How do I record purchase and sale of treasury bills and record unrealized gains and losses on them?

I can help you record the purchase and sale of treasury bills in QuickBooks Online (QBO), @accounts573.

To begin, we'll need to set up a treasury bills account. Here's how:

1. Go to the Transactions menu then click Chart of Accounts.
2. Tap New to create a new account.
3. Please select the option you see below for our next steps.
4. Choose Other Current Asset as the account type and name it "Treasury Bills."

For more details, refer to this article: Add an account to your chart of accounts in QuickBooks Online.

Then, let's record the purchase of treasury bills:

1. Go to +New and select Expense or Check.
2. Choose the bank account used to purchase the treasury bills.
3. In the Category" section, select the "Treasury Bills" account and enter the purchase amount.

To track unrealized gains and losses, you can create a journal entry to record the change in value. The process can be complex, so I recommend consulting with a professional accountant or financial advisor for specific guidance tailored to your business and the applicable accounting standards. To easily get a ProAdvisor, you can visit this link: Find an Accountant. 

Moreover, you can generate several reports in QuickBooks Online that tell you about different aspects of your business and customize them to focus on specific accounts or filter for specific things.
