… its domain complexity: we’ve managed to build a single universal system that calculates salaries for multiple countries, trade unions, company rules and regulations. We invented a custom functional DSL (VismaScript) for this, and now we don’t have to code any of these rules by hand - the business consultants are able to do that instead.

… its robustness under heavy workload: so far 19500 companies in micro market in Norway and Sweden, and 150 in SMB market in the Netherlands trust our product to calculate their payroll correctly, always. In the future we will also launch the product in Denmark and Finland and probably more countries.

… its smart architecture: a time machine which applies scripted rules (by country, organization, department, trade union) for any given moment in the past - for such things as calculations, reporting, integration services and much more.
