Legal signature with legal validity in Odoo

The digitization of documents is key in any ERP, but the legal validity of signatures remains a major challenge for many companies. To address this need, Data Analysis Consultores presentsLegalSign, a module that integrates signatures with full legal guarantees under the eIDAS regulation in Odoo. In September, Contaldia will host an exclusive webinar to showcase its full potential, but we already have the first preview in video.

Webinar Spoiler

We briefly explain an introduction to what we will see in the Webinar so you can understand its objective and ask any questions you may have during the live session in September.

When closing contracts, confidentiality agreements, or informed consents (for example, in the clinical sector), legal security is non-negotiable. However, as José Ramón Serrano, manager at Data Analysis Consultores, explains, the native signature tool in Odoo (both in its Community and Enterprise versions) has certain limitations. Primarily, it lacks the ability to uniquely identify the signer and to ensure through robust evidence that the document has not been altered after signing.

To close this gap,LegalSign, a powerful integration developed for Odoo that elevates document signing to the level ofAdvanced Electronic Signature, fully complying with the demanding European eIDAS regulation.

Two modalities to adapt to any businessLegalSign relies on trusted top-tier providers (such as VIDsigner from Namirial) to offer two main workflows:

  • Remote Signature:Ideal for sending contracts to clients located anywhere in the world, collecting evidence from their device, IP, and location.

  • Biometric Signature:Designed for in-person environments (such as public service counters or clinics). It allows sending the document from Odoo directly to a specific tablet in the room, where the client signs using a biometric stylus.

A transparent and automated use caseIn the recent demonstration released by Data Analysis Consultores, the fluidity of the system can be observed. From the usual Odoo template interface, the user selects the signature field, chooses the "Biometric Signature" option, and sends the request to a specific device (for example, a Lenovo tablet at reception).

Once the client reads and signs the PDF on the tablet, Odoo automatically receives not only the signed document but also the crown jewel of this development:The Evidence Document. This attached PDF contains the complete audit trail: cryptographic hashes, model of the tablet and stylus, operating system version, and the encrypted biometric data of the signature (such as speed and pressure of the stroke), ensuring that any signed document is fully defensible in court.

Great Webinar in SeptemberIf you want to learn in depth how LegalSign can transform the document and legal management of your company using Odoo, we invite you to participate in the detailed webinar that we will hold in September in collaboration withContaldia.
