About Us

Kassavirtanen Oy is a Helsinki-based company founded in 2016 that offers affordable and hassle-free invoicing services as well as simplified entrepreneurship solutions. Our service allows you to invoice for your work without needing your own business ID, so our clients can focus on their work while we handle the paperwork.

Kassavirtanen takes care of invoicing, paperwork, insurance, and collections on your behalf. The service costs just 3% of the invoice amount excluding VAT, and there are no separate charges for sending invoices or debt collection.

We operate as part of Vastuu Groups Trusted Partner service and act as an agent for the Mutual Employment Pension Insurance Company Elo in matters related to YEL insurance. This ensures that our operations are transparent, reliable, and secure for our clients.

Kassavirtanen Oy primarily serves freelancers as well as those working on a project or seasonal basis across various industries. Our main areas of expertise include HR consulting, IT services, and financial management services for light entrepreneurs.

Kassavirtanen is a partner that makes invoicing a breeze—so you can focus on what you do best.
