What is it?
What is Autessa Document Signing?
Autessa Document Signing is the electronic signature product built into Autessa. It covers the full e-signature lifecycle: preparing a document (upload, signing order, fields, prefilled content, page edits), the signer experience (consent, a field checklist, draw, type or upload a signature, delegate or decline), tracking and closing (milestones, reminders, direct links, mark as executed, void), and proof (PAdES-B-T signatures, a Certificate of Completion and a cryptographically chained audit trail). Reusable templates, folders, sharing, an API, a scripting SDK and embedded signing complete it.
In short
- Free with every Autessa account: unlimited users and unlimited envelopes.
- Send PDFs, Word, Excel, PowerPoint, images and Outlook .msg files for e-signature.
- Sequential or parallel signing, client groups and CC viewers.
- Templates with roles and multi-document sets.
- Sealed PDFs anyone can verify in a standard PDF reader.
- An e-signature API, SDK and embedded signing for your own apps.
What makes it different
The details other e-signature tools skip
Every e-signature tool collects a signature. These are the parts of Autessa Document Signing that make the difference on real contracts with real people.
Upload any document
Autessa Document Signing accepts PDFs, Word, Excel, PowerPoint, OpenDocument, RTF, text, HTML, Pages, Outlook .msg and image files and converts each to a PDF on upload.
Read more →Client groups (any one signs)
A client group puts several people in one signer slot so that any one of them can sign for it, and an envelope can also be set to complete on the first signature.
Read more →CC viewers
Viewers are CC recipients who never sign: Autessa emails them a read-only copy on send, a clearly marked progress copy after each signature, and the sealed document at the end.
Read more →Prefilled content
Prefilled content (static text, multi-line text, static dates and images) is filled by the sender and flattened into the PDF at send, so every signature covers it and no signer can change it.
Read more →Page editing and redlines
Before sending, you can delete pages, append a PDF addendum, reorder pages and draw red strike lines through clauses, and the document is frozen once it is sent.
Read more →Delegate signer
Delegate signer lets a recipient add an alternate signer to their own slot, so either person can sign, with both named on the audit trail.
Read more →Direct signing links
Direct links give you a per-recipient signing link and one envelope-level link, so you can deliver signing outside email or sign in person on a tablet.
Read more →Signed copies for everyone
At completion every signer and viewer receives a link to a hosted download page that mints a fresh short-lived URL each time and offers a request-a-new-link button.
Read more →Mark as executed
Mark as executed seals a sent envelope with the signatures collected so far, marks the rest not required, closes their links and sends the final copy to those who signed.
Read more →Tamper-evident audit trail
Every envelope carries a cryptographically chained audit trail in which each event hashes into the next, so removing or altering an entry breaks the chain and shows Chain compromised.
Read more →PAdES digital signatures
Each signature is embedded in the PDF as a PAdES-B-T digital signature with an RFC 3161 trusted timestamp, keyed to an ephemeral per-signer certificate.
Read more →Multi-document templates
A template can hold a document set whose fields anchor to each document, so adding, replacing, reordering or renaming one file never moves fields on the others.
Read more →Scripts and automations
The autessa.eSignature SDK lets scripts, table triggers, scheduled jobs and agent tools create, send, remind and download envelopes inside Autessa.
Read more →Embedded signing
Custom Apps can render the hosted signer inline with the PdfSigner component, so users sign without leaving your app or opening an email.

Prepare and send a document for signature
The builder walks four steps, saves as you go, and refuses to send a contract with empty required clauses.
