Unlimited Signature Model

Zignt's foundational feature is its predictable pricing model that eliminates per-signature fees. This allows businesses to send contracts for signature an unlimited number of times without incurring additional costs, enabling scalable growth and significant cost savings. This model transforms contract execution from a variable expense into a fixed, manageable operational cost, providing clear financial forecasting and eliminating budget surprises associated with high-volume signing periods.

Intelligent Template & Batch Management

Create reusable contract templates by simply dragging and dropping fields onto a PDF. Configure a template once and use it unlimited times, saving hours on every subsequent agreement. This feature is paired with intelligent batch sending, allowing teams to prepare and dispatch multiple contracts simultaneously. This drastically reduces administrative overhead and ensures consistency across all documents, standardizing processes and accelerating deal velocity.

AI-Powered Renewal Tracking

Zignt's AI automatically scans uploaded contracts to identify critical dates, such as renewal and expiration milestones. It then provides a centralized renewal dashboard for at-a-glance visibility and sends smart, customizable reminders before key deadlines. This proactive feature prevents revenue leakage from missed renewals and avoids auto-renewal pitfalls, ensuring businesses maintain optimal control over their contractual commitments and vendor relationships.

Enterprise-Grade Security & Compliance

Every action within Zignt is protected by bank-level 256-bit SSL/TLS encryption for data both in transit and at rest. The platform is built to be legally binding and compliant with international standards including the U.S. E-SIGN Act, UETA, and the EU's eIDAS regulation. It also adheres to GDPR for data privacy. Each signed document includes an automatic, court-admissible audit trail with timestamps, IP addresses, and signer details, ensuring full legal defensibility.
