The invoice system will start in October 2023. Although each company is investigating the system and considering its policy, there are not many opportunities to find out how other companies are progressing and what their policies are. Therefore, in this report, we conducted our own questionnaire survey of companies in various industries and business categories, and summarized the actual status of each company's response to the system, including the progress of system support and policies for dealing with business partners. We hope that this report will be of some help to those in charge of accounting and information system departments who are considering the guidelines for invoice systems.
