We've had SE for about 6 years. While we were small (under $1m in sales) Once we surpassed a million and added two new users everything fell apart. And, it is not our server. We have a new server that handles customers 100 times our size. Absolutely awful support and terrible platform. They forced us to upgrade to the newest version and we've had nothing but problems. Circle of death continues to appear and slows us down while on the phone with customers. Absolutely terrible. Worst part of it is that they won't address the issues and their technical staff does not have the expertise to develop solutions. And its impossible to get someone higher up the chain to actually listen to us. Look elsewhere.
