How do I change the billing address on my account?

If you want to send your payment receipts to a different person (accounting, an office manager, etc) you can do that within your account settings. 

Note: You'll need to be an admin user in order to make this change.

Head to SettingsAll SettingsSubscription. Once you're on that page scroll down to the Invoices section:

Then click on the "View Invoices" option.

From there you'll head to the "Receipt Settings" area.

Check the "Send me my receipts" box and a field will pop up where you'll enter the new billing email address

And you're done! All future receipts will send to that email address going forward.
