Does anyone know how to use the QuickBooks Fixed Asset Manager?

Hello there, @ajm01998. 

I'm here to lend a hand in fixing unexpected results when using Fixed Asset Manager (FAM) in QuickBooks Desktop (QBDT).

If the Accumulated Depreciation amount is not correct when posting a journal entry in QBDT from FAM, to resolve this, let's confirm the Accumulated Depreciation account for the Asset. 

Here's how:

1. Go to the Asset tab.
2. Click the General Ledger Accounts section.
3. Confirm that the correct account is selected for the Asset, Accumulated Depreciation, and Depreciation/Amortization Expense accounts.

Once verified, merge the Accumulated Depreciation account to the new Accumulated Depreciation account. Before doing this, I recommend creating a backup of your QuickBooks company file since account merging is irreversible. 

To merge the account, follow the below steps:

1. Go to the Lists menu at the top.
2. Select Chart of Accounts.
3. Right-click the old Accumulated Depreciation account and select Edit Account.
4. Add a number after the account name (Example: Accumulated Depreciation1), then select Save & Close.
5. Choose Accounts, then New on the Chart of Accounts window.
6. Create a new Fixed Asset Account named Accumulated Depreciation, then select Save & Close.
7. Right-click the old Accumulated Depreciation account and select Edit Account.
8. Remove the number that you added in the account name and select Save & Close. 
9. Click Yes on the merging account prompt.

Once done, retry posting a journal entry to QBDT from FAM.
