Exporting/Importing

Hi folks: Using Sage 50 Premium 2019 . I have a full-on bookkeeper who works in one town, and a sales clerk in another town.I want the sales clerk to be able to Export her sales invoices and send the resultant IMP file to my bookkeeper to bring in to her copy of Sage. Is this possible? I looked at the I/E function, but it seems really limited, and I can't see a way to do just the invoices. 

If this isn't the way to do it, does anyone have any other methods?
