I echo all of the complaints in this thread.  QBO is the most frustrating software company - always seems like QB "experts" have no real-world experience.  This last "solution" is just as bad.  I need to be able to see the products/services, but I don't want my clients to see it.  The "fixed" functionality requires that I add and remove the product/service each time I convert an estimate.  AND add to that that I'm also changing the setting for everyone else using the system.
