Hi Cladinesfashio,
As we don't really have any details about your current setup, I'm gonna have to take a few guesses and they are just guesses. Assuming this is your website and it's hosted by this service and you can currently accept credit cards on your site, it is possible to also use Square as another option to process your transactions. There is a catch, you may need the help of a Developer - this link provides some details. For some other web hosting services, Square offers pre-built ways to connect and process transactions. If I'm missing something concerning what you have in mind, then providing some more info as to exactly what you want to do would be helpful for others here to offer some thoughts.
