BrandsSync | Dropshipping

I am using this application. However, there is no standard for the names of the products and especially the size information. The products do not have sufficient descriptions. It does not have a standard size information for shoes numbers. Some shoe sizes are giving in US sizes, some in UK, and some in EU. For example, the Nike - Wmns-Outburst yakkabi number has been sent to you with the US information, U.S. Polo Assn. - NOBIW4156S9_YS1 EU was sent to you, Adidas - YUNG-1 was sent to you by UK. This is causing confusion in my customers. When I gave this feedback to the company, they were not interested either. Just send us a size chart so that we can see which size up to what size.
