Payment gateway for an online store, do I understand correctly?

Question

Payment systems

Hello.
There is a task to make it possible to pay for goods in an online store, but without going to intermediary sites, such as Robokassa and others.
Do I understand correctly that a payment gateway will solve my problem?
Which is better to choose?
Or are there any other options?

As an intermediate option, you can organize an invoice for your buyer in his personal account of the payment system, but in order to pay for it, he must, in any case, go to another site.
