Automatic capture is the right instinct
Start with what is correct about the approach. A CRM that depends on people typing notes will always hold an incomplete and flattering version of events, because logging is the first thing a busy rep abandons. Salesflare positions itself around removing that burden by capturing activity automatically, and any CRM that does not take the same view is asking its users to do administrative work that software should be doing.
So this is not an argument against automation. It is an argument about coverage. Automatic capture is only as complete as the channels it can observe, and the question worth asking before you choose is a simple one: where does the important part of your sales conversation actually take place?
