Hello! The companies I am working with is considering shifting from QB Online to QB Enterprise. With this in mind, I have the following questions: 

1) How elaborate is QB Enterprise's User Access Feature? Say we have a sales team, can we allow them to ONLY make estimates and invoices but NOT EDIT? Can the management also restrict their access to financial statements?

2) How can we transfer our files from QB Online to QB Enterprise? What data can we transfer seamlessly and what data in QB Online that cannot be transferred?

3) I am currently working for 2 companies, both of which are using QB. If we were to buy the licenese key for QB Enterprise, can both companies use them or only 1 license key will work for one company?

4) In QB Online, only the sales invoice and the estimate can be customized via importing a style from MS Word. Can QB Enterprise do this as well? If so, can it also import custom styles for sales receipt? In QB Online, it doesn't have that feature. 

EDIT: 

5) Is there a way I can have a demo of the QB Enterprise using my company?

6) It says one of the features of QB Enterprise is that it can accomodate 5 users at a time. I will be available the 15-user package. Does that mean this version can accomodate 15 users in real time?

TIA!
