Basically, if we're using the Webflow Client billing and for whatever reason the credit card gets cancelled or it fails there should be a system in place to account for this.
Example: A client cancels the payment without telling anyone, so the first thing that happens should be an email sent out to the client and to the agency or designer. Saying that "if not paid within 3 days the service will end and your website will be locked". Ideally, there should be an email each day until that point. On the 3rd day, there should be a site-wide white-labled lockout screen urging the owner to call the agency or designer to get the service back online.
That would be great and it would allow many people to scale their agencies or companies very easily.
