How do I create a Sandbox Test Company to experiment with a new chart of accounts?

I can help you in generating a sandbox test company file, Heidi.

To begin with, you'll need to set up and create a developer profile. Following the creation, you'll automatically get a sandbox company. Moreover, you can make up to 10 sandbox companies.

To produce a new one, please follow these steps:

1. Log in to your developer account and go to the API Docs & Tools tab.
   
2. Select Sandbox and click the + Add a sandbox company option.
   
3. Choose QuickBooks Online Plus or QuickBooks Online Advance. If you've chosen QuickBooks Online Plus, picking your Country on the dropdown is a requirement. When created, the Country is unmodifiable.
4. Once done, hit Add.
