How to add the company Capital?

Welcome to the Community, @akram-okeili-com.

To add company capital in QuickBooks Online (QBO), all you need to do is to set up an equity account and record your deposits from there.

Before doing so, please note that if you’ve connected your bank account, there's no need to record them. Just categorise the transaction associated with your deposits.

To set up an equity account, here's how:

1. In QBO, go to the Accounting menu at the left pane to get to the Chart of Accounts page.
2. Select the New option at the top right. 
3. In the Account Type drop-down, choose Equity.
4. In the Detail Type drop-down, pick Owner's Equity again.
5. Hit Save and Close to complete. 

After that, you can now deposit the capital to the equity account. Check out this article and proceed to Step 2 for further guidance with the process: Track personal money or investments to your business.
