See an envelope up close
Our team builds a flow with you: documents, signers, validations and the certificate of completion at the end. Get answers about features, plans and implementation directly on WhatsApp.
An envelope gathers multiple documents and multiple signers into a single signing flow — you send once and the whole process moves together.
At the end, a single certificate of completion consolidates who signed, when, from where and with which validations.
Signater's unit of work: documents, signers and evidence gathered into a single flow.
Upload PDF, Word, spreadsheet or image files: everything is converted to PDF and hashed on upload. Up to 20 documents per envelope on Starter, 50 on Business and no limit on Enterprise.
Each one with their own fields and validations, signing in sequential order or in parallel. Limits match the documents: 20, 50 or no limit, depending on the plan.
Once the envelope completes, a single document consolidates the history of the process from start to finish, with a SHA-256 hash of each file for integrity checks.
Schedule publication (and unschedule if you change your mind), pause, cancel or let it expire at the deadline — every transition is recorded in the envelope history.
Assembly: documents, signers and fields
Publishes automatically on the chosen date
Signers notified and signing
Certificate of completion generated and sealed
Detours
Paused
Suspends the signing flow temporarily. Resume whenever you want.
Canceled
Ends the envelope before completion: while drafted, scheduled, published or paused.
Expired
Set a deadline? An envelope that is not completed by then expires on its own.
Templates
Instead of uploading a PDF, pick a template and fill in the data: the document is generated on the spot, ready for signing.
Combine multiple templates and build hybrid flows — generated documents and uploads in the same envelope, including via API.
Signing order
In a sequential flow, each signer is released when the previous one finishes — useful when the director only signs after the client.
In parallel, everyone receives the invitation at the same time and signs in whatever order they prefer. The envelope completes when the last signature arrives.
Identity validation
Decide, per signer, how identity gets confirmed: codes by email, SMS or WhatsApp, PIX, selfie with liveness, password, A1 certificate and more — nine factors you can combine.
The partner signs with PIX and a selfie; the witness, with the email code. Every validation becomes evidence in the certificate.
Send the invitation by email, SMS or WhatsApp, or collect the signature in person: each signer signs through the channel that makes sense.
Each signer receives an individual link by email, SMS or WhatsApp, revocable at any moment if you need to block access.
Generate the link on your own device to collect the signature on the spot: in self-signing mode or with a third party signing right there.
The signer opens the link and signs straight in the browser, on whatever device is at hand. On mobile, the responsive interface means no app to install.
Place marks and fields on any page, with free position, size and rotation, and assign each one to a specific signer.
Signature where each signer signs the document
Initials handwritten, uploaded as an image or typed
In the attachment field, the signer uploads files during the signing itself.
Instant format validation for email, phone and number fields: the signer can only submit data in the right format.
Follow-up
Automatic reminders nudge whoever has not signed yet, without you chasing every pending signature.
To speed up a specific case, resend the invitation manually. Protection against repeated triggers keeps the signer from being bombarded with messages.
And every move reaches you in real time: views, signatures, refusals and completion show up as notifications on the platform.
Reports
The signer actions report shows what happened in each envelope: who viewed, who signed, on which date — and from which location.
Certificate of completion
Every envelope automatically generates a certificate of completion: the consolidated, sealed record of the entire process, ready for audit.
Global search
Type the contract title, the signer's name or the file inside it: global search sweeps envelopes, documents, contacts and signers in a fraction of a second.
Results come grouped by type and open right where you need them — no digging through lists.
It is Signater's unit of work: a package with one or more documents and one or more signers, all moving through the same signing flow together. At the end, the envelope generates a single certificate of completion with the full history of the process.
It depends on the plan: up to 20 documents and 20 signers on Starter, up to 50 and 50 on Business, and no limit on Enterprise. The maximum size per document also varies: 25 MB, 50 MB and 100 MB, respectively.
A signer can decline instead of signing, and the outcome is recorded with date, time, IP address and device. You are notified in real time, and the refusal appears in the envelope history and in your reports.
Yes: you set the date, the envelope publishes itself and the signers are notified. Before publication, you can unschedule it. You can also set a deadline, after which an envelope that has not completed expires automatically.
Yes. Instead of uploading, pick a template and fill in the data: the document is generated on the spot. You can combine multiple templates and uploads in the same envelope, including via API.
By choosing factors per signer: codes by email, SMS or WhatsApp, PIX, selfie with liveness, password, A1 certificate and more. Every validation becomes evidence in the certificate of completion.
Every signed page carries a QR code that leads to the public verification page. Anyone with the link can download the original document, the signed one and the certificate of completion, and check the printed SHA-256 hash to confirm integrity.
