How to put Office Manager duties on your resume
Convert routine duties into quantified achievements by attaching numbers and savings: the size of the office you supported, the budget you managed, the percentage you cut supply or processing costs, and how many vendors, events, or new hires you handled. "Managed office supplies" is forgettable; "Reduced supply costs by 18% through vendor negotiation" gets attention. Lead with the result, then the action.
Tailor each bullet to the posting. If the role leans operations and budgets, foreground expense tracking, vendor contracts, and process improvement; if it leans executive support, highlight calendar management, travel coordination, and confidentiality. Mirror the exact keywords from the listing (such as "vendor management," "onboarding," or "facilities management") so your resume passes ATS screening.
