Job Description - Billing Administrator

We are Comex 2000

We’re the team behind the UK’s telecom networks—building, upgrading, and keeping the country connected! From fibre installs to 5G rollouts, we make it happen with innovation, speed, and a smile. If you love a challenge and want to be part of something big, Comex 2000 is the place to be.

Are you a detail -oriented professional with a knack for numbers and a passion for process? We are looking for a proactive Billing Administrator to take ownership of our revenue cycle.

In this role, you won’t just be "sending invoices"—you’ll be a protector of cash flow, a guardian of financial accuracy, and a key point of contact for our clients. Operating with independence and supported by a collaborative team, you will manage the billing journey from initial preparation to final submission.

What You’ll Do

As our Billing Administrator, your mission is to ensure timely and accurate revenue recognition. Your day -to -day will involve:

  • Precision Billing: Execute daily billing activities, managing exceptions and adjustments (DFEs) to ensure every invoice reflects our contractual excellence.

  • Account Stewardship: Maintain flawless client records and billing milestones, ensuring we are always audit -ready and transparent.

  • Collaborative Problem Solving: Partner with internal teams and clients to resolve queries, bridge gaps in data, and maintain healthy AR balances.

  • Continuous Improvement: We value your brain, not just your data entry. You’ll identify process bottlenecks and champion digital tools to make our workflows leaner and smarter.



Requirements

What You’ll Bring

  • The Basics: Strong background in billing, finance administration, or revenue -focused roles.

  • The Tech Stack: Proficiency in Microsoft Office (Excel is your best friend) and experience with ERP or specialized billing software. Power BI knowledge is a plus!

  • The Mindset: A solutions -focused approach with the critical thinking skills to handle routine tasks and complex discrepancies alike.

  • Communication: The ability to build long -term relationships with stakeholders and explain financial data clearly.

Education & Experience

  • Required: GCSEs (or equivalent) in Math and English.

  • Preferred: Experience in project -based environments (e.g., Telecoms, Construction, Utilities).

  • Growth Mindset: We are open to candidates currently studying for—or interested in—a Business Administration L4 qualification or a Project Manager internship.
