Finance & Billing Coordinator

About the Role

CubX is looking for a highly organized Finance & Billing Coordinator to support our Controller in managing day-to-day financial operations. This role is ideal for someone who is self-managing, detail-oriented, and capable of owning tasks from start to finish — but not responsible for running the finance department.

You will handle AR, AP, bookkeeping, employee expenses, client billing, and vendor payments with precision and consistency. We are looking for someone who thrives on structure, accuracy, and keeping financial workflows running smoothly.

What You Will Do

• Handle Accounts Receivable : client invoicing, payment tracking, reminders
• Manage Accounts Payable : vendor bills, credit cards, recurring payments
• Process employee reimbursements and expense reporting
• Perform daily bookkeeping in QuickBooks Online
• Reconcile accounts and verify all financial transactions
• Maintain accurate client billing records and update project charges
• Track renewals, subscriptions, and vendor services
• Prepare spreadsheets and basic financial reports
• Improve and streamline workflows under the Controller’s direction
• Communicate with clients and vendors as needed
• 2–5+ years experience in AR / AP, billing, or bookkeeping
• Strong proficiency with QuickBooks Online
• Strong Excel / Google Sheets skills (VLOOKUP, PivotTables, formulas)
• High attention to detail and strong analytical skills
• Extremely organized with the ability to self-manage tasks
• Able to follow established processes while identifying improvements
• Comfortable supporting leadership, not acting as it
• Experience in a service-based business or MSP is a plus
• Competitive pay with performance-based growth
• Paid time off and company holidays
• Health, dental, and vision insurance options
• 401(k) retirement plan with company match
• On-site gym for employee wellness
• Modern, collaborative office environment
• Ongoing training and professional development
• Opportunity to work with cutting-edge technology
• Team events and employee appreciation initiatives
• Strong company culture focused on innovation and teamwork
