While Calendar offers a free Basic plan and a fee-based Pro plan that both deliver a number of features, both are only made for one user and you may need something that works for your small team.
The Business Plan offers all the features found in the Basic and Pro plans. However, up to 50 of your team members will also be able to use it. Other features exclusive to the Business Plan include team analytics, CRM integration, and white label capability.
