I am not 100% sure how Google pay works in your country but in India its loaded with Bhim UPI technology that helps us pay anyone who is on UPI network just with their mobile number and yes we can easily receive payments from others and can pay all bills through itI did not realize that you were also able to receive payments through Google Pay. I only use it to make purchases myself but I will have to look into it a little more to see what else I can use it for.
Being able to receive and pay money through it would also be ideal for me.
