How does selling on an online platform like Shopify impact taxes?

[IonutSutic26]

Hello there! I am willing to start an online business in Shopfiy, but I have some questions. Do I need to start my own company so I can sell? I am from Romania. And how does it work? What would my taxes be? Does Shopify handles VAT and other taxes? Will I be taxed per sale? Or do I have to get a personal accountant? Thank you for your potential answers!
