Managing Fixed Assets
You can keep track of GL balances for fixed assets by creating GL accounts (Ledger -> Accounts -> New GL Account) and setting the Account Type to Fixed Assets.
You can manage fixed assets more in depth and have the system calculate depreciation by using the Inventory -> Assets module.
The Assets module can be used for service businesses as well to keep track of equipment that is onsite with customers. Assets that are tagged to specific customers (Owner field) can be added to service orders providing the ability to monitor all work that has been done on a particular piece of equipment.
