PDF generated adfter order email has been send

[toontoet]

I'm testing the new 'method_banktransfer_invoice_immediately' option. What I experience is that the PDF Invoice is indeed created right after the order has been placed, in stead of the event default that is set to 'generate after payment'.

However: The client who is ordering doesn't receive the pdf invoice by mail automaticly. The pdf is generated after the order email has been send. Also: in the order email no bank-transfer details are shown.

It would be great to add an option to also send the invoice to the client by mail. because now, the only way to see the bank tranfser details is to open the order-details page.

This unfortunately will not be solvable without significant changes to pretix core. There's basically two methods to implement the "invoice immediately".

• Using the mechanism from the pretix core plugin API. This is what this plugin did until before BankTransfer: Generate invoice after payment if invoice_generate=paid (Z#23144775) #30 was merged. The downside is that the invoice will then be generated before execute_payment has been run, therefore the IBAN from mollie would not be on the invoice, which is bad.
• By just calling generate_invoice in execute_payment after the IBAN has been received from Mollie. This is what we did in BankTransfer: Generate invoice after payment if invoice_generate=paid (Z#23144775) #30, but unfortunately that means the invoice is generated after the invoice has been already sent via email.
