Invoices by email

If sending an e-invoice is not possible, invoices should be sent by email to invoices-0115535-4@kollektorinvoice.com.

Please note: invoices must be in PDF format, one invoice per PDF attachment. The body of the message is not read — invoice attachments are scanned automatically.

Paper invoices

If sending invoices by email is not possible either, paper invoices should be sent to Oy SEK Ab, 0115535-4, PL 8, 80020 Kollektor Scan.

Please note: on paper invoices the address field must carry the Kollektor Scan address, not SEK’s postal address, because invoices sent by post are scanned automatically.
