Stop writing contractsby hand.

Describe the agreement in your own words. Pensti writes the draft with signing fields, sends it for signature and keeps the evidence of who signed what and when.

The flow

From description to sealed PDF

01
Describe
Write the agreement the way you would explain it to a colleague: parties, services, price and terms. Pensti writes a draft with numbered sections, or you upload a PDF or pick a template.
02
Review
The draft opens in the editor. Change text, tables and formatting, and move the signing fields, each assigned to a recipient. AI drafts are labelled and never sent without your approval.
03
Sign
Recipients get a personal link by email. They consent, choose or draw their signature and click “Accept and sign”. You control order and reminders.
04
Seal
When everyone has signed, all parties receive the sealed PDF with a certificate of signature. The file's SHA-256 is recorded and timestamped, so any change can be detected.

Evidence

Every event is locked to the one before

Pensti logs the whole flow with server time, IP, device and the document's hash. Events are chained with SHA-256 and the database rejects edits and deletions. Change one event and the chain no longer matches.

SHA-256 frozen at send

The document's fingerprint is locked when it is sent and checked again before every signature.

RFC 3161 timestamps

The audit trail and the final PDF are timestamped by an external timestamp authority.

PAdES-sealed PDF

PDF readers show if the file was changed after sealing. The QR code leads to public verification.
