Astonishing accounting 

Focus On Your Profession – We’ll Take Care of Your Accounting

Accountancy firm authorised by the Financial Management Association

MST-Yhtiöt Oy is a Financial Management Association authorized accounting firm, founded in 2003. We serve businesses of all sizes across Finland from our offices in Kerava and Porvoo. Working with us is straightforward and transparent. 

Although we carry out our work with diamond-like precision, we don’t aim to be stiff or stuck in routines. You will always be served personally and individually, and we often receive praise for our quick responsiveness and flexibility. We continuously develop our operations and expertise to offer you the best possible service, while positioning ourselves as an innovative leader and forerunner in our field. 

Accounting services tailored to your needs 

We offer all traditional accounting services, from invoicing and payroll to financial statements and tax returns. We also provide modern electronic accounting services. In addition to basic services, we have specialised expertise in areas such as real estate development, company transformations, mergers and acquisitions. 

Our prices are competitive (starting from €38.50/month) and transparent. Thanks to our decades of experience, skilled and trained staff, and personalized service, you can trust your accounting with us and focus on what you do best. 

I have been working with MST-Yhtiöt for five months now, and I could never have imagined that dealing with an accounting firm could be like this. Whenever I’ve needed it, I’ve received exceptionally fast, friendly, and professional service. I can no longer imagine going back to the old way of working with the “big” accounting firms, where the service feels mechanical.
