■ Background of the Service Launch

Due to the decline in the working-age population, small and medium-sized enterprises, in particular, are facing a severe labor shortage.

The difficulty in recruiting and training accounting and HR personnel responsible for back-office operations is a major burden for business owners, and the low productivity of back-office operations has long been considered an issue for Japanese companies.

Our group has supported the management of small and medium-sized enterprises for many years as tax accountants. In doing so, we have heard many challenges such as the following:

• Difficult to recruit accounting and HR personnel, and even when hired, they do not stay

• Unable to educate and train back-office personnel

• Operations become dependent on individual skills, and business stalls when the person in charge resigns

• Want to promote DX, but lack in-house know-how

• Want to focus on the core business, but back-office operations take up too much time

On the other hand, since the COVID-19 pandemic, diverse working styles such as remote work are spreading, but the reality is that many specialized personnel have left their jobs for reasons such as childcare and nursing care, and they are expected to play a part in resolving corporate labor shortages.

Our company will establish an environment where remote workers living in regional areas can work, and by collaborating with tax accountant corporations and labor and social security attorney corporations, we will utilize the expertise and DX know-how cultivated in professional offices to launch a new back-office business process outsourcing business.
