What I found most valuable in Salesforce CRM is its reporting feature because it's extensive and it's very accurate. I also like that you can move opportunities by stages. I find that feature very important and very useful because it helps you understand where opportunities get stuck, and at what stage it is currently.
An area for improvement in Salesforce CRM is that there's still a lot of manual input you need to make. If it could pick up things automatically from an email and auto-populate, that would make the tool better. Another area for improvement is that the Salesforce CRM connector for G-suite does not work effectively.
