### Verify the Customer Record has an email address.

The Customer Record requires an email address. If there is no email address in the customer record, we will experience the checkout unavailable issue. If there is no email address, you can always add [test@paystand.com](mailto:test@paystand.cm).

### Verify if the Virtual Terminal is working correctly.

Verify if the virtual terminal is working. You can access the Virtual Terminal by selecting the **Pay with Paystand** button from the Invoice or Customer Record.

If it is not functioning correctly, you should create a [support ticket.](https://support.paystand.com/hc/en-us/requests/new?ticket_form_id=5053454753947)
