We have major spare devices at our cost
If hardware devices, especially the ones used in core service level, fails, it can mean major business disruption. Purchase of new equipment can take time. In order to shorten the downtime, we have major networking and server hardware devices as spare so that in case of failure, we can replace it immediately and can restore customer's business operations in timely manner.

Various important data, such as specifications and user data, are documented
We think documentation is important. We create documents describing all the important information, such as user login data of each PC, warranty record, network design and specifications, and configurations. Many Japanese IT service providers tend to not share such information, but we do because we think that business continuity of our customers is more important than risking our customers because of single dependency. We share all those information with the customer so that customers are not restricted with us and can make changes of its devices and even are free to move to other service providers.

Preferential treatment for Active Directory
We have preferential price plans for customers using or planning to use Microsoft Active Directory.
