Payment question

I'm a new owner and don't worry I'm still at least 5 years from even breeding much less selling. But I understand most of shipping protocols but I need some ideas on how to take payments like from an online customer or someone who is too far to simply drive. I would just like to know some opinions on how I could do this

PayPal and square both give you the option of being able to invoice, and both will accept credit cards for you.

Paypal is the most common

PayPal, Square, Money Orders, Checks, Cash (for local purchases)
