I have quickbooks Essentials 12-month subscription. One holding company has been entered. I do books for a few non-profits. How would I add these organizations?

Good evening, barbsinn-hotmail.

Welcome to the QuickBooks Community. I'd be happy to provide some information.

Thanks for connecting with us here. QuickBooks Online is a great tool to help keep your books balanced. Since you plan on doing bookkeeping for a few different companies/organisations, I feel you'd benefit by checking out our QuickBooks Online Accountant page. With QuickBooks Online Accountant, you can add your QuickBooks Online clients to your firm so that they are all in one place. I hope this helps! I will also be leaving this post open for other community members to comment their experiences.

If you have any other questions, feel free to reach back out here.

You should consider using QB Desktop to manage multi company files. If you don't need to run any add-ons (e.g QB Payroll, QB Payments), you can use QB Desktop with a non-subscription license.
