WHERE SIGI GOES FURTHER

Six things Acrobat Sign doesn’t do out of the box

Six capabilities that separate SIGI from every other alternative to Adobe Sign for workflow driven B2B teams.

Connected to your entire operation

A signed contract can instantly trigger CRM updates, invoicing, tasks, and project kickoff inside WorksBuddy for seamless workflows.

AI that reads contracts, not just PDFs

SIGI scans clauses for risk, missing provisions, and severity based issues before sending, ensuring compliant contract review every time.

Stalled deals surface automatically

Predictive signer behaviour analysis flags at-risk agreements before they lapse, helping teams take proactive action and prevent revenue loss effectively.

Bulk upload without bottlenecks

Template version control

Every template edit passes through approval based governance and version history, ensuring accountability, compliance, and full visibility across changes.

A platform that pays for itself

REAL CUSTOMER OUTCOMES

How teams perform after moving from Acrobat Sign

From manual invoicing after every signature to full automation. Real teams share why SIGI stood out among Adobe Sign alternatives.

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.

COMMON QUESTIONS

Questions teams ask before switching from Acrobat Sign

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.
Yes. SIGI works independently of any Adobe or Microsoft ecosystem. Teams sign contracts, trigger invoices, update CRM records, and kick off projects without needing Adobe Document Cloud or Microsoft 365 connected. SIGI replaces the signing layer entirely while adding automation Adobe Sign does not offer.
SIGI detects signer inactivity after 24 hours and surfaces the at-risk agreement before it expires. Reminder sequences escalate automatically. AI signing behaviour analysis predicts which agreements are likely to lapse before they do. Acrobat Sign has no native stalled signer detection on any plan.
INZO generates the invoice, TARO creates project tasks, and LIO updates the CRM record automatically. No manual steps, no handoffs. Acrobat Sign collects the signature and stops there. Everything after requires manual work or a paid Zapier workflow.
Yes. Acrobat Sign starts at enterprise-level pricing with additional charges for advanced workflows and compliance features. SIGI includes AI contract intelligence, automated invoicing, and CRM sync on the core plan with a free tier available to start.

Adobe Sign was built for PDFs. SIGI was built for the entire deal cycle.
