If you send more than 500 invoices per month, option for you is to send the invoices directly from your invoicing system. It is possible with the help of Basware e-invoicing solution or any other e-invoice service provider. The same solution can be used for sending e-invoices to all other customers which can receive e-invoices.

Using XML or corresponding e-invoice file formats (e.g. TEAPPS, FINVOICE, SVEFAKTURA, OIO XML, PEPPOL BIS) provides fastest way to build up connection straight from invoicing system by taking into account country specific requirements.
