Within Teamwork, you can disable the Xero integration for an individual project or for your entire site.
To remove Xero from a project, go to the Settings area of the project and select the Integrations subsection.
Under Xero Invoicing, toggle off the option in the upper right corner to disable the integration for the project.
Once disabled, users will no longer see Export to Xero Online listed in the export options modal when exporting an invoice.
Note: Only project administrators and above can manage integrations on a project.
Disabling at site-level
You also have the option of disabling Xero at site-level, meaning the integration cannot be used on any project on your site.
Click your profile icon in the top right corner of your site and select Settings from the dropdown menu.
In the Settings area, go to the Integrations tab and click Connect beside the Xero option.
Note: Only site administrators in the owner company have access to the site settings to disable integrations.
