Hi Chris,
I think the statement "No thanks. such tells me that their product must be bad." might be a bit harsh. :) Unlike other PSAs, we sell an on-premise application that automates your entire business - from award-winning CRM, email marketing and analytics, to quoting, service (of course), inventory, purchasing, billing, and automated payment processing. It takes a big commitment to change your entire business, and we've found that extensive product tours before purchase are a great way to level-set expectations and avoid confusion. We also provide 800 support for everyone in your company when you come on board, not just support for a dedicated champion. We are committed to our customers' success, whether they are a small shop or they are running over 400 concurrent users like our largest customer.
Your point about a trial system is duly noted, however, and certainly something we kick around periodically.
I appreciate the healthy discussion! :)
