PTR e-Sign sends your PDF to anyone for signature — they sign from any device via a secure email link, no account needed. You get back a stamped, cryptographically sealed PDF with a complete audit-trail certificate, built for 21 CFR Part 11 and IT Act 2000 compliance.
Any PDF up to 25 MB — contracts, offer letters, quality agreements, approvals, NDAs.
Drag signature, initials, date, text, name, email, dropdown and checkbox fields exactly where they belong on the document.
Up to 10 signers, signing sequentially — recipient 2 is invited automatically only after recipient 1 has signed.
Each signer gets a secure one-time email link — draw, type or upload their signature from any phone or computer. No account, no app.
Everyone receives the final PDF: fields stamped, completion certificate appended, and the whole file cryptographically sealed.
Built by the team behind Training Master Pro and InstruManage — the same 21 CFR Part 11 discipline, applied to signatures.
Place signature, initials, date, text, name, email, dropdown and checkbox fields visually on the rendered PDF — per recipient, required or optional.
Signers authenticate with a cryptographic 64-character one-time token in their email — no passwords, no registration, rate-limited against abuse.
Strict signing order enforced server-side — it is never "your turn" until the previous signer finishes. Reminders and voiding at any point.
Draw with mouse or finger, type a name rendered as a signature, or upload a signature image — the signer chooses.
Every finished document gets an appended certificate: signer identities, IPs, timestamps, SHA-256 of the source, and the complete append-only event timeline.
The final PDF is signed with an RSA-2048 PKCS#7 signature embedded in the file — any byte-level tampering afterwards visibly breaks the seal in Adobe Reader.
Database triggers make the audit log physically impossible to edit or delete — aligned to 21 CFR Part 11 §11.10(e).
Designed around IT Act 2000 §3 (India), ESIGN Act / UETA (US) and 21 CFR Part 11 signature manifestation and record-linking requirements.
