Which engine for an online store to choose?

Question

Online shopping

I plan to create an online e-commerce store, providing paid services, setting up and creating game servers, are there any of these free ones?

Requirements:
* Billing system
* Payment system: Robokassa, Interkassa
* Product cards
* Balance replenishment
* Ticket system
* File sales

Tell me which engine is better to take for review? And which is better not to touch?

Answer 1

A few years ago I was going to launch a hosting of game servers, I scored when I looked at the estimate for the development of PU, billing and others like it. There is no ready solution here. An online store selling files with attached payment orders is full of them, but screwing PUs with servers, their deployment, etc. is another story, self-written and expensive.
