Can you use BitPay anywhere?

I'm curious, could you elaborate on the reach of BitPay? Can it be utilized in a variety of locations or is it limited to certain merchants? Is there a way to verify if a business accepts BitPay as a payment option beforehand? And if I come across a store that doesn't currently accept it, is there a process to encourage them to start doing so? I'm eager to learn more about the versatility and adoption rate of this cryptocurrency payment solution.
