An administrative assistant supports specific people by managing their schedules, communications, and paperwork. An office manager runs the office itself, supervising staff and owning facilities, vendors, budgets, and policy. Assistants are usually individual contributors; office managers are usually people managers with budget authority and higher pay.

Frontline Source Group has placed administrative and office professionals since 2004 and has completed 5,619 plus placements from 32 plus offices nationwide, with a 98.94% executive placement retention rate and a 5.0-star Trustpilot rating across 683 plus verified reviews. Forbes has named the firm a Best Professional Recruiting Firm for 9 consecutive years (2018 to 2026, #158 in 2026) and a Best Executive Recruiting Firm (#148 in 2026). It is also a 9-time ClearlyRated Best of Staffing winner for both Client and Talent satisfaction, a ClearlyRated Diamond Award recipient, an Inc. 5000 honoree, an Expertise.com Best Staffing Agency, and a member of the American Staffing Association (ASA). Qualifying direct hires are backed by the 5-Year Placement Warranty, 20 times longer than the 90-day guarantee common in the industry.

Both roles matter to a well-run office, but they sit at different levels and call for different skills. Job seekers need to understand the day-to-day work and where each path leads. Employers need to know which role they actually need, because giving a job the wrong title is a common and costly mistake in office staffing.

What does an administrative assistant actually do day to day?

Administrative assistants keep the daily work moving for the people they support. Their responsibilities cluster in five areas:

• Calendar and schedule management. Coordinating meetings, scheduling appointments, managing recurring blocks, and resolving calendar conflicts for executives or team members they support. Even small calendar mistakes can ripple through the workflow.
• Communication management. Answering phone calls, screening and triaging emails, drafting correspondence, and acting as a liaison between departments. Strong administrative assistants filter what reaches their executive and surface what matters.
• Document and records management. Preparing reports, presentations, contracts, and other documents. Maintaining filing systems (digital and physical), version control, and organized archives that anyone on the team can navigate.
• Travel and event coordination. Booking flights, hotels, ground transportation, conference registrations, and offsite events. Building itineraries that account for time zones, traveler preferences, and back-up plans for delays.
• Project and task support. Tracking deadlines, following up on action items, and supporting the team through one-off projects ranging from board meeting prep to office moves.

What does an office manager actually do day to day?

Office managers run the operation of the office itself rather than supporting individual executives. Their work cuts across people, operations, and facilities:

• Staff supervision and people management. Direct supervision of administrative staff, receptionists, and other office support roles. Performance reviews, coaching, hiring, and managing team workload distribution.
• Facilities and vendor management. Overseeing the physical workspace including cleaning services, IT vendors, security systems, snack and coffee programs, mail and shipping, conference room scheduling, and office maintenance.
• Budget responsibility. Managing the office operating budget, processing expense reports, approving purchases within authority, negotiating with vendors, and reporting on spend against budget to leadership.
• Policy compliance and process design. Ensuring office operations align with company policies, employment regulations, safety requirements, and any industry-specific compliance obligations. Designing and documenting the processes that other administrative staff follow.
• Cross-functional coordination. Working with HR on onboarding logistics, with IT on equipment and access, with finance on procurement, and with leadership on company-wide initiatives that touch the office.
• Office culture and employee experience. Planning company events, employee recognition programs, internal communications, and the small daily touches that make the office feel like a place people want to be.

What skills does an administrative assistant need?

• Exceptional organization. Juggling multiple calendars, projects, and priorities without dropping balls. Strong administrative assistants have a system, whether digital, paper, or hybrid, that they maintain religiously.
• Clear and professional communication. Written and verbal communication at every level of the organization, from the receptionist to the CEO, with appropriate tone and confidentiality for each context.
• Technical proficiency with office software. Word processing (Microsoft Word, Google Docs), spreadsheets (Excel, Google Sheets), presentation software (PowerPoint, Keynote, Google Slides), email and calendar systems (Outlook, Google Workspace), and increasingly, project management tools like Asana, Monday, or Trello.
• Attention to detail. Catching the small errors (wrong date, wrong attendee, missing attachment) before they cause downstream problems.
• Discretion and confidentiality. Administrative assistants often have visibility into sensitive personnel, financial, and strategic matters. Protecting that information is foundational to the role.
• Time management and prioritization. Working under shifting priorities, managing competing requests, and protecting the executive's time from low-value interruptions.
• Adaptability and problem-solving. Handling whatever the day brings, from a last-minute travel change to a system outage to an unexpected visitor.

What skills does an office manager need?

• People leadership. Direct management of staff requires the ability to lead, motivate, coach, give feedback, and handle performance issues fairly and decisively.
• Operational planning and execution. Managing multiple workstreams simultaneously, prioritizing across competing demands, and ensuring nothing important gets dropped as the office scales.
• Budget and financial literacy. Reading a budget, tracking spend, understanding cost drivers, and making informed trade-off decisions about where to invest the office's discretionary spend.
• Vendor negotiation and relationship management. Office managers spend significant time interacting with vendors (cleaning, IT, security, food service, facilities) and need to negotiate favorable terms and hold vendors accountable.
• Interpersonal and influence skills. Office managers work across every function in the company. The ability to build relationships, influence without direct authority, and resolve conflicts is essential.
• Policy and compliance awareness. Understanding employment law basics, safety regulations, document retention requirements, and any industry-specific compliance obligations.
• Project management. Office moves, technology rollouts, policy implementations, and event planning all require structured project management skills.

