A request to put everything on the website can hide two different needs. Prospective buyers need an explanation they can discover and share. Existing customers may need a private record, a status change or a document tied to their account. Staff may need a different view of that same work. Giving each audience a page does not settle who may read or change the underlying information.
Begin with three short lists: information anyone can use, information an identified person may see, and actions that change a business record. Add the business owner of each action. This often reveals that the first commission should be a stronger public site, a focused private workflow, or both with a clear boundary. It also makes it easier to compare a browser-based interface with an installed application without assuming that every mobile visitor needs an app.
