A free basic version of the software is available to the customer free of charge. It is usually packed with limited features such as limited freedom to customize and limited access to advanced functionality. However, all features become fully available when the user chooses to subscribe or outright purchase the license to use the software. Offering a free version of a software or platform is a mutually beneficial marketing strategy for businesses and end users. For the company, it is an opportunity to demonstrate the value of its software or platform. That's why companies usually program the free basic version with enough features and functionality to satisfy customers while satisfying their desire for more. For the customer, it offers the opportunity to understand the software before deciding whether or not to pay for full access.
