Hi Jim,
Thank you for interesting in our EShop Shopping Cart extension. Regarding your questions, once there is an order is placed, there are some notification emails will be sent:
1. Notification email to send to Admin's store
2. Notification email to send to customer/guest
3. Notification email to send to suppliers/manufacturers
These emails include full of information of order and they can be configurable from the back-end side of component.
Hope that my answer is clear. If you have any pre-sales questions, don't hesitate to let me know.
Sincerely, Giang
