How many companies i can add in single subscription

Welcome and thanks for dropping by the Community, @opsdxb.

In QuickBooks Online (QBO), you're only allowed one company per subscription. For a second (or additional) company, you will need to sign up for a new QBO account, because they must have their own subscription. You can also use the same login credentials when signing up and/or switching between companies.

Here's how:

1. Go to https://quickbooks.intuit.com/online/.

2. Choose a version of QuickBooks.

3. On the signup page, select Sign in.

4. Enter your login information and follow the on-screen instructions to set up the second company.

5. After that, log-in to QBO.

Once done, click the Gear icon at the top right to get to the Switch Company. For more information, you can refer to these articles:

• Create or add another company.
• How do I switch companies?

Please leave a comment below if you have any other questions or concerns. I'll be more than happy to help. Take care and have a great day!

1 QBO account = 1 company file

Consider QB Desktop should you having multiple company files to manage. Deploy a private cloud if required.

Intuit has abandoned the little guy.  I have 3 small individual company files in QuickBooks 2021 Desktop Pro.  In 2021 a 3-year package was purchased for $400.  No need for extensions like payroll, inventory, etc.  Now they want $650 per year!  That’s a 388-percent price increase! 

The online version, for the Simple Start level, for 3 company files is $360 times 3 or $1080 per year which works out to a 700% price increase!  What  a bunch of crooks.
