We are selling on 3 different stores, with the same products, but different language and this is fine for us.
-You need just one Shopify account to access all your Shopify admin. Easy and fast.
-Our home page isn’t always the same because we don’t do the same promotions depending on where our customers are. (ex: Mother’s day isn’t the same in every country).
Happy to give you more info if you need!
