Is there a "test company" in QB. I would like to set up a dummy CoA

Hello there, @john-sunphysio-c.

I'm here to guide you in creating a dummy account for your chart of accounts in QuickBooks Online.

You can use the trial version of QuickBooks Online so you can create a test company and a dummy chart of accounts. This way, you'll be able to explore the program before you enter your transaction on the actual account.

To do that acquire the free trial version, you may visit this site and select Free 30-day trial. 

After that, you can now start setting up a sample company file and create a dummy chart of account.

To add an account:

1. Go to the Gear icon and select Chart of Accounts.
2. Select New to create a new account.
3. In the Account Type drop-down, choose an account type.
4. In the Detail Type, select the detail type that best fits the transactions you want to track. 
5. Give your new account a name. Tip: Use the detail type description to create a name that describes what you're tracking.
6. Add a description.
7. If this is a sub-account of an existing account, select Is sub-account and then enter the parent account.
8. Now let's make sure the account in QuickBooks matches your real-life bank or credit card account. Choose when you want to start tracking your finances. In the Balance field, enter the amount in the account, and determine the as of date. Enter today's date if you want to start tracking immediately.
9. When you're done, select Save and Close.
