What our customers say

Camila Ferreira

Legal Manager

What helped most was the visibility. We used to have to ask several people which stage each contract was in. Now we can track everything from the platform.

Bruno Almeida

Head of Technology

The integration was smoother than we expected. Within a few days we were already automating steps that used to depend on manual follow-up.

Patrícia Lima

HR Coordinator

Signing from a phone made a real difference for candidates. Documents that used to take days are now resolved in a few hours.

Rafael Souza

Head of Operations

We had documents scattered everywhere. With Signater it became much easier to track who has signed, who's still pending, and what needs attention.

Frequently Asked Questions

We've compiled the most common questions to help you better understand how our platform works.

Are signatures legally valid?

Yes! Signatures made through Signater are fully legally valid worldwide, in compliance with the ESIGN Act (USA), eIDAS (EU Regulation 910/2014), and equivalent regulations across 20+ countries.

We use advanced encryption and digital certificates to ensure maximum security and authenticity, guaranteeing your documents are legally recognized across multiple jurisdictions.

What is the difference between an electronic signature and a digital signature?

An electronic signature is a broad term encompassing any digital signing method. A digital signature is a specific category that uses advanced cryptography and digital certificates to ensure maximum security, authenticity, and non-repudiation.

At Signater, we offer both types, allowing you to choose the ideal security level for each document type.

Do the plans require a long-term commitment?

No! Our plans are 100% commitment-free. You have full freedom to cancel at any time without additional costs, penalties, or red tape.

After cancellation, no automatic renewals will be processed and you retain access to your plan features until the end of the current billing cycle.

How do you verify signer identity?

Signater offers multiple identity verification methods: OTP authentication via email and SMS, bank account verification, facial recognition with liveness detection, and geolocation.

You can combine multiple methods per document based on criticality level. Every action is recorded in immutable audit trails with evidentiary value.

How much does it cost to send a document for signature?

We offer three flexible and scalable plans:

  • Signater Starter: $39/month — 20 envelopes included, unlimited users, and all essential features.
  • Signater Business: $199/month — 100 envelopes included, everything in Starter plus API, Webhooks, AI, and Sandbox.
  • Signater Enterprise: $499/month — 200 envelopes included, everything in Business plus White Label and managed accounts.

Can I send multiple files in a single document?

Yes! With Signater you can attach as many files as you want to a single document at no additional cost. This greatly simplifies the process when you need to send contracts with attachments, multiple pages, or supplementary documents.

All files are signed together, saving time, plan envelopes, and making organization easier.

What happens if I cancel my plan?

When you cancel, you retain full access to all features of your current plan until the end of the billing cycle — without losing any functionality.

After that period, your account is automatically converted to the free plan, permanently preserving all documents already created and signed. You never lose access to your history.
