7 Best Executive Assistant Staffing Agencies in the US: Direct Hire vs Temp Payroll

Hiring an executive assistant through a staffing agency looks simple until your inbox floods and every résumé blurs. In May 2025, executive assistants earned a median $76,590, according to the U.S. Bureau of Labor Statistics, and six-figure offers are routine in the largest metros. Yet the bigger decision is employment model: direct hire, temp payroll, temp-to-hire, or a fractional W-2 subscription. Choose the wrong lane and you’ll waste weeks, and budget, on interviews that never stick. In this guide, we compare seven U.S. executive-assistant staffing agencies, each aligned to a specific model, so you can match need, timeline, and risk in one read.

Why your hiring model comes first

Cost, speed, and risk shift based on who employs the assistant. Decide that first; the agency choice comes second.

Direct hire. A recruiter introduces candidates, you pay a one-time fee (typically 20-30 percent of first-year salary), and the EA joins your payroll. Stability is high, but if the match fails after a 60- to 90-day guarantee, replacing the hire falls on you.

Temporary staffing. The agency stays the legal employer and bills an hourly rate about 30-50 percent above the EA’s pay rate. Choose this for maternity leave, medical coverage, or a head-count freeze.

Temp-to-hire. You trial the assistant for roughly three months, then move them to your payroll under a written fee schedule. The upfront premium buys insurance; walking away costs less than carrying a mismatched permanent hire for a year.

Fractional W-2 subscription. Providers such as Boldly sell 40-100 remote hours a month (plans start around $2,600). You avoid payroll admin, but unused hours expire, and a 30-day notice usually applies.

We suggest noting how long you need help, whether on-site presence matters, and how quickly coverage must start. With those answers, the seven executive-assistant staffing agencies that follow will map neatly to your scenario.

How we picked the seven agencies

We reviewed U.S. executive-assistant staffing agencies against eight factors: C-suite specialization, vetting depth, model clarity, reach, speed, pricing transparency, guarantee length, and reputation. We removed offshore marketplaces, job boards, and single-city boutiques, cut any provider whose only proof of quality was its own marketing, then mapped the strongest firms to real hiring scenarios (permanent search, urgent temp cover, fractional remote support) and named seven category winners instead of one generic best.

*“Quote required” means the firm customizes fees and does not publish a standard placement percentage or bill-rate markup online.

A blank cell is not a flaw; it simply shows that the model sits outside the agency’s core offer or isn’t documented publicly. Use the table to align each option with your timeline, budget, and risk tolerance.

C-Suite Assistants: best specialist for nationwide permanent EA searches

Need a full-time, high-trust partner for a CEO or founder? C-Suite Assistants is a contingency staffing agency that does one thing: permanent direct-hire search for executive assistants, chiefs of staff, and related senior support roles across the United States and Canada. Its recruiters work a proprietary database plus a LinkedIn executive assistant group of more than 100,000 members, review 50 to 75 candidates per role, and deliver a curated shortlist in about 3 to 4 weeks; urgent briefs have closed in 10 days.

Because the search is contingency, the firm invoices a placement fee, a percentage of first-year base salary quoted up front, only when you hire. If the hire does not work out for performance reasons inside 90 days, the team reruns the search at no extra cost.

Recruiters run structured interviews, a full work-history review, reference checks, and role-specific assessments, and weigh judgment, communication style, and cultural fit alongside skills. The firm says that vetting saves clients 15 to 20 hours of screening time per search.

Use nationwide executive assistant staffing when you want:

• Permanent, long-term support rather than a temp bench
• A senior, confidential, or remote-first role
• Contingency pricing plus a written replacement guarantee

Skip it if you need someone on payroll tomorrow or only for a short leave; a direct-hire specialist is excessive for a two-month gap.

Career Group Companies: best all-in-one staffing and payroll partner

When the hiring plan might shift mid-stream, Career Group Companies is the executive-assistant staffing agency that covers every lane: direct hire, temporary, temp-to-hire, and payroll-only. Its administrative desk staffs EAs across finance, creative and media, fashion, tech, and private households, then handles payroll taxes, unemployment insurance, workers’ compensation, and benefits administration under one bill rate.

Speed and flexibility. Its temp network is pre-screened and ready to step in immediately, and a temp-to-hire path lets you run a trial period on agency payroll before converting the EA to your own headcount; ask for the conversion schedule in writing before the assignment starts.

Why clients choose it

• One vendor for temp coverage today and permanent search tomorrow
• Industry-specific desks that understand finance, media, fashion, and tech culture
• In-house payrolling that removes multistate compliance work

Watch-outs

Career Group prices each engagement individually and does not publish standard mark-ups, so ask for the full breakdown (hourly bill rate, overtime multiplier, and conversion schedule) before you approve a requisition.

