We have been a Channel Advisor customer for just over 6 months and in that time we have managed to connect all 4 of the marketplaces we use taking the hassle out of stock management and rewriting the data over and over again to suit each marketplace or website.
Our channel advisor account manager is always available to contact if we need something new or something fixing. Also the support guys are excellent they contact you very quickly and always resolve your issues.
In the time we have been using Channel Advisor we have almost doubled our eBay business and are doing the same on amazon. They have such a good range of contacts in each marketplace to help you expand your business quickly and efficiently.
We wouldn't trust our online business with anyone else!
