Public relations work is ongoing, relationship-driven, and difficult to quantify, which makes billing especially challenging. Tools like Muck Rack help manage media lists, but they don�t address billing or time tracking. Tympi allows PR freelancers to track outreach, pitching, follow-ups, and reporting time within a single system. Retainer invoices automatically include detailed time logs, helping clients see the effort behind results. Compared to Muck Rack, Tympi focuses on the business side of PR, ensuring professionals are paid consistently for their ongoing work. Tympi helps PR freelancers prove value, reduce churn, and maintain predictable income.
