I have been doing fertilzing and pest control apps for a few years now and have grown quit a bit over the past two. For the longest time I just "guessed" on pricing rather than measuring and pricing according to what the application are requires and takes. Therefor, I would like to get more accurate on my profit margings and what not. I am not at all asking the "what do you charge" question I am only asking for suggestions on things such as X for 5k and X + ? per every k after that and/or discounts for larger properties such as X for first acre and X + ? per acre after? Any suggestions would be aweomse as I am serious about upgrading from my PG to a z-spray and taking on a lot more customers this year.
