Ongoing experiments

On this page, we collect the ongoing experiments of the Real Time Economy Project.

When the experiment has ended, we will report on its results and move its description to the conducted experiments page.

  • Transfer and utilization of electronic invoices

    This Proof-of-Concept study tests the technologies involved in the transfer of electronic invoice data from an operator to the users of the data. For a feasible application it is necessary to be able to convert this type of data into a standard structured format. This would enable the use of such data for national statistics as well as for the automated assignation of VAT returns.

    Another issue to be tested is whether the State Treasury can act as a data collector and intermediary for different agencies, for example the Statistics Finland or the Tax Administration, to the extent of and in accordance with their access to information rights.

    Developing new information sharing channels like this is part of the ecosystem work of the Finnish Real Time Economy -program.


    Tax Administration, Statistics Finland, State Treasury. We are looking for e-invoicing operators as partners during March 2023.


    The trial will begin in February and is expected to be completed by the summer.

    The aim is to:

    • to validate the process of transferring electronic invoices via the API from the operator to the State Treasury
    • find out whether the collection of data from electronic invoices via the API is feasible for Statistics Finland and the Tax Administration
    • find out the usability of the information obtained from electronic invoices in official reporting
    • find out the usability of real business data, i.e., information obtained from actual electronic invoices, in the automation of VAT returns declaration and statistical reporting
    • successfully produce a VAT return and describe the things that are challenging to produce
    • describe the current implementation of information acquisition for use by different authorities and the impact of the changes

  • Simplified reporting by means of a long profit and loss statement

    In the experiment, we want to verify how the so-called long profit and loss statement presented at the level of general ledger accounts would serve the needs of various authorities and other information users. The focus of the experiment is the study of the information needed for income tax reporting and statistics. The standardization of the information content is based on the content of the Liikekirjuri account chart.

    Another starting point in the experiment is a standard way of presenting information, which would enable its automated utilization in different systems. This experiment tests the XBRL GL specification as a file format.


    Two system providers, Accountor Finago Oy and Mediamaestro Oy, have been elected to conduct the experiment. Kirjurituote will be the collaborating partner. The standardization of the information content is based on their Liikekirjuri™-account chart .


    11/2022 – 09/2023. 


    • to show that the so-called “long result and balance sheet” standardized in terms of quantity and information content is sufficient to cover various official reports (e.g. income tax return information)
    • to verify that the account scheme used by customers works on the basis of official reporting
    • to make sure that customers have the ability to produce possible necessary mappings between account schemes if there is a deviation from the standard account scheme
    • to make sure that the software houses are able to produce the data out of the system in a shared format
    • to understand how well the configurations being tested work in practice, and how much work the proposed procedure causes for client companies and software houses, and correspondingly how much benefit can be achieved from it.

    Experimental work in practice

    Ledger balances are produced in XBRL GL format according to the example file. The material is synthetic data and the experimental platform is MiniSuomi. Synthetic material is completely artificial, it is not based on real data.

    In the first phase of the experiment, synthetic data was produced, which is openly available in the MiniSuomi service. In the second phase of the experiment, it is also intended to produce datasets of real companies that the agencies can examine internally.

  • Use of e-receipt information

    Combining card purchase receipts with card invoices in the purchase invoice system.

    In the experiment, a model report is also created for those purchase lines with card invoices for which eReceipts have not been received. This makes it easier to check the card invoice in the purchase invoice system.

    The scheme is linked to the EUDI wallet consortium pilot.

    A Proof-of-Concept (PoC) has been implemented in early December 2022

    • How can a Swedish company request basic information from a Finnish company and vice versa
    • Where the information is located and who should hand it over
    • Functional use cases, demonstrations of the technical solution and presentation of the results

  • eAddress experiment in digital wallet and trust networks

    The company’s digital identity, wallets and other new technologies must be tried out in order to gain real experiences of using them to support decision-making.

    In the joint process workshops, the use cases that will be worked on in the technical experiment are defined and selected together with the stakeholders.

    The technical experiment is carried out in the MiniSuomi environment. The technical implementation of a wallet and trust network will be created in MiniSuomi, where together with stakeholders, the identity of companies in using eReceipts, procurement notices and other digital documents will be tested.

  • Construction industry PoC with Peppol procurement messages

    The goals of the PoC (Proof-of-Concept) are to verify the functionality of the Peppol network in the construction and construction product industry, including the use of standardized product information, and to evaluate the effects of electronic data exchange using the experience information obtained from the PoC. In connection with the PoC, a technical experiment will also be carried out, in which realistic procurement messages will be transmitted in the Peppol network. At the same time, the PoC promotes the project’s goal of introducing structured (Peppol) procurement messages.​

    ​PoC promotes the digitization of the construction and construction product industry, offering as a solution the opportunity to unify the business and product information of information transmission, reduce the costs of information processing and improve the quality of information. This enables, among other things, that the parties can send and receive structured messages based on standards.​​

    ​When it becomes common, the solution will make procurement-related transportation and other logistical processing more efficient, as well as enable the reduction of CO2 emissions as the predictability of operations increases.​

    ​PoC applies to companies working as buyers in the construction industry and as suppliers in the construction product industry. It also has an impact on logistics companies participating in product supply chains and on research that develops supply chains in the construction industry, for example Building 2030 consortium projects, Peppol service providers and the State Treasury as Peppol authority.​​

    The purpose of the PoC is to produce a practical example of what the use and transmission of electronic business information means in the construction industry and construction product industry. Based on the results, the construction industry ecosystem is able to plan and implement actions leading to the production use of Peppol procurement messages.

    The results of the PoC will be announced in open webinars (or similar) and in their materials.​​


    The PoC is implemented in the MiniSuomi environment in cooperation with Fira Rakennus Oy, DBE Core Oy, Maventa Oy and the Real Time Economy project.​​


    Start in January-February 2023

  • From eInvoicing to warehouse accounting

    The purpose of the experiment is to test how the flow of product and batch information as part of an eInvoice could facilitate the work of agricultural and small entrepreneurs and stakeholders, such as the supervisory authority, and lighten reporting. In the experiment, product and batch information will be added to the eInvoice and mobile machine language reading will be tested, so that the information could be used in warehouse and block registrations as well as in the food producer’s traceability reporting. This would make the farmer’s everyday life easier, since the records could be made where the work is done, i.e. in the barn and in the fields, for example. The experiment produces instructions for adding product batch information to the European eInvoicing format and demonstrates the benefits of the solution for the industry and its stakeholders, for example in product traceability reporting.


    The experiment is implemented as a MiniSuomi implementation in cooperation with KomKom Ky and the software company Suonentieto Oy.


    Start in February 2023
