Syncee for Suppliers

I think a merchant that has not connected or sold anything through your catalogue should not be able to rate your store, because it makes no sense to me. They comment on things they know nothing about and give you a bad score with no experience. It needs to be a requirement that they have gone through with at least one sale. Also, some merchants expect, for example, customised packaging but don't want to pay for it, so I think they are buying into an idea that they can just open a shop and will have no cost. Maybe do a small manual to people starting a store so they know that there are costs even if they are lower?
