Timeliner is video agency management software for teams that need to review footage, manage editors, collect client approvals, and track payments in one system. The site positions it as an operating system for video agencies rather than a general-purpose project manager.
Its workflow combines timecoded media review, project and task management, branded client portals, version control, and payment tracking. The product also exposes WhatsApp, Slack, email, REST API, and webhook-based notifications so approvals and project updates can connect to existing team tools.
