I WANT TO SEND AN INVOICE (REGISTRATION/MEMBERSHIP) BUT IT’S NOT ATTACHED TO THE PAYMENT NOTIFICATION

For instance that the invoice is not automatically attached on the notification, you would need to revisit the settings for the
Invoices and Billing.

Click the gear icon and go to Invoices and Billing, ensure that “Generate invoices for orders
automatically” is tick under Invoice and Receipt Settings and Custom Invoice and Receipt Configurations.

For invoice that was not generated you would need to manually send from the Membership profile > Finance details.
