For accountants.

The e-signature tool that clears your tax-season signature backlog

During tax season you are chasing dozens of engagement letters and e-file authorizations at once, and every client who cannot figure out a signing portal becomes a phone call you do not have time for. CyberSygn finds every signature line, date, and initial automatically in about three seconds, your client signs from a link with no account, and each completed document carries a tamper-evident audit trail.

Why CyberSygn.

Built for how accountants actually work.

Send an engagement letter in seconds, not minutes

CyberSygn's AI places the signature and date fields on an engagement letter or e-file authorization in about three seconds, so you can push out a whole batch of clients in the time it used to take to prep one.

Clients sign without a portal login

Your client opens the link and signs, no account and no app. That eliminates the single most common tax-season support call, the one where a client cannot get into the signing system.

A documented record for every authorization

Each signed document carries a SHA-256 audit certificate showing who signed and when, giving you a tamper-evident audit trail for engagement letters, e-file authorizations, and disclosure consents.

Every agreement.

The contracts accountants send, signed in seconds.

  • Engagement Letter
  • E-File Authorization Form
  • Tax Preparation Agreement
  • Disclosure Consent

Drop any of them in as a PDF. CyberSygn detects the fields, you send, they sign. No dragging boxes, no accounts, no per-document setup tax.

Common questions.

Questions accountants ask.

Can I send the same engagement letter to many clients quickly?

Yes. Because the AI detects the signature fields automatically in about three seconds, prepping and sending each document is fast, which is what you need when the whole client list needs to sign at once.

Do clients need an account to sign an e-file authorization?

No. They sign from the link in their browser with no login and no app, which cuts down on the support calls that pile up during filing season.

Is there a record I can keep for compliance?

Every completed document includes a tamper-evident SHA-256 audit certificate recording the signer and timestamp, which you can download and retain in the client file.

Send your first contract in about 30 seconds.
