Sitting by the phone, waiting for the order

You made your pitch. Now you're sitting by the phone waiting for the call from the customer.  Waitng to get the order.  I have one word for you:
DON'T.
You need to stay in touch with the customer who is in the process of making a decision.  You need to email him, call him, call on him in person, anything to let him know that you want the order.  Some of the approaches could be:  "here's some information I forgot to give you the last time", or "here's an update on the product", "if you're still having a difficulty making this decision, can I see you so that we can discuss your questions?".  Use any reason you can think of to stay in touch with the customer during the decision making process.  

MAXWELL'S LAW: THE LAST SALES PERSON STANDING GETS THE ORDER.
I play in a big band orchestra and the conductor at a recent rehearsal made a great point:  what the audience remembers is your last song.  You can mess up in the middle of the concert, but make the last song perfect and that's what they'll remember.  Be the last person the customer remembers and you'll get the order.
