Billing Administrator

Billing Administrator

Eastleigh – Office Based

£30k - £35k

About Us

We are a creative communications specialist that has spent nearly 20 years helping over 30,000 businesses grow through website design, SEO, PPC, social advertising and business-grade telecoms, all delivered in-house from Southampton. Backed by private equity investment, we are scaling rapidly through both organic growth and strategic acquisitions, while preserving the entrepreneurial, people-first culture behind our success.

The Role

We are looking for a meticulous Billing Administrator to own order processing and customer account maintenance on our billing platform. Every new order, upgrade, downgrade and credit passes through this role, so accuracy directly protects both our revenue and our customer relationships.

Reporting to the Financial Controller, you will work closely with sales, customer service and provisioning to make sure what we sell is what we bill - and that every adjustment is applied correctly, first time, with a clear audit trail.

Key Responsibilities

Order Processing:

• Process new customer orders promptly, checking pricing, contract terms and product configuration before they are committed.
• Validate order paperwork against what has been sold, querying anything inconsistent rather than passing it through.
• Work with sales, customer service and provisioning to move orders from sale through to live billing.

Billing Platform & Account Adjustments:

• Maintain customer records on the billing platform, applying upgrades, downgrades, additions, cancellations and tariff changes.
• Raise credits, refunds and rebills in line with policy, ensuring each is properly authorised and documented.
• Support the monthly billing run, carrying out pre-bill checks and resolving exceptions before invoices are issued.

Queries, Controls & Reporting:

• Investigate and resolve billing queries from customers and colleagues, explaining charges clearly and without jargon.
• Keep records so every adjustment can be traced and evidenced at audit.
• Assist the finance team with reconciliations, reporting and accounts administration.

AI & Continuous Improvement:

• Use AI and automation to speed up routine processing, checking and reporting tasks — a core expectation, not a nice-to-have.
• Suggest and help implement improvements to billing and order workflows as volumes grow.
• Support the integration of newly acquired businesses into our billing processes.

What You’ll Bring

Essential

• Experience of billing within a telecoms, VoIP or connectivity business.
• Exceptional attention to detail - you spot the wrong figure or mismatched contract term before anyone else does.
• Experience in an accounts, billing or order processing role in a busy commercial environment.
• Confident with systems and data, with solid Excel skills and the ability to learn a new billing platform quickly.
• Well organised, able to prioritise high volumes and work to deadlines such as a monthly billing run.
• Clear communicator, comfortable explaining charges and querying discrepancies with colleagues.
• Genuine appetite for AI and automation as everyday productivity tools.

Desirable

• Exposure to a subscription or recurring-revenue billing model.
• AAT qualified or studying towards an accounting qualification.

What’s On Offer

• Competitive salary commensurate with experience.
• Support towards a professional accounting qualification for the right candidate.
• A varied role with visibility across finance, sales and operations.
• A vibrant, collaborative culture in a PE-backed business on an ambitious growth trajectory.
