Customer Feedback
Since requesting management accounting support, our business figures have become much clearer. We can now take swift action against unprofitable stores, which has been a tremendous help. (Food Manufacturing & Retail Industry, Saitama Prefecture, 70s, Owner A.S.)
I received support with my grant application. They grasped my business quickly and communicated in a way that understood my intentions, making the process stress-free. (E-commerce business, Tokyo, 30s, Owner U.M.)
It’s rare to find a tax accountant who can support business planning. Their deep understanding of new businesses makes them truly reliable. (Electricity Retail Business, Tokyo, 30s, Owner T.S.)
Not only does he discuss tax matters, but he also consistently presents new information and insights about our company’s management and engages in discussions with us. (Apparel Wholesaler, Tokyo, 40s, Owner H.R.)
When our cash flow is tight, I find it extremely helpful to receive support in preparing materials and conducting meetings when consulting with financial institutions about loans. (Construction Industry, Tokyo, 40s, Business Owner N.K.)
When our predecessor in accounting left, they assisted with the inventory of operations and systemization. I’m satisfied that we achieved operational transparency and efficiency in a short period.
