IP for an online store?

Question

Individual entrepreneur

In general, I decided to start trading via the Internet (specifically Shopify). I realized that you can’t do without registering an IP. Tell me, who has experience, what and how to do, if I trade mostly with the West, half print on demand and half dropshipping from aliexpress. Of particular interest is the situation with the cash register. How, sobsna, to be with her, if I don’t see my goods?
PYSY: Don't tell me that you need to test everything first, etc. and then think about IP and cash desk. Everything has already been done, the store is ready and even advertised a little. You just can't pay for anything.
UPD: Before answering the question, I propose to find out how payment works on Shopify and stop recommending receivers for the CIS. Especially those who need a separate button on the site. Imagine yourself in the place of a buyer who, instead of his native Paypal, sees some kind of robocash.
And yes, the cash register and the payment acceptor are two completely different things.

Answer 1

Look towards the online checkout. It is tied to the site, does not require a physical cash desk.

Answer 2

you can do it without an individual entrepreneur and a cash desk, the Internet is full of things that accept payment without registering an individual entrepreneur. and then make a conclusion on the card. But this, as you understand, is at your own peril and risk, for non-payment of taxes and other things.

Answer 3

if you register paypal on an individual entrepreneur in the Russian Federation, you will not be able to receive payments from business paypal accounts, only from personal accounts.
If you sell in foreign currency, then PayPal gives a bad exchange rate, you lose 4-5% somewhere.
at the online checkout, punch checks at the exchange rate of the Central
Bank
