Hi @mdsmith1 - Regarding your above question
> Suppose I have a client at "carpenter1.com" who would like to use my software service. how do I get my files on his server so he can use my code and how would he login?
To share your app with a customer, you'd invite them as a user to your Retool organization: https://docs.retool.com/org-users/guides/add-users#invite-users If you have multiple customers, you may want a separate Retool org for each so they can't see each others' data. In this example, one Retool org would be carpenter1.retool.com and you'd invite your customer contacts as users to that org.
They'd then log in directly to the Retool org at carpenter1.retool.com .
If you developed an app in that org that you want them to see, you could share the URL like https://carpenter1.retool.com/apps/586cfb4c-4063-11ee-a434-efe239b4e948/[app-name] They'd see it when logged in. Keep in mind they'd still see an "edit" button.
I know you've been working through similar questions in this thread - we hear your feedback! I understand this has all been really frustrating, especially realizing that it's only possible to restrict user edit access to "view only" on the Business plan. Please know we've shared your feedback internally about bringing permissions controls to the Team plan, not just Business. We'll keep the plan structure topic consolidated to the other active thread, but wanted to acknowledge this. 
Hope it makes sense that you would "share" your Retool apps with your customer by inviting them as a user to your Retool organization, and they'd log into it directly. Hope you have a happy holidays and new year!
