Thank you for bringing this matter to the Community, Lissa. You can add a new accountant by clicking on the Gear icon in your QuickBooks Online account. Let me provide you with the full steps to add one.
In the Accountant email field, enter your accountant’s email address.
Select Send invitation.
Select Text a code to verify your identity. This sends a verification code to your registered mobile number.
Enter the code in the Verification code field, then select Continue.
Once the invitation is sent, your accountant will receive an email prompting them to join. You will be notified via email once they accept the invitation. After acceptance, your accountant will be able to access your accounts through QuickBooks Online Accountant. If they do not receive the invite, you have the option to select Resend invitation.
