Online Esign Tool

The tool enables secure online signature collection on PDFs and common document formats. It handles document input via upload or API, signer data, and signing fields (signature, initials, date). It supports templates, signer roles, and configurable signing workflows with sequential or parallel routing and automatic reminders. The result is a final, legally recognizable PDF and a tamper-evident audit trail.
Conceptually, a signing session is created with verifiable invitations. Signers authenticate using chosen methods (email link, OTP, or in-app verification), place their signatures or initials, and submit. Each action is timestamped, cryptographically tied to the document, and recorded in an immutable audit log for non-repudiation. All data is stored with strong encryption and retention controls.
Security and compliance are core: documents are encrypted at rest and in transit, access is controlled by roles, and activity is auditable via detailed logs. The tool offers API access and webhooks to integrate with CRMs, contract stores, and workflow systems. It supports templates, bulk sending, reminders, and expiry handling to reduce bottlenecks.
Industry and localization considerations include compliance with US ESIGN Act and EU eIDAS, as well as local data privacy rules. Signer locales, date formats, and legal language can be adapted. Assumptions include that signers have consented to electronic signing and that documents do not require notary services. Exclusions cover offline notarization and notary verification outside the defined API surface.
