Books & Inventory integration

Books & Inventory integration

I really, really, REALLY would like to subscribe to Inventory but I see so many things holding me back. 
The latest is to see that in Books -  receiving bills | Selecting open purchase orders shows no indication of the PO being received in full or partially received in Inventory !

Is this due to me only having the free Inventory version or just an oversight ?

If I convert a partial receive to a bill in Inventory it rightly only allows the received items to be billed - would this happen in Books ?
Most of my bills are entered via scanned documents in Books - docs is not available in inventory !
A bit of a dilemma going on here guys - not as integrated as advertised ???

Books for sales / office guys & Inventory for Warehouse staff is how this really should be working in my mind ?

Package creation in Books from invoices/Sales orders with statuses of "To fulfill" (& other user defined options) would solve a lot of problems as we could then give warehouse staff access to the packages only module & they would then not see the monetary figures of sales.

Hiding the monetary figures in purchase orders & items is another issue then though :-/
Warehouse guys DO NOT need to have access to this sort of information !

Currently I send all items & sales info to Google sheets for processing in the warehouse - I'd sincerely love to have it all in one package !
