Invoicing in the Helen Group
We will process only e-invoices as of 1 April 2020 due to the EU directive on e-invoicing and the Electronic Invoicing Act (241/2019). If you still have not started using e-invoicing, you can send e-invoices to us via the free Basware Portal service. Our e-invoicing addresses and instructions for using Basware Portal are available at the end of this page.
Use of reference numbers
A reference number is needed in the payment of all invoices. The reference number is the order or contract number provided in connection with the order (starting with PO, PP or H). The reference number must also be added to the e-invoice data.
Invoices arriving without a reference number will be returned to the sender.
Helen Group payment terms
The general Helen Group payment terms are 30 days net (net 30). Please note this term of payment when invoicing Helen Group companies, unless otherwise agreed in a mutual contract with you.

Basware Portal – send e-invoices for free
If you still have not started using e-invoicing, you can send e-invoices through the Basware Supplier Portal service. This requires an Internet connection and registration in the service. The service is free of charge. When you register in the supplier portal, you can send e-invoices to Helen Group companies and also to over 10,000 other organisations.
The service is aimed especially at small suppliers who do not have an invoicing system enabling e-invoicing. Banks, e-invoice operators and accountancy firms also offer several alternative methods for e-invoicing.
