You don't need a big close, as many sales reps believe. You risk losing your customer when you save all the good stuff for the end. Keep the customer actively involved throughout your presentation, and watch your results improve.
I've learned that people will seldom let you down if they understand that your destiny is in their hands, and vice versa.
There is a time to provide advice and offer an opinion, and there is a time not to. Don't be too quick to offer unsolicited advice. It certainly will not endear you to people.
Delegating doesn't mean passing off work you don't enjoy, but letting your employees stretch their skills and judgment.
To me, job titles don't matter. Everyone is in sales. It's the only way we stay in business.
Too often, sales reps simply regurgitate their presentations and expect to land the sale. It doesn't work.
