Template for Finnish print service

By default, invoices sent through the print service use a Maventa-generated invoice template. This template is optimised for efficient processing, complies with all technical requirements, and is designed to fit the envelopes used by the printing service provider. Customers can personalise this template by adding their company logo.

Example of Maventa template for Finnish prints.

As an alternative, customers may use their own invoice image for all printed invoices or on a per-invoice basis. When using a custom image, Maventa automatically adds a cover sheet with the recipient’s address details. This ensures proper alignment with the envelope window. The cover sheet is counted as an extra page and billed accordingly.

Finnish companies also have the option to exclude the cover sheet from prints. In that case, the sender is responsible for ensuring the invoice image meets the layout rules, including the position requirements for the receiver’s address details so that they fit the envelopes used in Finland. Contact support to confirm your layout and enable this setting.

If you use your own invoice image without a cover sheet, familiarise yourself with the PDF layout rules by Posti. In addition to Posti as the mail distributor, Jakeluyhtiö Suomi Oy (JYS) has a few additions to the Posti rules. The difference is the tracking barcodes they print on the invoice image — see the JYS rules merged with the Posti ones.

Colour printing

Customers can choose whether all invoice images should be printed in colour or in black & white (via API or UI). By default, invoices in Finland are printed in black & white. If colour printing is enabled, it is billed based on the total number of pages in the invoice, regardless of how many pages actually contain colour.

In addition to the company-level setting, the colour option can also be defined for individual invoices when sending via the API.

To enable colour printing for all invoices from a company account, use PATCH /v1/company/setting. In the send_invoice_print block, set the parameter color_scheme to COLORED. To revert to black & white, set color_scheme to BLACK_AND_WHITE.

Attachments

Printing of attachments is disabled by default, with the following rules:

Up to 3 separate attachments are allowed (maximum of 4 files including the invoice image).
Only PDF format is allowed.
Maximum size per attachment: 50 MB.
Total maximum number of pages: 110.

If these limits are exceeded, all attachments will be discarded. The sender will be notified by email, but the invoice image itself will still be printed.

There is an extra charge per page printed.

Envelope sizes

The Finnish printing service uses two envelope sizes:

For invoices of up to 9 sheets, a smaller C5 envelope is used.
For invoices exceeding 9 sheets, a larger and more expensive C4 envelope is used.

Since all invoices are printed double-sided, an invoice must have more than 18 pages before it exceeds 9 sheets and requires the C4 envelope.

Note: If the sender’s own invoice image is used with a cover sheet, the cover sheet added by Maventa is counted as one page.

Delivery schedules

Invoices sent to Maventa before 24:00 are printed, processed, and enveloped overnight and handed over to the mail distributor the following morning. Production does not take place during weekends and holidays.

Delivery depends on the selected letter class. For Finnish companies sending domestic letters, there are two options: Priority and Economy (default). The letter class can be adjusted via API or UI.

For Finnish domestic letters, the practical difference between Priority and Economy is often minimal due to regional delivery schedules, which can have more impact on when the recipient receives the invoice than the selected letter class. Priority may still provide benefits for business-to-business invoices, but for consumer invoices, the recipient’s delivery schedule is usually the main factor.

For international letters, only Priority is available.

To change the letter class use PATCH /v1/company/setting method and set send_invoice_print[letter_class] to PRIORITY or ECONOMY.
To define the letter class for a specific invoice use POST /v1/invoices method and set print_settings[letter_class] to economy or priority.

OmaPosti

OmaPosti is an application that allows consumers to receive their letters electronically instead of on paper. When a consumer invoice goes to print, Maventa’s print service provider performs a lookup against the OmaPosti consumer registry. If the consumer has an active OmaPosti account and has not opted out of receiving digital letters from the sender (based on the Maventa account’s OVT code), the invoice is redirected to the consumer’s OmaPosti account instead of being printed.

To determine whether a consumer has an OmaPosti account, a combination of consumer name and postal address or social security number is used for identification. While an SSN can be used as an identifier, avoid including such sensitive information on invoices.

The sender can also exclude an invoice from the OmaPosti route:

To prevent using OmaPosti route for an invoice use POST /v1/invoices method and set print_settings[prevent_digital_post] to true.

Automatic e-instruction page

When enabled, every invoice printed using Maventa’s PDF template is automatically accompanied by an instruction page, guiding your customer on how to receive invoices electronically instead of on paper. This instruction page is provided at no extra cost.

To enable the automatic e-instruction page, use the PATCH /v1/company/setting method. Under send_invoice_print block set the parameter marketing_page to true.
