It's been a while since I did the LONG audit. Yes, you need the employee(s). The last group I did took me 45 - 60 minutes and had 52 questions. I always submit them at home with my computer. It is inefficient to submit while I am on my route, because I could use that time to do more shops. I shop my route first and then submit all shops after I return home.
You need only print the pages one time except for the page that the manager signs. Instead of printing a set of pages for each shop, I use a different color pen for each location. A pack of colored pens last years and is much cheaper than ink and paper for a printer.
