First, you need to decide where you will source your products from: wholesalers, retailers, manufacturers or third-party assemblers. Choose based on quality, delivery time, cost and the profit margin you can add.
Then, you need a website on which to host your store: you can build your own, hire a professional to build it, or use an existing site like Amazon
. On the site, you need to list all your products with detailed specifications, high-quality pictures, and warranty information.
Last but not least, you need to have a plan for the storage, shipping and delivery of your laptops. You also need to be prepared for returned items as well as offer customer support. This is where an existing site like Amazon can potentially be advantageous (see below).
