The ability to send messages back & forth between customers, employees and suppliers in real time! I really like that it's easy enough anyone can use but also has features which make more advanced users feel comfortable as well (i'm not an expert at all). It would be great if you could set up your own account with multiple emails addresses so people know where they're going when sending them information or requests - this makes life easier especially during busy times of year such as Valentine’s Day/Mothering Sunday etc.. This system works best from being online 24 hours per day 7 days week however we have had some issues with our internet connection dropping out every now again making things difficult while working remotely over weekends / holidays sometimes too!! We've been able solve these problems by upgrading hardware devices though :).
