I have found eSellerPro to be an excellent solution to my multi channel selling needs. The product allows my company to sell the same inventory across three channels - Amazon, eBay and website cutting down on the management of sales and the potential for stock issues. I keep discovering new and useful functionality. The support staff are also very knowledgable and pleasant
Multi Channel eCommerce platforms are by their very nature complex and I think that part of the problem is sellers having unrealistic expectations as to the effort involved in getting up to speed with the product and implementing it in their organisation.
