Assuming you want to know how to bookkeeping for fixed assets:
When you purchase a fixed asset, you need to debit the asset account and credit the cash or accounts payable account.
You will then need to set up depreciation schedules for each of your assets. This schedule will list the expected life of the asset, salvage value, and depreciation method.
Once you have your depreciation schedule, you should record depreciation expense on a monthly or quarterly basis. To do this, you will debit depreciation expense and credit the corresponding asset account.
