Thank you for posting in the Community. Let me share ideas about editing company information in QuickBooks Online.
Based on the error message that you got, you require access rights to change any of the company's business information.
Your admin didn't enable the editing capability when you're added as a user. Therefore, you can contact your admin and ask to grant you access to complete the changes.
Once the permission is granted, you can now edit the business information:
Click on the Gear ⚙ icon. Then select Account & Settings.
