When sending invoices to multiple customers at once, Twikey automatically applies each customer’s configured delivery method — whether that is email, letter, or Peppol. There is no need to manually filter or split invoices by channel beforehand. This is particularly efficient when working with a mixed customer base that requires different delivery methods.
