SigTANA

E-Signatures & Documents

E-signatures, built in. Court-defensible by default.

E-signatures shouldn't be a separate subscription with per-envelope fees and a separate login. SigTANA is built into every Doortana workflow — and unlimited at every tier.

  • Doortana detects signature, initial, and date fields on any PDF — no manual placement
  • Multi-signer orchestration with identity verification
  • Unlimited e-signatures included at every tier — no per-envelope fees

The Doortana Difference

Doortana scans any PDF you upload and places signature, initial, and date fields automatically — even on the back-of-envelope addendum a counterparty just sent over. You review and adjust, then send. No grid setup. No manual placement.

How it connects

Signed documents update the right milestone in FlowTANA, advance the right phase in SellTANA, and move the client forward in ClienTANA — automatically.

Unlimited e-signatures. Included.

No per-envelope fees. No separate subscription. Just sign.

Public Launch Coming Late Summer 2026
