WHERE SIGI GOES FURTHER

Six things PandaDoc doesn’t do out of the box

Where SIGI creates deeper workflow continuity beyond document creation. 

Connected to your entire operation

SIGI lives inside WorksBuddy alongside CRM, tasks, invoicing, and project management, so signed contracts trigger the next business action automatically.

AI that reads contracts before you sign

Clause intelligence, missing clause detection, and risk scoring protect teams before a document ever reaches the signer.

Stalled deals surface automatically

Signing behaviour analysis predicts completion likelihood and flags at risk agreements before they lapse.

Bulk upload without bottlenecks

Upload up to 20 documents in one flow with individual signer logic and expiry controls per file.

Template version control

Every template edit moves through an approval workflow, ensuring version safe document governance.

One platform, not five tools

Unlike PandaDoc’s document first model, SIGI connects signing to CRM, billing, projects, and automation natively.

REAL CUSTOMER OUTCOMES

How teams perform after moving from PandaDoc

Sales teams, legal teams, and ops teams share why SIGI stood out among every PandaDoc alternative they evaluated.

We were on PandaDoc for two years. What justified the switch was SIGI’s AI risk analysis catching a missing liability clause in a £40k contract before it went out.

We process 80+ offer letters monthly. The whole workflow now runs itself send, remind, collect, and file. No more manual chasing.

The clause intelligence flagged three non standard termination clauses in vendor agreements before execution. External counsel confirmed every issue.

The auto invoice trigger improved our first-month cash flow immediately. Once a client signs, billing starts without handoff delays.

COMMON QUESTIONS

Questions teams ask before switching from PandaDoc

Five key questions teams ask when comparing SIGI against PandaDoc for signing, automation, and AI contract safety.

The moment a contract completes, INZO generates the invoice, TARO creates project tasks, and LIO updates the CRM record automatically. No manual steps, no handoffs. PandaDoc stops at the signature and leaves everything after to your team.
SIGI scans every contract for clause risk, missing provisions, and liability issues before it reaches the signer. Risk analysis runs every 30 minutes on active documents. PandaDoc's equivalent requires a separate CLM product at significant additional cost.
Yes. SIGI supports sequential and parallel signing workflows. You can also run internal approval rounds before the document reaches any external signer. All included on the core plan with no addon required.
SIGI automatically detects signer inactivity after 24 hours and surfaces the at risk agreement before it expires. Reminder sequences escalate automatically. PandaDoc has no native stalled signer detection on any plan.
Every document is protected with SHA-256 hashing, an immutable audit trail capturing IP, device, geolocation and UTC timestamps, and server side geolocation on every action. Legally binding under eSign Act and eIDAS. No security addon required on any plan.

PandaDoc builds your documents. SIGI makes sure they’re safe to sign
