inventory, rather than capital assets, and the profits on the sale of
those properties are treated as ordinary income, subject to the self-employment tax.
Many expenses must be capitalized and allocated into each project, and then deducted when that project is sold.

- Direct materials

- Rent
- Indirect labor