Beacon Hill: best enterprise executive-support partner

Enterprise HR teams juggle multisite headcount, compliance, and sudden VP promotions. Beacon Hill Associates meets that scale challenge. The executive-assistant staffing agency’s administrative division draws from a pool of about 743,000 pre-screened candidates, and the parent firm reported 2025 revenue of roughly $1.1 billion, giving it the capacity to supply contract, contract-to-hire, or retained search talent in hours.

Speed is documented. The administrative division publishes a same-day average time-to-fill for administrative roles, and one Beacon Hill case study notes more than 150 direct hires placed for a single Boston-based private equity client since 2004.

Because each branch runs its own desk, results vary. Interview the recruiter who will own your search and ask for branch-level fill time, 12-month retention, and temp-to-perm conversion metrics. When the local team is strong, you gain enterprise-grade compliance without losing boutique attention.

Choose Beacon Hill when you support multiple executives across several states or need both temp cover and permanent search under one master agreement. If you require only one assistant in a single office, a specialist boutique may feel more personal.

Robert Half: best for national scale and rapid contract coverage

When your calendar explodes, Robert Half is the executive-assistant staffing agency many enterprises already keep on speed dial. The company says its global database holds millions of administrative candidates, backed by more than 2 million contract and full-time placements, and local offices can present a short-listed EA contractor in as little as 48 hours.

Scale brings perks: Robert Half stays the EA’s legal employer, handling multistate payroll, overtime, and workers’-comp compliance, so finance and legal teams can sign off quickly. If your temp proves indispensable, your account manager can convert the contract to a direct placement under a written fee schedule, with no new vendor setup required.

The trade-off is intimacy. The firm staffs everything from data entry to CFO search, so results depend on the individual recruiter. Before you approve a requisition, ask for branch-level fill time, 12-month retention, and a detailed bill-rate breakdown.

Choose Robert Half when urgency outranks specialization, when headcount spans multiple states, or when you want one vendor for temps, conversions, and direct hires. If you prefer a boutique focused solely on executive support, keep shopping.

Tiger Recruitment: best for private-equity, family-office, and UHNW support

Ultra-high-net-worth principals need an assistant who can jump from board decks to jet manifests without a hiccup. Tiger Recruitment, a B-Corp executive-assistant staffing agency headquartered in London and anchored in New York, was built for that world. Its corporate and private divisions speak the language of deal teams, household staff, and encrypted calendars.

Clients receive a curated slate of three to six finalists, not an inbox of résumés, and Tiger reports that 73 percent of the job briefs it received last year came from repeat clients. That track record signals the confidentiality private-equity and family-office leaders expect.

Tiger also places temporary and contract assistants from a standby pool, and you can convert a temp to a permanent offer if the fit is right. Vetting is multi-stage: thorough interviews, skills assessments, reference checks, and background screenings before you ever take a meeting.

Choose Tiger when business and personal spheres blur, discretion is non-negotiable, and the budget stretches into six figures plus bonus. Skip it if you need a large local temp bench outside New York or prefer published fee tables; everything here is bespoke, much like the service it sells.

Scion Staffing: best for interim and leave coverage

Parental leave, medical gaps, or product sprints can leave you short-handed. When you need an executive-assistant staffing agency that moves quickly, Scion Staffing delivers. Its nationwide bench of administrative talent tops 16 million vetted candidates, and recruiters can often match and onboard qualified EAs within 24 to 48 hours.

Because the assistant remains on Scion’s W-2, you avoid payroll taxes, workers’ comp, and state-by-state compliance. Engagement length is set by you. Ask for a written conversion schedule up front so you know what hiring the temp outright will cost, and Scion’s executive-search team can launch a parallel permanent search.

Call Scion when you face a sudden vacancy, planned leave, or fixed-duration project. If the role is clearly permanent from day one, a direct-hire specialist may cost less than paying a temp markup.

Boldly: best fractional remote W-2 support

When you need a seasoned executive-assistant staffing agency for only 10-25 hours a week, Boldly’s subscription model is the clear choice. You buy monthly blocks of 40, 60, 80, or 100 remote hours; the 40-hour plan costs about $2,600, or roughly $65 per scheduled hour. Boldly is the EA’s W-2 employer, covering payroll taxes, benefits, and compliance.

Assistants bring 10 to 15 years of experience and are W-2 employees of Boldly, not contractors. You interview your proposed EA on video before launch, and a trained backup steps in during vacations or spikes.

Scope suits a fractional relationship: inbox triage, calendar management, travel, and light project coordination. No on-site errands. Unused hours expire, yet you can scale plans up or down with 30 days’ notice, avoiding severance or unemployment risk.

