Billing Information

Dear Partner,

We have transitioned to electronic billing and kindly request that you submit invoices primarily in electronic format. If your company is unable to send e-invoices or email invoices, you may send paper invoices to our scanning service address. Please note that we do not accept invoices at our physical office.

1. E-Invoices

Kalajoen Rakennus Oy, Business ID: 2828857-9

E-invoice address: 003728288579

Operator: Maventa (003721291126)

Intermediary code when sending from a bank network: DABAFIHH*


*Please use this intermediary code if your e-invoicing software does not allow direct transmission to Maventa's intermediary code.


2. Invoice Receipt via Email to Scanning Service

We kindly request that you use this email address exclusively for sending invoices. Invoices should be sent as PDF attachments to the email, and any invoice attachments should be included within the same file as the invoice itself.

Email invoice address:

• You may send multiple invoices in a single email message, as long as each invoice is a separate attachment with a unique name.
• The maximum size for a single email is 5MB.
• PDF files should be genuine PDF documents (PDF version 1.3 or newer).
• PDF files must not be locked or password-protected.
• The document's physical dimensions should not exceed 210 x 297 mm.
• Allowed characters in attachment names are standard alphanumeric characters, a-z, A-Z, 0-


Please do not use special characters or spaces in attachment names.

3. Invoice Receipt via Postal Mail to Scanning Service

Please ensure that the recipient's details are complete both on the invoice itself and on the envelope to ensure quick and reliable delivery.

• Please send only invoice materials to the scanning address. These mail items are automatically processed into our company's accounts receivable, and other materials (e.g., receipts, corporate gifts, credit cards, and tickets) will not reach their intended recipients through this channel.
• Please use black ink on a white background for text whenever possible, as this provides the clearest result for recognizing invoice information.
• Do not use staples on invoices sent to the scanning service.
