I've got the solution for you to delete the accounts you don't need, COR115.

Though you're unable to do this in batch, you can remove the accounts on the recurring transactions or delete those templates one at a time. This will let you inactivate accounts in the Chart of Accounts. If you use them on your items, you'll have to un-assign them or inactivate the items.

To remove the accounts on the recurring transaction or delete the transaction template:

1. Click the Gear icon.
2. Choose Recurring Transactions.
3. Double click the template name or click Edit.
4. Remove the line items (accounts) by clicking the Trash icon on the right side.
5. Click Save.

To un-assign an account in an item:

1. Click the Gear icon.
2. Choose Products and Services.
3. Edit the item and change the income and expense accounts.
4. Click Save and close.

If there's only one account item on a recurring transaction template, you can just delete it.

If there's anything else that we can help, please go back to this thread.