Choose Boldly if you’re a founder, solopreneur, or remote exec who needs high-caliber support without adding headcount. If you require on-site help, true 24/7 coverage, or more than 100 hours monthly, a full-time hire is likely cheaper.

Direct hire vs. temp payroll: cost, control, and risk

Hiring model shapes every downstream decision. From cash outlay to management burden, let’s place the two primary options side by side.

Direct hire. The assistant joins your payroll. You pay a one-time recruiter fee, typically 20-30 percent of first-year salary, then cover wages, taxes, and benefits yourself.

Temp payroll. The staffing agency is the legal employer. You receive an hourly invoice that folds in the assistant’s pay plus a 30-50 percent markup to cover statutory burden, benefits, recruiting overhead, and agency profit.

90-day cash comparison*

Model	Paycheck issuer	Typical fee model	First 90-day cash outlay
Direct hire	Client	20-30 % placement fee	$45k-$55k on a $100k salary (one quarter of salary + fee)
Temp payroll	Agency	30-50 % markup	$32.5k-$37.5k (40 hr/week, no OT)

*Employer payroll taxes and benefits on the direct-hire side are excluded; those costs sit inside the temp markup.

At roughly the nine-month mark, a 40 percent temp markup equals a 30 percent placement fee. Add your own benefits load and the crossover arrives sooner. Short engagements (under nine months) tend to favor temp payroll; multiyear roles favor direct hire.

Next we’ll compare control and commitment: who sets goals, how fast you can swap talent, and which guarantees truly protect you.

Control, commitment, and guarantees

Cost aside, control (who sets goals, approves raises, and handles discipline) differs sharply by hiring model.

• Direct hire. The EA is your employee, so performance management, bonuses, and terminations follow your HR policies. Recruiter guarantees protect only the agency’s fee: most promise a free replacement (not a refund) for 60-90 days.
• Temp payroll. The assistant stays on the staffing agency’s org chart. You direct day-to-day work, but pay, benefits, and corrective action flow through the vendor. Need a swap? Call the account manager; replacements are usually included in the markup.

Commitment length flips, too. Permanent hires lock in headcount and unemployment risk. Temps work at will: extend, shorten, or end the assignment as business needs shift, but expect a conversion fee if you hire the temp, and some agencies require a minimum number of agency hours before you can convert or walk away penalty-free, so ask for the threshold in writing.

Ask every executive-assistant staffing agency two questions:

1. What triggers the guarantee? Resignation only, termination for cause, or any separation?
2. What does “replacement” include? Another search at no fee, a prorated refund, or a credit toward future work?

Clear answers up front prevent surprises the week before your board meeting.

Buyer-persona shortcuts: who should hire which model?

All seven executive-assistant staffing agencies can land a great EA, yet each shines for a different buyer. Use this cheat sheet to jump straight to the model that fits your reality.

Enterprise C-suite managing multistate teams
Beacon Hill or Robert Half: national payroll reach, compliance muscle, and round-the-clock temp benches.

Founder ready for a full-time right hand
C-Suite Assistants: contingency fee, 90-day replacement, and a focus on senior support roles.

Solopreneur drowning in email
Boldly: 40-hour fractional plan at $2,600, cancel or scale with 30 days’ notice.

Private-equity partner or family-office principal
Tiger Recruitment: curated three-to-six-candidate shortlist, 73 % of briefs from repeat clients, discretion guaranteed.

HR leader covering parental leave
Scion Staffing: vetted temp EAs in 24 to 48 hours; get the conversion schedule in writing.

Company that sourced its own EA but lacks headcount
Career Group: payroll-only service until budget clears, then convert under a conversion schedule you get in writing.

Match your situation, pencil in the budget, and the shortlist almost writes itself.

Why even a good agency placement can fail

An executive-assistant staffing agency can deliver a five-star EA, yet the role still collapses if fundamentals are off.

• Compensation. The 2025 State of the Profession report by the American Society of Administrative Professionals shows average pay climbed to $69,643, with 44 percent of administrative professionals now earning over $70,000. Under-market wages invite churn.
• Scope creep. Add chief-of-staff projects to expense reports without raising salary or title and burnout follows fast.
• Authority gaps. Assistants who can’t approve $200 flights or view the exec’s calendar spend half the week waiting for sign-offs instead of solving problems.
• Executive chemistry. Leaders who refuse to delegate email or share a calendar undercut the EA’s value on day one.
• Onboarding misses. Onboarding research widely cited across the HR industry puts up to 20 percent of employee turnover inside the first 45 days. Skipping a documented 30-60-90 plan raises the odds of an early exit.

Audit the role before blaming the recruiter: define scope, pay at market, grant real decision rights, and schedule weekly check-ins. With those basics in place, any of the seven agencies in this guide can keep you staffed for years, not months.

