Project Management/Team Collaboration Tools
These project management solutions and/or online team collaboration tools are ones that have a Free Plan available. These solutions are extremely popular because they allow users to try the services without having to commit financially and then scale up in cost only when and if they determine they will truly get a benefit by paying for the service.
Free Plans differ from Free Trails in that free trials are limited by a number of days, typically 30. Free Plans provide the user with a free offering on an ongoing basis as long as their needs don't exceed the limits of the free plan.
