My business sells rigid substrates to fabricators. Materials such as PVC, acrylics, high density foam, aluminum sheet, etc. We have installed a large panel saw that will allow us to cut our sheet stock to size for the customer. I need to develop a web based, or mobile app that will allow my business to take a custom cut order, determine the best stock size that will allow the best yield for that order, and how many sheets of that stock size it will take to fulfill the order. Then I would like it to compute a fee to the customer for the labor involved with the custom cut. This will help me determine how many sheets of a certain material i need to sell in order to meet the order specifications, and how much money to charge the customer for the labor involved. I need it to be easy to navigate and have an intuitive hierarchy. The employees who would use it aren't mensa members.
