Hello everyone, I'm working on a project where I believe I'm going to need to utilize multi-tenancy. But I could possibly be misunderstanding what a multi-tenant app is.

If I'm building SaaS for banks and banks can add client accounts, how do I structure the app in a way that when someone signs in, it can determine whether that user is a bank or a client? That way a bank will have access to data that a client wouldn't - all while being on the same system if that makes sense.

Can anyone point me in the right direction here? Or even share experience if you have worked a similar multi-user type app.

Thanks!
