I am opening up a coffee shop and I was trying to purchase a Square products, but every time I try to make the purchase, the process is being declined. Is it because the shipping address is different than the card address? Help needed urgently! Thank you.

Hi @StationCoffee Have you reached out to your card issuer to learn more about the declines? What did they say?
