just as an example: new item bought (lets say a computer) - the expense of the item goes to account 0030 (office equipment). The depreciation would then be a debit to account 8004 (Office Equip. Depreciation) and a credit to account 0031 (Office Equip. Depreciation) posted at the end of each month/year (depends on your circumstances).
