Tools and equipment that wear out
A melter, a bench scale, a label printer: things you own and keep are not stock, and now they are not treated like it. Each item has its own record under Assets: what it cost, how much it has depreciated, what it is worth now, and, when it finally goes, why.
Depreciation is straight-line and charged monthly. One button catches every item up to the end of last month, and a month is never charged twice. A tool bought on the same receipt as your materials becomes an asset rather than stock.
