Which CMS to choose for a very large online store?

Question

csv

Yes, yes, I have already read dozens, if not more topics on the forums. The second evening I'm stuck, trying to save some honestly earned small savings, that is, I'm looking for a relatively inexpensive option for an online store, in which more than 400k items are expected.
So, picking up saliva from the keyboard, I will try to explain what is required.
There is a Chinese store . He swung to become a representative in his region, that is, to create an almost copy of the store (not in design).
The functionality is approximately the following:
- implementation of the 2co payment system;
- multilingualism (minimum Russian + English);
- search for goods by criteria of color, material;
- choice of delivery method;
- Synchronization with social media networks;
- preferably a block that displays similar products depending on the ones being viewed;
- other modules that may or may not be mentioned, like the shopping cart, feedback, registration, etc.
Actually, the functionality, it seems to me, is quite primitive. The question is, which engine will pull such a quantity of goods? And how much money will it take to optimize or finish it? I posted a task on freelance - my comrades offered for 5000 uye, which is categorically not suitable because of the limited budget.
In terms of functionality, I really liked prestashop, but it’s more like up to 50k according to reviews. Bitrix does not fit all for the same financial reason. I'm looking for something relatively inexpensive. I dug up almost all the engines and got completely confused.
Guide the wanderer on the right path!

Answer 3

Have you considered Magento? Many large Chinese (and not only) stores use this engine. At first glance, the store on your link is spinning on it. Of course, they use all sorts of enterprise-versions, but the announced functionality can also be added to the CE version, I think it should work on the declared volume of goods. Of course, for your requests, you will need adequate hardware and competent software configuration (web server, cache - very important for magento, database). The system is very flexible, many extensions are paid and not so much.
In terms of finances: if there is no experience in the planned business or very little (judging by the question), unfortunately it will not be possible to save much. Even if you do everything yourself, you can spend so many man-hours on this business that in the end it turns out that in the financial equivalent of resources, no less than the amount announced to you was spent, and the result is not quite what was expected. It is clear that hiring freelancers also does not guarantee that you will receive the desired product in a short time or at least the agreed time, but it can free up your own resources. In any case, you have to take risks, otherwise the business would not be a business.

Answer 4

How much does prestashop cost?

Answer 5

you gave a good answer. but there are several big minuses regarding Magenta. this is the laboriousness of the dopilka and the lack of good specialists, which flies into a pretty penny. plus a very voracious engine, which makes no sense to use it without a dedicated line, and this is 100 per month, which is also not ice at first. but vote accepted :)
I, as a person who hasn't stuck his nose in longer than html, should rely only on freelancers ..
what about opencart? I often hear laudatory odes, albeit an outdated system. But again, I'm afraid it won't work.

Answer 6

look then towards opencart. A strong Russian community, there is almost everything out of the box. what you need, and the rest is put by modules. Many people work with him.
