Before sending the offer, please read the link to the demo eshop! We are looking for someone who will create an e-shop based best on woocommerce - we can discuss ideas for other open source solutions. With features such as at https://demoshop.promotron.com/. It is a connection to xml feedy suppliers, not only for products, but also for printing technologies, including the connection of prices without printing and with printing - according to the permitted technology. It is also necessary to merge categories - if one supplier has a category of pencils / pens and the other pencils / pens - so that it appears under one category. Connection to automatic update of stock and prices - once a day. For example, update products from the feed once every two months - or manually. Most things can be done by the wp-allimport plugin - we own it. It is an import of about 100000 products plus printing technologies. It also includes an onlene design - inserting a logo with a preview of the product. Ideal variant and automatic preview of the logo on all products - as in the link. Please - first read the link https://demoshop.promotron.com to understand my requirements. Thank you
