What are the CMS for an online store of one product?

Question

CMS

There is some software that we want to sell online. Accordingly, you need to raise some site for a couple of pages with a description of our software and prices. There will be a free version without restrictions and a paid one. Hence the question. Is there a very simple CMS that would make it easy and simple to sell _one_ some product? You don't need a lot of functionality. Multilingualism will be a big plus. We really need integration with popular payment gateways.
What do you advise?

Answer 1

Look towards landing pages with a ready connection, you can implement multilingualism with the help of subdomains /ru/ /en/ and so on.
Also look at opencart - I have not seen ready-made solutions, but there is definitely multilingualism and integration with payments.

Answer 2

You make a landing page with the function of ordering and paying for goods.
