Filling out the Orders Billing and Orders Shipping information is necessary for the orders to be synchronized over from your store.
For both sections, it is recommended to add your own company details as this information will be forwarded to the suppliers. They will use your billing information for creating the invoices when they fulfill your orders.
The shipping details you add will be used by the suppliers only when you place a wholesale order for their products - in that case, they will ship directly to you.
Otherwise, the suppliers will ship to your customers, the shipping details they provide will be used.
