Office Administrator & Billing Coordinator Full or Part-Time Available

Job Description

Job Description

We're a growing professional services company looking for a reliable, detail-oriented administrator to help keep our back office running smoothly. This is a hands-on role where no two days are exactly the same — you'll be supporting billing, operations, and the owner directly.

Hours: 8:00 AM – 12:00 PM (Part-Time) or 8:00 AM – 5:00 PM (Full-Time)

What You'll Be Doing

• Process incoming receipts and expenses in our billing system, ensuring costs are accurately recorded and assigned
• Generate and send client invoices on schedule; follow up on outstanding balances and escalate overdue accounts as needed
• Collect and verify employee expense receipts and compile reimbursables for each pay period
• Request, track, and collect Certificates of Insurance from carriers and vendors; maintain an up-to-date COI log
• Collaborate with ownership on back-office priorities, keeping tasks organized, clearly defined, and moving to the right people
• Track and record employee PTO and vacation requests; maintain accurate balances
• Receive and organize incoming equipment and deliveries as needed
• Keep the office stocked and orderly, including managing supply reorders as needed
• Maintain organized digital and physical filing systems

What We're Looking For

• Prior experience in an administrative, bookkeeping, or office coordinator role
• Working understanding of basic accounting principles — specifically how debits and credits flow through a billing system
• Strong attention to detail and follow-through; you don't let things fall through the cracks
• Comfortable working closely with a business owner and managing your own workload day-to-day
• Comfortable speaking up and coordinating across the team when something needs attention beyond their own desk
• Proficient with common office tools; quick to pick up new software

Why Join Us

We're a tight-knit team that values people who take ownership of their work. You'll have real responsibility from day one and direct visibility into how the business operates. Flexible scheduling is available for the right candidate.
