You can send your Basecamp or Backpack invoices to someone other than the account admin

Want to send your Basecamp or Backpack invoices to someone else besides the account administrator? Go to the Account page and choose the link "Change invoice email address and custom field." (Note: Only the account admin will see this option.) There you can specify a second email address to receive invoices. You can also enter custom text that will be included on each invoice.
