You’re the connector, and you’re our subscription billing expert (m/f/d). When customers have questions about their invoice, subscription, or account balance, you give them a clear, correct answer, fast.

• Own accurate, on-time billing in NetSuite, from invoice runs and credit memos to revenue and billing schedule corrections

• Keep every interaction and resolution documented in our CRM/ticketing tools, so the next person picking up a case has the full story
• Help us get better by bringing your ideas on how to tighten up subscription management, billing, and support processes

Your profile

• Extensive, hands-on knowledge of NetSuite, including subscription and recurring billing, invoicing, credit memos, and customer records, and the confidence to troubleshoot issues independently
• Solid B2B SaaS experience with a strong grasp of subscription management: contract terms, renewals, amendments, proration, and the link between CRM subscription data and billing
• Very good written and spoken English, German is a plus.
• Comfortable using AI tools and cloud-based workflows to make your own work sharper and faster
• A structured, analytical mind and a preference for working closely with a team
