I’m about to pursue a course in CRM (likely Salesforce). Can you guys breakdown what CRM is and how it benefits it’s clients?

Backstory: Ive owned a small hospitality business for 8 years now and it’s stable and got a great brand & presence in my city (could always earn more) having 10 employees now.

So I’m looking at a change in direction while keeping the business in my back pocket so to speak – so I’m deciding to take a 6 month long course in CRM (I believe it’s Salesforce or similar product)

I have 0 experience in IT (though plenty of friends in the industry in various roles)

I’d love if someone gave me a breakdown of their job or how CRM plays a role in providing value to whoever their client is.

I hope I’m making sense here haha

Thanks
