E-Signature & Document Approval is a build-to-order Odoo module that ECOSIRE designs, develops, installs and supports for your database — not an off-the-shelf apps.odoo.com download. It gives Sales, HR and Legal teams a legally-binding way to send documents for signature, route them through multi-party approval, and keep a tamper-evident record of every action, all inside the Odoo you already run.
Drag-and-drop placement of signature, initials, date, checkbox and free-text fields onto any PDF or QWeb-rendered document
Multi-party signing in sequential order (route A then B then C) or parallel order (all sign at once), configured per template
Tamper-evident audit trail storing a cryptographic SHA-256 hash, timestamp, signer IP and auth method for every signature event
SMS / OTP one-time-password signer authentication for higher-assurance identity verification before signing
Reusable signing templates and saved signing flows so recurring documents (NDAs, offers, SOWs) go out in seconds
Auto-generated QWeb completion certificate (PDF) attached to the Odoo record, summarizing every signer, action and hash
Signers get a clean, mobile-friendly QWeb signing portal where they place drag-and-drop signature, initials, date, checkbox and free-text fields exactly where they belong. Behind the scenes the module is native Odoo: new models built on models.Model with computed status fields (@api.depends), enforced security through ir.model.access.csv plus record rules so each department only sees its own documents, backend views in XML/OWL, and QWeb-rendered signing certificates. Sequential and parallel signing orders, reminders via Odoo's scheduled automated actions, and SMS/OTP signer authentication are all wired into your existing partners, users and mail infrastructure.
Because every signature is stamped with a cryptographic hash, a timestamp, the signer's IP and authentication method, you get an audit trail that stands up to scrutiny — exported as a PDF completion certificate attached to the record. Integrations flow both ways: trigger signature requests from Sales orders, HR contracts, purchase agreements or any custom model, and read/write signing status over Odoo's XML-RPC / JSON-RPC API from external systems.
ECOSIRE builds it to your exact process — your document types, your approval hierarchy, your branding, your compliance requirements — targeting Odoo 17, 18 or 19 on Community or Enterprise. Typical delivery is 2 to 4 weeks from kickoff, and every engagement ships with source code, documentation, training and a post-go-live support window.
Sends quotes, order forms and contracts for signature straight from the Sale Order, and needs deals closed fast without chasing counterparties across email threads or a separate signing tool.
Routes offer letters, employment contracts and policy acknowledgements to candidates and staff, and needs a defensible signed record with authentication tied into Odoo HR.
Owns document integrity and needs multi-party approval routing, OTP-authenticated signing and a cryptographically-hashed audit trail that will hold up under review or dispute.
Wants signing embedded in the existing database — no new SaaS subscription, no data leaving Odoo — with clean security rules and an API to connect adjacent systems.

This is a build-to-order module, not an instant apps.odoo.com download. After a short scoping call we build it against your Odoo 17, 18 or 19 database, targeting a typical delivery of 2 to 4 weeks from kickoff depending on the number of document types, approval routes and integrations you need. You receive a firm timeline before work starts, and we install and validate it in your environment before go-live.
Every engagement includes a post-go-live support and bug-fix window with a defined SLA covering the delivered scope. Within that window we resolve defects, answer configuration questions and assist your admins. We also provide the full source code and documentation so your team can maintain it, and we offer ongoing support or version-upgrade retainers (for example migrating the module to a newer Odoo release) as a separate, optional package.
The module captures the elements that make an electronic signature enforceable in most jurisdictions: signer intent and explicit consent, an authentication step (including optional SMS/OTP), and a tamper-evident audit trail with a cryptographic hash, timestamp and IP for each action, all preserved on a QWeb completion certificate. We configure the consent text and authentication level to your requirements. We are not a law firm, so we recommend confirming specifics with your legal counsel for your industry and region.
It runs on both. We build the module to target Odoo 17, 18 or 19 on either Community or Enterprise. The core signing, multi-party routing, security and audit trail are all delivered in the module itself, so you are not forced into an Enterprise upgrade — though if you run Enterprise we can align it with related Enterprise apps where useful.
Yes. The module hooks into standard Odoo records — Sale Orders, HR contracts, Purchase Orders, Projects — so a user can send a document for signature in one click from those records. It also exposes XML-RPC / JSON-RPC endpoints so external systems, or your own custom models, can create requests, poll signing status and retrieve the signed certificate programmatically. Scope of integrations is agreed during the build.
Everything stays inside your own Odoo database and filestore — documents, signatures, hashes and certificates. There is no third-party signing SaaS in the loop and no per-envelope fee, which is a key reason teams choose an in-Odoo module over an external service. Access is governed by ir.model.access.csv and record rules so each department only reaches its own documents.
