Invoicing

You can conveniently manage your company’s electricity invoices through online or e-invoicing. You will receive a collective invoice for multiple sites instead of individual invoices. 

If you have any questions regarding invoice payment, postponement of the due date, collection or the payment period, please contact our payment helpline.

Below you will find more detailed information about the various invoicing and contact methods related to corporate invoicing, as well as Oomi Solar’s invoicing details.

E-invoice

An e-invoice is a secure method developed by banks for receiving and paying invoices. You can sign up for e-invoicing after you receive your first invoice. On the invoice, you will find the information you need for the e-invoice agreement: the customer number and the reference number of the most recent invoice. Once you have signed up for e-invoicing, you will receive your invoices directly to your online bank. You can also find your invoices in MyRopo.

Collective invoice

If your company has ordered multiple services from Oomi Solar, they can all be itemised and invoiced on a single invoice.

Electronic payment reminder

We have adopted an electronic payment reminder solution. If your company has been receiving its invoices electronically and fails to pay an invoice by the due date, you will receive a payment reminder in the same way as the original invoice.

The service works with all online invoicing operators. For e-invoices, the service is currently available to customers of Danske Bank, OP, S-Pankki and Ålandsbanken. The service will be expanded to cover customers of other banks as the banks adopt the electronic reminder solution.
