Within Teamwork, you can integrate your projects with Xero and export invoices to your Xero account.
To use Xero on your projects, you will first need to enable the integration at site level.
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.
Enabling at project-level
Once enabled, go to the Settings area of your project and select the Integrations tab.
Under Xero Invoicing, toggle on the option in the upper right corner to enable the integration.
You will be immediately redirected to Xero's website to log in to the Xero account you wish to associate with Teamwork and grant permission for the integration to access your account.
The organization and base currency (set in Xero) will then be linked to the project.
Once your project has been connected to Xero, you will be able to choose Xero Online as an export option for your invoices.
