As a commercial lines account manager, you work as the liaison between insurance companies, agents, and clients. Your duties and responsibilities involve responding to requests for information and documentation, handling renewals of expiring policies, processing claims, and assisting with audits. You also maintain documentation for new and renewing business, answer questions about coverage, process applications, and follow up on overdue accounts. Some employers also require you to contribute to marketing activities, and since you maintain relationships with clients as well as team members throughout your organization, you need creativity and multi-tasking skills.
