■ Background of Service Launch

Due to the declining working-age population, SMEs, in particular, are facing a severe labor shortage.

Difficulty in recruiting and training accounting and labor personnel for back-office operations has become a significant burden for business owners, and the low productivity of back-office operations has long been a challenge for Japanese companies.

Our group, as tax accountants, has supported the management of SMEs for many years. During this time, we have heard numerous challenges like the following:

• Difficulty in recruiting accounting and labor personnel, and high turnover even if hired

• Inability to educate and train back-office personnel

• Tasks become person-dependent, and operations halt when the 담당者 leaves

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

• Want to focus on core business, but back-office tasks consume time

On the other hand, since the COVID-19 pandemic, diverse working styles, including remote work, have been spreading. However, many specialized personnel who left their jobs due to childcare or nursing care reasons remain unemployed, and they are expected to play a role in resolving corporate labor shortages.

Our company has established an environment where remote workers residing in rural areas can also work, and by collaborating with a tax accountant firm and a social insurance labor consultant firm, we utilize the expertise and DX know-how cultivated in professional offices to launch a new back-office business process outsourcing service.
