• Arrange business travel, including flights, hotels, ground transportation, and itineraries.
• Help prepare expense reports, organize receipts, and route invoices and purchasing documentation to the appropriate teams.
• Maintain organized documents, shared files, contact lists, and administrative trackers.
• Help coordinate team meetings, company events, offsites, catering, and visitor arrangements.
• Track action items, send reminders, communicate progress, and follow up on open administrative tasks.
