For professionals

Protect what you sign.

For law firms, accountants and consultants. Stamp the letters and certified copies you issue, and anyone relying on them can confirm they’re genuine in seconds, without calling your office.

Your name is your practice.

Your letterhead gets borrowed

A scanned letter is all someone needs to produce a convincing fake in your name.

Certified copies get edited

A date or figure changes after the document leaves your office, and nobody can tell.

Your phone keeps ringing

Banks and counterparties call to confirm what you sent, and your team stops to answer.

What you can stamp.

Any document that leaves your office with your name on it.

  • Demand and advocate letters
  • Professional undertakings
  • Certified true copies
  • Sale and lease agreements
  • Audit and review opinions
  • Tax compliance letters
  • Engagement and confirmation letters
  • Consultancy reports and certificates

Fits how your practice already works.

  • Stamp in minutes

    Upload the final PDF, choose the client, place the stamp and sign. Your usual document stays the same.

  • Confidential by default

    A verifier can see that a document is genuine without seeing its contents, unless you allow it.

  • Room for the whole firm

    Add partners and staff, and issue in bulk on Growth when matters pile up.

  • Nothing to install for others

    Clients share the stamped file as usual. Anyone checking just scans the QR code or types the code.

Priced for practices, not corporations.

Questions professionals ask.

Does this replace my signature or seal?

No. You keep signing and sealing as you do now. Authstamp adds a way for anyone to confirm the document really came from you and hasn’t changed.

Can a verifier read my client’s confidential document?

Only if you allow it. You choose for each document whether a verifier sees just the result, part of it, or the full file, and whether they must know the client’s details first.

What if the client edits the PDF after I send it?

The check compares against the record Authstamp holds, not the file. An edited copy won’t match what you issued.

Which professions is this for?

Advocates, accountants, auditors, tax advisers, valuers, surveyors, engineers and consultants. Anyone whose signed documents others rely on.
