Invoices sent by the city

The City of Oulu offers its customers and partners an electronic approach both for outgoing and receiving invoices. 

Corporate customers

The City of Oulu automatically updates the postal addresses and e-invoice addresses of corporate customers. Electronic invoice (e-invoice) addresses are obtained from the e-invoice address list by TIEKE. The automatic e-invoice address updating service always updates e-invoice addresses according to the legal customer's business identity code (contracting party, delivery customer). Corporate customers must maintain the e-invoice addresses linked to their business ID themselves in the e-invoice address list at

The postal addresses of the companies used on the City of Oulu invoices come from Business Information System YTJ's register with an automatic update, so companies should also update YTJ’s postal addresses if necessary. 

At the beginning of 2021, the City of Oulu's sales invoicing adopted the 3.0 format in accordance with the e-Invoicing Act. After this, the City's invoices meet the invoicing requirements for value added tax in accordance with the Tax Administration's guidelines. In addition, invoices receive an order number, contract number or construction site information if the customer has provided such information. 


Private customers
The City of Oulu offers the possibility of e-invoicing for consumers. Customers are hoped to make e-invoice agreements for all invoices sent by the City of Oulu. An e-invoice is an electronic invoice that a customer receives directly to their own online bank after having made an e-invoice agreement at their own online bank. 

E-invoicing is convenient, effortless, safe and fast. The consumer gets access to the e-invoice quickly and pays the invoice with only a few clicks of a button. An e-invoice customer does not need to type any account numbers or invoice reference number themselves, approving the information is all it takes. There will be no typing errors and you can get rid of paper invoices. Invoices are stored in an electronic archive. The city delivers invoices safely to banks' online service, and invoices can be paid anywhere and anytime, as long as there is an internet connection. The e-invoice sent by the City of Oulu is displayed in the online bank as a normal invoice that looks like a paper invoice. 

Make an e-invoice agreement in your own online bank. By selecting the City of Oulu as the invoice subject, you will receive the following invoices sent by the city to your online bank: 

  • Education and Cultural Services: early childhood and education (daycare), morning and afternoon club activities, Conservatory, Art School, Oulu-opisto, matriculation examination, Luuppi, library, Oulu Sinfonia, Oulu Music Centre, bookings of sports facilities and gyms, basic education and municipal influencing and cooperation 
  • Urban and Environmental Services: rents, drainage water, excavation permits, public transportation, streets and traffic, city zoning, land and surveying

In addition, the City of Oulu still has the following e-invoice subjects for private customers: 

  • Property and Facilities Management Services Oulu Rents
  • The City of Oulu Facilities Rents Y and Y services
  • The City of Oulu WATER BILLING

Further instructions on how to implement e-invoice can be received from your own online bank and the bank's customer service. 

Direct payment

The City of Oulu offers a possibility of direct payment for water bills by Oulu Waterworks that do not have online banking at their use. If a customer wants to use direct payment, an agreement is made at the customer service of their own bank. Presenting a previous invoice is required. 

The City of Oulu delivers the invoice information well in advance before the due date by mail and simultaneously sends the invoice payment information directly to the customer's bank. The invoice contains information that the bank will pay the bill automatically from the customer's account on the due date. 

If you make an e-invoice agreement for a direct payment currently in force, please remember to terminate the direct payment agreement at your bank's customer service. 

With any questions related to invoicing, please contact the unit sending the invoice first. The details of the invoicing unit can be found on the invoice.
