You can set your account's billing email, find your billing date, and customize your receipts.
Your personal account's primary email is where GitHub sends receipts, credit card or PayPal charges, and other billing-related communication.
You can find out when you're next going to be billed for your GitHub plan in your personal account settings.
You can download past receipts at any time from your account settings page.
If there's specific information required by your company or country, you can add that information to your GitHub receipts.
