I currently have a customer who is successfully operating an ebay store. She would like to develop a website, however managing inventory between the two is challenging.
She has asked me to act on her behalf in developing a full ecommerce website capable of handling 500 immediate products and capable of handling up to 5,000. Website must be able to accept paypal and credit cards (merchant account). It must be very simple to upload new product.
Most importantly, if an item is sold on ebay, it MUST update the inventory on the website and vis versa (if it is sold on the website, it must update Ebay). If the inventory reaches 0 it must end the item on Ebay.
