Contact and invoice questions

Which payments can receive an invoice?
Completed, non-refunded Stripe, Creem, and Alipay payments with a positive amount are eligible.
Can I change an invoice after it is issued?
No. The first issue creates an immutable payment, seller, and buyer snapshot; later downloads return that same invoice.
