What It Is

Modusign（모두싸인）is a Korean electronic signature and e-contract platform. According to its own materials, it serves 330,000 corporate and institutional members and 10 million users, and has processed more than 50 million signatures and documents. It is positioned not just as an online signing tool, but as a broader platform covering contract preparation, signing, delivery, archiving, data extraction, and AI contract management through Cabinet.

Core Capabilities

The basic workflow lets users upload HWP, DOCX, PDF, XLSX, image files, and more; place fields such as signatures, text, dates, and dropdowns; send signing requests via email, KakaoTalk, or LMS; and track progress in real time. More advanced scenarios are supported as well, including link-based signing, in-person signing, bulk sending, scheduled sending, multi-party signing, templates, 100+ legal forms, contract reminders, tag-based search, and dashboards. On the team side, it offers shared workspaces, member permissions, internal approvals, and document sharing, making it suitable for collaboration across HR, legal, sales, procurement, and other departments.

Integrations, Security, and Deployment

Its enterprise capabilities are relatively comprehensive. The API can connect with ERP, HRM, CRM, groupware, and a company’s own web/app systems, with support for webhooks and data callbacks. It also mentions support for around 20 programming languages, including Java, Python, and Node. Third-party integrations include Slack, Google Drive, Google Sheets, Notion, Zapier, Salesforce, and others, though some are still listed as planned. On security, it highlights ISO, ISMS-P, CSAP, audit-trail certificates, tamper-proof hashes, IP restrictions, 2FA, SSO, audit logs, and dedicated network communication. Deployment options include cloud service, API integration, and On-Premise deployment, covering scenarios involving highly sensitive data.

Pricing, Pros, and Cons

Public plans start from KRW 9,900/month for Personal, KRW 55,000/month for Team, and KRW 88,000/month for Team Pro. Annual billing comes with a clear discount, and Team Pro can be tiered by annual request volume from 360 to 1,000. Its strengths include strong localized signing workflows, relatively transparent pricing, solid security/compliance credentials, and robust API capabilities. The downsides are that it is clearly oriented toward the Korean market, entry-level plan quotas are limited, and API access, on-premise deployment, and security packages require custom quotes.

Who It’s For and Access from China

Modusign is best suited to organizations operating in Korea that need KakaoTalk-based signing, compatibility with Korea’s electronic signature legal environment, and public-sector or enterprise compliance. Chinese users should note that the available materials do not clarify direct network access from China, RMB/international card payments, or the legal validity of its electronic signatures under Chinese law. Its accessibility from China is unknown. If the primary use case is in mainland China, local alternatives such as e签宝, 上上签, and 法大大 may be worth comparing.
