Policy for Managing the Invoice System

Kumagai Gumi has established a code of conduct for the management of the invoice system, which it implemented in October 2023. This code is detailed below, and it must be followed by all officers and employees.

  1. Kumagai Gumi requests that businesses register as qualified invoice issuers. It shall not compel them to do so.
  2. Kumagai Gumi shall not unilaterally terminate transactions with businesses or refuse to pay all or part of the amount equivalent to the consumption tax to them because they are not registered as qualified invoice issuers.
  3. If a tax-exempt business transitions to a taxable business after registering as a qualified invoice issuer, Kumagai Gumi shall not unilaterally decide to keep the unit prices the same without negotiating prices. This is applicable when a taxable business requests that Kumagai Gumi will review unit prices that were established when it was still a tax-exempt business.
