This is a brilliant opportunity for a billing professional who thrives on accuracy, loves a good spreadsheet, and wants genuine ownership of a function that sits right at the heart of the business.

• Real ownership – you'll own the monthly billing cycle from start to finish, not just a slice of it.
• A team to lead and grow – manage, coach and develop six billing professionals.
• Variety that keeps things interesting – recurring billing, usage billing (CDR/SDR), margin assurance, supplier reconciliation and system improvement projects.
• Influence across the business – work closely with Commercial, Operations, Projects and Finance, with a genuine mandate to improve processes, not just maintain them.
• Hybrid working – flexibility to balance office collaboration with working from home.

• Leading, coaching and developing a billing team of six.
• Owning the monthly billing cycle, ensuring invoices are accurate, timely and error-free.
• Managing recurring and usage billing across telecoms and managed services.
• Validating and reconciling CDR/SDR usage data and supplier invoices.
• Driving margin assurance activity and identifying revenue leakage.
• Handling complex customer billing scenarios and exceptions.
• Partnering with Commercial, Operations, Projects and Finance to ensure seamless customer onboarding and billing.
• Building out billing processes, controls and KPIs that scale with the business.
• Producing management reporting and billing analysis using advanced Excel.

• Owning supplier invoice reconciliation and maintaining accurate COGS data.
• Producing supplier performance scorecards to support supplier reviews.
• Reducing billing errors to minimise credits and improve accuracy across the board.

• 5+ years' experience in a telecoms billing, finance or revenue assurance role.
• Proven experience managing and developing a billing team.
• Strong grounding in telecoms billing – recurring billing, usage billing, CDR/SDR processing and supplier reconciliations.
• A track record in margin assurance and improving billing accuracy.
• Advanced Excel skills – Pivot Tables, XLOOKUP, INDEX/MATCH, Power Query, and comfort handling large datasets.
• Experience with billing/ERP platforms such as NetSuite, Halo, aBILLity or similar.
• Sharp analytical and problem-solving skills, with real attention to detail.
• Confident communicator and relationship-builder across Finance, Commercial, Operations and Customer Success.
• Strong organisational skills and the ability to juggle competing deadlines.
• A continuous-improvement mindset – you enjoy making things better, not just keeping them running.
• A relevant finance, business or accounting qualification is a bonus, but not essential.

• Salary: £48,000–£55,000 (dependent on experience) + benefits
• Location: Wakefield, West Yorkshire — hybrid working
• Team: Managing a team of six
• Reporting to: Head of Billing & Credit Control
