Karlie here from the Shopify Support Team! I'm happy to discuss different aspects of Shopify with you, feel free to ask any questions you might have. Signing up for the Shopify platform would provide you with an Admin where you can set up products, shipping, discounts, sales channels and create your own online store. You can use your admin to manage and organize orders and customers as well. You can use the Shopify platform to sell products through your own online store, social media platforms, on mobile devices, and brick-and-mortar shops.

I hope this has answered your question. If not, or if you have any further questions please let me know. I will be happy to help!
Hello again, @miafrance!
Karlie here from the Shopify Support Team! It sounds like you're interested in dropshipping. If you're looking for a specific product, like a kitchen appliance then you can always look into dropshipping through an integrated app like; Oberlo, Modalyst, or Spocket. If you have any questions about the apps or app plans then be sure to reach out to the app developer by using the 'Support' section of the app page in the Shopify App Store. Be sure to catch a free video course on dropshipping, here, if you're interested.
When it comes to transferring your other websites over to the Shopify platform, you have a couple of options. You can either migrate your store over manually, like so or you could use an app to help you. You can check out some apps like; Cart2Cart, Excelify or one these options to help you with that process.
Let me know if you have any further questions - I'm happy to help!
