Six reasons SIGI is the cheapest DocuSign alternative that does not trade features for affordability
Clause intelligence, missing clause detection, and rolling risk analysis run automatically on every active agreement, helping teams catch liabilities before documents are sent.
The moment a contract is completed, SIGI triggers INZO to generate and send the invoice automatically, removing billing lag and improving cash flow.
SIGI tracks viewing behaviour, partial progress, and signer inactivity to surface at risk agreements before they expire or go cold.
Upload up to 20 agreements in a single flow, each with its own workflow rules, signer logic, and expiry settings, ideal for sales and HR teams processing volume.
Every template update moves through an approval workflow with full edit history, ensuring teams always know which version was sent and who approved it.
Because SIGI lives inside WorksBuddy, a signed contract can instantly trigger CRM updates, project kickoff, task creation, and invoicing without manual handoff.
