Contact and invoice questions

When will support reply?

Most requests are reviewed within 1-2 business days. Include a payment when your question concerns a transaction.

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.
