Drop Shipping
If you have decided to not stock anything, then you probably want to drop-ship products where you have an established warehouse/factory ship the products on your behalf. You would basically pick the products in their catalog(online/offline) you want to sell, and create those items in your site’s database. In a nutshell, when your customer makes the purchase on your site, you receive payment directly from them, and once you’ve verified payment, you then place an order with your drop-shipper (online or offline), and have them ship the order to your customer. You would basically pay the warehouse/factory your cost plus the shipping charges. The difference between your net sales amount minus what you have to pay them and what you charge your customer is your profit.