What education and qualifications do these roles require?

Expectations differ between the two roles, though both have flexible paths depending on the employer and industry.

What education does an administrative assistant need?

A high school diploma or equivalent is often the minimum. Many employers prefer some college, such as an associate's degree or certificate in office administration or business support. Helpful credentials include the Certified Administrative Professional (CAP) designation from the International Association of Administrative Professionals (IAAP) and Microsoft Office Specialist certifications.

What education does an office manager need?

A bachelor's degree in business administration, management, communications, or a related field is often preferred, especially as the office grows. Many employers still promote experienced administrative assistants without the degree when their track record shows the right capability. Senior office manager roles at larger organizations may prefer an MBA. Useful credentials include the Certified Manager (CM) designation from the Institute of Certified Professional Managers and project management credentials such as PMP or CAPM.

How much do administrative assistants and office managers make?

Office managers usually earn more, because the role adds people management, budget authority, and vendor responsibility. Pay for both roles varies widely by industry, location, company size, and experience.

How much does an administrative assistant make?

According to the Bureau of Labor Statistics, the median annual wage for secretaries and administrative assistants was $47,460 in May 2024, and the occupation held about 3.5 million jobs. BLS projects little or no change in overall employment from 2024 to 2034. Executive assistants who support senior leaders typically earn more than the overall median.

How much does an office manager make?

BLS does not track "office manager" as its own occupation. Most office managers fall under first-line supervisors of office and administrative support workers, whose national median was $66,140 in May 2024. Office managers at larger companies, or with facilities and budget responsibility, often earn well above that.

What are the career growth paths for administrative assistants?

• Executive assistant or chief of staff. The most common upward path. Senior executive assistants supporting C-level executives or chiefs of staff supporting CEOs and founders often earn at or above some office manager roles, with significantly more strategic exposure.
• Office manager. Many office managers started as administrative assistants and earned the management opportunity through proven operational capability and informal leadership.
• Project coordinator or project manager. Administrative assistants who develop project management skills (often working alongside executives on company initiatives) can transition into formal project roles.
• Specialized administrative roles. Legal administrative assistants, medical administrative assistants, and executive assistants for specific functions (finance, legal, technology) can build careers around domain expertise.
• HR or operations specialist tracks. Administrative assistants who develop strong people skills sometimes transition into HR coordinator, recruiter, or operations analyst roles.
• Industry-specific advancement. Administrative experience in a specific industry (healthcare, legal, finance, technology) often opens doors to industry-specific operational roles.

What are the career growth paths for office managers?

• Operations manager or director of operations. Office managers who excel at process design and cross-functional coordination often advance into broader operations roles overseeing multiple offices or operational functions.
• Facilities manager or real estate manager. For office managers who develop deep facilities expertise, advancement into corporate facilities or real estate roles is a strong path, especially at companies with multiple locations.
• Human resources manager or HR business partner. Many office managers transition into HR through their people-management experience, often pursuing SHRM-CP or HRCI certification to formalize the move.
• Administrative services manager or office of the COO. Office managers at larger companies sometimes advance into corporate administrative services oversight or chief of staff to the COO type roles.
• Office manager at a larger organization. Moving from office manager at a 25-person company to office manager at a 250-person company represents significant scope, complexity, and compensation growth.
• Business operations or program management. Office managers with strong project skills can move into business operations roles supporting specific functions or programs.

How do you choose between an administrative assistant role and an office manager role for your career?

The decision comes down to a few questions about your strengths, preferences, and career trajectory:

• Do you prefer supporting individuals or running operations? Administrative assistants build deep working relationships with the people they support. Office managers work across the whole office and prioritize systems and processes over relationships with any one executive.
• Do you want to manage people? Office managers manage staff. Administrative assistants generally do not. If people management is a goal, the office manager track is the direct path.
• Do you have or want budget responsibility? Office managers control discretionary spending and negotiate vendor contracts. Administrative assistants typically work within a budget rather than managing one.
• Where do you want to be in five to ten years? If the answer is "chief of staff" or "executive assistant to the CEO," the administrative assistant track is your path. If the answer is "director of operations" or "VP of operations," office manager is the better foundation.
• What industries interest you? Both roles exist across virtually every industry, but the day-to-day differs. Healthcare administrative assistants do meaningfully different work than technology executive assistants. Manufacturing office managers handle different facilities concerns than law firm office managers.

Talk with people in both roles before you commit. Pursue education and certifications that fit the path you choose, and build your skills on purpose rather than waiting for the right opening to appear.

How do employers decide which role to hire for?

Giving a role the wrong title is a common and expensive mistake. A few practical guidelines help.

When does a company need an administrative assistant?

When the role mainly supports specific executives or teams, with no staff to supervise and no budget to own. Smaller offices often do best with a strong administrative assistant who can flex into some operational work, and companies with several senior executives usually need dedicated assistants rather than asking an office manager to do both jobs.

When does a company need an office manager?

When the role supervises other staff, owns a budget and approves spending, or covers vendor management, leases, security, IT coordination, and facilities planning. Growing offices usually reach a point where a dedicated office manager is needed. Pay the role to match its scope. When the title and pay say administrative assistant but the job is really office manager, strong candidates turn it down or leave soon after starting.
