Billing Administrator

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.

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.

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.

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.
