E-signature for engagement letters, representation letters and reports

Waiting for a signed engagement letter or representation letter can hold up an audit for days. Stowbill sends the document for signature from inside the engagement, records strong evidence of who signed what and when, and ticks the matching checklist item when it's done.

How signing works

  • Upload the letter or report as a working paper, then request a signature from the client's signatory or a partner.
  • The signer gets an email link, downloads and reads the exact document, and asks for a one-time code sent to their email.
  • They enter the code, type their full name and tick a consent statement.
  • Stowbill checks the document hasn't changed since the request, records the signature, and emails a certificate to the signer and the engagement leader.

Questions

Does the signer need an account?

No. They use the link in their email and a one-time code.

What happens if the document changes after the request?

Signing is blocked, and you send a new request for the updated version.

Can partners sign the auditor's report this way?

They can record approval this way. Check whether your regulator's filing process requires a different form of signature.
