How to get spreadsheets (specifically Google Sheets) to automatically populate in Quickbooks Desktop?

My Cpa is old school and is not well versed with technology. I renovate houses for a living, around 75 yearly.  We already have many spreadsheets setup for internal expense tracking that is being entered via google sheets.  My thought was to set up our current spreadsheets on a document that would either in real time update quickbooks or could be imported seamlessly so there would not have to be double entry.  

We need our spreadsheet views for company purposes or I would have the project manager just input them into Quickbooks but there is also a learning curve and I assume with the technology this should be something simple once the "new spreadsheet" was setup to include the needed titles, classes ect that could integrate seamlessly again without double entry.

Any suggestions or help would be greatly apprecaited.
