We currently run a 'paperless' process which involves scanning and filing GRNs and delivery notes, matching them up with invoices in another folder, checking the invoice is correct, moving them all to another folder then accounts will open the invoice again to be entered on Sage.  This is very time consuming, the same documents are opened and closed and read countless times by several people involved in the process which is not 'lean'. I'd like to find the most efficient way of conducting this process.  I think the most efficient process would be for 1 person to match the invoice with a GRN on Sage and approve it in the same action, which then gives accounts an list of approved batch of invoices on Sage which can be bulk processed, so they don't have to open the PDF invoice again.  Trouble is I don't know if this is possible in Sage or how to do it if it is possible.  It would be a huge time saver for our company.  Any ideas  how other people conduct this process would be very helpful.
