How is Salesforce different form CRM?

I would really like to try out this door company’s services. I heard a lot of great things about Caldwells. Here’s the https://caldwells.com/interior-doors/shaker-doors to their site and I would gladly appreciate your thoughts about them.

Salesforce platform is much more than a CRM, It comprises:

Sales process automation

Partner management

Community

Customer support

Marketing automation
