This places a major burden on both parties, including sorting the necessary documents, checking to see if they are filled in, confirming documents, purchasing stamps, affixing seals, and mailing.

This service automatically sorts and produces the necessary documents for real estate purchasing contracts (which differ by customer), automatically fills in the required information, and centrally manages statuses online. Further, “Musubell” is linked with the API of’s “CloudSign” to make the contract process easier for both sellers and buyers by digitalizing the entire purchasing contract, which eliminates the need for tasks such as signing, stamping, and mailing.
