how can i be paid for services with Bitcoin?

One of the biggest flaws of Bitcoin is that there are few to no place around that accepts payment with it as a currency.

As I'm just starting a remote therapy schedule in my psychology clinic using cognitive Behavior therapy, i thought of using Bitcoin universal approach to use it as a form of payment, which would help instead of approaching different types of currencies, like Yen, USD, Euro…

The issue is, i don't really know how to start asking for Bitcoin. I just make an Invoice QR Code or are there any app that helps us?
