Within Teamwork Spaces, you can view your subscription invoices via your subscription settings.
Note: Only site administrators in the owner company can access the subscription information for your site.
Click your profile image in the top right of your site and choose Subscription from the dropdown menu.
Scroll to the Invoices subsection of your subscription settings where you can view a list of all of your historical subscription invoices. This list will include the invoice date, number, subtotal, tax amount, and total cost.
Clicking an invoice date will open a PDF version of the invoice in a new browser tab, with options to save or print.
