Mitsumo Co., Ltd. (Headquarters: Chuo-ku, Tokyo, Representative Director: Ayako Ishikawa) has started offering an "Electronic Signature Option" for its on-site SaaS "Proone." This option integrates document creation for estimates, orders, and invoices, internal approval, and agreement formation with business partners (electronic signatures). By completing document work, approvals, and signatures—which traditionally tend to be scattered across paper or multiple tools—within Proone, the option aims to reduce the burden of transcription, rework, and waiting for approvals/collections, thereby supporting improvements in operational speed and accuracy.
