Their system is very buggy... it will work for a few months on one computer, then suddenly stops working... they'll advise to change to a different browser, or state they no longer support Apple computers (thanks for that, we don't all have PCs here at our office); often their website is down. Half the time they want us to update the downloaded program, the other half the time they want us to log on and only use it online. Their monthly fees are way too high for small businesses, and their staff is hard to reach (to put it politely). If you can find another service, DO SO!
