Navigate to Admin > Site Content > Web Content > Register Receipt Footer
You can add text to the footer of the email receipt sent to the customer directly after purchase. Many studios use the receipt footer to outline how a sale is applied.
If you don't see the Register Receipt Footer option, you can click on the Add Web Content option and add a new web content that can be used as the custom Receipt Footer. After this web content is edited, please go to Admin > Configuration > Studios > select desired studio > Custom Receipt Footer and select the custom footer desired.
