Hi there, @jwardhana.

Based on your screenshot, you're already in the process of inviting your accountant. To continue, click the Next on the right bottom part of your page. After that, your accountant will receive an invitation via e-mail. Let them click on the hyperlinked text and follow the on-screen instruction so that they can link to your QuickBooks company.

There is no subscription fee for accountants. Once they are logged in, they can connect to your company file. To access your company, he or she can click the Post trading drop-down beside the Hamburger icon.

I added a screenshot to show you how it looks like.

If you have difficulties in inviting your accountant, I suggest contacting the QuickBooks Online Care team to perform a screen share. Also, during the process, please don't forget to communicate with your accountant so that you can guide him or her on how to link your company to their QuickBooks Accountant version.

Count me in if you need anything else. I'll be here to help. Keep safe.
