Personable, reliable, efficient.
I realised I needed support with managing my taxes when I started my business and 2 new jobs. Tax service at Otani Accounting Office gave me a good insight into bookkeeping and managing my finances overall. Besides, personable communication from the first email to the virtual (Skype video) interview was a great add-on. Plus the fact communication was
clear and easy to understand, and all in English language.”
