Greeting, @BookkeeperWytch.

Yes, you can create a second company file for your business without affecting your husband's company file. You just need to enter your business name, industry, and business type to create your company file. I can guide you in doing so.

First, you'd want to secure a copy of your husband's QuickBooks license number and product code. You can now download and install QuickBooks to your device. Here's how:

1. Download your version of QuickBooks Desktop.
2. Open the installer file you've downloaded (QuickBooks.exe).
3. Follow the onscreen instructions.
4. Accept the software license agreement, then select Next.
5. Enter your Product and License numbers, then click Next.
6. Select Express and then Next.
7. Click Install.
8. When it finishes, select Open QuickBooks to get started.

Once completed, you can now create your own company file. You can follow the steps below:

1. From the No Company Open window, select Create a new company
2. Choose the Express Start button.
3. Fill in the necessary information.
4. Click Create company.
5. Follow the on-screen instructions to finish the setup

Also, you can create multiple company files in one QuickBooks Desktop license. You can refer to this article for more information: Create QuickBooks Desktop Company file: Overview.

I want to ensure that you have the optimum configuration for your business, so please feel free to let me know if you have additional questions. Have a wonderful day.
