Go to create account with your email and a password. You'll receive a verification message; once you confirm it, your account is activated and you can start sending signature envelopes.

You need the PDF, the email of each recipient, and the fields you want them to fill out or sign. From the dashboard click New envelope, upload the PDF, add recipients and drag fields onto the document (signature, initials, date, text, checkboxes, etc.). When ready, send the envelope.

During the current phase the service is offered at no cost on the available plans. If paid plans are introduced in the future, their price and conditions will be shown clearly before you commit.

We accept standard PDFs up to 50 MB. If the document is password-protected you must unlock it before uploading. Documents previously digitally signed may require additional flows.

Inside the envelope editor add as many recipients as you need. You can choose between sequential order (each signs after the previous one finishes) or parallel (everyone gets the invitation at once). You assign each recipient their own fields.

Yes. When adding a recipient you can mark them as cc and they'll receive the completed envelope without having to sign.

Pending envelopes receive automatic daily reminders while they remain open and not expired. You can also send a manual reminder from the envelope view.

Yes, as long as it's not yet completed. From the envelope view click Void and provide an optional reason. Pending signers are notified and the links stop working.

If you set an expiration date and it's reached with pending signatures, the envelope moves to expired and the links stop working. You can duplicate it and resend if needed.

When the envelope is completed, all signers receive the signed PDF by email. As the sender, you can download it any time from the envelope view, along with the audit certificate.

From the Templates section create a new one, upload the base PDF, define roles (instead of specific recipients) and place the fields. When you use it, you'll only need to fill in the signers' details.

Yes. Changes to a template only affect future envelopes generated from it. Envelopes already sent keep exactly the configuration they were sent with.

Click the button in the email. A secure page with the document will open. After reading the electronic signature notice and accepting the terms, you'll receive an OTP code by email to confirm your identity. Then you can fill in the fields and sign.

Check your spam folder. If after a few minutes it still hasn't arrived, click Resend code. If the issue persists, contact the envelope sender or write to support@signbona.com.

Yes. On the signing page you'll find the Decline option. You can provide a reason. The sender is notified and the envelope moves to declined.

No. To sign, the email link and OTP code are enough. You only need an account if you want to send envelopes yourself.

Each document is signed in PAdES format with a certificate issued by our internal certification authority and stamped with an RFC 3161 timestamp. The process is recorded in an event chain protected with HMAC-SHA256. It meets the requirements of a legally binding electronic signature under the ESIGN Act (15 U.S.C. §7001 et seq.) and the UETA.

Open the PDF in a compatible viewer (Adobe Acrobat Reader, for example). You'll see the signature, its timestamp and the signer certificate. For Acrobat to mark it as trusted, you need to add our root certificate as a trusted authority; you can download it at /api/ca/sign-ca.cer.

It's a PDF generated when the envelope is completed and summarizes the entire cycle: recipients, dates, signer IP and user-agent, document hashes, timestamps and the chained hashes of each event. You can download it from the envelope view and keep it as evidence.

Any subsequent modification invalidates the signature: the viewer warns that the document has been altered after signing. In addition, the audit chain detects tampering with the process records themselves.

For most private contracts, yes. Certain acts require qualified electronic signatures or additional formalities (for example, certain public instruments, donations or agreements requiring a notary). In those cases consult your legal advisor before using SignBona.

From Settings › Account. If you forgot it, use password recovery. You'll receive a link by email to set a new one.

Yes. In Settings › Brand you can define company name, logo, primary color, reply-to address, and a custom footer for the emails your recipients receive.

From Settings › Account › Delete account. Deletion has a 30-day grace period during which you can cancel it. After that period your personal data is deleted in accordance with the Privacy policy.

Yes. You can exercise the right to portability by writing to privacy@signbona.com. We'll deliver a structured copy of your data.

Check that the address is correct and ask them to look in their spam folder. If their server rejected the email (hard bounce), our system marks it automatically and you'll see a warning on the envelope. Fix the address and resend the invitation.

Codes expire after a few minutes for security. Click Resend code on the signing page to get a new one.

Check that you're using the correct email. After several failed attempts we may temporarily block access for security; wait a few minutes or use password recovery.

Some PDFs generated by old software may not follow the standard. Try regenerating it from the original document (for example, exporting to PDF again) or open it in another viewer to rule out local issues.

Write to support@signbona.com or use the contact form. Tell us your account email and, if relevant, the envelope identifier. We respond in less than 24 hours on business days.
