How often do you inventory the cans/bottles in your machines? I would like to be able to keep track of my products, to make sure my machines are not giving freebies and such. How often do you guys inventory?
Normally, you would inventory every time you fill. You would know what your set "full" level is (total amount of cans). I have seen people put magic marker marks part way up the row to set a level on low volume machines. Write down what you add to make it full and compare that against collections.
