POS receipt emails are a useful place to include invoice links for customers who complete an in-person order and choose to receive their receipt by email.
With Sufio, an invoicing app for Shopify stores, customers can access their invoice directly from the POS receipt email, along with other documents related to the same order.
The invoice link allows customers to view the online version of their invoice.
From there, they can download or print the invoice and view other documents related to the same order.

To add a link to the online version of the invoice in the POS receipt email template:
- In your Shopify admin, go to the Settings → Notifications → Customer notifications page.
- In the Point of Sale section, click POS and mobile receipt.
- Click Edit code and insert the following code snippet into the Email body (HTML) field:
- Click Save to apply the changes.
For customers who only need a downloadable file, you can link directly to the PDF version of the invoice.
