Neto POS supports emailing receipts directly to a customer at the end of a sale.
Once you have completed adding products to a sale, you can apply payments to the sale.
Click Pay Now on the bottom right of the sale screen.
Process your payment as you normally would.
On the Checkout screen, enter your customers email address. Select the envelope button to send them a copy of their receipt via email. You can enter as many email addresses in succession as you would like to send the receipt to multiple email addresses.
Your customer will then receive an email with a copy of the receipt.
