Trusted by industry leaders
Throughout our history, we have worked with some of the largest accounting organisations in Finland. Thanks to the agile customizability of Koho PSA, the software fist both large teams and smaller expert companies alike. Both Finago and Taloushallintoliitto sell and distribute a service created by Koho PSA.
In co-operation with Finago, Koho PSA has developed an easy to use white-label ERP system for accounting firms. Procountor accounting firms use our Procountor ERP system, and it keeps track of the most important workflows and tasks.
Together with Taloushallintoliitto (Association of Finnish Accounting Firms), we have developed a cloud-based service for accounting firms used in contract management and to generate TAL 2018 contract documents. The software allows accounting firms to create framework contracts. It is free of charge for all member companies of the association.
