Best for: All round consulting work
Starting price: $9 per user/month (billed annually)
Free plan: Yes
Pros: Free Forever plan with wide features; deep customisation for client workflows
Cons: Timesheets and resource management need Business at $17 per user per month
ClickUp gives a consultant one place for tasks, docs, goals and time, and the Free Forever plan covers a surprising amount of that. You can build a separate space per client, set custom fields for engagement type or billing status, and keep templates for repeatable work such as audits, onboarding or monthly reporting. The Core plan at $9 per user per month adds unlimited storage, more integrations and advanced permissions, which suits a consultant who shares boards with clients.
The catch is that time tracking and resource planning sit on the Business plan at $17 per user per month, so the headline price is not the price of a full consulting setup. Storage on the free plan is capped at 60 MB, which fills fast if you attach client files. Still, for a solo consultant or a small practice that wants one flexible tool, ClickUp covers more ground than most rivals at the same price.
