You bring both technical skill and a customer‑first mindset, including:

• 2+ years of experience in billing operations, accounts receivable, or finance support
• Strong Excel skills and comfort working with financial data
• Experience using Salesforce or a similar CRM
• Familiarity with Adobe Commerce (Magento) preferred
• Confidence communicating with customers by phone and email
