Office Administrator vs. Office Manager: What’s the difference?

While it’s easy to assume an Office Manager (OM) and an Office Administrator (OA) do the same thing, the two positions have subtle differences that could add up over the course of one career.

We’ll take an in-depth look at the two positions below, but here’s your quick take on the key differences between an OA and OM. (Note: You’ll likely find exceptions to these statements, depending on the particular company and role in question.)

  • Office Managers focus on “people” processes. They keep offices running happily and efficiently by providing employees with tools, resources, policies, and initiatives that enable good work.
  • Office Administrators focus on “technical” processes. They keep offices running strategically and efficiently by implementing and improving technology solutions, processes, and schedules that keep work flowing – we recommend using a software like

A Typical Workday


A Day in the Life of an Office Manager

A day in the life of an Office Manager will look different at nearly every company, but the bulk of any OM’s day will likely involve managing office processes to help work run as efficiently as possible and keep employees happy and productive. An OM might have to take a high-profile client on an office tour one day and then lead a new-employee orientation training the next day.

Excitement, variation, and most importantly, people make OM roles rewarding for high-energy individuals. In an interview with Artisan Creative, one Office Manager says, “I think the most rewarding part of my job is completing tasks that I know will make someone else’s day just a little bit easier.”

Here’s an example of an OM’s to-do list for one day. (This could be everything an office manager plans to do, but naturally, every single day will come with a variety of surprises.)

  • Check kitchen and coffee station supplies. Place monthly coffee and snack order; schedule delivery for Friday afternoon.
  • Meet with office admin team to develop weekly priorities and benchmarks.
  • Run and export weekly payroll report.
  • Visit new hires (3 this week) to deliver key fobs and review security procedures.
  • Call vendor to schedule installation of the new audiovisual system in the main conference room.
  • Get CEO’s sign-off on the final itinerary for upcoming company retreat.
  • Send email invitation for company retreat.
  • Meet and greet new client before 2PM meeting with Marketing team.
  • Log newly-received invoices.
  • Check in on 90-day hires to make sure everything is going smoothly.
  • Have Controller sign next month’s budget.
  • Research and price office-friendly plants for new wellness initiative. 



A Day in the Life of an Office Administrator

Office Administrators take on different tasks every day, but nearly everything OAs do will require an eye for efficiency and an intense attention to detail. Tasks, like booking international travel and evaluating potential IT purchases, have little in common on the surface, but both items require someone who listens carefully, asks the right questions, thinks strategically, and makes decisions independently. A day in the life of an Office Administrator involves plenty of mental exercise. 

Here’s an example of an OA’s to-do list for one day. Just like OMs, OAs field many last-minute requests in any given day.

  • Spend one hour on the proposal for a new inventory tracking system
  • Have demo call with potential new IT security vendor; draft brief to present to Chief Information Office (CIO).
  • Book flights and transportation for all executives (5) traveling to Canada for the annual industry conference.
  • Go through leadership team’s latest meeting requests, schedule meetings, and update and sync calendars.
  • Respond to all emails in the office account. (Spend extra 30 minutes on this today to catch up.)
  • Process invoices received last week.
  • Process all reimbursement requests in queue.
  • Coordinate client airport pickup and dinner reservations for next week’s summit.
  • Reach out to list of applicants from Human Resources to schedule phone interviews.
  • Clean out supply closet in conference room 2.
  • Send email about new parking procedures effective next month.

Career Paths  


Both Office Managers and Office Administrators have bright career paths, filled with unlimited potential. In just a few years, OMs and OAs can learn more about the ins and outs of running businesses than many employees working in specialized fields will gain over several years. People in these positions learn to think on their feet, and they also gain experience solving mission-critical problems without assistance from bosses or upper management. Furthermore, these roles get to know everyone across the company. This means they can learn how many jobs across the company work, develop outstanding intrapersonal skills, and do all the networking they need to switch careers within the company.

In addition to positioning themselves for both upward and horizontal mobility, OMs and OAs often pick up the complete skill set required to make successful entrepreneurs or operational consultants.



Office Manager Career Path

Mastering the well-rounded position of Office Manager can open up many doors and many career paths. OMs have the chance to grow into high-level managers, especially if they develop a knack for problem-solving and long-term strategic planning. They can also specialize in particular aspects of the role, going into HR positions, accounting roles, company training positions, and more.

According to the Princeton Review,

“The future of Office Managers looks bright. Many economists predict that the economy will continue to grow and provide more office managing job opportunities over the next six years.”

Some OMs master the basics of their roles in small firms and then grow into new OM roles at larger companies. OMs who move to larger companies will likely perform the same basic functions, but they often take on more responsibilities. These shifts help OMs expand their roles as they expand their skills.


Office Administrator Career Path

As Office Administrator jobs provide plenty of challenges and versatility, OAs can carve fulfilling careers from job-specific tasks and skills of deepest interest. For example, an OA who has found stride in office event and meeting planning can leverage that experience to land a full-time event planning gig. An OA who has developed a close working relationship with one specific executive might move into the role of high-level executive assistant. An OA who has developed or worked on several employee wellness programs might end up as the company’s Chief Wellness/Happiness Officer or in some cases a Chief of Staff.

In short, the career advancement possibilities for a motivated and ambitious Office Administrator have few limits. OAs with particular career goals in mind should be sure to pursue projects and responsibilities aligned with those goals to build stellar resumes.

Questions Office Managers and Office Administrators Field in a Day

Job descriptions provide a wonderful glimpse of core responsibilities, the bullet points a person in the position will face during annual reviews and other performance check-ins.  However, job descriptions don’t give applicants or new hires an idea of the kinds of questions and one-off requests they’ll likely face in any given day. No one can control this aspect of the job, but OMs and OAs who prepare for anything and everything will experience less on-the-job stress.
