Updating your billing information is as easy as logging into your My.Pressable.com Dashboard.
After doing so, click on the Billing link in the left-hand menu:

On the Billing page you will see the plan you are currently on, plan upgrade options, a summary of your billing history & invoices, and finally a list of your provided payment methods. It is from the “Payment Methods” tab that you can add new payment information to be used in the future.

Please Note:
Collaborators do not have authorization to change any account information, including payment methods.
