Should I need to send a PDF document if the invoice feature is already enabled in the payment widget?

I also have set up the Product List-->invoice option was enabled. Do I need both???

Hi Cathy,

Since you've already enabled your Invoice feature in the payment integration widget. You don't have to attach a PDF document if it's also an invoice made by you to avoid confusion, but if it's a summary of the submission or other PDF document, then you can send that to the user to give them additional information. Take note that it's up to you if you want to send them a PDF document or not.

Let us know if there’s anything else we can help you with.
