You can update your payment details directly through your site if you have a current Teamwork Projects subscription and you need to update your payment details - for example, if your payment card has been replaced or you need to change to a different card.
If you need to change or add a tax number, you'll need to use this process too.
Go to the site settings menu in the top right of your screen and choose the 'Subscription' area:
Click on the Update payment details button under your subscription plan and enter your updated details.
Note - only site administrators in the owner company have access to this area.
Under the plan that you're currently subscribed to, you'll see a link to update your details.
