I have an accountant to do all that for me !!
I do keep a note of every single sale I make and how much of each type of produce goes into my veg boxes or to the local Farmers Markets though this is more to help me identify what has been a commercially successful crop and what I need to rethink for next season.
I price my veg based on a number of supermarket prices, other local box scheme prices or demand e.g new season veg -especially my tatties, broadies and peas - these are the veg that attract customers to my farm gate sales - once I have them there I sell them other veg they didn't know they wanted !!
