Updating your billing information could not be easier, it is as easy as logging into your my.pressable.com control panel.
After doing so, click on the Billing link in the left-hand menu.
On the Billing page you will see a summary of your billing history, followed by a list of your provided payment methods. It is from there 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.
