Commerce is one of the few applications we've seen that makes full use of the Secure Electronic Transaction protocol for secure shopping. Commerce also supports Secure Sockets Layer, which more sites are likely to use. Multinational features, such as foreign currency translations, are well-executed. Sadly, though, reporting is limited to a handful of basic summaries. For the real deal, you'll have to dig into the reporting capabilities of DB2.
Commerce is a chore that can only be described as painful.
It took us five tries, a complete rebuild of the operating system and a total of three days of working with the platform before we had any semblance of stability. The installation difficulty is partly due to the complexity of the products and partly due to their bizarre installation requirements. For example, to run the install process, you have to log on as a user with administrative privileges, but the user's ID must be eight or fewer characters in length - meaning you can't use the Administrator account. Adding to the confusion, Net. Commerce gives you a slew of default accounts and passwords to remember, a different one for each of the four components of the commerce suite.
