How do you put my commodities on the buttons?

We don’t, you do. The system is designed so that you don’t need a programmer to set up or maintain the screens that your scrap buyers use. You create the list of commodities that you will buy, and you specify a button for each commodity. You control the label, the font, and the color of the button. Using our unique button menu maker, you then place the buttons on the screen wherever you want them.
