# I have associated a payment gateway to an invoice. My customer is unable to find the option to pay for it. What should I do?

When you email an invoice to your customer, the invoice PDF is attached to it and a link to view the invoice **(“Click to view Invoice”)** will be available in the email content.

When your customer clicks on this hyperlink it will open the invoice in a new tab and will have a **Pay Now** button. Once the customer clicks on the **Pay Now** button, the list of payment options enabled for this invoice will be listed.

The customer can choose the desired payment gateway and then click **Proceed to Payment** which will take him/her to the payment gateway.
