A: We created an "Upsell Plugin Invoice Extension" which you can install and enable to automatically create invoices for your customers. You can then use the emails within the Upsell Plugin to include a link for the customer to download the invoice.

It also creates an invoice column in your orders so you can click and download the invoice if you need it for your records / want to send it to a customer directly.

We currently don't connect with iDeal or SEPA, but we plan to enable this via our Stripe integration in the near future.
