Welcome to the Community, @RahulILLLP.

I'd be glad to help you add your accountant to your QuickBooks Online company. There's no need of getting in touch with our support for this process.

In this process, you'll need to ask an active e-mail address and the name of your accountant. Then, you can add them to your company. After that, your accountant will receive an e-mail to verify if they are the ones you've added. You can tell your accountant to confirm that email so that he will be successfully added to your company.

Here's how:

1. Go to the Settings and select Manage users.
2. Click on the Accounting firms tab.
3. Enter your accountant's email in the box and select Invite.
4. After your accountant confirmed the verification, you'll see the status to Active instead of Invited.
5. If they haven't received an email from QuickBooks, you can send the invitation again by clicking Resend invite in line with the accountant's name.
6. You can also click the Delete button under the drop-down icon if they are using another email, then redo the process to add them again.

I've added some screenshots for your additional reference.

To know more details on how to handle the added users in your company, you can check out this article: Invite an accountant to review your accounting in QuickBooks Online.

I've also added this article for your future task whenever you need to check the transactions made by your accountant or other authorized users in your QuickBooks company: Use the audit log in QuickBooks Online.
