Hello @kyusun Lee,
Thank you for reaching out, and a warm welcome to the Docusign Community! We are absolutely delighted to have you here and can't wait to share our knowledge with you.
I understand you're considering purchasing additional envelopes, and your question is if they are valid until the end of your subscription, which is December 15th. This is a great question!
Yes, the additional envelopes purchased will be valid until the end of your current billing cycle. This is because purchasing additional envelopes increases your subscription allowance before your next billing date. Unused envelopes do not carry over to the next billing period.
