Tutkihankintoja.fi is a brand new service that gives transparency on Finnish government procurement. Web service has information about what the state buys and which public funds are used. You can explore purchases, for example, by organization or category. Dataset should be soon available on Finnish open data site avoindata.fi but I fetched all invoices using R from Ministry of the Interior and created an interactive Tableau application for better overview. Colors are adjusted to match with publications from Ministry of the Interior.
This dashboard has filters for date period and search field for vendor’s name and business id. I have used dashboard actions to filter from top level down to vendor level.