Step 0 · Upload
Start from the file you already have
- PDF, Office, OpenDocument, RTF, text, HTML, Pages, .msg
- PNG, JPG, GIF, BMP, TIFF and HEIC images
- Title filled in from the file name
Step 1 · Recipients
Decide who signs, and in what order
- Contact autocomplete from people you have sent to
- Client groups: any one of several people signs a slot
- Viewers CC’d on every version
Step 2 · Fields
Drag fields onto the page, and prefill the terms
- Color-coded to each signer slot
- Undo, redo, copy, paste and duplicate shortcuts
- Prefilled content flattened into the PDF on send
Step 3 · Review
One last look, then send
Track
Know exactly where every envelope stands
- Send reminder and Resend link
- Have an agent call or email a signer who has not signed
- Direct links when email fails
- Mark as executed or Void
Templates
Repeat documents become a two-minute job
Organize and share
Private by default, shareable on purpose
Product tour · For your signers
What your signers see
No account, no app, no password. A link, a consent screen, a checklist and a button, on a computer, tablet or phone.
Consent and identity
Signers agree to sign electronically before they see fields, and confirm who they are before submitting.
A checklist to every field
Click an item to jump to it. Nobody hunts for the one initials box on page 31.
Draw, type or upload
Three ways to adopt a signature, previewed before it is applied.
Up close
Built for how contracts actually get signed
Any one of them signs
Put several client contacts in one slot and the first available signs for all of them.
Viewers get every version
On send, after each signature (marked not yet fully executed) and sealed at the end.
Direct links beat spam filters
Per-recipient and envelope-level links for chat, text or in-person signing.
How it works
How does sending a document for e-signature work in Autessa?
Four steps in the builder, then Autessa takes it from there.
- 0
Upload
PDF, Word, Excel, images, .msg and more

Recipients
Signing order, slots, client groups, viewers
- 2
Fields
Drag fields, prefill content, edit pages
- 3
Review
Check every slot, write the message, send
Prefill is flattened
Your static content becomes part of the PDF. These bytes are what every signature covers.
Links are minted
Each recipient gets a unique, single-use link. Autessa stores only its hash.
Invitations go out
To every signer, or only slot 1 under One at a time. Viewers get a read-only copy.
Signatures accumulate
Each signer’s submission embeds a PAdES signature that covers everything before it.
The PDF is sealed
The last signature appends a Certificate of Completion and emails everyone a download link.
Audit trail and sealed PDFs
A signed PDF that proves itself
Each signature is embedded as a PAdES-B-T digital signature with an RFC 3161 trusted timestamp, keyed to an ephemeral per-signer certificate. Signatures accumulate, each covering everything before it, and a Certificate of Completion is appended at the end. Any change after signing is detectable in any standard PDF reader, not only in Autessa.
- Hash-chained audit trail with a Chain verified badge
- Actor, IP address, browser and time on every event
- SHA-256 hashes of the original, prefilled and sealed PDF
- Consent and identity attestation from every signer
Certificate of Completion
The proof travels with the contract
When the last required signer finishes, the certificate is appended, the PDF is sealed, and every signer and viewer gets a download link that keeps working.
Certificate of Completion
Master Services Agreement · Completed Jul 15, 2026This certificate is cryptographically bound to the document via PAdES.
Multi-document templates
Replace one file, keep every field
Fields anchor to each document in a template’s set, so when Legal sends back a revised terms sheet you swap just that file.

Use cases
Who uses e-signatures in Autessa?
Sales and account teams
Order forms, MSAs and renewals that need an internal approver first and the customer’s countersignature last.
People and HR
Offer letters and onboarding packs sent from templates, with HR CC’d as a viewer on every one.
Legal and operations
Multi-document agreements, redlines before sending, and a tamper-evident record for every contract.
Agencies and professional services
Engagement letters and scopes where any one of several client contacts may sign.
API, SDK and embedded signing
Does Autessa have an e-signature API?
Yes. The Poweruser API creates, sends, reminds, voids and downloads envelopes and works with templates and folders. The autessa.eSignature SDK runs the same operations inside scripts, table triggers, scheduled jobs and agent tools. Apps you build on Autessa embed signing with the PdfSigner component, and the Autessa CLI lists, inspects, downloads and files envelopes. All of them drive the same service, with the same audit trail.
Security
How is a signing link protected?
