How do you get the materials on the expensive menu ? As in for transactions . All my come up with is office supplies

Hi jjw-installation The self employed product has fixed categories in accordance with the categories set out in the HMRC SA103f, we're unable to change these categories. you enter a description within the transaction indicating what the materials relate to..
