SignTime, developed by SignTime Inc. in Tokyo, is a Japanese e-signature and contract management platform designed for international business use. It handles multiple file formats (PDF, Word, Excel, and PowerPoint), reusable templates, and signing via email or SMS.

SignTime adds verification steps, access codes, and activity logs to every signature, meeting the requirements of Japan’s Electronic Signature Act. Optional long-term timestamps keep signed documents verifiable for years after signing.

A free plan with limited monthly sends is available, letting teams try the platform before upgrading. All plans include unlimited users and sending.

The platform includes internal approval workflows, multi-party signing, bulk sending via CSV, renewal alerts, custom branding, and API connections including a built-in Salesforce connector.

SignTime supports both Japanese and English across signing screens, notification emails, and the admin dashboard, making it well suited for bilingual and international teams.
