Understanding service tiers in the EA market helps consulting executives select and set expectations accurately. Service tiers are the structured levels at which EA companies offer their services, each with different pricing, capabilities, and appropriate use cases. Selecting the wrong tier, either too basic or unnecessarily premium, results in either unmet needs or wasted investment.
How Service Tiers Are Constructed
EA service tiers in the consulting market are typically built around combinations of:
- Hours of support: How many hours per week or month the EA works on your behalf
- Dedicated vs. shared model: Whether you have your own named EA or share from a pool
- Quality level of the EA: Entry-level, professional, or senior
- Scope of capabilities: Which task categories are included
- Response time guarantees: How quickly urgent requests are addressed
- Management support: How much oversight and account management the service provides
- Backup coverage: What happens when your primary EA is unavailable
Understanding how each of these variables is structured in any specific tier is the key to comparing tiers accurately.
Tier 1: Essential or Starter
Target client: Independent consultants, early-stage advisory practices, executives new to EA support.
Typical hours: 5 to 10 hours per week (20 to 45 hours per month)
EA model: Dedicated or semi-dedicated EA at this tier; usually a professional but not necessarily senior-level
Capabilities typically included:
- Basic calendar management
- Email triage
- Simple scheduling coordination
- Basic travel research and booking
- Routine document management
Response time: Next business day for most requests; same-day for urgent items
Monthly pricing: $800 to $2,500 depending on provider quality and geography
What it’s good for: Establishing the basics of EA support, freeing up the most obvious administrative time, and building delegation habits before expanding to a fuller arrangement.
Consulting use case: A newly independent consultant who needs help managing their calendar and client email follow-up without the overhead of a larger engagement.
Tier 2: Professional or Standard
Target client: Managing partners at boutique consulting firms, consulting CEOs with moderate-to-significant support needs, executives who have confirmed the value of EA support and want to expand scope.

Consulting use case: A managing partner at a 15-person boutique consulting firm who needs comprehensive calendar management, full email oversight, regular travel coordination, and BD administration support.
Tier 3: Executive or Premium

What it’s good for: Consulting CEOs who need full operational coverage and want an EA who functions as a genuine operational partner rather than a task executor.

Consulting use case: A global managing partner at a major strategy consulting firm overseeing twelve senior partners, managing relationships with Fortune 100 clients, and leading public-facing thought leadership in the firm’s industry.
Choosing Your Tier: Practical Guidance
Start with an Honest Assessment of Hours Needed
The most important variable in tier selection is hours. Conduct a time audit to determine how many hours of administrative work you currently handle that could be delegated. Match the tier to your actual volume rather than to aspiration or budget.
Don’t Under-Tier on Quality
Within any hours-based tier, there is a quality dimension. Choosing the lowest-priced option within your hours range often means accepting lower quality. For consulting environments where quality matters in every output, investing in the right quality level within your tier is as important as choosing the right tier.
Build in Room to Grow
Select a tier where your current needs fit comfortably and there is room to grow into the upper end as your firm scales. Constantly pushing against your tier’s limits creates service degradation; having headroom in the tier allows for better quality as needs evolve within the same tier.
See EA roles in consulting for capabilities to expect at each tier.
For pricing across all tiers, see consulting EA pricing guide.
According to McKinsey, matching support investment to leadership complexity produces the strongest performance outcomes. Under-investing in support for high-complexity leadership roles is a consistent organizational mistake.
