What's wrong with our sales team/strategy?
thorax: Yeah, I like the code idea.Perhaps have the sales people give the customers a discount coupon identifier (5-10% or something) when they call. When the customer purchases, if they use the discount code, the sales person gets some part of the commission.Not only does it help you track who got the commission, but it might increase conversions of people who are interested enough in the product to call you.
