I like that it provides me with all my accounting needs, from inventory to general ledger functions in one place so nothing gets missed! It's not user friendly at times but if you're familiar this shouldn't be an issue - otherwise there are many other options available which do have better interfaces/features than coss itself does provide (ie Sage). Nothing really- just overall ease & speediness when doing our monthly bookkeeping duties compared w others who require more steps or time spent using their systems before getting accurate data back up into them each month via XERO integration etc.. The best part about this system is that it is very user-friendly and has a good interface. Also, the support service is also very good. The downside is that it is little bit expensive. There are a lot of features. So it is difficult to manage all features. Also, it is difficult to access all information. I would recommend this product to everyone who wants to manage all their operations in one place. I am solving my problems of managing all my operations in one place.
