As a legal billing coordinator, your job is to invoice each client, manage financial accounts, and otherwise help record information about the billable legal services provided to each client. Legal billing coordinators compile information and bill customers on a predetermined schedule. You apply retainer funds, process write-offs, and execute complex billing processes. This job often involves communicating with attorneys, clients, and secretaries, so strong communication skills are crucial. You may be responsible for creating new billing formats, producing monthly reports, operating electronic systems, and ensuring client confidentiality. You can work for a single large firm as an employee or multiple smaller firms as a contractor.
