We did need a little tech support and found them to be very helpful. Great product, great support. The offline Commerce Buddy is missing many simple functions like printing labels or exporting data to a multiuser system. The script headers say the perl cannot be edited or merged with other programs. This limits CartIt's use for any serious online commerce.
Customer service is very poor as well.
2 Oregon, USA Support took a while to get in touch with me, but they did fix some things. For CGI based shopping cart systems, nothing can touch CartIt. 1 Missouri, USA I have installed CartIt a number of times and use it exclusively now. The scale is 1 - 10, with 1 being poor and 10 being excellent. Please be objective, if everyone receives a 1 or a 10, the ratings aren't very useful.
