A signed contract can instantly trigger CRM updates, invoicing, tasks, and project kickoff inside WorksBuddy for seamless workflows.
SIGI scans clauses for risk, missing provisions, and severity based issues before sending, ensuring compliant contract review every time.
Predictive signer behaviour analysis flags at-risk agreements before they lapse, helping teams take proactive action and prevent revenue loss effectively.
Upload up to 20 documents at once with unique signer logic and customizable expiry settings defined individually for each file.
Every template edit passes through approval based governance and version history, ensuring accountability, compliance, and full visibility across changes.

We were on Acrobat Sign for three years. The AI risk analysis flagged a missing liability clause in a £40k contract before we sent it. That alone justified the switch.

Acrobat was excellent for compliance, but totally siloed from billing and CRM. SIGI connects the whole chain natively.

Five key questions teams ask when comparing SIGI against Adobe Acrobat Sign for compliance, AI risk protection, and workflow continuity.
Adobe's AI reads and summarizes PDFs for the recipient. SIGI AI protects the sender before the contract goes out. Clause intelligence, missing clause detection, and risk analysis every 30 minutes all ship on the core plan. Adobe's equivalent requires a separate CLM product at significant additional cost.
Move from PDF native signatures into AI contract intelligence, invoicing, CRM sync, and connected project automation.
