I like that it is easy for my customers to pay their invoices in one place, rather than having them send me money orders or cashiers checks which were then mailed back to get paid by us! It also makes keeping up with all of our accounts easier as well since they are kept together instead of being scattered across several different systems we use at work. There isn't anything about this system specifically; however there has always been glitches when using any sort of online payment software/systems (Paypal included). Sometimes things don’t go through properly so you just end-up not getting your funds until after paying fees etc., but sometimes everything works fine too where nothing happens unless its supposed to happen. Keep an eye out if something doesn't seem right though because often times what looks simple may actually be more complicated behind the scenes. We've had issues before.
