Great piece of software to use. The ease with which you can launch on new channels and marketplaces was one of the main benefits. Some of the other tools that the Channel Advisor platform provides has really helped to benefit our business - digital marketing module has driven growth for us, as has the algorithmic repricer amongst others!
It's also worth mentioning Catalyst - the Channel Advisor conference - as a worthwhile experience all around. 2nd Year attending this year and was not let down!
