About half of the project management tools on the market offer a free plan. It is free forever, and the free plans on ClickUp and Trello offer great functionality for an individual or small business to get started using this type of software for project management. However, as you’d expect, they do not offer all the functionality that the company has up their sleeve and as your business grows and you find the tool more and more useful, you will begin to find yourself limited by what’s on offer in the free plan, and will want to change across to a paid-for plan. The reason that they are able to offer free plans for free, is that people are happy to pay for the more comprehensive paid-for plans, which make enough money to cover the free versions.
