How can an online store do without an online checkout?

Question

Electronic commerce

I called the companies providing online checkouts and one of the companies said that you can connect a payment system to the online store to choose from: Yandex.Checkout or Robokassa and then there is no need to connect the online store to the online checkout.
It turns out that the payment system itself assumes the obligation to send checks, notify the tax office, etc.
Is this true? And how, in this case, to connect the online store to the payment system?

Answer 1

No . Yandex.kassa will only send it directly, for example, to atoll.online, which will offer to rent 2 cash desks and 2 fiscal drives.
physically you won't have it. you will not spend cash on them.
pay more.
Individual entrepreneurs without employees have a delay for a little more time
