Digital Signature & E-Sign Document Workflow for Odoo

This is NOT an instant apps.odoo.com download. ECOSIRE builds, installs, and supports this module for your specific Odoo instance over a typical 2–4 week lead time. You get a purpose-built, tested addon tuned to your version (17, 18, or 19), your edition, and your signing use cases — not a generic zip you're left to configure alone.

What you get is a dedicated Odoo application built the right way. A new sign.request / sign.template / sign.item model set (models.Model) captures every document, its fields, and its signatory workflow, with computed status fields driven by @api.depends so a request rolls from draft → sent → signed → completed automatically as parties act. Upload any PDF and use a visual, drag-and-drop field editor (built with OWL components over a rendered PDF canvas) to place signature, initials, free-text, checkbox, and date fields exactly where they belong — then assign each field to a named signatory role. Route documents sequentially (signer 2 only receives the request after signer 1 completes) or in parallel (everyone signs at once), with reminder and expiry logic handled by Odoo automated actions and scheduled ir.cron jobs.

Every action is written to a tamper-evident audit trail — timestamp, signer identity, IP address, authentication method, and a document hash — and rendered into a completion certificate via a QWeb PDF report that attaches to the final signed document. For higher-assurance signing, signers verify with an email or SMS one-time password (OTP) before their signature is accepted, integrated through Odoo's IAP/SMS gateway or your own provider. Reusable templates let your team send the same NDA, quote-acceptance, offer letter, or delivery-confirmation in two clicks, and bulk send fires the same template to a whole list of recipients at once.

Security is enforced the Odoo-native way. Access is governed by ir.model.access.csv plus record rules, so an external signer can only ever see and act on the exact document assigned to them and never your wider database. Signature capture pages are served through Odoo's website/portal controllers with token-scoped URLs — no login required for external counterparties, but no lateral access either. Everything is exposed over Odoo's standard XML-RPC / JSON-RPC API and integrates with the chatter, activities, and existing records (Sales orders, Purchase orders, HR contracts, Subscriptions), so a signed document can auto-confirm a quotation or trigger the next step in your process.

Because ECOSIRE builds it, you're not adopting an abandoned marketplace module. You get clean, reviewable source code, documentation, admin training, and a defined support window — and it stays compatible with your chosen Odoo major version. Own your signing workflow, keep your contracts inside your own database, and stop paying per-signature to a SaaS you don't control.
