Billing is a vital and complex part of our business. You'll be working in the heart of our business, in a friendly team delivering an industry-leading standard of support to our customers. Our work is a mixture of essential monthly billing tasks and technical work. For a few days each month, the focus is on executing the monthly billing processes. We’re a complex business with multiple products, customers, and revenue streams, so our billing team handles large quantities of data from a variety of sources. Using tools such as SQL and Python, we transform raw data into clear, understandable information shared with a wide range of stakeholders, including customers and teams across Sales, Commercial, Finance, and Product.

Beyond our core billing responsibilities, a significant part of the role involves continuously improving processes, supporting the introduction of new products and services, investigating data anomalies, and resolving issues to ensure the accuracy and efficiency of our billing operations.

• Provide clear and concise reports and be able to demonstrate an understanding of the data contained within.
• Working with our commercial and product teams, understanding the offers they have built for our customers and how these translate to billing.
