Create a new invoice subscription
Note
Even though a subscription is skipped, it will still still count towards the duration limit. For example, if the duration is 5, and the first subscription is skipped, only 4 subscriptions will be sent.
Invoice recipient
Please note that you cannot send an invoice to yourself (on the same email address that you used for your Checkbook.io account).
