Add ability to enter a mandatory base charge.
It would be good to be able to add a base cost to an event (different for each event). A minimum order amount doesn’t work for covering extra costs. For example, my lab for volume sports photos has a $25 min order. If I have a late order where print cost is less than $25 using a minimum order amount just cuts my profit. The only way to not cut into profit is to add a mandatory base cost adder.
For portrait or commercial work this is not an issue for me. It only applies to the volume side of my work.
