Abstract: The present invention relates to a sales system that can increase transparency in cultivation by disclosing various situations occurring in the cultivation process to consumers, comprising: a crop image server that receives and stores images of crop grown in a crop production area; a reservation server that posts sales information of the crop using the images of crop stored in the crop image server and receives presale orders for the crop from a buyer terminal; a growth image transmission server that transmits the images of the reserved crop to the buyer terminal; and a pricing server that calculates the expected yield in consideration of risks that may occur in the process of growing the crop and calculates the unit price of the crop.
