Engagement letters out in seconds
CyberSygn detects the signature and date fields on a bookkeeping engagement letter or service agreement in about three seconds, so a new client is signed and you can start reconciling without a paperwork delay.
For bookkeepers.
The e-signature tool that gets your engagement letter signed before month one
You are onboarding clients onto recurring service and need an engagement letter and an authorization signed before you can touch their books, and a signing portal that demands an account slows every new client down. 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 bookkeepers actually work.
Clients sign without another login
A small business owner opens the link and signs between other tasks, with no account and no app. That is how a busy owner actually gets your engagement letter signed rather than leaving it open in a tab.
A clear record of the engagement
Each signed document carries a SHA-256 audit certificate showing who agreed and when, so your engagement letters and authorizations sit on file with a tamper-evident audit trail.
Every agreement.

Common questions.
Questions bookkeepers ask.
Can I onboard a new client quickly?
Yes. The AI places the fields in about three seconds and the client signs from a link with no account, so the engagement letter is signed before you begin the work.
Do clients need to create an account to sign?
No. They sign in their browser with no login and no app, which is the easiest path for a business owner juggling their own work.
Is there a record of the signed engagement?
Every completed document includes a tamper-evident SHA-256 audit certificate recording who signed and when, which you can retain in the client file.
