A free trial allows users to try out a product before they buy it. It gives them access to any features offered under paid plans, without having to pay anything upfront or sign up for an account.
Free trials are one of the best ways for SaaS companies to attract new customers by giving them firsthand experience with the product before they make their purchasing decision. It also allows them to collect valuable feedback from those customers so that they can improve their product over time based on customer needs and wants.
