Hello all. So I just recently opened a shop here and made my first sale. However, I'm not seeing how to invoice for it. Can someone offer some assistance?

Thanks in advance.

How I do it is just send the invoice to the email that you have received.

When you receive an email that someone bought you will have their direct email and send them the invoice with
payment instructions.

I have paypal so I send them the invoice and paypal email address, or make sure its their paypal email and I send them the request directly
from paypal.

The transaction notification will provide you with the name/email/address of the buyer, you can then engage to decide what shipping and paying options are the best. Usually it's Paypal but there are other payment schemes (Venmo, Wise, etc.) depending where you live.
