Can i add a (pty) ltd company to quickbooks online free trial?

Adding Pty Ltd company in QuickBooks Online isn't an option, Jennann.

While the option is unavailable, I suggest consulting with your tax advisor to consider alternative options that would be suitable. They can offer personalized recommendations regarding the appropriate business structure and name to use in QBO.

You can check this article for more details on how to modify business information in QuickBooks Online: Change your business name, contact info, or VAT # in QuickBooks Online.

In addition, here's a link to adjust your settings and turn features on and off in QuickBooks Online to personalise it to your preferences: Edit company settings in QuickBooks Online.

You can post any time if you have further concerns regarding managing your company settings or other relevant issues. I'm always ready to assist.
