I can pretty much estimate everything as far as mowing, chem app's, mulching, etc. But the factory we do work for is wanting to pay a monthly fee for maintaining the property now. My question is how do you calculate for snow removal in that contract. I can go by my figures from last year but what if it snows or ice's more. Do you add a little buffer in the figure, just in case? How do other professionals do it? This is our first big factory account and I need a little advise, thanks.
