Receipts and Invoices/Timesheets & Letters

I am looking to maximise the use of the Receipt Hub for not only receipts but also Sub Contractors Invoices and Invoices from Other Suppliers and also copies of general letters etc.

My question is what is the best way of doing this. Am I better using the Quickfile App for receipts and then simply sending emails to quickfile for copies of invoices I have that have either been emailed or have otherwise scanned. This seems to work very well other than there does not seem to be a way to create sub folders within the receipts hub and document manager where you could file locally dependant on sub contractors name etc. The reason for wanting to do this is to isolate individual sub contractors invoices and their timesheets. I presume this could be short cut if I simply add these email attachments into sub folders directly via drop box.

Or, as I have signed upto the premium version of Cam Scanner would this be the best all round option. Any advise would be greatly appreciated
