Attach file to invoice

I have a client looking at using eShop to sell gift certificates. They want a PDF to be attached to the invoice email to save having to manually send the certificate after payment is received.

I see attachments in the product setup, but that's to display downloadable items on the frontend. Is there a way to attach a file to the invoice? If not, please consider this as a wishlist item.

Thanks.

Hello Ian,

I am sorry but there is no option to attach the attachment files to invoice now.

Sincerely, Giang
