About ActiveCollab

Overview

ActiveCollab is a productivity and collaboration workspace for growing service businesses, combining project management, time tracking, workload management, client communication, estimates, invoicing, and reporting in one place. From a task to an invoice, it keeps the full workflow in a single tool.

First released as an open-source product in 2006 and developed fully in-house since 2007, ActiveCollab is used by over 50,000 teams and more than 200,000 people worldwide. Agencies and consultancies rely on it to keep client work organized, profitable, and on schedule.

Key Benefits

  • Manage unlimited projects, tasks, and subtasks with List, Kanban, and Gantt views.
  • Track time on tasks with a stopwatch tracker and personal or team timesheets.
  • Plan capacity and balance workloads across projects to prevent burnout.
  • Create estimates and convert accepted ones into projects in one click.
  • Send invoices and collect payments through Stripe and PayPal gateways.
  • Keep clients and teams aligned with in-app chat, discussions, notes, and task comments.

How It Works

Teams set up projects, assign tasks with start and due dates, and record time against each task as work happens. Workload views surface availability so managers can rebalance, and accepted estimates turn into projects that flow through to invoicing and payment collection.

Use Cases

  • Agencies manage client projects, time, and billing in one workspace.
  • Consultancies track profitability and capacity across engagements.
  • Creative and design studios collaborate with clients and manage deliverables.
  • Software development teams organize tasks, dependencies, and releases.
  • Interior designers and small firms record project hours and send client invoices.

Why Choose This Product

ActiveCollab has been developed 100% in-house since 2007 with a fair pricing pledge and no outside investors. Every plan includes native desktop and mobile apps, live chat and video support at no extra cost, and the option to self-host on your own server.
