Hi,
Thank you for reaching out here in the DocuSign Community.
Our accounts envelope allowance is based on sends, taking this into consideration once you have successfully sent the document out for signature it will count against your quota regardless of whether or not the document is completed.
For more details on our billing system, you can refer to the guide provided below:

Please don't hesitate in letting me know if you have any follow-up questions and I will address them as soon as possible.
Best regards,
Alejandro R.
