Why?
Selling on the phone is more effective, so why not combine it with online technology (especially for higher ticket items)?
How?
A website with the technology that enables the sales person to help the buyer by controlling what is happening on the web page the buyer is on now (on the seller’s web site.) The sale will either start with a phone call to the buyer by the sales person, or a request by the buyer while on the web page. The sales rep will then continue in parallel on the phone and collaboratively on the web page, controlling and guiding the buyer in both mediums (if he is any good), enabled by the web site technology that allows him to change things on the fly on the web page the buyer is seeing (and only that page – anyone else browsing that oage sees the standard version.)
