If you're from the US, UK, etc then you'll have many options such as Stripe, 2Checkout, Square, Clover, Zen, Revolut, etc. If not then even if you open a company in those countries you'll be pretty limited with just a few options, mainly Stripe and maybe a few other ones.
If you have a Saas or digital product you can look at merchant of record companies like Paddle, FastSpring, etc but they only pay 1-2 times a month.
