexity needs.

How Many Hours Does a Consulting Firm CEO Actually Need Part-Time?

The right hours level depends on your actual administrative load. Common part-time ranges:

10 to 15 hours per week: Appropriate for solo consultants or very early-stage firms with primarily scheduling, basic email management, and occasional travel coordination needs.

15 to 20 hours per week: The most common range for consulting partners at boutique firms. Covers full calendar management, email oversight, travel coordination, and BD administration for a CEO managing 3 to 5 active client relationships.

20 to 30 hours per week: A heavier part-time arrangement approaching the transition point to full-time. Appropriate for CEOs with significant support needs who are not yet at full-time volume.

To calibrate: one week of honest time tracking, categorizing tasks as delegatable or not, gives a reliable hours estimate. Do not estimate based on intuition; estimate based on data.

What a Part-Time Consulting EA Can Handle

A well-selected part-time EA supporting a consulting CEO can handle:

Full calendar management: Complete ownership of the CEO’s calendar, including proactive protection of strategic time blocks, coordination across multiple time zones, and management of complex scheduling conflicts.

Email management: Triage, response drafting, flagging priority items, managing inbox to zero. At 15 or more hours per week, an EA can manage email substantially, not just occasionally check it.

Travel coordination: Booking, itineraries, ground transportation, and expense processing for typical consulting travel schedules.

Business development administration: CRM updates, prospect follow-up tracking, meeting preparation for BD conversations, and coordination of proposal logistics.

Meeting preparation: Briefing documents for client and internal meetings, agenda preparation, and follow-up action tracking.

Vendor and operational coordination: Managing the consulting firm’s operational vendors, service providers, and administrative relationships.

What a part-time EA typically cannot handle in a limited-hours arrangement:

Full communication ownership: A 10-hour/week EA does not have the time to truly own the CEO’s communication. Triage and prioritization are feasible; full email management at the same level as a full-time EA is not.

Real-time availability throughout the business day: A 10 to 15 hour/week EA is not available at every moment. Establish clear working hours and response time expectations that reflect the actual arrangement.

Sourcing a Part-Time Consulting EA

Managed Virtual Platform (Recommended Starting Point)

Platforms that offer part-time subscriptions at the hours you need:

Prialto, Boldly, and Belay offer various hours tiers starting at part-time levels
Near-shore platforms (Latin America) offer part-time arrangements at lower cost points
Confirm that the arrangement is dedicated (not shared) at the part-time hours level

Direct Sourcing for Part-Time Employees

If hiring a part-time employee directly:

Post on LinkedIn, Indeed, and EA-specific professional networks
Specify in the job posting that the role is part-time and describe the hours range
Look for candidates whose prior experience includes supporting senior executives at professional services firms, even if those roles were full-time
Experienced EAs who want part-time flexibility (due to family commitments, other professional projects, or preference) are often excellent candidates for structured part-time arrangements

According to the Bureau of Labor Statistics, part-time employment among executive administrative assistants is common, reflecting the range of organizational sizes and support needs in the professional services sector.

Making Part-Time EA Support Work

Concentrate the Hours Strategically

Define which task categories get the EA’s time first. Calendar management typically delivers the highest leverage; email management is close behind. Make sure the limited hours are allocated to the highest-leverage tasks before lower-priority items.

Establish Clear Working Hours

For a part-time arrangement, define when the EA is available and communicate this to colleagues and yourself. A 20-hour/week EA who works Monday through Thursday mornings is not available for urgent requests Friday afternoon. Align expectations with the reality of the arrangement.

Build Context Efficiently

With fewer hours available, the EA must build context about your firm and your clients more efficiently. Invest in a thorough onboarding briefing at the outset. Create written documentation of key clients, scheduling conventions, and communication preferences that the EA can reference without needing to ask questions.

Avoid Scope Creep

Part-time arrangements are particularly vulnerable to scope creep: gradually adding tasks until the EA is expected to accomplish full-time work in part-time hours. Monitor the task load relative to available hours, and either adjust hours upward or prioritize ruthlessly if the load exceeds capacity.

The Cost of Part-Time EA Support

Managed virtual platform (part-time, 15 to 20 hours/week):

US-based: $1,500 to $3,500 per month ($18,000 to $42,000 annually)
Near-shore: $700 to $1,800 per month ($8,400 to $21,600 annually)

Part-time direct employment (US-based, 20 hours/week):

All-in annual cost: $45,000 to $75,000

Independent contractor (US-based, 15 hours/week):

Hourly rate: $30 to $60
Annual cost: $23,400 to $46,800

Conclusion

Hiring a part-time executive assistant for a consulting firm is a viable and often optimal structure for firms at early to mid-growth stages. The right model (managed platform for convenience, direct employment for maximum integration, contractor for flexibility) depends on the consulting firm’s size, stage, and administrative requirements.

Regardless of model, the keys to effective part-time EA support are: allocating hours to the highest-leverage tasks, establishing clear availability expectations, investing in efficient context transfer, and resisting scope creep. The consulting CEO who structures part-time EA support thoughtfully will find that even 15 to 20 hours per week of professional EA engagement significantly transforms their operational capacity.
