Sales is not customer service, often people confuse being nice to customers and customer service with being an effective salesperson. Customer service is only one aspect of it, it’s not Sales though.

Almost everything we do in Sales is about putting your client/customer at ease and overcoming any fears they may have, to give yourself the best opportunity to positively interact with the client/customer and achieve a successful sale
