Worksection
Worksection is an all-in-one project management platform that replaces five separate tools — a task manager, planner, time tracker, work chat, and file storage — with one system on a single per-user price.
Built for teams of 5 to 50+ — agencies, IT, consulting, manufacturing, and construction — especially teams that bill clients by the hour. Manage tasks and subtasks, plan with Gantt charts, Kanban boards and a calendar, track time with hourly rates for client billing, discuss work inside each task, and keep files where they belong. Reports and dashboards turn project data into decisions.
Unlike tools that sell time tracking and client billing as paid add-ons, both are built in. Free for teams up to 5 users. Worksection has been doing this since 2008 — GDPR and ISO 27001 certified, available in 11 languages.
