Maventa is currently building a new signatory-check flow for Finnish company onboarding. When the flow goes live, registering a Finnish company through the Maventa UI will verify the signer’s signing authority against the Finnish business register and require the signer to sign a Maventa Terms of Service document via Visma Sign — replacing the current admin-driven Visma Sign step in the registration wizard. The flow is still in development, but on the Maventa stage environment the underlying mocks are now active by default so partners and integrators can preview the full signee experience today. See Mock mode for Finnish companies registered over the UI (stage) in the integration guide for the step-by-step flow.
This flow is still in development and is not yet feature-complete. The mock-mode preview is available on the Maventa stage environment only, and the upcoming signatory-check flow itself will apply only to Finnish companies registered through the Maventa UI. API-driven authorization via POST /v1/company/authorization and POST /v1/companies/authorizations is not affected and continues to work as it does today.
Why we are building this
Opening a Maventa account for a Finnish company requires a signature from someone with legal signing authority — a person listed as a nimenkirjoitusoikeus-holder in the Finnish business register. The new flow verifies that authority against the business register before the signatory is routed to Visma Sign, so the signature is provably backed by the register at the moment it is taken.
What is now active on stage
Both the signing-authority lookup against the Finnish business register and the Visma Sign signing service run in mock mode by default on stage. To register a Finnish company on stage and walk through the new signing flow, you need one of the test identity-code paths below:
| Personal identity codes | Authority type |
|---|---|
010191-0031 |
Sole signing rights (signs alone) |
010191-0042 + 020292-0132
|
Joint signing rights (both signers required) |
010191-0053 |
No signing rights (rejected at the authority check) |
No real bank authentication, no real personal identity codes, no Visma Sign service login — the mock simulates the whole chain.
How to recognise mock mode
A bright amber STAGE MOCK MODE banner appears at the top of every page in the signee flow and on the admin wizard’s signatory-check views. The banner reads:
STAGE MOCK MODE — This is a test environment. Personal identity codes and signatures are simulated. No real data is processed.
If you see the banner, you are exercising the mock chain. If the banner is absent, you are either on the real path (mocks toggled off via Maventa admin) or in production, where the banner is never shown.
Timeline
Maventa will announce when the signatory-check flow goes live for the first real Finnish customer in a separate changelog post. Until then, treat the stage mock as a preview surface for evaluating the user experience.
