in Germany a merchant has to send customers by law information regarding the cancelation of subscriptions and a form to do so. "Widerrufsrecht"
Is there a way to attach additional Files e.g. *.pdf next to the Invoice? Which would solve the problem for me.
Sorry that we missed your query.
The option to attach files to the invoice is currently not available. We are working on this feature but don't have a fixed timeline at the moment. I'll reach out to you once the feature is out.
Please feel free to reach out to us for any further queries.
