I'll be your guide today in changing your company's Master Admin, nnaziz.

When transferring the Master Admin access, you'll have to ensure that the user is already added as a Company Admin. If not, you can follow these steps to set up the user first:

1. Click the Gear icon in the upper right-hand corner of the Dashboard.
2. Under Your Company, click Manage Users.
3. Click the Add user button in the upper right-hand corner.
4. Select Company Admin, and then click Next.
5. Enter the new user's profile information.
6. Click Save.

Then, let the user check their email to accept the invitation. Once done, you can follow the steps given by my colleague above to successfully transfer the Master Admin rights.

If you need more help with this, just let me know. I'll be around to assist you further.
