TaskBill.io
Synchronize your tasks, track your time, and invoice your clients
TaskBill.io is a tool for teams and freelances to track time spend on client tasks. If you bill by the hour, TaskBill allows you to easily send invoices for unbilled time. If you do project based billing, TaskBill can help you determine the actual cost in employee time spent on each client and their related tasks.
TaskBill syncs with Basecamp, Asana, Monday and Trello so you can easily start and stop timers or log hours against the tasks you already have in your project management system.
