It takes awhile to get "into" ChannelMAX as it is a very comprehensive system. But once there, you will find a complete system for managing your ebay business. It does everything, inventory, listings, templates, email, invoicing, etc... I got frustrated on several occasions becuase it is a bit overwhelming and the documentation is skimpy. But with the excellent support from Paul, you get over the bumps very quickly. I highly recommend you give it a try. I am a Platinum Powerseller and I have tried almost all the AMS's out there. I can honestly say that Channelmax is the only one I have used that did not disappoint me in some way.
