What do you need to sell goods via the Internet in the US and Europe?

Question

Online shopping

Hello friends! A question. I want to sell goods in the USA and Europe. Through the Internet, something like an online store. Do you need any documents for this? What payment system can you choose? PayPal?
If we exclude the moments of creating and promoting the site, do we need any documents, registration of a company for the normal functioning of an online store in the United States?
If we take Russia, many online stores operate without any individual entrepreneur, they calmly resell goods for a high cost and have revenue from this.
