会社概要Company profile
The company boasts top-class market shares for many cloud services, including the familiar "RakuRaku Settlement" service advertised in TV commercials.

To date, the cloud-based expense settlement system "RakuRaku Settlement" has been adopted by over 15,000 companies, and the electronic invoice issuance system "RakuRaku Meisyo" has been adopted by over 8,000 companies, bringing about major changes to expense settlement operations in Japan.
Due to legal reforms such as the invoice system and the Electronic Bookkeeping Act, demand for our services is expected to increase in the future.
