You can merge organizations. This is done when you have duplicate organizations or when you have a contact from an organization that was mistakenly added as a separate organization.
Please follow this guide to learn how to merge organizations.
1. Click the "Organization" that you want to merge to
2. Click on the "Cog" icon
3. Click "Merge Organization"
4. Select the "Organization" from the list
5. Click "Add"
6. Click "Merge"
The added "organization(s)" will merge with the initially selected organization. Data such as phone numbers, emails, and addresses will be incorporated into the default organization.
