Can I use one quickbooks for multiple companies?

One QB Online account is for one company file. You need to use QB Desktop to manage multi company files.

Thanks for posting your concern here in the Community space, mesinaweng1108.

I've got the information you need about setting up multiple companies in QuickBooks Online (QBO).

Yes, you can have as many companies as you'd like under the same QBO account. However, each company you set up requires an additional subscription. Thus, you can use the same login credentials in signing up and switching between companies.

Here's how:

1. Go to https://quickbooks.intuit.com/online/.
2. Then, choose a version of QuickBooks.
3. Click Sign in on the signup page.
4.  Enter your login information and follow the on-screen instructions to set up the second company.
5. Once done, you can log in to QBO.

After creating the new account, you can follow the steps in this article to switch or toggle between companies to manage them more efficiently: How Do I Switch Companies?

Moreover, this guide will provide details on how to switch between company files and move them to the same account: Manage multiple company files.
