I review clients' transaction lists across multiple customers, ensuring accuracy and identifying any billing discrepancies. Before generating invoices, I verify all transactions to maintain accuracy. I provide daily reports on billed and unbilled invoices, escalate invoices requiring managerial approval, and promptly upload finalized invoices to the client's portal. In addition to managing billing and invoicing, I have experience in content moderation, ensuring online safety and compliance. This includes screening and filtering harmful content such as extremism, violence, and exploitation to protect users, uphold digital brand reputation, and maintain platform integrity. I review large volumes of text, images, and audio to ensure compliance with regulations and community guidelines. Alongside billing and content moderation, I have experience in customer service, handling refunds, exchanges, and service requests. I managed high-volume calls, resolved customer inquiries, maintained detailed records, and provided after-sales support to ensure customer satisfaction.
