Katalyz Signature

Katalyz Signature embeds legally binding electronic signatures directly in your rooms. No DocuSign roundtrip, no PDF attachments — sign where the deal happens.


⚠️ Paid module — €20 per user per month, on top of the Core plan. Per seat, never discounted. Envelopes do not use credits.


What you can do


  • Embed a signature widget in any room — right next to the pricing, the proposal, the CTAs
  • Send envelopes to multiple signers — sequential or parallel routing
  • Collect signatures legally bound — compliant with major e-signature frameworks
  • Track status inline — see who viewed, who signed, who's stuck
  • Auto-deliver the sealed PDF — to all signers, approvers, and CCs once completed

Pricing


  • Katalyz Signature is billed per user per month (€20), for every user on your plan.
  • There is no per-envelope cost and no credit deduction — send as many envelopes as you need.
  • To add the module, go to Settings → Workspace → Plan & Billing → Modules and click Request to add; it's added to your contract by our team.

Katalyz signatures are electronic signatures suitable for most commercial contracts. Documents (PDF or Word) are cryptographically sealed — any modification invalidates the seal and is detectable by any PDF reader.


For specific framework compliance details (SOC 2 / GDPR / HIPAA / regional regulations) and deeper legal context, see Legal validity of Katalyz signatures.


Authentication methods


Each recipient authenticates before signing. Four methods are supported:


  • Email Link (default) — one-click from the invitation email
  • Email Code — 9-digit code emailed to the recipient
  • Custom — the room's magic-link session authenticates them
  • Multiple — combine methods for higher-assurance scenarios


Field types


A signature envelope can contain:

  • Signature fields
  • Initials fields (can span all pages)
  • Date fields (auto-filled)
  • Text input fields (editable)
  • Annotation (creator-only, static text)


Audit trail


Every envelope produces:

  • A tamper-evident, cryptographically sealed final PDF
  • A timestamped record of every event (viewed, signed, declined, cancelled)
  • Retention for the lifetime of your Katalyz account


Common use cases


  • Sales contracts — MSA, order forms, pricing agreements
  • NDAs — before sharing sensitive information
  • Change orders — signed amendments to existing deals
  • Internal approvals — routing for sign-off before sending externally
  • Onboarding agreements — customer onboarding documents
