SignTime Prime is built on our core value: “Simple is Beautiful.” Guided by our belief that business tools should be easy and intuitive, we removed the need for complex setups or juggling multiple systems. From a single interface, you can manage e-signatures, scanner storage, approval workflows, and branded email delivery, everything required for a fully paperless workflow.
Optimized for SMBs and mid-market companies with 100–500 employees, Prime enables fast, efficient sales processes with a median contract completion time of 28 minutes via SMS. All security features are included by default, from two-factor authentication and audit logs to access controls and anti-phishing protection via corporate mail server integration, with no hidden costs.
Private branding allows you to unify contracts and notification emails under your corporate identity. No additional software is needed to manage e-signatures, scanner storage, approval workflows, and API integrations, all from one place.
Today, Prime is trusted across industries, from construction to hospitality to technology, with case studies available to explore how companies are achieving their digital transformation goals.
Contracts don't end with just a signature. The Prime Plan streamlines the entire process, from creation and approval to sending and storage, simultaneously achieving both speed and legal compliance.
SignTime’s e-signature Plan and Prime Plan are designed with small and medium-sized businesses in mind, offering unlimited users and smooth scalability as your organization grows.
For consultants, microbusinesses, and sole proprietors, the most efficient approach is to start with our Free Plan or Entry Plan, then upgrade as your needs evolve.

SignTime offers a robust e-signature solution that supports businesses of all sizes — from startups and mid-sized companies to large enterprises. Our standard “E-signature” plan is simple, affordable, and easy to adopt, while still providing all the essentials: legally compliant e-signatures, secure document storage, and complete audit trails.
For organizations looking to streamline more advanced workflows, the Prime Start plan adds long-term signature retention (scanner storage), SMS delivery, two-factor authentication (2FA), and signature delegation — enhancing both efficiency and security. The Prime plan goes further, offering API access and advanced group management, enabling tighter integration with internal systems and support for complex e-signature workflows.
For high-volume or large-scale use cases, the Enterprise plan offers even greater flexibility. It supports annual document volume pricing (ideal for seasonal variation), custom integrations beyond Salesforce and Google, and storage options such as “Sign and Shred” — where contracts are signed via SignTime but retained on your corporate storage platform.
For companies already using Salesforce, we offer SignTime for Salesforce, fully optimized for native use. We also provide a comprehensive Partner Program, supporting OEM, white-label rollout, internal deployment, and resale — whether within a group company or through external sales channels. All plans support unlimited users and full document tracking, and onboarding support (e.g., template setup) is available from the Prime plan upward.
Whatever your business size or digital maturity, SignTime offers a secure, scalable e-signature platform that grows with you.
SignTime for Salesforce is a fully native integration that brings e-signature workflows directly into Salesforce.
From ¥25,000/mo, unlimited users included, and no hidden costs!
