How to organize the acceptance of payments on the website of the online store?

Question

PHP

Greetings.
There is a working online store. The company that owns this online store has so far worked only with legal entities, mainly small wholesale, accepted payment only by bank transfers to its current account. There has also been no delivery yet. We did not work with individuals in order to facilitate accounting and reduce the number of reporting and possible checks.
Now there is a task to "upgrade" the company to be able to work with retail buyers-individuals.
The main thing to do is to resolve issues with payment and delivery.
Organizational, legal and technical issues arise.

There are different services for accepting payments on the site. All of them differ in convenience for customers, for stores when connecting and working, as well as in prices. What do you advise? What systems do you use and what good or bad things can you say about them? What commission do you pay? How difficult is it to connect them?
The main thing I wanted to clarify in this matter relates to the technical part of the organization of accepting payments on the site.
But if someone additionally shares their experience in organizing payment and delivery in other aspects, for example, in the specifics of interaction with the accounting department for various online payments, I will be grateful.
Few of those. data:
The site is written in php, Symfony 1.2 framework.
When choosing a payment intermediary tariff, you need to focus on the minimum monthly turnover.
The company's current account is opened in Moscow Sberbank. (in this regard, the option of using the acceptance of payments on the site using the acquiring of Sberbank can also be considered. True, only general information is on the Sberbank website).

Answer 1

bank acquiring is much cheaper than any wallets.
I recently also encountered the issue of accepting card payments on the site, my choice fell after long comparisons with the acquiring of RosEvroBank. I chose it for many reasons: low commission, ease of installation, money transfer is very fast, it is not necessary to have an account in this bank and a lot of other gadgets that are easy to use
