What about offering a whitelabel product where I am the account owner and can spin up an independent database for each of my clients with their own login credentials while I still have master access to each?    
I would literally sign up tonight and deploy this next week to my restaurant clients who want the ability to update their food menus at will and in complicated ways. Static site front end with a live menu API and Excel-style interface for them to edit in? That&#x27;s the perfect solution for what these kinds of clients want&#x2F;need.
