I have a branch office in TX and CA. I'm looking for a solution to share PDF documents between the two branch offices. Basically, the TX branch will scan invoices to a "public" folder for the CA branch to approve. I'm trying to avoid having the users send these documents over email back and forth. Neither branch has an IT staff onsite so I'm looking for an easy solution. Maybe users could upload the PDF to a cloud based service. Any ideas for this?
