The DVP of technology is inherent to its scalability - why only support admin level API when it constricts C-Suite's ability to delegate tasks?

In many respects I very much enjoy the 7shifts experience and what the app does well it really nails. However, the reality of an industry who is so diffuse in their tech stack is that an inability to be interoperable, compatible and flexible towards the material reality of the customer won't lock them in in an apple like way, but instead encourage them to jump ship to services who will allow for that flexibility.
