Holvi invoices can be sent also internationally! (only in Euro currency)
There are no specified international invoices in Holvi, regular Holvi invoices work perfectly, but you have to do one extra step. Add use the reference number-note into the invoice subject field, so that there will be no errors in the money transaction. Holvi recognises the reference number also from the message field. If the payment arrives without a reference number you can match it manually form the income category uncategorised.
