Web app
Everything in the browser. Nothing to install.
The web app at app.centerleap.com is the operator’s desk: fast, keyboard-driven, and built for long days.
Drag-and-drop field placement
Drop signature, initials, date, and text fields onto any PDF.
Reusable templates
Build once; reuse with merge fields for recipient name, role, and routing order.
Routing order
Sequential, parallel, or hybrid signing — the envelope advances when each step is complete.
Saved signatures
Recipients save a typed or drawn signature once and reuse across envelopes.
Audit trail
IP, user agent, timestamp, and signer email captured per signature event. Exportable as a certificate.
Two-tier identity verification
Email magic-link by default; SMS or knowledge-based authentication for high-stakes envelopes.
