We are improving how invoices are transferred to Amili Perintä, Visma Amili’s reminder and debt collection service for Finnish companies. Both the Maventa user interface and the API are getting an updated transfer experience that captures everything Visma Amili needs to start collection straight away — full debtor details, any co-debtors, what the assignment concerns, and the assignment type (rental, B2C, or B2B).
Why this change
Today, many invoices are transferred to Amili Perintä without all the information needed to start the collection process. That means Visma Amili has to research the missing details or contact the sender, which delays the process and adds manual work on both sides. By capturing the right information up front, cases move forward without unnecessary back-and-forth and collection gets going faster.
What this means for you
- Faster start to the collection process for every new case
- Fewer follow-up requests for missing information
- Clearer handling of rental, B2C, and B2B assignments thanks to the assignment type
- Better support for joint liability cases through structured co-debtor information
In the Maventa UI
A new form for transferring invoices to Amili Perintä is now available from the sent invoice details. You can use either the current form or the new form until 1 September 2026, after which only the new form is available.
What you should do now:
- Start using the new form for every new invoice transfer — the earlier you switch, the smoother the transition
- Make sure the people transferring invoices have access to the additional details the new form asks for
- Update any internal guides, templates, or training material before 1 September 2026
For API integrators
A new v2 endpoint, POST /v2/invoices/{id}/assignment/amili, replaces the current v1 endpoint. The v1 endpoint is deprecated and will be shut down in Summer 2027. Until then, both versions run in parallel. The exact shutdown date will be confirmed at the beginning of 2027 — we recommend starting the migration as early as possible. See the integration guide for parameters and a request body example.
Timeline
