The convenient builder allowed us to customize the system to meet our company's needs without the need to involve programmers. The automatic mailing from the company, which takes into account discounts, promotions, and bonuses for each client, turned out to be very useful and significantly saves time. I also appreciate the feature that allows tracking the purchase history of each client, which provides the ability to see what exactly each client has purchased, as well as their address and other personal information. The technical support works well, and I had to contact them a couple of times.
