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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
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.
