How does commission and transaction time work for electronic sales?

[Vladyslav3]

Good afternoon, I am selling electronic equipment. My company is registered in Hong Kong, but clients are from Ukraine. There are several questions.
1. When paying for my goods on the site using a visa or mastercard debit card, what will be the additional commission or fee for your services on your part?
2. When the customer has paid for the goods, how long will it take for the money to be credited to my account?
3. I will need to withdraw my money to a bank account or according to the card number, what will be the additional commission in this case? And how long will the withdrawal of money take?
