# Finland — Finvoice, Peppol BIS & B2B-on-request

B2B-on-request since 2020 · B2G universal · Finvoice + Peppol — regulator: [Verohallinto (Finnish Tax Administration)](<https://www.vero.fi>). _Facts last refreshed: 2026-07-13._

Coverage model

Flowie operates a registered Peppol Access Point in this jurisdiction **directly** where we hold national accreditation, **or via a vetted local partner** registered with the in-country regulator where on-the-ground presence is required (KSeF, SDI intermediario, ZATCA service-provider, etc.). Either way, you call the same `POST /v1/documents/send`. 

## TL;DR

  * Finland operates a **B2B-on-request** regime: since April 2020, any buyer can demand a structured EN-16931 invoice and the seller must comply.
  * Domestic format historically: **Finvoice 3.0** (Finnish UBL-derived). Modern channels use **Peppol BIS 3.0** — both interoperable.
  * **B2G universal** since 2010 via Valtiokonttori (State Treasury) and the OPUS hub.
  * Flowie auto-translates between Finvoice and Peppol BIS.



## Deadlines

Date| Who| What  
---|---|---  
2010-12-01| Central government| Receive-only B2G mandate (Valtiokonttori).  
**2020-04-01**|  Domestic B2B| Buyer's right to request a structured invoice — de facto universal.  
2027-03-01| Possible full B2B mandate| EU ViDA-aligned; Finnish Tax Administration consultation underway.  
  
## Background

Finland's B2B-on-request rule (Laki sähköisestä laskutuksesta, 241/2019) is structurally similar to Estonia's: the seller can't refuse a buyer who asks for a structured invoice. Combined with very high adoption rates (Finland has had rich B2B e-invoicing since the early 2000s), the rule means structured-invoice volume is already over 80% of B2B in Finland.

## Format profile

  * **Peppol BIS 3.0** is the strategic format.
  * **Finvoice 3.0** remains widely used; bidirectionally mappable to BIS.
  * Finnish business ID (Y-tunnus, format `NNNNNNN-N`) on both parties.



## Required fields

  * seller.businessIdstring (Y-tunnus)required

Finnish business ID, e.g. `1234567-8`.

  * buyer.businessIdstringrequired for B2B

Same format.




## Public sector (B2G)

Hub| Peppol identifier scheme| Lookup  
---|---|---  
**Valtiokonttori OPUS**| `0037:FI-<y-tunnus>`| <https://www.valtiokonttori.fi>  
  
Public-sector recipients identified by the Y-tunnus over Peppol scheme `0037`.

## B2B reporting / clearance

_No central B2B reporting hub — pure transmission only._

## Error codes

_Generic Peppol BIS schematron error codes apply (`BR-*`, `EN16931-*`); no country-specific overlays._

## Testing in sandbox

What you want to test| How  
---|---  
Finnish B2B happy path| Y-tunnus `1234567-8` on both sides; sandbox returns 201.  
Force Finvoice rendering| Set `format: "finvoice"`.  
  
## FAQ

### Is Finvoice still required?

Not strictly — Peppol BIS satisfies the legal obligation. But many older Finnish ERPs only consume Finvoice; Flowie renders it on the way out automatically when the recipient prefers it.