Each signing link is a single-use, high-entropy token that exists only in the recipient’s email; Autessa stores a hash of it and never the token itself. Envelopes are private to their owner until shared, every share is on the audit trail, sent documents are frozen, and completed contracts can never be deleted.

E-signature questions, answered
What is Autessa Document Signing?
Autessa Document Signing is e-signature software built into Autessa. You upload a document, choose who signs and in what order, drag signature fields onto the pages and send it; signers sign in the browser from an emailed link, and the finished PDF is sealed with PAdES digital signatures, a Certificate of Completion and a tamper-evident audit trail.
Is Autessa Document Signing free?
Yes. Autessa Document Signing is free with every Autessa account, for unlimited users and unlimited envelopes: everyone on your team can send, with no per-seat fees and no envelope limits. You pay only for AI tasks.
Does it work out of the box?
Yes. Upload a document, add signers and fields, and send it the same day, with sealing, the audit trail and the Certificate of Completion built in. From there you tailor it to how your company works in Autessa: templates and roles, signing order, folders and automations that send and file envelopes for you.
Do signers need an Autessa account?
No. Signers get an emailed link and sign in the browser with no account, app or password. The link itself is the credential: a single-use, high-entropy token that Autessa stores only as a hash.
Can I send a Word document for signature?
Yes. Autessa accepts PDF, Word, Excel, PowerPoint, OpenDocument, RTF, plain text, HTML, Pages, Outlook .msg and image files (PNG, JPG, GIF, BMP, TIFF, HEIC) up to 25 MB, and converts anything that is not already a PDF on upload. What signers see and what gets sealed is the converted PDF.
Can people sign in a specific order?
Yes. Choose One at a time and only signer slot 1 is invited on send; when they finish, slot 2 is invited automatically, and so on. Choose Everyone at once and all signers are invited together.
How do I prove a signed document was not changed?
Every signature is embedded as a PAdES-B-T digital signature with an RFC 3161 trusted timestamp, so any change after signing is detectable in any standard PDF reader. The envelope also keeps SHA-256 hashes of the original, prefilled and sealed PDFs and a cryptographically chained audit trail with a Chain verified badge.
Are Autessa electronic signatures legally binding?
Autessa’s signing flow is built around what electronic signature laws such as the US ESIGN Act and UETA look for: each signer consents to electronic records and signatures, confirms who they are before submitting, and every action is recorded on the audit trail and summarized in a Certificate of Completion. Whether a particular document can be signed electronically depends on its type and jurisdiction, so check with your counsel for regulated documents.
Can I CC someone who does not need to sign?
Yes. Add them as a Viewer. Viewers get a read-only copy when you send, a progress copy marked not yet fully executed after each signature, and the sealed document when everyone has signed. They never hold up completion.
Does Autessa have e-signature templates?
Yes. A template holds a document set, a field layout and named roles such as Client and Provider, plus the signing order, completion policy and viewer roles. To send, click Use template and assign a person to each role.
Does Autessa send automatic reminders?
Yes. In the web app, Send reminder emails everyone outstanding and Resend link emails one person. For scheduled chasing, a scheduled script can call the reminder action through the AutessaScript SDK or the API. You can also have an agent call or email a signer who has not signed.
Is there an e-signature API?
Yes. The Autessa Poweruser API and the AutessaScript SDK (autessa.eSignature) create, send, remind, void and download envelopes and work with templates and folders. Apps you build on Autessa can embed signing with the PdfSigner component, and the Autessa CLI can list, inspect and file envelopes.
What happens if an invitation goes to spam?
Open the envelope and use Direct link. You get a link per recipient that opens straight into signing, and one envelope-level link where whoever opens it enters their email to reach their own slot. Paste either into a chat, a text or a calendar invite.
Is Autessa a good DocuSign alternative?
For teams that want signing order, client groups, CC viewers, templates, direct links and PAdES-sealed PDFs in the same place as their CRM, HR, files and apps, Autessa Document Signing is a strong alternative. It is built into Autessa, so contracts sit next to the rest of your work.
