I have entered invoices from vendors as Labor and Materials. I now have to adjust due to knowing the true costs of materials. I would like to make a journal entry, but it does not allow it to show up under that vendor. For example. XYZ Company has $40,000 in labor and materials. I need to adjust so their records show they have $28,000 in labor and $12,000 in materials. How do I make a journal entry so it shows on their report? It doesn't appear properly if I make the JE.
