Where SIGI creates stronger workflow continuity beyond PDF native signing.
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.
Unlike Acrobat Sign’s enterprise heavy pricing, SIGI combines signing, AI protection, and post sign workflows on a growing team budget.
