Zignt

Reusable Contract Templates

Stop recreating the same documents from scratch. Zignt allows you to build professional contract templates by easily adding date fields, text boxes, and signature blocks to your PDF. Configure a template once and reuse it unlimited times for future agreements, saving hours of repetitive work on every single contract you send. This ensures consistency, reduces errors, and dramatically speeds up your preparation process.

Seamless Sharing & Multiple Signing Options

Eliminate the back-and-forth of email attachments. Send contracts directly via email with automated reminders, or generate a secure Zignt Link—similar to a payment link—for easy access. You can even enable optional ID verification for signers. Recipients can sign with a typed or drawn handwritten signature, providing flexibility and a smooth experience for all parties involved, which accelerates closure.

AI-Powered Renewal Tracking

Never miss a critical contract date again. Zignt's AI automatically scans your executed contracts to identify and extract key dates like renewals, end dates, and milestones. It then provides smart, customizable reminders and a centralized renewal dashboard, giving you a clear overview of upcoming deadlines. This proactive approach prevents revenue loss and ensures you stay ahead of every obligation.

Legally Binding & Bank-Grade Security

Execute agreements with absolute confidence. Every signature through Zignt is protected by 256-bit SSL/TLS encryption and is compliant with major international standards like the E-SIGN Act, UETA, and eIDAS. An automatic, court-admissible audit trail records IP addresses, email details, timestamps, and signer actions, providing full traceability and legal enforceability for complete peace of mind.

Zignt

Accelerating Sales Cycles

Sales teams can close deals faster by instantly sending proposals and sales agreements from pre-approved templates. The ability to share via a link or email and receive legally binding signatures in minutes eliminates the traditional week-long waiting period, accelerating revenue generation and improving the client onboarding experience without any per-signature costs.

Streamlining HR & Onboarding

Human Resources departments can efficiently manage the influx of offer letters, NDAs, and policy acknowledgments. By using templates for standard documents and sending them in batches, HR professionals can onboard multiple new hires simultaneously, track completion status easily, and maintain a secure, organized digital record for every employee.

Managing Vendor & Supplier Agreements

Operations and procurement teams can gain control over vendor contracts. Zignt simplifies the sending, signing, and tracking of supplier agreements, service contracts, and SOWs. The AI renewal tracking feature is crucial here, sending alerts before contracts auto-renew, allowing teams to renegotiate terms or switch vendors proactively to control costs.

Legal teams can enforce consistency and reduce risk. By creating a centralized library of vetted contract templates, legal counsel ensures all departments use the correct, up-to-date language. The automatic audit trail and compliance data (IPs, timestamps) provide a defensible record, simplifying e-discovery and protecting the company in any dispute.