Your first 90 days with a new EA

Day one sets the tone, but retention is won over quarters. Treat this timeline as a living checklist and adjust it to your industry rhythm.

Week 1: access and alignment

• Grant full calendar and inbox visibility, security credentials, and a stakeholder map.
• Walk through travel preferences, meeting priorities, escalation rules, and confidentiality boundaries.

Weeks 2-4: workflow calibration

• Ask the EA to audit recurring meetings, flag low-value time sinks, and propose fixes.
• Document standard operating procedures; Loom videos or Google Docs keep know-how out of your head and into shared systems.

Days 31-60: ownership shift

• Hand off one recurring deliverable (for example, a leadership agenda or investor follow-ups).
• Hold a midpoint review to surface friction early and celebrate quick wins such as reclaimed hours.

Days 61-90: strategic expansion

• Add project-management or light chief-of-staff work if the core is solid.
• Compare output against the scorecard drafted pre-hire. If you used temp-to-hire, start conversion paperwork now to avoid surprise fees.

Throughout the 90 days, run a 10-minute daily stand-up and a 30-minute weekly retro. These short, rhythmic feedback loops prevent small miscommunications from hardening into habits and can turn a good hire into a great executive partnership.

FAQ: quick answers to common agency questions

How much do executive-assistant recruiters charge?
LegalClarity’s 2026 guide puts direct placement fees at 15 to 25 percent of first-year salary and temporary staffing markups at roughly 25 to 50 percent of the EA’s pay rate; budget toward the top of each range for senior, confidential roles.

What’s the difference between a staffing agency and a recruitment agency?
Recruitment agencies introduce candidates you will employ. Staffing agencies remain the legal employer, pay the EA, and invoice you hourly. Some firms such as Career Group, Beacon Hill, and Robert Half provide both services.

Who signs the paychecks for a temporary EA?
The staffing agency, which also covers payroll taxes, workers’ comp, and unemployment insurance. You pay only the bill rate.

How long does it take to hire through an agency?
Urgent temp coverage can start in 24-72 hours; boutique direct-hire searches typically close in 3-6 weeks, depending on salary and location.

What happens if the placement fails?
Direct-hire guarantees usually offer a free replacement for 60-90 days. Temp agencies swap the worker at no extra cost because the EA is their employee. Get the terms in writing before you sign.

Can agencies find remote executive assistants?
Yes. Every executive-assistant staffing agency in this guide sources remote talent, and Boldly is 100 percent remote by design. Confirm time-zone overlap and security protocols before signing.

Is a specialized EA recruiter better than a general staffing firm?
For confidential, high-profile roles, niche recruiters such as C-Suite Assistants or Tiger Recruitment add value through deeper vetting. For large enterprises needing volume and speed, generalists like Robert Half often win on capacity and compliance.

Your next steps

We recommend working through these ten moves in order.

1. Choose a hiring model today.
2. Under six months: temp payroll
3. Six to twelve months with uncertainty: temp-to-hire
4. Indefinite: direct hire, or fractional if hours stay part-time
5. Set market-rate compensation.
   Pull current BLS data or an agency salary guide before you call any executive-assistant staffing agency.
6. Draft a one-page scorecard.
   Capture duties, success metrics, decision rights, and required tools; share it with every recruiter.
7. Shortlist two or three agencies (max).
   Pair one specialist with one scaled generalist; adding more shops creates candidate-ownership conflicts.
8. Request written proposals.
   Ask for fee or markup, replacement terms, conversion schedule, and overtime multipliers in black and white.
9. Interview the recruiter, not just the brand.
   Probe recent EA placements in your industry and city, 12-month retention, and average time to offer.
10. Use live test work.
    A 30-minute calendar or travel exercise reveals judgment faster than scripted interview questions.
11. Prepare a 30-60-90 onboarding plan.
    Share it during final interviews so candidates see you are invested in their success.
12. Schedule weekly check-ins for the first quarter.
    Frequent feedback beats one big review at the guarantee deadline.
13. Mark the guarantee expiry on your calendar.
    If performance wobbles at day 80, you still have time to act before coverage ends.

Follow this playbook, and whichever agency you choose, boutique or large, will have what it needs to deliver an EA who frees your time and stays long after the guarantee window closes.

Wrapping up

The right executive-assistant staffing agency is the one whose employment model, speed, and risk profile fit your reality. You now know how direct hire, temp payroll, temp-to-hire, and fractional subscription compare, and which agency shines in each model.

With a clear budget, a one-page scorecard, and the ten steps above, you can trim weeks from the search, protect your downside, and secure an assistant who frees more hours than you thought possible.

We invite you to engage your shortlist and schedule the first recruiter interviews. Your calendar, along with your company, will thank you.
