These are templates (Apple Numbers and Microsoft Excel respectively) that follow the accounting model from Vending-Business-Information.com, as laid out by Dennis.
This sheet will do all of the percentage calculations for you as well as auto filling your "Route Totals" sheet. I recommend adding a new "digital binder" for every route you run.
To input a location, simply duplicate the template sheet and fill in the information from your location card. Then add that location to the formula on the "Route Totals" page and drag the new formula over all of the cells.
I hope this helps y'all avoid the confusion I faced when first starting out.
